A backend for a new SaaS feature

A product team needs endpoints for a new module this sprint. Instead of writing CRUD, auth, pagination and docs again, they paste the schema, review the design and deploy to staging the same day.

Start from your existing api database schema.
Ship REST for the web app and GraphQL for the mobile client from one source.
Keep docs and tests in sync as the feature changes.

GET/v1/appointments?sort=-starts_at

POST/v1/appointments

GET/v1/appointments/{id}

PATCH/v1/appointments/{id}

POST/v1/appointments/{id}/cancel

Client backends for agencies and studios

Agencies deliver many similar apps for many clients. APIGenerator turns each brief into a hosted API in a separate project, and the code export gives the client a repository they own.

One project per client, with its own keys and environments.
Code export in Node.js TypeScript, Python FastAPI or PHP Laravel for handover.
Change review on Team, so a junior developer cannot deploy to production alone.

APIs for internal tools and operations data

Operations teams keep data in sheets and small databases. A generated API puts that data behind keys, limits and an audit trail, so internal tools stop reading files directly.

Upload a sheet on excel to api.
Give each tool its own key with its own rate limit.

Connecting AI agents to company data

Data and AI teams need agents to read and update company records without handing them database credentials. APIGenerator generates an MCP server next to the API, with tools that respect the same keys, roles and limits.

Generate a custom MCP server from a schema or an OpenAPI file.
Put every agent behind one mcp gateway with per key permissions.
Expose a database safely with the postgres mcp server.

Real APIs for prototypes

A product manager with a data set needs a working API for a prototype or a pilot customer. Describing it in plain English is enough to get endpoints, docs and a mock server that frontend developers use right away. See instant api.

Selling access to your data

Teams with valuable data publish a paid API with plans and keys for their own customers. Read about the api marketplace module.
