Create your mock server
Build Stateful, High-Performance Mock Servers in Minutes
Create reliable, production-like APIs for development, testing, CI pipelines, and customer demos. Beeceptor turns your API specifications and ideas into stateful mock servers. Upload OpenAPI/ Swagger GraphQL, gRPC, or SOAP definitions to get fully functional mock servers with realistic test data.

No Code Mocking
Set up mock servers instantly without writing code. Create behavior using matching rules and customize responses through an intuitive UI.
Request Inspection
View request payloads, headers, and details in real-time. Debug webhooks and callbacks effortlessly.
Contextual Dynamic Responses
Generate dynamic test data by reusing request payloads, headers, and query parameters. Build context-aware responses that adapt to inputs and accurately simulate real API behavior.
OpenAPI Import
Upload your OpenAPI (Swagger) spec and instantly get a fully populated mock server with AI-generated data.
Proxy & Record
Proxy requests to a live backend and record them. Switch to mock mode when the backend is down.
Delays & Timeouts
Simulate network latency, timeouts, and errors to test how your app handles failure scenarios.
CRUD Routes
Create GET, POST, PUT, PATCH, and DELETE routes for any JSON Rest API. Backed by a schema-less database, giving you the flexibility to store and retrieve objects.
Stateful Mock Servers
Simulate network latency, timeouts, and errors to test how your app handles failure scenarios.
Local Tunnel
Route third-party event payloads directly to your development machine on specific port. Skip the deployment cycles, and iterate faster.
