What is Bruno?
Bruno is a fast, open-source, offline-first API client that has become a popular alternative to heavier tools like Postman. Its defining feature is that it stores your request collections as plain text files right in your project folder, so they live in your git repository alongside your code — versioned, diff-able, reviewable in pull requests, and shared with your team the same way you share code. For developers, having API requests version-controlled next to the code they test is exactly how it should work.
Because it is offline-first and open source, Bruno just works without an internet connection or an account wall for basic use, and you can trust it, inspect it, and avoid vendor lock-in. It covers everything most developers need — building and sending requests, organizing collections, managing environments and variables, writing tests, handling authentication, and working with REST, GraphQL and more — while staying light and snappy. It opens instantly and stays responsive, a daily relief compared with the weight and cloud-lock-in that frustrate many Postman users.
Bruno suits individual developers and teams who collaborate through git and value speed, privacy and open source. It can import existing Postman collections, so trying it costs almost nothing. While large enterprises may still want Postman's deepest collaboration and lifecycle features, for everyday API testing Bruno is simply a nicer, lighter, more private experience. If Postman's growing weight, cloud lock-in or account requirements have been bugging you, Bruno is the git-friendly, offline, open-source client worth switching to.
What is Postman?
Postman is the world's most widely used API development platform — the place millions of developers design, build, test and document their APIs. What began as a simple tool for sending API requests has grown into a complete platform for the entire API lifecycle, now with AI agents built directly into the workflow.
What Postman is
Postman gives teams one environment to work with APIs end to end: designing specifications, building and mocking endpoints, testing them manually or automatically, monitoring them in production, and cataloging them for discovery. Collaborative workspaces keep everyone working from the same source of truth, so an API's design, tests and docs stay in sync as it evolves.
Who it's for
Postman serves software engineers and development teams, enterprises managing APIs at scale, and API-first organizations — used by the likes of Microsoft, Meta, Salesforce, AWS, Stripe and Uber. Whether you're a solo developer poking at an endpoint or a large company governing thousands of internal APIs, it scales to fit.
What it offers
- API Client for sending and inspecting requests
- Spec Hub and Workspaces for collaborative API design
- Mock Servers to test without a live backend
- Collection Runner, performance and data-driven testing
- Monitors for continuous API surveillance
- API Catalog and governance for discovery at scale
- SDK Generator and Postman CLI
- AI Engineer agent and MCP Server integration
The whole API lifecycle in one place
Postman's core strength is covering everything an API needs from one platform. Instead of designing a spec in one tool, testing in another and documenting in a third, teams do it all in Postman — with the pieces connected. That unified lifecycle means less context-switching and fewer things falling out of sync, which is exactly why it became the default tool for so many engineering teams.
Testing that catches problems early
Postman makes API testing accessible and thorough. You can fire off a single request in the API Client, run whole collections of tests in batches, load-test for performance, and set up Monitors that continuously watch your APIs and alert you when something breaks. Catching a broken endpoint before your customers do — automatically, around the clock — is a huge part of Postman's value for teams shipping real software.
Built for governance at scale
For enterprises, the challenge isn't one API but hundreds, and Postman addresses that with an API Catalog for discovery, application inventory tracking, and a Context Graph showing how services relate. That governance layer helps large organizations avoid duplicate work, understand their API landscape, and keep quality consistent — turning a sprawling mess of internal services into something discoverable and manageable.
An AI-native API platform
Postman has leaned hard into AI, positioning itself as AI-native rather than bolting AI on as an afterthought. Its AI Engineer agent can help build and test APIs, Agent Mode automates API workflows, and MCP Server integration lets AI tools use API context directly. As development increasingly involves AI agents, having them work natively with your APIs inside Postman is a genuine forward step.
Why choose Postman
For developers and teams building or consuming APIs, Postman is the established, comprehensive choice. Its coverage of the full API lifecycle, powerful testing and monitoring, enterprise governance and AI-native design — backed by a freemium model and adoption at the biggest tech companies — make it a practical platform for shipping reliable APIs, whether you're testing a single endpoint or governing an entire organization's services.
