PROFULLSTACK, INC. · OPEN SOURCE · MIT

The open source stack for the agentic era

Packages, CLIs, terminal UIs and MCP servers that work naturally for engineers and reliably for the agents they direct. Pulled out of 170 live products, and still running them.

Browse the stack Build an app Start with a prompt

246Packages on npm

31k+Weekly downloads

165k+All-time downloads

230Public repos

170Products running on it

Counted from npm and GitHub on 2026-10-06.

Every surface

A library, a CLI, a TUI and an MCP server where it makes sense. Humans get a terminal, agents get a tool, and both call the same code.

Agent native

Written for the agentic era. The whole stack is one curl away as Markdown or JSON, so an agent can read the rules before it writes a line.

Proven in production

Nothing here is a demo. Each package was pulled out of a live product after a second product needed it, and the fleet still runs on it.

Open and portable

MIT licensed, on npm, self hostable. Bare metal or Railway, Turso or Postgres. No vendor holds the keys.

The libraries

Every one is on npm under MIT. Pick the pieces you need; they do not require each other.

Build

The app layer: shared modules, accounts, data, terminals and media.

Stack

Shared modules for Next and Node apps: referrals, email, payments and CrawlProof in one import.

The blueprint

Profullstack runs about 170 active repos on a small number of deliberate combinations. Pick the combo that matches the job, inherit the shared defaults, follow the house rules, and reuse the published packages before writing anything new.

Pick a combo

There is no single stack. Match the job to a combo, then apply the shared defaults and the house rules.

A new product with a web UI

web-app Next 16 on Turso with a Hono API inside the app. This is the default for anything new.

A change to an existing SaaS on Supabase or Postgres

web-app-postgres Stay on the database it has. Do not migrate an app to Turso as a side effect of a feature.

A real-time 3D game, in the browser and on the desktop

games Babylon on a pure rules core, server-authoritative multiplayer, and art generated by committed scripts rather than modelled by hand.

An API, crawler, poller or data service with little or no UI

api-service Hono on Turso, Bun or Node, one Railway service with a health check.

A command-line or terminal tool, or an agent-facing bridge

cli-tui Node, TypeScript, commander, hqtui for dashboards, MCP where an agent should drive it, published to npm.

A desktop app

desktop Electron with the CLI bundled inside it, so one install gives both surfaces.

A mobile app

mobile Expo inside the product monorepo, sharing the API and packages.

Code two or more products need

library A runtime-neutral @profullstack/* package with subpath exports, released from GitHub.

Something that must be a single fast binary

systems Rust (tokio, axum, clap), or Go when the upstream ecosystem is Go.

Shared defaults

Every combo inherits these. A combo below only lists where it differs or adds.

Concern	Choice	Notes
Language	TypeScript, ESM	"type": "module" everywhere. Kebab-case filenames, semicolons, printWidth 100. JavaScript with JSDoc is fine in small packages.
Runtime	Node 22 or 24 (floor is 20)	Bun 1.4 where the repo pins it in packageManager. Runtimes are managed with mise on dev boxes.
Package manager	pnpm, pinned in packageManager	Bun on Bun repos. Never mix lockfiles. Workspaces via pnpm-workspace.yaml for monorepos (apps/, packages/, services/).
Hosting	Railway	One project per product, railway.json per service with healthcheckPath, deploys on push to the default branch. Custom domain before any URL is written down.
Web server	Caddy	Hosts, reverse proxies and static sites with automatic HTTPS (it gets and renews certificates itself) and IPv6 on by default. Its localhost admin API lets agents and the w3bs CLI add a site without editing config. The default web server on W3BS OS and in front of pit.world and Moshpit names (moshpit-proxy). nginx boxes keep nginx until they are moved.
DNS	Porkbun	No Cloudflare DNS requirement.
Secrets	logicsrc team vault + Railway service variables	Set on the service, record in the vault. No .env files in repos; a framework-required .env.local is a local cache, never the source.
Auth	Magic link + passkeys	The magic link doubles as signup. Passkeys via @simplewebauthn. An optional password only for devices that cannot open mail or hold a passkey (TVs).
Email	Resend	Transactional via the API; @profullstack/emailer for batch with SMTP fallback. Forward Email hosts the mailboxes.
Payments	CoinPay (crypto) and x402	Crypto through @profullstack/coinpay. x402 sells access to agents and crawlers, settled by CoinPay. No Stripe and no card checkout.
Crawler policy	@profullstack/x402-gateway + @profullstack/throttle	Training crawlers get 402 with a daily pass to buy, robots.txt is generated from the same lists, and every route is limited to 100 req/min with a price instead of a 429.
Media playback	@profullstack/player	Every audio and video player: MP4, HLS, MPEG-TS and audio with one control bar. `attachSource` when a site keeps its own UI. A third-party player bump that breaks means move to it, not migrate the old player.
Modern CSS	@profullstack/modern-css	Subgrid cards, squircle corners, stuck headers, grid gap rules, height:auto accordions, reading-flow and @function helpers (--fluid, --alpha, --inner-radius) as opt-in classes in the components layer. Reach for these before JS or extra DOM. Every one is progressive enhancement: write the plain value first.
Analytics	CrawlProof stats.js	Every public site loads crawlproof.com/stats.js. Careers pages are fed from CrawlProof.
Referrals	@profullstack/stack/referrals	Tracked in the request proxy, 60/20 split.
Testing	vitest	`vitest run` in CI. `node --test` for small CLIs, `bun test` on Bun repos, Playwright for browser flows.
Lint + format	Prettier + ESLint	Biome or Oxlint where a repo already uses it. Do not add a second formatter to a repo.
CI	GitHub Actions	ci.yml, codeql.yml and threatcrush-scan.yml on every repo. Release after merge with gh release; a merged PR reaches nobody until the release is cut.
AI	Claude via @anthropic-ai/sdk, MCP via @modelcontextprotocol/sdk	Anything an agent should operate ships an MCP bridge. Cheap models for high-volume loops.
Promotion	myna (mynaposter.com)	The last phase of every ship: socials, both blogs and a CrawlProof ad from one command. Syndicated copies carry rel=canonical back to our page.
Data	NicheDB, RSS Amplifier, r4ck	Datasets come from and go back to nichedb.dev. Feeds are submitted through @profullstack/submit-feed. OpenProfile.md for people, /.well-known/openaccess.json for access terms.

