About Testfly
We are building the mock API platform we always wished existed.
Our Mission
"Mock APIs should have real data, real relationships, and real CRUD — not static JSON files."
Frontend developers waste hours waiting for backend APIs. QA teams struggle with inconsistent test data. Prototypers hack together fake servers that break at the first integration. We built Testfly to fix all of that — upload an OpenAPI spec and get a fully functional mock API with relationally-consistent data, in seconds.
Our Values
What we stand for
Simplicity
Upload a spec, get a working API. No SDKs, no configuration files, no deployment scripts. We obsess over removing friction.
Data Integrity
Mock data should behave like production data. Every foreign key resolves. Every relationship holds. If the mock lies, the tests lie too.
Developer Experience
We are developers building for developers. Every API response, every dashboard interaction, every config option is designed to feel natural and obvious.
