/dev/fast

/dev/fast is an AI-native code forge — code review, deployment infrastructure, and hosting rebuilt for the AI era. The product reframes code hosting, review, and CI/CD around software written and shipped by agents: an RFC-style review surface optimized for human taste and judgement, a multi-agent software factory that dispatches, supervises, and merges work from many cloud agents, agent-native CI/CD where the agent writes declarative pipeline code testable locally, and a fine-grained permission system, with every agent run captured and replayable. Founded in 2025, /dev/fast is a Y Combinator Winter 2026 company based in San Francisco, currently invite-only. It was added to the API Evangelist network as a Y Combinator portfolio lead and enriched from its public surface; no public API, developer documentation, or machine-readable specification is published yet.

/dev/fast is profiled on the APIs.io network. Tagged areas include Company, Developer Tools, Code Review, Code Hosting, and Deployment.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/devfast: open an issue to ask a question, or submit a pull request to add artifacts.
