Create chaos.

API mocking in Blackbird can be tested under Chaos mode to simulate real-world scenarios with error responses and controlled latency. Improve error handling and improve performance seamlessly from design to delivery.

Why teams love Blackbird

Blackbird's actually great, when you have a complex workflow in a dashboard SPA that involves multiple steps, finalized with payment, that ca fail due to connectivity, simulation of error like packet drops or session expiration is highly valuable during aggressive automated testing.

Principal SRE & Infra Architect

We choose to use Blackbird since it allows us to build the API in the shortest amount of time possible while also producing a killer API.

The Humorie Team

While creating tests in Python, we had to create some scenarios of each endpoint. We fixed some bugs in the code but it did take longer time to debug with various test cases when compared with Blackbird setup.

The GroceryGuardian Team

We need to give this huge lift of productivity to each and everyone. With a solution like Blackbird, plus what we are already doing, will help people to adapt their skills and be more innovative … that’s the holy grail.

Blackbird makes things very easy to use. Without proper API specs, nothing works well, that's what you need in a tool.
