TypeSafe docs, SDKs, playground, and repos they actually maintain.
Start here when you want the real API, not a fork with vibes. Docs, SDKs, playground, evals, and the manifesto. These links are the canonical source for endpoint shapes, pricing notes, and primitive definitions. When you compare latency or file a bug, cite TypeSafe surfaces first. This hub gathers every official entry we index so you can jump to docs.typesafe.ai or the playground without wading through community summaries.
