ReadMe.io charges $99+ a month, about $1,188 a year, essentially to render a JSON file and host it. Docsmith renders it once on your own machine: a three-pane, Stripe-style reference with try-it-out, auto-generated curl/JavaScript/Python snippets and versioning, exported as static files you host anywhere for $0. Pay $29, once, and your spec never leaves your desk.

• Import OpenAPI / Swagger — Load OpenAPI 3.x or Swagger from a file or URL, JSON or YAML, with $refs fully dereferenced.

• Stripe-style 3-pane layout — Endpoint nav grouped by tag, full descriptions with parameters and schemas, and code samples beside live response examples.

• Try-it-out that works — Requests fire from the app main process so there is no CORS pain, returning status, timing, headers and a pretty-printed body.

• Auto-generated snippets — cURL, JavaScript fetch and Python requests per endpoint, with path params filled from spec examples and auth headers included for secured endpoints.

• Custom branding — Bake your product name, logo text, primary color and default base URL into every export.

• Static export — One click or one CLI command produces a self-contained folder you host free on Netlify, GitHub Pages, S3 or nginx with your own domain.

• Versioning — Keep multiple spec versions with a switcher in the nav.

Runs as a Windows desktop app.
