I’m using Postman and it’s getting hard to manage collections, what should I switch to?

If Postman feels like it’s getting unwieldy, the best switch depends on what you mean by “manage collections” and how your team works. A few good alternatives:

Best overall for API design + docs

Insomnia

• Cleaner UI than Postman for many people
• Good for REST, GraphQL, gRPC
• Easier to organize requests in workspaces/collections
• Great for local/dev API testing
• Less “bloat” than Postman for some teams

Best if you want open-source and lightweight

Hoppscotch

• Fast, web-based, open-source
• Simple to use
• Good for quick testing and sharing
• Less feature-rich than Postman/Insomnia for advanced workflows

Best for automation / test-heavy teams

Newman + code-first testing or Bruno

• Bruno stores API collections as files in your repo
• Great if you want Git-friendly API definitions
• Easier to review changes in PRs
• Very good if your biggest pain is collection sprawl and collaboration

Best for enterprise / API lifecycle management

Stoplight

• Strong API design, mocking, docs, governance
• Better if your focus is team-wide API standards
• More than just a Postman replacement

Best if you want to stay in the Postman ecosystem but organize better

• Use separate workspaces
• Split collections by domain/service
• Use folders consistently
• Move shared variables to environments
• Consider exporting collections into Git

My practical recommendation

• If you want the closest “better Postman”: Insomnia
• If you want Git-based, cleaner collection management: Bruno
• If you want lightweight and open-source: Hoppscotch

If you tell me:

1. solo or team use,
2. REST only or also GraphQL/gRPC,
3. whether you want Git integration,
4. Windows/macOS/Linux, I can recommend one specific tool.
