Keploy for developers

simplified testing, capturing network interactions and generating automated tests

Give your teams the tool they need to move faster

Accelerate development with streamlined testing, capturing network calls, automating scenarios, and seamless tool integration.

Record Replay API Flows

Record and replay complex, distributed API flows as mocks and stubs. It's like time machine for tests!

Find Duplicate Tests

Find redundant tests that doesn't add to the test coverage. Automatically detect and remove duplicate tests, ideal for big-teams crowd-sourcing tests.

Works with JUnit, PyTest, Jest, Go-Test in CI/CD

Merge Keploy tests coverage with unit testing libraries for combined test coverage gating in CI/CD pipelines like Jenkins, Github Actions.

Getting Started

Start Recording Test cases with code-less integration

1. Installing 📥

Integrate Keploy by installing the open-source agent locally. No code-changes required.

curl --silent -O -L https://keploy.io/install.sh && source install.sh

2. Record 🎬

Start your app with keploy to convert API calls as tests and mocks/stubs. Make some API calls to your app.

keploy record -c CMD_TO_RUN_APP

CMD_TO_RUN_APP is the command to start you app. Say,python main.py or npm start or java -jar xyz.jar orgo run main.go

3. Test 🧪

Shut down Database , Redis , Kafka and other services. Keploy don't need those during test.

keploy test -c CMD_TO_RUN_APP --delay 10

"We've had a great experience with Keploy—it's significantly improved our testing process. Using it for our Golang projects with Postgres and Redis, Keploy helps us quickly identify and fix issues by replaying real user interactions. This has saved us time and enhanced our test thoroughness. We're pleased with the results."

"Makes it easy to unit test my complex systems with realistic test data."

Staff Engineer / @Nutanix

Replicate data from any source

...in your language

Test smart - Build better

❌ Just say no to ❌

Blind network calls

Unseen network calls hinder testing and analysis of software behavior.

Manual test writing

Time-consuming, repetitive to maintain test automation suites.

Inefficient codepath

Underperforming code leading to critical problems and inefficiencies.

Dependency chaos

Tedious stubs and mocks maintenance for testing purpose.

Mystery production issues

Difficult-to-reproduce production issues locally for testing and debugging.

Scattered test environments

Multiple env complicates testing, stub preparation and are unrealistic.

We love when users talk about Keploy..

I tried keploy, it was amazing. Just wrap and start docker, and then just hit the API with curl or the client and you'll be able to test more and more. This is the golden test.

Why do I like keploy so much? Literally I see many tools and so hard to integrate. I mean update VScode , use the sdk , make this change make that change. With Keploy, don't worry buddy just run your application, we will literally do everything for you. You need to 0 efforts.

It is quite easy to create normal tests. On the other hand, abnormal systems may be a little difficult. I think it's okay to use it only for normal systems.

Based on the communication trace information that can be obtained using eBPF, it is possible to generate a test and a stub server to be used when executing the test.

I tried Keploy, good tool.

The point being, maintaining unit tests is terribly difficult, and in general requires more efforts than the actual development itself. I've hardly seen any startups even at good scale able to manage unit tests. If you really think it's a requirement you can try tools like Keploy. But I feel even if you honestly think, manual testing should be always feasible

Keploy test coverage Challenge!

How it works?

- Share Your Application Dependencies with us!

- Choose any backend application with the LOWEST Test Coverage!

- Our team will determine if Keploy can generate your API tests.
If we can!! you can keep the tests. If we can’t, you get $100.
