About this product
Front-end work and integration tests stall when the real API is not ready. Fixture Freight is 150 mock APIs with believable, internally consistent data: shops, bookings, invoices, logistics, ticketing, HR, IoT readings and more, each with pagination, filtering, validation errors and optional latency injection.
Everything runs from a single Docker image with an OpenAPI document per API, so your client generators and contract tests work against it unchanged. Your fare unlocks domains in the listed order.
You choose the fare: anything from €1 to €100, in whole euros. At €100 you get every part, plus all future additions to it.

Her rule for a kit is simple: if she would not deploy it for a paying client, it does not ship.
