Postman, Bruno, and Insomnia all help you send HTTP requests, yet they optimize for different team shapes.
Postman is still the default when collections, tests, and onboarding span roles. Bruno wins when collections should live next to code in git. Insomnia stays relevant as a capable desktop client that feels less platform-heavy than Postman for many solo workflows.
The short answer
Postman for team scale, Bruno for local-first repos, Insomnia when you want a solid middle ground on the desktop.
Top picks
Best Postman vs Bruno vs Insomnia
The breadth of collaboration features is hard to match for distributed teams.
Git-friendly storage is the headline feature that changes daily habits.
A practical balance of power and focus for everyday request work.
Postman is still the team default
When APIs are how multiple groups coordinate, Postman's shared collections and environment patterns reduce repeated questions.
The cost is product complexity. Solo developers may feel like they are renting a platform to run a handful of requests.
Why Bruno took off
Bruno made the collection file a normal artifact. Reviewers can diff requests like any other change.
That aligns with how serious teams already treat infrastructure and config. The client stops being a private silo.
Insomnia's middle lane
Insomnia still fits developers who want a strong desktop workflow without committing to Postman's full ecosystem.
If your needs are straightforward, any of the three can work. The decision is mostly collaboration versus file ownership.
