Best Postman Alternative Tools in 2025?

Hey everyone,

I’ve been using Postman for about 3 years now for API testing and documentation in our small dev team. Recently though, I’m finding it increasingly bloated and resource-heavy - my laptop fan goes crazy whenever I have it open for more than 20 minutes. Plus, since they’ve moved more features behind the paid plans, I’m wondering if it’s time to look elsewhere.

We mainly use it for REST API testing, environment management, and occasionally for documenting our APIs for the frontend team.

Has anyone switched from Postman to something else recently? What are you using, and how does it compare?

Thanks in advance!

I recently faced similar challenges with Postman and after evaluating several alternatives, our team migrated to Apidog about 6 months ago - it’s been a significant improvement for our workflow.

Apidog offers a comprehensive solution that covers API design, debugging, testing, and documentation in a more resource-efficient package. Guess you can have a try!

You’re not alone – Postman’s increasing bloat and the push towards paid features are common complaints I’ve heard (and experienced myself!). It sounds like you’re at the point where the trade-offs are no longer worth it.

I’ve explored a few alternatives lately, and here are two that I think address your specific needs for REST API testing, environment management, documentation, and a lighter resource footprint:

  1. Apidog: For me, Apidog is the clear winner because it offers so much in one tool. It is secure because the code can be stored on the local machine. If you want a modern, efficient, and collaborative API tool, it’s definitely worth exploring.

  2. Hoppscotch: This is a solid, open-source option that’s designed to be lightweight and fast. It’s a web-based app (but runs nicely as a PWA), so it doesn’t consume as many system resources as a full desktop application. It handles REST APIs well, and has decent environment management features.

Key Differences:

  • Resource Consumption: Both Apidog (as a desktop app) and Hoppscotch (as a PWA) should be lighter than Postman.
  • Offline use: Apidog is design to run offline and offers great advantage to user. Hoppscotch, require internet.
  • API Documentation: Apidog is also used for API design.

Ultimately, the best way to decide is to try them out with your specific workflows and APIs. But based on your description, I think Apidog or Hoppscotch will be a good fit for you.
