Generate Markdown API documentation from OpenAPI specs with endpoints and examples. Publish clean reference docs fast — local conversion, free, no signup.
Convert Postman collections to OpenAPI 3.0 specs. Migrate your API documentation. Code never leaves your device — formatting and validation run locally in your browser.
Send HTTP requests from your browser — custom headers, bodies, params, saved collections, and one-click cURL/Fetch/Axios snippets. Developers debug a REST endpoint without leaving the tab — runs locally, free to start.
Compute conversion rate from visitors and conversions with presets, history, and CSV export. Turn 2% into 3% deliberately — free, local, no signup.
Encode SVGs to Base64 data URIs for CSS embedding — icons without requests. Inline a logo in one line — local encoding, free, no signup.
Paths become requests with methods, parameters, auth schemes, and examples — a 50-endpoint spec imports as an organized collection with folders per tag.
Bearer, Basic, API key, and OAuth2 definitions map to Postman auth helpers. Re-enter live secrets after import — specs carry placeholders, never tokens.
Server URLs become environment variables (dev/staging/prod) for one-click switching. Define the three environments before importing.
No — conversion runs locally in your browser. Specs never leave your device.
Postman Collection Generator
Generate Postman collection JSON from endpoint descriptions. Create ready-to-import collections with method and path for each endpoint.
OpenAPI Validator
Basic structural check for OpenAPI/Swagger specs — required top-level fields, non-empty paths, and $ref presence. A heuristic screen, not a full spec validation: passing here does not guarantee a valid spec.
