OpenAPI-Search combines multiple OpenAPIs in a fast, organized, and searchable interface.
OpenAPIs are effectively closed if there isn't an accessible way to find and use them. Big commercial API directories such as https://rapidapi.com are currently dominating the search results and the # of APIs indexed, leading many developers to a non-open API gateway. Open Source is far behind.
The best OpenAPI directory as of yet is https://apis.guru but this doesn't even reach 10% of the amount of listed APIs and there is many room for improvement.
The vision of https://openapisearch.com is to make OpenAPIs truly open by making it accessible (easy to find what you're looking for) and improving listing quality.

Targeted improvements compared to https://apis.guru:
- Easy navigation for agents
- Programmatic Registry
- Improved Website
- E2E Testing of OpenAPIs
- AI Crawler for API Discovery
- AI Crawler to augment OpenAPI Metadata
- Adds authentication + scope info
- Adds useful links
- Adds reviews
- Adds pricing info, ratelimit info, etc
- Create a docs reference website like readme.com (there are many) - for this we're using stoplight now.
- Add weird custom logic that is non-standard to the OpenAPI. Instead, I aim to create a layer on top of openapis to improve the implementation of the standard. I'll use actionschema for this.
- 2025-03-20 - I did lots of work in this area and left it all behind after moving to cloudflare. It's time to take some of this work and redo it with a new vision, taking in all learnings from the last months. My current intuition is as follows; 1) Don't focus on quantity, focus on quality of a few great OpenAPIs. Make it very easy to build with a particular OpenAPI, for example. 2) People want to see their own OpenAPIs, and aren't interested in 99% of all other OpenAPIs.
