Free mock rest API creator onlineCapture HTTP traffic, create rule, inspect response, webhook development. Free alternative to requestbin and mockbin server to build dummy apis.

Build mock APIs in a few seconds

No downloads, No dependencies.

Create a mock server and start building...
A sub-domain will be created for this endpoint where you can send requests.
collaboration between teams

Break barriers, not your momentum!

Reduce Dependencies and increase developer productivity by deploying mock API contracts. All you need is to create an endpoint, define mocking rules and send mocked responses. Copy the endpoint URL and start sending requests.

It's that simple!

Customer Testimonials

Fastest Mock REST API I have ever done. After getting sick of installing and configuring local tools or struggling with cloud servers to get some dummy APIs up so I can see what my app sends and manipulate the response... Beeceptor made that 2min task!

Ease of use is the main thing about it. It's also quite flexible too. I've been using it to mock integrators that are being developed in parallel to my app and having Beeceptor as a fake integrator has helped me to catch bugs early on.

Beeceptor Use Cases

Beeceptor solves versatile range of use cases tailored to enhance your development workflow and enabling you to expedite API integrations and software delivery!

Inspect HTTP Traffic
Get a named sub-domain and send an HTTP request. You can inspect the request payload and headers here, pretty-format the payloads and share with your peers.
HTTP Request Details
Build A Mock API
Using Beeceptor, a mock API endpoints is up and ready to be consumed in a few seconds - No Coding Required. Just define API path, matching rule and response payload.
How to setup mock routes
Proxy Mode - Mock or Forward
Wrap an existing API domain with a Beeceptor endpoint to enable proxy mode. Intercept all the traffic going to the original API. Additionally, you can use mocking rules to mock a few requests and forward the rest to target API.
Reverse Proxy & Intercept
Bring Your OAS Spec!
Beeceptor takes your OpenAPI Specification to next level by hosting a mock server with just one click. You can now upload the specification file to an endpoint and start serving requests.
Upload an OAS spec
Dynamic Mocked Response
Customize the response of your mock API by selecting the appropriate request payload and query parameters that fit your specific requirements.
Using Templates Variables
Simulate latencies & timeouts
Simulate higher latencies by introducing delays and timeouts to the mocking rules. Helps you validate rarely reachable code paths.
CORS Support (preflight requests)
Beeceptor, comes with CORS support and all origins are accepted out of the box.

Access-Control-Allow-Origin: *
OPTIONS calls will get '200 OK' always.
Named sub-domains and HTTPs!
Get named endpoints/sub-domains - easy to replace base URL in your code. All endpoints are HTTPs enabled (free or paid).
Request Logging
Search and review all the captured requests and responses. You can filter these by the response-code or request-path to drill down. The requests are available and searchable for 10 days.
Request History

Go beyond traditional API mocks...

  • Beeceptor is a no code solution for building and hosting a mock server.
  • Beeceptor gives you a dashboard to intercept and inspect all HTTP requests in real time.
  • Simulate higher latencies by introducing delays and timeouts. This helps you validate rarely reachable code paths.
  • Use reverse proxy to quickly switch APIs endpoints. E.g. A/B testing by switching API endpoints or versions without any redeployment.
  • Send hyper-customized responses using Handlebar template.
  • When load testing your API, do you really need to pass on the load to downstream APIs? Let Beeceptor mock it for you.
  • Don't block your UI developers when backend APIs are still in development. Just mock it!
  • Create webhook endpoints and capture all the incoming requests. Additionally, setup free local tunnels for development.
  • Share a request and response with peers using unique links.
  • All endpoints support HTTP, HTTPS and HTTP/2.
