Reviewer scorecard
“This is the kind of tool that makes you wonder how you worked without it.”
“It has gotten bloated over the years but the core functionality is unmatched. The AI features are genuinely useful, not just checkbox items.”
“The free tier is genuinely usable. Rare for this category.”
“Still the best API development environment. Postbot generating tests from your API schema saves hours. Collections shared across teams are essential.”
“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.”
