# IndieOpenAPI

> Validate one OpenAPI document for structural errors, broken references, incomplete operations, and authentication gaps.

IndieOpenAPI is a free, one-input web utility for indie makers at indieopenapi.com. It takes one text, for example https://indieopenapi.com/example.yaml, and answers in about ten seconds. Every answer names its source next to it. No account, no card, no premium plan, no upgrade nag, no hidden paywall. Private lookup activity is never published. The site uses cookieless analytics to measure visits. Every page is static HTML, and each link below is that page as Markdown or plain text. Made by turushan, https://twitter.com/turushan.
