ApiForge AI is an API design and SDK generator that turns a plain description of what an API should do into a working integration surface. Launched in October 2026, it is aimed at backend engineers and platform teams who spend more time writing OpenAPI specs, mocks, and client libraries than building features.
Core Features
- Generates an OpenAPI specification from a natural-language description of the endpoint behavior.
- Spins up a mock server so front-end teams can build against the API before it ships.
- Emits client SDKs in up to eight languages from the same spec.
- Builds a documentation site automatically from the generated spec.
- Reverse-engineering mode: feed in real API responses from an existing service and it produces a typed client plus docs.
Use Cases
- Platform teams maintaining large third-party integration surfaces that need fresh typed clients.
- Startups scaffolding a public API and SDKs without hiring a dev-rel writer.
- Contract-first shops that want a mock and docs before writing a line of server code.
Pricing
ApiForge AI offers a free tier that covers three APIs. The Pro plan starts at $29 per month, with enterprise pricing available for larger teams. It competes with spec tools like Postman and Stoplight by folding the SDK step into the same run.
Our Take
Best for teams drowning in integration boilerplate; the trade-off is that very small projects may not need the full spec-to-SDK pipeline. Compare it with other AI coding tools.