Combos

Different stacks for different reasons. Each one names live products built on it.

Web app

web-app

The default for a new product. Next 16 renders the UI, a Hono app mounted inside it serves the API, Turso holds the data, and one Railway service runs web and worker together.

Use it when

You are starting a product that has a UI and a database.
The data fits SQLite semantics: one writer, modest joins, no Postgres extensions.
You want one service, one deploy, one domain.

Notes

Next inlines process.env.NAME at build time, so read runtime secrets through a non-literal key.
A 200 on /api/health proves nothing about the worker. Check the logs for its up line after a deploy.

Built on it

rssamplifier.com p0dcasters c0upons opensourcelegends.com sorrycheck sinkstate bufferoverride nightcell7

Concern	Choice	Notes
Framework	Next 16, React 19	App Router. proxy.ts, not middleware.ts. Server components by default.
API	Hono inside Next	Mounted under /api. Versioned routes live at /api/v1/... and OAuth callbacks at /api/v1/<provider>/<function>/<endpoint>.
Database	Turso (libSQL) via @libsql/client	Forward-only SQL migrations in packages/db, or Drizzle with dialect turso. Migrations must be safe to run twice concurrently.
UI	Tailwind 4 + shadcn/ui	Scoped behind a ui.css without preflight when adding to an existing site. Plain CSS modules on marketing sites.
Realtime	Server-Sent Events	WebSockets only for chat, terminals and multiplayer.
Background work	A worker process in the same container	Supervised by the entrypoint; the container exits non-zero when either process dies. BullMQ on Redis only when the queue is the product.
Storage	Railway volume or Cloudflare R2	R2 buckets private, served through signed or proxied routes.
Layout	apps/web, packages/db, services/worker	Root-only vitest config, tsconfig.base.json with strict flags. Copy nightcell7 or reeleel rather than inventing a layout.

Web app on Postgres

web-app-postgres

The previous generation of the same shape, and still the largest by count. Next 16 on Supabase, or on a self-hosted Postgres in the same Railway project. Kept where the data needs Postgres or the app already lives there.

Use it when

The app is already on Supabase or Postgres. Stay there.
You need row-level security, pgvector, heavy relational joins, or a queue on Redis next to the database.
Several services share one database and the write volume is real.

Notes

Do not move an app to Turso as part of a feature. Classify it first: easy Turso, needs Postgres, or consolidate.
coinpayportal is public with 19 forks. Never put real data in a fixture there.

