Why Developers Are Ditching Postman (And What to Use Instead)

What actually pushed people away

It was not one thing. It was a slow pile-up:

• The account wall. Back in 2023 the desktop app started nudging everyone hard toward logging in, and some people reported losing easy access to their own collections. Trust took a hit that day and never fully recovered.
• Cloud by default. Your requests, and sometimes your variables, sync to Postman’s servers unless you are careful. If a request carries a real token, that makes security teams nervous. A few of them banned it outright.
• Feature bloat. Mock servers, monitors, flows, an API network, AI add-ons. Great if you live in Postman. Heavy if you just want to fire a GET and read the JSON.
• The free plan got smaller. As of March 2026 the free tier dropped to a single user. For a solo dev that is fine. For a small team it was the nudge out the door.

None of this makes Postman bad. It makes it a platform, when a lot of people wanted a tool.

The alternatives people actually move to

Hoppscotch

The one you hear most. It is web-based, fast, open source, and the usual description is “Postman without the bloat.” Opens in a browser tab, has REST, GraphQL, and WebSocket support, and works as a PWA. If you want a like-for-like replacement with collections and environments, start here.

Bruno

The favorite of people who got burned by cloud sync. Bruno is offline-first and stores your collections as plain text files in your repo, so they live in git next to your code. No account, no server. Reviewing an API change in a pull request is suddenly a normal thing. The tradeoff: it is a desktop app you install, and the ecosystem is younger.

Insomnia

Long-standing, strong on GraphQL, nice UI. Worth knowing it had its own forced-login controversy, so check the current state of its free tier and offline mode before you commit.

Thunder Client

Lives inside VS Code, which is lovely if you never want to leave the editor. Some features moved behind a paid plan, so read the pricing before you lean on it for a team.

When you don’t need any of them

Here is the part most “best alternative” lists skip. A huge share of the time, you are not building a test suite. You want to send one request, look at the response, and move on. Installing and configuring a whole client for that is overkill.

That is the gap the JustInBrowser API tester fills. It runs in a browser tab. No install, no account, nothing synced to a server. Set your method, headers, auth, and body, hit send, read the formatted response. You can paste a cURL command to rebuild a request, or export your request as cURL or a fetch snippet to drop into code. For the “I just need to check this endpoint” case, it is the shortest path from question to answer.

I will be straight about what it is not. It does not sync collections across a team, it is not a CI test runner, and because it runs in your browser it hits the normal CORS wall on APIs that do not allow your origin (there is an opt-in proxy toggle for that). If you need shared workspaces and automated runs, use Hoppscotch or Bruno. If you need speed and zero setup, the browser tester wins. I keep both, and reach for the browser one far more often than I expected to.

So which should you pick?

A rough guide, based on what you are actually doing:

• Quick one-off check, or a machine where you cannot install anything: a browser API tester.
• You want collections in git, no cloud, ever: Bruno.
• You want a familiar Postman-style web app without the weight: Hoppscotch.
• You live in VS Code: Thunder Client.
• You genuinely use mock servers, monitors, and team flows: honestly, stay on Postman.

FAQ

What is the best free Postman alternative?

Depends on need. Hoppscotch for a full web-based client, Bruno for offline/git-based collections, and a browser API tester for quick no-signup requests.

Is there a Postman alternative with no signup?

Yes. The JustInBrowser API tester needs no account and stores nothing on a server. Bruno also works fully offline without an account.

Why did developers stop using Postman?

Account prompts, cloud-by-default data handling, feature bloat, and a shrinking free tier. For simple testing it became heavier than the job required.
