Why we open source

Give back to the tools that built us

Every project we ship relies on open source. React, Next.js, FastAPI, PostgreSQL -- we did not build those, but we benefit from them every day. Open sourcing our own tools is the simplest way to return the favor.

Attract developers who care about craft

The engineers who contribute to open source are usually the same ones who write clean, maintainable production code. Publishing our work publicly is a better hiring signal than any job description.

Build trust with clients before a contract is signed

When a potential client can read our code before they hire us, the trust conversation changes. We have nothing to hide and we think that matters.

Contributing

All repositories follow standard GitHub contribution workflows. Open an issue before starting a large feature so we can discuss direction. Pull requests should include tests and a clear description of the change. We review and respond within 72 hours.

We welcome first-time contributors. Issues labeled good first issue are kept intentionally small and well-documented. If you get stuck, open a discussion thread and someone from our team will help you through it.

Consistent contributors get credited in release notes and, if they are interested, we are always looking for engineers to work with professionally.
