Bring a spec or create your own to mock

Popular API specs
Choose from specs like OpenAI, Slack, Zoom, and Twitter (X) to get started.
BYO API specs
Easily upload your existing API spec into Blackbird to mock.
Create new APIs
Describe the API you need in the chat and let Blackbird build it for you.
Instant APIs for AI
It’s as simple as a click of the button to get OpenAI’s API specification up in your hosted Blackbird environment. Launch a mock and share the URL with stakeholders or use the mock as a dependency to build and test other APIs.

Propel Parallel Development
Boost project speed and efficacy with smooth API spec generation and advanced mocks. Enable real-time collaboration between front-end and back-end teams.

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.
Driss Lamrani, CEO A2IM Robot Advisors
Blackbird makes things very easy to use. Without proper API specs, nothing works well, that's what you need in a tool
