One API for LLM, Image, and Video Generation

Use SandBase as a unified AI API instead of integrating and maintaining a separate provider for every modality:

• LLM API: call chat, reasoning, coding, and embedding models through a unified interface, including an OpenAI-compatible endpoint.
• Image API: generate and edit images with models such as Flux through a consistent job API.
• Video API: run video generation models such as Kling with asynchronous jobs and production-ready status handling.
• Tools and data APIs: add web search, scraping, social, business, finance, and other real-world capabilities with the same SandBase account.

Connect your coding agent

SandBase CLI detects your installed clients and configures the MCP bridge for Codex, Claude Code, Cursor, Windsurf, Gemini CLI, OpenCode, and more:

brew install sandbaseai/tap/sandbaseai-cli
sandbase connect

Or run the immutable release directly:

npx -y https://github.com/sandbaseai/cli/releases/download/v0.1.17/sandbaseai-cli-0.1.17.tgz connect

Preview all 25 supported client targets without signing in or changing files:

npx -y https://github.com/sandbaseai/cli/releases/download/v0.1.17/sandbaseai-cli-0.1.17.tgz catalog --json

Operate DeepSeek Harness from evidence

When a DSH install, Session, tool call, sandbox, or plugin fails, use the independent DeepSeek Harness Handbook to find the first broken boundary. It currently provides 143 English-canonical, source-backed guides plus local browser tools that do not upload diagnostic input.

Why SandBase

Modern agents are no longer just chat interfaces. They call tools, run code, inspect files, browse the web, trigger workflows, and act on behalf of users.

That creates a new infrastructure problem:

• where does generated code run?
• which tools can the agent call?
• who is the agent acting for?
• what happens before a sensitive action runs?
• how do teams observe, replay, and debug agent behavior?

SandBase is built around those runtime questions. The open-source path starts with local-first managed agents; the hosted SandBase platform adds managed sandboxes, team controls, observability, connectors, and production support.

What We Build

Area	Focus
Agent runtime	Sessions, event logs, replay, memory, and resumable agent execution
Tool governance	MCP/tools, permissions, approval patterns, and action policies
Sandboxed execution	Safer code, shell, file, browser, and workspace operations
Multi-executor support	Runtime patterns that can work across Claude, OpenAI, local models, and custom executors
Observability	Logs, audit trails, status, and operational surfaces for agent runs
Open resources	Ecosystem maps, cookbooks, labs, and growth playbooks for builders

Builder Topics

We care about infrastructure that helps agents act safely and reliably:

• agent runtime and execution boundaries
• MCP servers, tool protocols, and action schemas
• sandboxed compute for code, shell, browser, and file operations
• model gateways and multi-model routing
• evals, tracing, replay, and observability
• authorization, approvals, and pre-action policy checks
• long-running workflows and distributed execution for agents

If you are building in this direction, we would love to learn from you.
