Why Developers Are Switching from Postman

Postman became bloated — slow startup, mandatory cloud sync, paid features behind walls:

Hoppscotch loads instantly — it's a PWA, works offline
No account required — start testing immediately
100% open source — no surprise pricing changes
Lighter than Postman by 10x in resource usage

An API team was frustrated with Postman's mandatory sign-in and sluggish performance. They switched to self-hosted Hoppscotch — their entire test suite runs in CI now via the CLI, and manual testing is instant in the browser.