Built on it

coinpayportal.com ugig.net crawlproof.com marksyncr.com logicsrc.com w3bs.org brisk.news icemap.app

Concern	Choice	Notes
Framework	Next 16, React 19	Same conventions as web-app.
Database	Supabase Postgres, or self-hosted Postgres on Railway	Supabase client via @profullstack/stack/supabase. New Postgres apps self-host on Railway (w3bs.org is the reference). Index every foreign key you will cascade through.
Auth	Magic link + passkeys on the app's own users table	Supabase Auth exists in older apps; the local users.id is always the primary key.
Queues	BullMQ on Redis	Custom job ids must not contain a colon.
Migrations	supabase/migrations or plain SQL	Applied in CI or on boot, never by hand in the dashboard.

API service

api-service

Hono on Turso with no framework in front of it. For pollers, crawlers, data APIs, MCP servers and anything whose UI is a few server-rendered pages or none at all. Bun or Node, chosen per repo and pinned.

Use it when

The product is an API, a feed, a dataset or a daemon.
The UI is small enough to render from Hono (JSX or templates) or lives in a separate app.
You want the smallest possible service: one process, one SQLite file or one Turso database.

Notes

Bun-only gotchas: Bun.serve idleTimeout kills long streams, and Bun's SQL client stringifies arrays. Keep those behind small adapters.

Built on it

nichedb.dev r4ck.dev genrewatch.com tipoffwatch.com watchnews.now agenticjobs tronbrowser.dev reeleel

Concern	Choice	Notes
Framework	Hono 4	Web-standard Request/Response. Same app runs on Bun and Node; the router is the only Hono-specific code.
Runtime	Bun or Node, pinned	Bun for stream-heavy or IO-heavy services (genrewatch, tipoffwatch, niche-db, r4ck). Node + pnpm when the service shares code with a Next app or a CLI.
Database	Turso (libSQL)	Embedded replica or remote. FTS5 for search, with the raw query escaped; libSQL cannot bind undefined.
Rate limiting	@profullstack/throttle	Credentialed callers get 600/min, anonymous 100/min, over the limit is a 402 with an offer.
Agent surface	MCP bridge in the CLI package	One query vocabulary across page, API, CLI and MCP.
Deploy	Railway, Dockerfile or Nixpacks	railway.json with healthcheckPath. Pin pnpm 10 on Nixpacks; corepack cannot launch pnpm 11.

CLI and TUI

cli-tui

Terminal tools for people and agents. Node and TypeScript, commander for arguments, hqtui for anything with a screen, an MCP bridge so an agent can drive the same commands, published to npm under @profullstack.

Use it when

The user is a developer, an operator or an agent.
The tool wraps a site or API we run (nichedb, rssamplifier, coinpay, r4ck, readm3).
You need a dashboard in a terminal rather than a browser.

Built on it

@profullstack/hqtui @profullstack/nichedb @profullstack/coinpay @profullstack/readm3 @profullstack/g1tz @profullstack/r3q @profullstack/billing cli-tools

Concern	Choice	Notes
Runtime	Node 20+ (Bun optional)	Node is required: CLIs run in GitHub Actions and on customer machines. Bun is fine for development.
Arguments	commander	Subcommands map one to one onto MCP tools.
TUI	@profullstack/hqtui	btop-grade dashboards, one import. A mouse must work: one click unfolds, hover highlights.
Config	~/.<tool>.json + @profullstack/synconfig	Allowlisted snapshot synced with the tool's cloud.
Install	npm i -g @profullstack/<tool> and curl \| sh	The installer does the whole job. Never document a manual follow-up step.
Testing	node --test or vitest	bun test on Bun repos; mock.module is process-wide there.
Release	GitHub release workflow publishes to npm	Bump before testing. A brand-new scoped package 404s for minutes after publish.

Desktop

desktop

Electron, with the product's CLI bundled inside the app. A desktop install gives the CLI too, with no system Node, and the two surfaces cannot disagree because they are the same build.

Use it when

The product needs a tray, a window, the filesystem or OS input.
A CLI already exists and the desktop app is a second surface for it.

Built on it

mynaposter diskpush threatcrush pairux.com nixampmedia2markdownr4ck.dev

Concern	Choice	Notes
Shell	Electron	Tauri was tried and retired.
Inside	Hono or Next, same as the web surface	The renderer is the web app; the main process hosts the API locally.
CLI	Bundled via extraResources	The installer writes a shim: ELECTRON_RUN_AS_NODE=1 exec app resources/cli/dist/bin.js. Build the bundle with pnpm deploy --prod --legacy.
Native modules	N-API only	Electron's ABI differs from system Node. @libsql/* passes; anything with V8 symbols does not.
Distribution	GitHub releases + curl installer	Headless machines get a CLI-only tarball. Homebrew, apt, rpm, scoop and nix repos exist for pairux.
Auto-update	From GitHub releases	Set the tool's NO_AUTO_UPDATE env when testing a dev binary.

