The best Postman alternatives in 2026

Why Teams Look for Postman Alternatives in 2026

Postman is still the default API client for a lot of developers. It runs requests, organizes them into collections, runs tests, hosts mock servers, monitors endpoints and now ships an AI agent. For a large organization that wants one governed place for every API, that breadth is the point.

For many smaller teams, though, 2026 gave them a concrete reason to look around. Postman's own documentation says that before March 2026 it offered Free, Basic, Professional and Enterprise plans, and that it now offers Free, Solo, Team and Enterprise. The bigger change sits in one sentence of the same page: the Free plan "is limited to one user and can't create a team." Today, sharing a workspace with even one colleague means the Team plan at $19 per user per month, billed annually. Postman notes that customers on legacy plans keep them until renewal, so many teams are only now hitting the change.

The other long-running complaint is about where your work lives. Postman's lightweight API client works without signing in, and its docs say that work is "stored locally and isn't synced online with Postman." But collections, environments and workspaces are tied to signing in, and for years the main way to share them was Postman's cloud. Developers who want their API requests to sit in the same Git repository as their code, reviewed in the same pull requests, went looking for tools built around files on disk.

To be fair to Postman, it has responded. Its Native Git feature, documented on Postman's learning site, lets you "develop APIs in a local Git repository and sync them to Postman Cloud only when the work is ready to share," with collections, specs and environments stored as files in a postman folder next to your code. It is desktop-app only. If Git workflows were your only reason to leave, check it before you migrate.

So the reasons people leave Postman in 2026 usually come down to three things:

• Cost of collaboration. Any shared workspace now starts at $19 per user per month on annual billing.
• Cloud by default. Signed-in features and team sharing are built around Postman's cloud, which some security teams don't allow.
• Weight. Postman has grown into a full API platform (Spec Hub, Flows, API Catalog, governance, Agent Mode). Developers who only send requests and run tests often want something lighter.

This guide compares Postman with six alternatives: Insomnia, Bruno, Hoppscotch, Thunder Client, Yaak and Stoplight. Earlier lists of Postman alternatives usually included Paw. Paw was renamed RapidAPI for Mac and is now owned by Nokia. Its site carries a notice that upcoming macOS releases, including macOS 27, "will not be tested, certified, or officially supported by Nokia," and its update log shows the last release (4.5.5) in April 2026. We don't recommend starting a new team on a Mac-only client whose owner has said it won't certify the next macOS, so this guide covers Yaak instead: a local-first, open source client from the original creator of Insomnia.

Postman review

Postman is the full API platform in this list. Its product pages group features into design (Spec Hub, mock servers, Flows, workspaces), testing (API client, Collection Runner) and operations (monitors, API governance with a built-in rule library, the API Catalog, the Postman CLI and Agent Mode for AI-driven workflows).

Key features

• API client with collections, environments, scripting and a Collection Runner for test suites
• Mock servers and monitors for simulating APIs and checking them on a schedule
• Spec Hub and API governance for managing specifications and enforcing rules
• Native Git (desktop app) to keep collections, specs and environments as files in a local repository and push to Postman Cloud when ready
• Agent Mode and AI credits for AI-assisted test generation and workflows

Pricing

• Free: $0, one user, 100 AI credits per month, 1,000 monitoring requests per month, 25 Flows credits per month, up to 5 integrations
• Solo: $9 per month billed annually, for one person; 400 AI credits per month, 30-day collection recovery
• Team: $19 per user per month billed annually; 400 AI credits per user per month, unlimited workspace viewers, 90-day collection recovery
• Enterprise: custom pricing; adds API Catalog, Private API Network and advanced RBAC

Postman says annual billing saves up to 25%. SSO is a paid add-on on Team and Enterprise. AI overages are billed per credit.

Pros

• The broadest feature set of any tool here, from request to monitoring to governance
• Built-in mocks, monitors and Flows mean fewer separate tools to run
• Native Git now gives a file-based workflow for teams that want it
• Mature enterprise controls on the top tier

Cons

• No free collaboration at all since March 2026
• Many features are built around Postman's cloud, which some security reviews reject
• Can feel heavy if you only need to send requests and run tests
• AI, Flows and monitoring all have their own usage limits to track

Who should use it

Teams of 20 or more that use more than the API client: monitors, mocks, governance, a shared API catalog. If those features replace other tools, the per-user price is easier to justify.

Who should skip it

Small teams that only send requests and run tests, and any team that can't put API data in a vendor cloud.

