Blocked by APIs?
Mock them. Keep shipping.
Unavailable, unstable, or unfinished APIs slow down development and break momentum.
Beeceptor lets you generate mock APIs instantly from OpenAPI, GraphQL, or gRPC specs using AI. Get realistic test data, inspect HTTP traffic, control responses, and keep shipping without waiting on backend services.
Specs to mocks
Import OpenAPI, GraphQL, gRPC, or WSDL specs and generate fully functional mock APIs instantly.
Learn MoreHTTP proxy
Inspect live API traffic, capture real responses, and debug integrations in real time.
Learn MoreLocal tunnels
Expose local services securely to test webhooks and external callbacks.
Learn MoreAI-powered test data
Automatically generate realistic, production-like responses that behave the way real APIs do.
Learn MoreYou do contract-first.
Now activate those contracts.
Parallel Development
Faster Feedback

with API Mock Server, Local Tunnel and HTTP Proxy toolset.
Build Without Waiting on APIs
Develop, test, and ship even when backend or third-party APIs are unavailable, unstable, or incomplete.
Frontend teams waiting on backend readiness
Unstable or unavailable third-party APIs
Vendor delays sharing integration contracts
Authentication and token setup blocking local dev
Rate limits breaking tests and CI runs
CORS issues slowing frontend development
Expensive third-party APIs used in test environments
Inconsistent test data and response formats
Webhooks requiring frequent deployments to test
No safe way to test webhook retries and failures
DevOps delays provisioning test services
High API costs during load and performance testing
Poor test coverage due to external dependencies
Legacy systems that cannot support modern testing
