Why developers are leaving Postman in 2026
Five push factors driving teams to evaluate alternatives: forced login, app size, pricing changes, deprecations, and feature gaps.
What Postman does well
A familiar API client most devs have used
- Full REST, GraphQL, and gRPC support
- Scripting, environments, and collection runs
- Massive library of public collections
- Broad ecosystem of integrations
Where it starts to hurt
The cost of staying on Postman
- Forced login before you can even send a request
- No true local-first or self-hosted option for teams
- Heavy desktop client with slow startup and UI bloat
Requestly is one of six credible Postman alternatives in 2026. The comparison below covers Bruno, Insomnia, Hoppscotch, Thunder Client, and Yaak alongside Requestly across pricing, OS support, mocking, and team workflows. The right pick depends on whether you prioritize open source, cloud sync, lightweight desktop apps, or team workspaces out of the box.
Things Requestly does differently.
Privacy by default, flexibility where it matters, and pricing that doesn't punish you for scaling.
Start sending requests in 60 seconds.
For developers who want to test, not sign up
Download the app. Open it. Send a request. That's the full onboarding. No account to create, no SSO dance with your IT team, no "sync to continue" dialog blocking your work. Your credentials and environments stay on your machine by default, you opt in to cloud, not out of it.
- Zero-account start, first request in under 60 seconds
- No telemetry or background sync without your consent
- Local collections are plain files you can delete, move, or commit
Local, cloud, or self-hosted, your call.
For teams whose security posture changes by project, not by tool
The only API client that adapts to your security needs instead of forcing you to work around it. Stay fully local with Git. Flip on real-time cloud sync for teammates who don't live in your repo. Or deploy the whole thing on your own infrastructure for compliance-heavy work.
- Local sync: plain files on your machine, version-controlled with Git
- Cloud sync: real-time Team Projects for instant collaboration
- Self-hosted: deploy on your servers, zero data leaves your network
A client built for executing requests. Nothing more.
For developers tired of waiting for the API client to load
A clean desktop client built strictly for executing requests. No embedded AI running in the background, no auto-modification of your headers, no heavy sync engine chewing through RAM. Open the app, hit your endpoint, see the response, the way it used to work.
- Instant startup, ready to send requests the moment it opens
- Low memory footprint that keeps your laptop breathing
- Simple UI with precise control, no auto-modification or noise

Postman Alternative FAQs
Postman Alternative FAQs
What is the best Postman alternative in 2026?
For most teams, Requestly is the best all-round Postman alternative in 2026. It is free for up to 10 collaborators, runs as a ~180MB desktop app versus Postman's ~900MB, and bundles a built-in HTTP interceptor and mock server in the same window as the API client. Bruno is the better pick if you want pure Git-native storage, and Insomnia is the better pick if your stack runs on Kong API gateways. There is no single winner — the right choice depends on whether you prioritize team size, Git workflow, or gateway integration.
Why are developers switching away from Postman?
Four shifts since 2023 have driven the migration. Postman retired Scratch Pad and now requires a login on the desktop app. The free tier dropped to 1 user in 2026, so a second teammate forces a paid plan. The desktop install is roughly 900MB. And the 2025-2026 roadmap has prioritized AI credits over core API client improvements. Developers who want a focused, offline-capable client without an account wall are the bulk of the people evaluating alternatives.
Can I import my Postman collections into a different API client?
Yes. Most modern Postman alternatives support Postman Collection v2.1 JSON import. In Requestly, the flow is one click: export each collection from Postman as Collection v2.1 JSON, then go to API Client, Import, Postman, and drag the files in. Collections, environments, scripts, and tests come across in a single step. Bruno, Insomnia, Hoppscotch, and Apidog also support Postman imports, though fidelity for pre-request scripts varies between tools.
Is Requestly really free, or is it freemium with a trap?
Requestly's free tier is genuinely usable for small teams, not a 7-day trial. It includes 10 collaborators, 3 team projects, 100 collection runs per month, and unlimited collections, environments, and tests. No login is required to use the desktop app. The Pro plan is $9 per user per month billed annually if you want unlimited collection runs and additional team projects. A 3-10 person team can run on the free plan indefinitely.
How do Requestly, Bruno, Insomnia, and Hoppscotch compare?
Requestly is local-first with optional cloud sync, free for 10 users, and bundles mocking and interception. Bruno is open-source and Git-only with no cloud sync at all. Insomnia is Kong-owned, cloud-first, with a 3-user Git Sync ceiling on the free tier. Hoppscotch is MIT-licensed and self-hostable, but browser-first architecture limits some desktop workflows. Each tool asks you to give up something — pick based on whether cloud sync, Git purity, self-hosting, or team size matters most.
Do I need an account to use a Postman alternative?
It depends on the tool. Postman now requires a login on every desktop session. Requestly, Bruno, Hoppscotch, and Yaak all work without an account — you download, open, and send requests immediately. Insomnia and Apidog default to account-based workflows but support local-only modes. For contractors, students, or anyone switching between client machines, a no-login client removes a daily source of friction.
Is Requestly open source?
The core Requestly API client is not open source. The HTTP interceptor and several SDKs are open source on GitHub. If full open-source licensing is a hard requirement — for example, for security audits or self-hosting from source — Bruno (MIT) or Hoppscotch (MIT) are better fits. Requestly does offer a Self-Hosted enterprise option for teams that need data to stay inside their own infrastructure without requiring source-code access.
What makes Requestly different from other Postman alternatives?
Four things line up in one app. The free tier supports 10 collaborators instead of capping at 1. Collections are stored as plain JSON files on disk, so Git, cloud sync, or local-only all work without lock-in. A built-in HTTP interceptor and mock server live in the same window as the API client — no second tool like mitmproxy or Mockoon needed. And the product is maintained by BrowserStack with 300,000+ developers and a 4.5-star rating across 1,700+ reviews, so it does not carry single-maintainer risk.
