Reviewer scorecard
“Clean UI, open source, and supports every protocol. The git-based sync is useful for teams.”
“Still the best API development environment. Postbot generating tests from your API schema saves hours. Collections shared across teams are essential.”
“Lighter than Postman and open source. For most API development needs, it's the right balance of features.”
“It has gotten bloated over the years but the core functionality is unmatched. The AI features are genuinely useful, not just checkbox items.”
“Functional but the UI isn't remarkable. It gets the job done without inspiring joy.”
“In an era of AI agents that can call APIs directly, do we still need a GUI for API testing? The future might be AI testing APIs autonomously.”