Insomnia review

Insomnia is an open source API client (Apache-2.0) maintained by Kong. It covers REST, GraphQL, gRPC, WebSockets and SSE, and adds OpenAPI design, mocking, an MCP client for testing Model Context Protocol servers, and the Inso CLI for running checks in CI.

Insomnia's history is relevant here. Kong's own release notes show that Insomnia 8.0 pushed users toward accounts and cloud sync, and that Insomnia 8.3 brought back fully local projects. Today you choose per project between Local Vault (Kong's docs say "no data is sent to or stored in the cloud"), Git Sync with your own Git provider, or Cloud Sync. A Scratch Pad works without logging in at all.

Key features

• Multi-protocol client: REST, GraphQL, gRPC, WebSockets and SSE
• Storage choice per project: Local Vault, Git Sync or Cloud Sync, with optional end-to-end encryption
• OpenAPI design with real-time preview
• Mock servers built from collections or specs
• Inso CLI for validating specs and running tests in CI/CD

Pricing

• Essentials: $0 per user; unlimited cloud and local projects; Git Sync for up to 3 users; 1,000 mock server requests per month
• Pro: listed at $12 per user per month; unlimited users with Git Sync; 10,000 mock requests per month
• Enterprise: listed at $45 per user per month, self-serve up to 50 users; unlimited mock requests, storage controls, SSO (SAML/OIDC) and SCIM

Insomnia advertises up to 17% off for annual billing. Extra mock requests are $10 per 25,000.

Pros

• The closest overall match to Postman, so migration is straightforward
• You decide where each project lives: local only, your Git repo or Kong's cloud
• Strong protocol coverage including gRPC and MCP testing
• Enterprise can mandate where projects are stored, which helps security teams

Cons

• Account and storage rules have changed before (8.0 in 2023), so check current terms against your data policy
• Free Git Sync stops at three users
• Enterprise pricing is high per seat compared with Bruno or Hoppscotch

Who should use it

Teams that want a Postman-shaped tool with a real local and Git option, especially Kong Gateway users.

Who should skip it

Teams that want zero cloud features in the product at all. Bruno or Yaak are simpler there.

Bruno review

Bruno describes itself as an open source IDE for exploring and testing APIs. Its GitHub README states the core design choice plainly: "There are no plans to add cloud-sync to Bruno, ever." Collections are stored as plain text files on your machine, so you commit them to Git next to the code they test. It is MIT licensed and runs on macOS, Windows and Linux.

Key features

• File-based collections stored as plain text that diff cleanly in pull requests
• HTTP, REST, GraphQL and gRPC support in the free edition
• Scripting, tests and secret management in every tier
• Bruno CLI and Docker images for running collections in CI
• Git UI in the app (clone only on the free edition; more on paid tiers)

Pricing

• Open Source: $0; two workspaces; public Git providers; community support
• Pro: $6 per user per month billed annually; unlimited workspaces, private Git providers, 5 OpenAPI syncs per month, 48-hour support SLA
• Ultimate: $11 per user per month billed annually; secret manager integrations, data-driven testing, reports, audit logs, SSO/SCIM, unlimited OpenAPI syncs, 24-hour SLA

A 14-day Ultimate trial needs no credit card.

Pros

• Your API collections live in your repo, reviewed like any other code
• No vendor cloud to approve, since there is no cloud sync
• MIT license and a large open source community
• Paid tiers are cheap compared with Postman's Team plan

Cons

• No real-time collaboration; sharing happens through Git
• Private Git providers, data-driven tests and reports need paid tiers
• Fewer platform features (monitors, hosted mocks, catalog) than Postman

Who should use it

Developer teams that already review everything in Git and want API requests treated the same way.

Who should skip it

Teams with non-developers (QA analysts, support, partners) who need to browse and run requests without touching Git.

Hoppscotch review

Hoppscotch is an MIT-licensed open source API platform that started as a lightweight web app. Its GitHub README lists REST, GraphQL, WebSocket, SSE, Socket.IO and MQTT support, a web app at hoppscotch.io, a PWA with offline support, desktop apps for Windows, Linux and macOS, and a CLI.

