Palt
What Palt is
Palt is a hosted platform for creating and publishing interactive API documentation from OpenAPI specifications. Users can upload Swagger or OpenAPI JSON and YAML files for OpenAPI 3.0 and later, then give readers a browser-based Try It console for testing endpoints. Generated code samples include cURL, JavaScript, Python, Go, and more. Documentation can be published on a custom domain or embedded in an existing site; custom domains are free and include automatic SSL. A visual editor supports colors, fonts, dark mode, HTTP-method colors, and company logos, while endpoint search includes keyboard shortcuts. The Free plan costs nothing and lists three projects, a custom domain, the Try It playground, and basic analytics. Pro is $19 a month per project and adds branding removal, custom CSS, advanced analytics, and priority support. Enterprise pricing is custom. Palt says users retain ownership of their uploaded materials and that it does not store API keys or sensitive request data.
