0:00 / 1:13

One home between your agents and your tools.

Any agent builds on OpenBelt. Every tool it makes can reach your services, and no agent sees a key.

Connect once. Use it everywhere.

Connect a service once and every agent and tool can use it. Agents never see your keys.

Everything your tools need, built in.

Nothing to set up. Ask for a feature and your agent wires it in.

Data

Every tool gets its own database. Save data, read it back, and use other tools' data too.

Realtime

Watch a query and the page updates the moment the data changes. No polling.

Functions

Server code that pages, other tools and agents can all call, with checked inputs.

Jobs

Run on a schedule, or later in the background, with nobody waiting.

Webhooks

Take events from GitHub, Stripe or Shopify, with signatures checked.

Users and secrets

Know who's using each tool, and call APIs without exposing a key.

Your first tool is one prompt away.