Key features

• Browser-based client with nothing to install, plus desktop apps
• Broad realtime protocols: WebSocket, SSE, Socket.IO and MQTT
• Team workspaces with real-time collaboration on paid plans
• Self-hosting: a free Community Edition under the MIT license, or a self-hosted Enterprise Edition
• API documentation publishing and mocking on paid plans

Pricing

• Free: $0 forever; REST, GraphQL and realtime testing, personal workspace, collections, environments, scripts, runner
• Business (cloud): $6 per user per month billed annually; team workspaces, shared collections, published docs, mocking, admin dashboard
• Enterprise (cloud): $11 per user per month billed annually; RBAC, SAML SSO, OIDC, SCIM, audit logs
• Self-hosted Enterprise Edition: $19 per user per month billed monthly, per Hoppscotch's self-hosting docs

Pros

• Runs in a browser, so anyone can open it without an install
• Can be fully self-hosted for free under the MIT license
• Widest realtime protocol support in this list
• Low per-user price for team features

Cons

• Self-hosting the Community Edition means you run and update it yourself
• Fewer advanced testing and governance features than Postman
• Real-time collaboration and docs publishing need a paid plan or the self-hosted Enterprise Edition

Who should use it

Teams that want a shared, browser-based API client, and companies that must keep everything on their own servers.

Who should skip it

Teams that want collections stored as files in their code repository. Bruno or Yaak fit that better.

Thunder Client review

Thunder Client is a REST API client that runs inside VS Code (and, on paid plans, JetBrains IDEs). Its docs describe it as focused on "simplicity, clean design, and local storage." Requests are stored on your machine, and paid plans add Git Sync to save them in your repository.

Key features

• Runs inside VS Code, so you never leave the editor
• Local storage of requests and collections
• Scriptless tests set up through the GUI
• Git Sync for sharing collections through your repo (paid)
• CLI for running collections in CI/CD (paid)

Pricing

• Free: $0; VS Code only; 250 collection runs per user per month; no Git Sync, CLI, scripting or WebSocket/SSE/gRPC
• Starter: $3 per user per month billed annually; individual license; JetBrains support, Git Sync, CLI, custom scripting, 500 runs per month
• Business: $7 per user per month billed annually; unlimited runs, centralized billing, payment by invoice
• Enterprise: $16 per user per month billed annually; SSO, secrets manager integration, audit logs, offline activation

Thunder Client's current terms say the free version "may be used for personal or business purposes."

Pros

• No context switching for developers who work in VS Code
• Very low paid prices
• Local storage by default
• Git Sync and CLI on the cheapest paid plan

Cons

• The free plan leaves out Git Sync, CLI, scripting and non-HTTP protocols
• Not open source
• Tied to an editor, so less useful for QA or non-developers

Who should use it

Individual developers and small dev teams who test APIs while coding and want the cheapest paid option.

Who should skip it

Teams that need a standalone app for testers, or anyone wanting a strong free tier.

Yaak review

Yaak is a desktop API client built by Gregory Schier, who created Insomnia and sold it in 2019. It is open source under the MIT license and local-first: its pricing page says Yaak "does not store or sync your data," and that everything stays on your device unless you export or share it.

Key features

• HTTP, GraphQL, gRPC, WebSocket and SSE support
• Git-friendly storage: requests saved as individual YAML files, with a built-in Git UI for branching, committing and diffing
• Secrets encrypted with keys stored in the OS keychain
• Imports from Postman, Insomnia, Bruno, OpenAPI/Swagger and curl
• Plugins, a CLI and an MCP server plugin for AI coding assistants

Pricing

• Personal use: free
• Individual: $79 per year for one person using Yaak at work
• Individual Lifetime: $399 one time
• Business: $149 per user per year, with SSO, user provisioning and transferable licenses

Yaak counts any work-related use as commercial. If an annual license ends, you can keep using the last version released while it was active. There is a 30-day free trial with no credit card.

Pros

• Local-first with no vendor cloud involved
• Direct importer for Postman collections
• MIT licensed, with a clear and simple license model
• A lifetime option for people who dislike subscriptions

Cons

• Any work use requires a paid license, unlike Bruno's or Hoppscotch's free tiers
• No hosted collaboration, monitors or mocks
• Smaller ecosystem than Postman or Insomnia

Who should use it

Developers who want a desktop app that keeps data on their machine, and teams happy to share through Git.

Who should skip it

Teams that want a free tool for work, or need hosted features like monitoring.

Stoplight review

Stoplight is a different kind of Postman alternative. It is an API design and documentation platform, now owned by SmartBear, built around a design-first workflow: you write the OpenAPI spec, enforce style rules, mock it and publish docs before writing code. Its open source tools (Spectral for linting, Prism for mocking, Elements for docs) can also be used on their own.

