Best Postman Alternatives in 2026: 9 Tools Compared

Bruno is our pick for most developers leaving Postman. It is an open source desktop client that stores collections as plain-text files in your project, so you can branch, diff, review, and merge API work with Git, just like code. No cloud sync, no account, and no login are needed for core use, which also helps with security and data control.

Bruno imports Postman collections, supports environments and variables, and runs on Windows, Mac, and Linux. Paid Pro, listed from $6 per user per month in recent reviews, adds team and enterprise features. The trade-off is that Bruno is a client, not a full platform, so built-in documentation and cloud mocking are thinner than Apidog. For developers who want a fast, local client, Bruno is hard to beat.

Hoppscotch is the best browser alternative to Postman. Open it in a tab, send a request, and inspect the response without installing anything. It is open source, with a large community, and it can be self-hosted for free if your team wants full data ownership. That combination suits teams that work across machines or cannot install desktop apps easily.

Cloud team features, such as shared workspaces and advanced collaboration, need a paid plan, listed from $6 per user per month in recent reviews for organisations. Self-hosting avoids that cost but needs server setup. For quick testing, demos, and open source workflows, Hoppscotch is fast and flexible.

Insomnia, maintained by Kong, is a mature API client with a clean interface for REST, GraphQL, gRPC, and WebSockets. It handles environments, authentication, and request chaining well, and it imports Postman collections for migration. Local-only projects, available since version 8.3 as noted in reviews, let you work without cloud sync.

Collaboration on the free tier is limited to individual use, with paid plans from $12 per user per month as listed in recent reviews for team features. If you work solo or in a small team that can share files, Insomnia's free tier is strong. If you need cloud team workspaces, compare its paid tier with Apidog and Hoppscotch.

Apidog is the closest full-platform replacement for Postman in this list. It combines visual API design, debugging, mocking, automated testing, and interactive documentation in one workspace. Its free plan, as listed in recent coverage, supports up to 4 users with real-time collaboration, which is more generous for small teams than Postman's current free tier.

That breadth makes Apidog heavier than Bruno or Hoppscotch, so solo developers who only need to send requests may prefer a lighter client. For teams that need docs, mocks, and tests alongside requests, Apidog saves the cost of separate tools. Check the current free and paid tiers on its pricing page, since team limits change.

Thunder Client is a VS Code extension that brings API testing into the editor. You can send requests, manage collections, and test endpoints without leaving your code. That workflow suits developers who spend most of their day in VS Code and want to keep API work next to the code it tests.

Free use covers basic requests and collections, with a Starter plan from $3 per user per month as listed in recent reviews for higher limits. Thunder Client is VS Code only, so developers on other editors should use Bruno, Hoppscotch, or Insomnia instead. For VS Code users, it is the lowest-friction alternative.

HTTPie started as a command-line tool for sending HTTP requests, and it remains a favourite for terminal-first developers. The CLI is free and open source, with readable output, JSON support, and authentication helpers. A web app and desktop app extend the same workflow for users who prefer a graphical interface.

Paid desktop plans start at $5 per user per month as listed in recent reviews, mainly for collaboration and advanced features. The CLI itself stays free, so developers who live in a terminal can use HTTPie without paying. If you prefer a graphical client, Bruno or Insomnia will feel more familiar.

Yaak is a newer local-first API client that focuses on speed and privacy. Collections live on your filesystem, no account is needed for core use, and it supports REST, GraphQL, and gRPC. That local-first approach appeals to developers who want Bruno-style control with a different interface and workflow.

As a newer tool, Yaak's plugin ecosystem and team features are less mature than Insomnia or Apidog. For solo developers and small teams that share collections through files or Git, Yaak is a clean, fast option. Check its current pricing page for any paid team tiers before adopting it for a larger team.

SoapUI, from SmartBear, is the enterprise pick for teams that still work with SOAP APIs alongside REST. Its open source version supports functional testing, assertions, and load testing, which goes beyond simple request sending. That depth matters for legacy systems, banking integrations, and other SOAP-heavy environments.

The interface feels dated, and setup is heavier than Bruno or Hoppscotch for a quick test. SoapUI is not the best choice for a developer who only needs to send a few REST requests. For teams that must test SOAP services, automate functional tests, and run load checks, SoapUI remains a proven, free starting point, with a paid ReadyAPI upgrade for larger teams.

Kreya is built for gRPC, which sets it apart from general API clients. It handles server reflection, streaming calls, and gRPC project organisation natively, rather than treating gRPC as an add-on. That focus helps backend teams that build microservices with gRPC and need to test streaming and metadata reliably.

For REST-only work, Kreya is less compelling than Bruno or Insomnia, since its strengths lie in gRPC. For gRPC-heavy teams, Kreya's free tier covers core testing, with paid plans for team features. If your APIs are mostly gRPC, shortlist Kreya alongside Insomnia and Yaak, and test streaming support with your own services.
