Why this exists
Anthropic acquired Stainless and shut it down. OpenAI, Google, and hundreds of small startups had their SDKs generated by Stainless. They have until September to find a replacement. This is the simplest possible alternative — paste your spec, get a ZIP. No account. Built in 24 hours.

v0.1 known limits (be honest)
- Complex schema features (allOf composition, discriminated unions, recursive refs) fall back to
dict/map[string]interface{}. - Python and Go are template-based — readable but less idiomatic than Stainless output. Refine the generated code as needed.
- No auth helpers wired automatically. Read the spec's
securitySchemesand pass headers via the client constructor. - Vercel serverless 60s timeout. Very large specs (>500 operations) may time out.
- YAML specs: paste the URL, not raw YAML. JSON paste works directly.
