Why Blackbird?
While Postman has been a standard for API developers, Ambassador Blackbird is redefining the space with a developer-first, end-to-end API platform, and development environment that’s made with the future in mind. We’re not telling you to ditch Postman altogether, but your development lifecycle deserves a tool that supports the process from spec creation to deployment.
Blackbird is purpose-built for modern API development, offering seamless mocking, robust testing, and easy collaboration in a dedicated, hosted environment. Look, Postman is great for quickly interacting with your APIs, but eventually, you'll have to go outside of the platform to accomplish the rest of your development journey…that's where we can help.
Whether you’re ready to "break up" with Postman or not, check out how Blackbird stacks up.

Why Choose Blackbird?
Dedicated Testing Environments That Keep You in Flow
Unlike Postman, Blackbird handles the infrastructure, allowing developers to stay in their flow state (coding) for longer. Plus, with us managing the hosting costs, you don’t have to worry about environmental costs spinning out of control every month.
Faster Development with API Code Generation & Hosted Mocks
Blackbird automates API client and server code generation, helping developers move faster. Plus, it enables instant, hosted mocks, reducing dependencies and allowing teams to test APIs before building. On the other hand, Postman’s mocking capabilities are shareable, but parts do require manual setup. and local configurations.
Unlimited Purpose-Built API Development
Blackbird isn’t just for testing—it’s built for the entire API lifecycle, from design to deployment, all within a fully hosted environment at no extra cost. Unlike other platforms with restrictions on collections, requests, and collaborators, Blackbird lets you build without limits.
Kubernetes-Friendly for Seamless Integration
Postman fails to offer a deep integration into specific tech stacks or environments, such as those who are Kubernetes fans. Blackbird is a Kubernetes-friendly tool that easily integrates with your tech stack (including other Ambassador products, coming soon).
Easy for Beginners, Powerful for Experts
A common complaint about Postman is its level of complexity. Blackbird is designed to make API creation and editing as simple as a chat request (for real!), and we abstract away the infrastructure complexity so robust testing is not a stretch for anyone getting started.
