Built in Rust. Given back.

FastYoke is built in Rust — end to end, no exceptions. When we hit a gap in the ecosystem, we built the library ourselves. And then we gave it back.

We believe the Rust community grows strongest when production teams publish the crates they actually depend on — real libraries, solving real problems, maintained to production standards.

FastYoke's open-source program is that commitment in code. Every crate here was extracted from the live platform, not written as a demo. Each one fills a gap we couldn't find elsewhere in the ecosystem. We'll keep shipping them as we pull them out.
