Beeceptor - mock api serverBeeceptor Features & Use Cases

Discover how Beeceptor can streamline your development workflow, speed up API integrations and software delivery. Explore the range of use cases Beeceptor can solve for you below!

Replace Dependencies With Mocks

Host your API contracts on Beeceptor and unblock your teams. With Beeceptor, a mock API server is up and running in seconds – no coding required.

Create A Mock API Server

Start API Integration Without Delay!

Don't wait for backend APIs to be developed or deployed. Connect to an API mock server and start integrating your code immediately. Reduce dependency on backend/API teams with Beeceptor.

Create A Mock API Server

Public HTTP Endpoint

Get a named sub-domain and send an HTTP request.

You can inspect and debug the req/res payloads, make it look pretty it and share with your peers as API contracts.HTTP Request Details

Stateful CRUD APIs

Define an entity path and let Beeceptor automatically set up six essential JSON REST APIs for your CRUD operations. This JSONPlaceholder alternative has a flexible schema, storage and super easy setup.

Create CRUD APIs

Partial Mocks - Mock or Forward

You can wrap an existing API domain to enable proxy mode and selectively mock specific routes, ensuring seamless integration and productivity.

It's like patching unavailable APIs on an existing API server, helping you integrate faster.

Bring Your OpenAPI Spec!

Beeceptor takes your OpenAPI Specification to next level by hosting a mock server with just one click. You can upload the specification file to an endpoint and start serving requests.

Upload an OAS spec

localhost:8080 ==> {public URL}

Beeceptor's local tunnel gives your APIs a secure and public URL, directing all incoming traffic to a designated localhost port. Use this to demos apps directly from localhost, and share applications over the internet.

Local Tunnel

Webhook Integration

Get a public HTTPS endpoint for webhook payload discovery. Expose your localhost services to a public URL to route third-party event payloads directly to your local development machine. Skip the deployment cycle and build faster with Beeceptor.

Create An HTTP Bin

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

HTTP Request Monitoring

Monitor HTTP requests and responses in real time. Beeceptor acts as an HTTP logger to help you spot failed API calls and errors in payloads, with logs kept searchable for up to 10 days.

Request History

Simulate Latencies & Timeouts

Simulate higher latencies by introducing delays and timeouts to the mocking rules. Helps you validate rarely reachable code paths.

No More CORS Headaches!

Beeceptor supports CORS out of the box. By default, all origins are accepted, allowing you to instantly unblock frontend teams. You can also specify and grant access to particular origins for testing purposes.

Access-Control-Allow-Origin: https://your-domain.com

Simulate Rate Limits

Configure your endpoint to mimic rate limits, setting maximum requests per second, minute, or hour. This is essential when developing queue consumers or integrating 3rd party APIs requiring retry mechanisms.

Rate Limits

Simulate Third-Party Services

Flaky third-party sandboxes and unavailable APIs can destabilize your integration suite. With Beeceptor, you can accelerate your releases by easily mocking the APIs you depend on, ensuring integration suite stability and improving overall reliability.

Free Sample JSON APIs

Mock Server + Local Tunnel + HTTP Proxy

Transform API development and integration with this all-in-one toolset.

Discover how Beeceptor empowers your development workflow with API Mock Server, Local Tunnel and HTTP Proxy toolset.

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.
Trusted by thousands of developers and QA engineers across the globe eliminating API bottlenecks everyday!

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.

A fantastic tool for semi-live data!

Having Beeceptor as a man-in-the-middle between your app and its api is a fantastic tool for working with semi-live data where logging or throwing bogus responses into the datastream is condition you want to test.

For the cost, I am impressed with the features provided!

It has been relatively easy to implement within my team, with the ability to create new mocking rules directly via the request logs.
