Hey everyone,
I’ve been rethinking some of my API tooling recently, especially as I spend more time working in Linux-based environments and open-source workflows.
One thing I’ve noticed is that I’ve been sticking with Postman out of habit, but the free plan limitations make it less practical than it used to be for anything beyond solo use.
For simple API testing it still works fine, but once you need even basic collaboration (sharing collections, working across a small team), it starts feeling a bit restrictive unless you upgrade.
So I started looking again at alternatives that might fit better in a more “FOSS-friendly” workflow:
-
OpenAPI-first setups with Git-based versioning
-
lightweight tools like Bruno or Insomnia for local testing
-
CLI-based workflows (curl + scripts, HTTPie, etc.)
-
or other GUI tools that stay simpler and more transparent
I also tried a couple of newer tools like Apidog, which feels closer to an all-in-one approach (design + testing + collaboration), but I’m still not sure how it compares long-term with more minimal or open workflows.
Curious what others here are using in 2026.
Are you still using Postman, or have you moved toward something more lightweight or open-source aligned?
Would love to hear what actually works well in real Linux setups.
