Backend for AI agents
Your agent ships a real backend, no signups.
When an AI coding agent builds an app, it hits a wall: the app needs a database, auth, storage, and a place to run, each behind its own signup and dashboard. Cohesivity is one HTTP API that lets the agent provision all of it in a single call, with the provider keys held server-side. You claim the project when you are ready.
the signup wall
Agents can write the app. They cannot sign up for the backend.
A capable agent can build a full-stack app end to end, until it needs a real database, a bucket for uploads, a login system, or somewhere to deploy. Every one of those is a separate account, a card on file, and a key to paste. The build stops so a human can go sign up. Cohesivity removes that wall: one place holds the provider accounts, and the agent reaches them over a single API.
one API, the whole backend
Everything the app needs, provisioned by the agent
Each service below is set up through the same HTTP API and documented on its own page.
- Postgres
A managed SQL database for your app's data.
- Redis
In-memory cache and fast key/value store.
- Vector database
Embeddings storage for search and RAG.
- Object storage
S3-style buckets for files and uploads.
- Hosting
Deploy the app straight from the agent.
- Workers
Run serverless functions at the edge.
- Realtime
Publish/subscribe channels and live updates.
- Authentication
Social login for the app's own users.
- AI gateway
One proxy across model providers.
- OpenAI
Server-side OpenAI access, keys held for you.
- Inbox
An email address the app can send and receive on.
- Browser
A headless browser for automation.
how it works
HTTP in, a working backend out
01
The agent asks
It creates a project and requests a service, a database, storage, auth, with a single HTTP call. No console, no signup.
02
Cohesivity provisions
The resource is created and the real upstream keys are injected server-side. The agent gets back credentials or a proxy endpoint.
03
You claim it
The project runs immediately and is yours to claim with one approval whenever you want to keep it. No signup form before the build.

frequently asked
Backend for AI agents, answered
Yes. An agent like Claude Code, Cursor, or Codex talks to one HTTP API: it creates a project, asks for the services the app needs, and gets back credentials or proxy endpoints. There is no separate human console for provisioning, the agent does it as it builds.