Games

games

Babylon in the browser, with every gameplay rule in a package that cannot import a renderer. The same rules run in the client, in the authoritative match server and in tests, so a rule exists exactly once.

Use it when

The product is a real-time 3D scene the player acts inside, not a page they read.
It has to run in a browser first, with the desktop build as a second surface rather than the only one.

Notes

Distant point lights and glows are camera-facing sprites held at a fixed screen size, never scaled geometry. A 25 mm firefly is sub-pixel past 30 m and no amount of scaling the mesh fixes that.
Budget the shell download. Models ship geometry, UVs and a named material slot; the engine binds the real textures by that name so one atlas is not shipped ten times.

Built on it

nightcell7 nightcell7.com

Concern	Choice	Notes
Renderer	Babylon.js	WebGPU where the browser has it, WebGL2 fallback. The fallback is a supported path, not a degraded one.
Physics	Havok via @babylonjs/havok	Only where real collision response is needed; most props are static.
Rules	A pure game-core package	No Babylon, no DOM, no Electron imports. This is the rule that makes a client and a server able to agree.
UI	Preact, outside the frame loop	The component layer never owns a per-frame transform. HUD readouts are text-node writes behind a change check, not a render pass.
Multiplayer	Server-authoritative over WSS	The client sends input intent. The server owns movement validation, damage, death, respawn and score. Shared messages live in their own protocol package.
Build	Vite + vite-plugin-pwa	Set registerType and actually wire the update prompt; prompt with no handler means returning players never get a new build.
API and data	Hono, Drizzle, Postgres	Same as api-service. Never cache /api, matchmaking or tickets in the service worker.
Desktop	Electron	The desktop combo applies unchanged; the renderer is the same web build.
Art	Generated by committed Blender scripts	No asset without provenance. One Blender metre is one game metre, GLB with glTF-compatible PBR, COL_ colliders and SOCKET_ attachment points.

Mobile

mobile

Expo and React Native, as apps/mobile inside the product monorepo. It shares the API client and packages with the web app rather than living in its own repo.

Use it when

The product needs to be in the app stores or on a phone home screen with native capabilities.
A PWA is not enough (push, background, camera, payments in-app).

Notes

Start with the PWA. Most products never need this combo.

Built on it

threatcrush pairux.com postammo.com reeleel tronbrowser.dev

Concern	Choice	Notes
Framework	Expo (React Native)	React 19. Shares types and the API client with apps/web.
Layout	apps/mobile in the product monorepo	Standalone *-mobile repos are the old pattern and are dormant.
Backend	The product's own api-service or web-app	No separate mobile backend.
Store release	sh1pt	One codebase to every store, registry and channel.

Library

library

Code that two or more products need becomes a @profullstack/* package. Runtime-neutral core, subpath exports, one npm package per concern, released from GitHub.

Use it when

You are about to copy a module from one repo into another.
A site needs a component another site already ships (player, leaderboard, feed submission, contact-form guard).

Built on it

@profullstack/stack @profullstack/x402-gateway @profullstack/throttle @profullstack/player @profullstack/modern-css @profullstack/leaderboard @profullstack/form-guard @profullstack/submit-feed

Concern	Choice	Notes
Shape	ESM, TypeScript, subpath exports	`@profullstack/stack/referrals`, `/email`, `/supabase`, `/feedback`, `/coinpay`, `/crawlproof` is the pattern. Peer-depend on next, react and clients rather than bundling them.
Core	Web-standard APIs	fetch, Request, Response, URL, crypto.subtle, ReadableStream. Runtime-specific code behind an adapter. A /core entry must never import a node: module.
Build	tsup or plain tsc	Node type-stripping needs .ts specifiers; pair with rewriteRelativeImportExtensions so dist still emits .js.
Tests	vitest	Contract tests where the package defines a protocol (x402, submit-feed, OpenProfile).
Release	Bump, merge, gh release	A release workflow publishes. Ship pkg@latest in docs, never update -g. pnpm 11 refuses packages younger than a day unless excluded from minimumReleaseAge.

Systems

systems

Rust when the product is a single static binary that has to be fast (benchmarks, transports, agents on servers). Go when the upstream ecosystem is Go. Python only for security tooling that lives in that world.

Use it when

A JavaScript runtime would be the bottleneck or the dependency you cannot ship.
The upstream you build on is in that language (LiveKit for agentbbs, nmap and Kali tooling).