Key features

• Visual, form-based editor for OpenAPI descriptions and JSON Schemas
• Custom style guides that run validation checks during design
• Automatic mock servers for testing designs with stakeholders
• Reusable components shared across APIs and updated in one place
• Git integration with GitHub, GitLab, Bitbucket and Azure

Pricing

• Free: one user, one project
• Basic: $44 per month billed annually ($56 monthly), first 3 users included, extra users $11 per month annually ($14 monthly)
• Startup: $113 per month billed annually ($147 monthly), first 8 users included
• Pro Team: $362 per month billed annually ($453 monthly), first 15 users included, extra users $22 per month annually ($27 monthly)
• Enterprise: custom pricing

Pros

• Best design-first tooling in this list
• Flat team pricing with users included can be cheaper than per-seat tools
• Open source Spectral and Prism can be used without paying
• Strong for publishing public or internal API docs

Cons

• Not a day-to-day request client in the way Postman is
• The free plan is limited to one user and one project
• Stoplight is now part of SmartBear's wider API portfolio, so check the product roadmap before committing

Who should use it

API platform teams that design specs first and need consistent docs and style rules.

Who should skip it

Developers who mainly need to send requests and run tests. Pair Stoplight with Bruno or Insomnia instead.

Head-to-Head Comparison

Local-first and Git workflows

Bruno and Yaak are local-first by design, with no vendor cloud at all. Insomnia lets you pick Local Vault or Git Sync per project. Thunder Client stores data locally and adds Git Sync on paid plans. Postman's Native Git is a real step, but it is desktop-only and paired with Postman Cloud for sharing. Hoppscotch's free option for keeping data in-house is self-hosting.

Collaboration

Postman, Insomnia (Cloud Sync) and Hoppscotch offer real-time shared workspaces. Bruno, Yaak and Thunder Client share through Git, which works well for developers and poorly for people who don't use Git.

Price for a 10-person team

On annual billing, list prices work out to roughly: Postman Team $190 per month, Bruno Pro $60, Hoppscotch Business $60, Thunder Client Business $70, Yaak Business about $124 ($1,490 per year), and Insomnia Pro about $120 at its listed price. Stoplight Startup is $113 per month for up to 8 users plus $11 for each extra user. Free options for a 10-person team: Bruno's open source edition, self-hosted Hoppscotch Community Edition, and Thunder Client's limited free tier.

Protocols

Hoppscotch has the widest realtime support (WebSocket, SSE, Socket.IO, MQTT). Insomnia and Yaak cover gRPC, WebSockets and SSE. Bruno's free edition covers HTTP, GraphQL and gRPC. Thunder Client puts WebSocket, SSE and gRPC behind its paid plans.

How to Choose: Decision Framework

Ask these questions

1. Can our API data live in a vendor cloud? If not, look at Bruno, Yaak, Insomnia Local Vault or self-hosted Hoppscotch.
2. Who needs access? Developers only: Git-based tools work. QA, support or partners: you want shared workspaces (Postman, Insomnia, Hoppscotch).
3. Do we use Postman features beyond the client? Monitors, Flows, governance and the catalog have no direct match in Bruno or Yaak.
4. What's our budget per seat? Postman Team is $19 per user per month annually. Most alternatives are $3 to $12.
5. Are we design-first? If the spec comes before code, add Stoplight to the shortlist.

Red flags

• Choosing a tool whose free tier doesn't allow your use (Yaak requires a license for any work use)
• Migrating to a Mac-only or unmaintained client
• Assuming a Git-based tool will work for non-developers on the team
• Forgetting usage limits: Postman AI credits, Insomnia mock requests, Thunder Client collection runs

What to check before switching

• Import one real Postman collection with environments and pre-request scripts, and see what breaks
• Run your collection from each tool's CLI in your CI pipeline
• Check how secrets are stored and whether they could end up in Git
• Confirm SSO and audit log needs against the right tier

The Verdict: Final Recommendations

1. Bruno for most developer teams: free, MIT licensed, and your collections live in your repo.
2. Insomnia for a like-for-like swap with local, Git and cloud storage options.
3. Hoppscotch for a browser-based client you can self-host for free.
4. Yaak for a private, local-first desktop app, if you budget for a work license.
5. Thunder Client for VS Code users who want the cheapest paid plan.
6. Stoplight for design-first teams, alongside a request client.
7. Postman if your team uses monitors, governance, Flows or the API catalog, where its price buys more than an API client.

Conclusion

The March 2026 plan change turned "is Postman worth it?" into a real budget question for small teams. If you only use Postman to send requests, organize collections and run tests, Bruno, Insomnia, Hoppscotch, Thunder Client and Yaak all cover that for less, and most keep your data on your machine or in your own Git repo. If you use Postman as a full API platform, nothing here replaces all of it, and staying may be the right call. Either way, import one real collection into your top two choices and run it in CI before you commit the whole team.
