Why developers are leaving Postman in 2026
Four push factors driving teams to evaluate alternatives: app size, pricing changes, deprecations, and feature gaps.
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
- No Git-native collections — your work lives in Postman's cloud
- No true local-first or self-hosted option for teams
- Heavy desktop client with slow startup and UI bloat
Things Requestly does differently
Git-native by default, flexibility where it matters, and pricing that doesn't punish you for scaling.
Your collections live in Git, not a vendor cloud
Requestly stores collections as plain JSON in your own Git repo. Version them, review them in pull requests, and own them outright. Environments and secrets stay in your repo by default, and you opt in to cloud sync when your team needs it.
- Plain-JSON collections you version and review like code
- No telemetry or background sync without your consent
- Local, cloud, or self-hosted, your data stays under your control
Local, cloud, or self-hosted, your call
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.
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. Typical idle footprint is ~180 MB versus Postman's ~900 MB+.
- 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
One plan. One price. Everything included.
One Pro plan. One flat rate. No add-ons, no usage meters, no extra charges for AI credits or collection runs. What you see is what you pay, and the free plan supports 10 collaborators at no cost, not one.
- 10 free collaborators, 3 Team Projects, no credit card
- Flat Pro pricing, $9/user/month billed annually
- Predictable cost as your engineering team grows

Postman Alternative FAQs
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.
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, lightweight client with a Git-native workflow are the bulk of the people evaluating alternatives.
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.
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. 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.
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.
It depends on the tool. Postman requires a login on every desktop session. Bruno, Hoppscotch, and Yaak work without an account — you download, open, and send requests immediately. Requestly keeps your collections Git-native, stored as plain JSON you version and own no matter how you sign in. Insomnia and Apidog default to account-based workflows but support local-only modes. For teams that live in Git, plain-JSON collections you review in PRs matter more than the login prompt itself.
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.
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.