Built on it

c0mpute agentbbs fiche-agentic vu1nz.com kali

Concern	Choice	Notes
Rust	tokio, axum, clap, reqwest	c0mpute is the reference. Auto-update from GitHub releases on first run.
Go	Standard library + the upstream SDK	agentbbs pins livekit server-sdk-go and protocol together.
Python	Managed by mise, venv per project	Security tooling and GitHub Actions only (vu1nz).
Distribution	GitHub releases, curl installer, homebrew tap	Same installer rule: it does the whole job.

House rules

The conventions an agent has to follow on any Profullstack repo, whichever combo it is on.

Ship it, never stop at in progress

An agent does not end its turn on "still running, I will report when it lands". Work handed to a subagent, CI or a deploy is driven to merged, released and verified live in the same turn, then reported once with the result. Stop early only for a real blocker a person must clear: a login, or a decision that is theirs.

Every site takes payment from launch

Launching a site includes taking crypto: npx @profullstack/coinpay-onboard site <name> --webhook <public url> makes its CoinPay business, copies the payout wallets in, sets the webhook and writes the COINPAY_* keys into the site vault. Idempotent; every step must print a check before the launch is announced.

Launch on a Moshpit name

New products launch on a Moshpit name (pit.moshcode.sh), not a new ICANN domain, served from our own box with a registry-signed certificate and listed on the Moshpit ring. Announcements give the <name>.pit.world address for browsers without Moshpit DNS.

Reuse the house package first

Before adding a dependency or writing a component, grep the repo for @profullstack/ and check npm. The package usually exists and is often already installed.

Secrets live in the vault

Set production secrets on the Railway service and record them in the logicsrc team vault. Never write one into a .env in the repo, and never ask a person to.

Auth is magic link plus passkeys

The link proves the address and the address is the account. Passwords are optional and only for devices that cannot do either.

Installers do the whole job

If a feature needs a component, the installer or update command installs it. No documented manual follow-up step. DNS routing is the one thing that stays explicit.

Push to the default branch deploys

PRs are merged, not parked. Release after merge. Then announce through myna, with rel=canonical on every syndicated copy.

Our domains only

Add the custom domain before writing any URL down. Never publish a *.up.railway.app address.

Migrations run twice

Web and worker both migrate on boot. Ledger writes are insert-or-ignore and every migration is safe to apply concurrently.

Large catalogues use a sitemap index

/sitemap.xml is an index; entities are chunked by month of creation so past files never change.

OAuth callbacks are namespaced

/api/v1/<provider>/<function>/<endpoint>, using whatever API prefix the project already has.

Every product is a customer of another

Wire products together when the integration is load-bearing: x402 settles through CoinPay, blogs open CrawlProof ads, myna distributes every ship, NicheDB sells the data.

Copy has no LLM tells

Short sentences, no em dashes, no rule-of-three flourishes. This applies to posts, READMEs and announcements.

A wedged process restarts without a person

Every container gets a HEALTHCHECK that hits its own /healthz, so a blocked event loop shows as unhealthy. watchdog-autoheal restarts what Docker marks unhealthy, three times an hour at most, then emails. In-process, watchDependencies exits when the shared DB or Redis client stops answering.

Agents get a first-class surface

A site ships its data as Markdown or JSON at a stable URL, a CLI ships an MCP bridge, and training crawlers pay through x402 rather than being blocked.

Not in the stack

Things an agent might reach for by habit. Do not.

Hetzner: Ruled out permanently. Railway hosts the fleet; a netcup box and DigitalOcean droplets cover what needs a VM.
Vercel, Fly.io, Cloudflare Workers: Not deploy targets. One repo has a fly.toml and none have a wrangler config. Railway is the host.
Supabase for a new app: Turso is the default. Supabase and Postgres stay where they already are.
.env files as the source of secrets: The vault and the platform env are the authority. A file is a stale copy.
Password-first auth, next-auth: Magic link plus passkeys. @profullstack/auth-system is password-only and is the exception, not the pattern.
SvelteKit, Primate + SurrealDB, Express for new work: Earlier generations still in maintenance. Do not start anything new on them.
Tauri: Retired in favour of Electron with the bundled CLI.
mocha, jest, Prisma: vitest and plain SQL or Drizzle.
Oxc, Oxlint, Oxfmt, Rolldown as a default: On the roadmap since June and present in six repos. Use the repo's existing lint and format setup until parity is proven.
Hand-rolled players, rate limiters, contact-form guards, feed forms: Each of these is a published package already.
video.js, plyr, a bare hls.js or mpegts.js: @profullstack/player wraps hls.js and mpegts.js already. video.js 10 ships no player at all: it throws VJS8_LEGACY_* on v8 code.
*.up.railway.app URLs: Our domains only.
