A modern, cloud-agnostic implementation of TinyWebDB for App Inventor with one-click deployments to multiple cloud providers.
TinyWebDB is a simple key-value web service designed for App Inventor for Android. It provides a RESTful API for storing and retrieving tag-value pairs, making it easy for mobile apps to persist data in the cloud.

Pick the hosting and storage option that best fits your needs:
| Hosting | Database | Deploy |
|---|---|---|
| Cloudflare Workers | KV (Key-Value) | |
| Cloudflare Workers | D1 (SQLite) | |
| Cloudflare Workers | R2 (Object Storage) | |
| Vercel Edge Functions | KV (Redis) | |
| Vercel Edge Functions | Postgres | |
| Vercel Functions | Blob Storage |
Once deployed, make sure you update the ServiceURL property in your TinyWebDB component with the deployed URL. Some
common URL patterns for the providers above are:
- Cloudflare:
https://project-name.account-name.workers.dev - Vercel:
https://project-name-blob3.vercel.app
When setting the ServiceURL, make sure it starts with https:// and does NOT end with /.
Note that Vercel does not "natively" offer a database option (except for the Blob storage). Instead, different
providers are offered in a marketplace.
Still, 1-click deployments, but specific limits may vary from one option within the same "database type" to another
depending on the provider.
