Postman covers more of the API lifecycle than any other client on this page. Its desktop app runs on Windows, macOS and Linux, a web app runs in the browser, and the client speaks HTTP, GraphQL, gRPC, WebSocket, Socket.IO and MQTT. The Free plan keeps an unlimited Collection Runner, 1,000 monitoring requests a month and 25 Flow credits, and the paid plans start at 9 dollars a month billed annually for Solo, or 12 dollars billed monthly. Postman says it is used by more than 50 million developers, so a collection shared with a partner or a vendor usually opens without a conversion step.
The reasons to switch are specific. Since March 1, 2026, the Free plan is limited to one user and cannot create a team, where it used to allow teams of up to three: a small team now pays for Team, at 19 dollars per user a month billed annually or 23 dollars billed monthly. Scratch Pad, the offline mode, was removed in Postman v10.18, and the lightweight client that replaced it works signed out but keeps collections and environments inside an account workspace. Developers who want requests versioned next to their code, reviewed in pull requests and never synced to a vendor cloud move to clients that store plain files on disk, such as Yaak, Kreya, Voiden or the open source Bruno, which is not listed on Uneed.
The alternatives on this page are API clients listed on Uneed. We compared each one with Postman in October 2026 on its official website, pricing page and documentation, on the five criteria of the table, which are the entry paid price as the vendor states it, what can be used for free, supported platforms, where collections are stored and gRPC support. We did not run benchmarks or test the clients side by side. Prices are in US dollars and billed monthly unless the table says otherwise.
Here are the best alternatives to Postman, ranked by popularity and user engagement.

Requestly is a modern, lightweight, open-source API client designed for developers who want more control, privacy, and flexibility in their workflows. Unlike traditional API tools that rely heavily on cloud storage, Requestly is built with a local-first approach, ensuring that your API data and collections remain securely on your own machine. This makes it ideal for developers who prioritize privacy and offline access. Requestly also introduces Git-based collaboration, allowing teams to version, branch, and manage API collections just like code. With built-in AI capabilities, the platform helps speed up API testing workflows and improve productivity. It supports REST and GraphQL APIs, environment variables, pre- and post-request scripting, and collection runners. Developers can collaborate easily with shared workspaces and migrate from other tools like Postman in just one click. Trusted by over 300,000 developers across leading companies, Requestly is built to streamline API development while maintaining simplicity and performance.
Kreya is a GUI client for gRPC, REST and WebSocket APIs (think Postman or Insomnia). Thanks to its unique features, Kreya makes building and testing APIs faster. Designed to be easy to use while also supporting advanced use cases. Kreya stores all data locally in a JSON format, giving the user full control over it. Local first, built with privacy in mind.
Somewhere along the way, API tooling lost the plot.
One tool for specs. Another for tests. A third for docs. Then a parade of SDKs, mocks, CI scripts, and shiny portals nobody asked for...
We got fed up, and from that frustration, Voiden was born.
Voiden keeps your specs, tests, and docs in one place. Use Markdown. Collaborate and version with Git. Extend with your own plugins. No account. No lock-in. No syncing, tabbing, or jumping between tools.
API testing tools are usually desktop-first, even though development often spans multiple devices.
HTTPBot is a native REST API client built specifically for Apple platforms, with support for common workflows like collections, environments, and request inspection.
NativeRest is for developers and teams seeking a superior API client. If you're tired of slow, resource-heavy tools and want a lightning-fast, intuitive, and secure solution with seamless collaboration across macOS, Windows, and Linux, NativeRest is built for you. Boost your productivity now!
RestRuno is a desktop REST API client designed for developers who want full control over their work. Collections are stored as plain JSON files on disk, ensuring your data stays local and portable.
Key features include:
Collections and environments for organizing API requests
Scripting capabilities for automation
Data-driven runner for batch testing
No vendor lock-in with file-based storage
Ideal for developers building, testing, and documenting REST APIs locally.
Stay on Postman if your team uses its mocks, monitors and Flows, or exchanges collections with partners who live in it. Move to Insomnia if you want the closest replacement and a free plan that still covers three people through Git Sync. Choose Hoppscotch if you want a free client in the browser or on your own server. Choose Yaak or Kreya if requests should be files reviewed in pull requests, Kreya first for gRPC work, and HTTPBot if you test APIs from an iPhone or iPad.
Hoppscotch is the best free option for most people, with a free forever plan, a browser version and a self-hostable Community Edition under the MIT license. Voiden is entirely free, with no paid tier, if you want Markdown files in Git. Insomnia's free Essentials plan suits a small team, since it includes Git Sync for up to 3 users.
Insomnia and Hoppscotch are the most established alternatives here. Insomnia is maintained by Kong and has around 40,000 stars on GitHub, Hoppscotch has around 80,000. Both have been around for years and both import Postman collections.
We've curated 9 alternatives to Postman on Uneed. Each alternative has been carefully selected based on features, popularity, and user feedback.
Pick Insomnia if you want the same kind of tool with local, Git or cloud storage per project. Pick Hoppscotch if you want to work in a browser or self-host. Pick Yaak or Kreya if your collections should be files in Git, Kreya first if you test gRPC services. Pick HTTPBot if you work on an iPhone, iPad or Mac.
Yes, all nine clients on this page list Postman import. Insomnia imports Postman v2.0 and v2.1 collections, while Hoppscotch, Yaak and NativeRest also bring environments across. Scripts written for Postman's pm object may need rewriting, since each client has its own scripting API.
Yes, but for one person. Since March 1, 2026, the Free plan is limited to one user and cannot create a team, while keeping an unlimited Collection Runner and 1,000 monitoring requests a month. Sharing a workspace with teammates requires Team, at 19 dollars per user a month billed annually.
Yaak and Voiden need no account and store everything on disk, and RestRuno's free client works the same way. Insomnia offers a local-only Scratch Pad that is free forever. Kreya only asks for an account to verify a paid license.
Several. Hoppscotch is MIT licensed and self-hostable, Insomnia is Apache 2.0, Voiden is Apache 2.0 and Requestly is AGPLv3. Yaak publishes its source under MIT, but a license is required to use its builds at work. Bruno, a Git-based client not listed on Uneed, is also MIT licensed.
