We build tools that
make developers faster
Ferrum Labs is a 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.

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 Ferrum Labs tomorrow, every SDK we built for you keeps working exactly as it did. Forever.
Why "Ferrum"?
Ferrum is the Latin word for iron — element 26, symbol Fe. Iron is the foundation of steel, the most useful alloy in human history. We build the foundational tooling that holds everything else together. It also sounds like forum, a place where things get built in the open. We liked that.
