Reviewer scorecard
“The REST API description standard. Every API should have an OpenAPI spec. The tooling ecosystem is massive.”
“Still the best API development environment. Postbot generating tests from your API schema saves hours. Collections shared across teams are essential.”
“OpenAPI specs are documentation, testing, and client generation in one file. Non-negotiable for REST APIs.”
“It has gotten bloated over the years but the core functionality is unmatched. The AI features are genuinely useful, not just checkbox items.”
“OpenAPI specs are increasingly important as AI tools consume APIs. Machine-readable API descriptions enable AI integration.”
“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.”
