We build tools that
make developers faster
We are a small developer tools studio. We find the repetitive, high-effort parts of the software workflow and replace them with something better.
No lock-in, ever
The code we generate is yours outright. Plain, standard, idiomatic — no proprietary runtime, no calls home, no dependency on us to keep it running. Take it and go.
Speed matters
Days of manual SDK work become seconds. Not "faster" in a marketing sense — literally from spec to publishable package in under a minute.
Self-serve first
No sales calls, no waitlists, no invite codes. Open the app, paste your spec, get your SDK. We believe in letting the product speak for itself.
Our products
Every tool we build starts with a problem we've felt ourselves.
ferrumSDK
LiveGenerate production-ready SDKs in TypeScript, Python, Go, Java, C# / .NET, PHP, and Ruby from any OpenAPI spec, along with an optional Model Context Protocol (MCP) server for AI agent tool integration. Fully typed, idiomatic, and ready to publish. You own every file — no strings attached.
Try ferrumSDKFull-stack app builder from a prompt — production UI, backend, auth, and deploy, without starting from a blank repo.
Our lock-in commitment
There will never be lock-in. That's not a feature — it's a design principle we won't compromise on.
The SDK we generate is plain code in your language's standard package format. No proprietary types, no SDK wrapper, no calls back to us.
Publish it to npm, PyPI, crates.io, Maven Central — wherever your users expect to find it. We're not in that chain.
If you stop using ferrumSDK tomorrow, every SDK we built for you keeps working exactly as it did. Forever.
Why "ferrum"?
Ferrum is Latin for iron. Our tools — ferrumSDK and ferro64 — are named for it because the point is durable output: source code you own and can build on, not a runtime you rent.
