Reviewer scorecard
“One-line integration via proxy is genius. Change your base URL and instantly get logging, caching, and rate limiting.”
“Still the best API development environment. Postbot generating tests from your API schema saves hours. Collections shared across teams are essential.”
“The proxy approach means minimal code changes. Cost tracking alone pays for itself when you have multiple models.”
“It has gotten bloated over the years but the core functionality is unmatched. The AI features are genuinely useful, not just checkbox items.”
“As AI costs become a significant line item, observability and optimization tools like Helicone become 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.”
