Reviewer scorecard
“Clean UI, open source, and supports every protocol. The git-based sync is useful for teams.”
“The most mature AI API with the largest ecosystem. Function calling, JSON mode, and assistants API cover every use case.”
“Lighter than Postman and open source. For most API development needs, it's the right balance of features.”
“Reliability has improved significantly. The ecosystem and tooling around OpenAI's API remain unmatched.”
“Functional but the UI isn't remarkable. It gets the job done without inspiring joy.”
“OpenAI set the standard for AI APIs. The Assistants API and real-time API point toward increasingly capable agent platforms.”
