Karate Labs

Founded 2016

Automate API, browser, and performance tests using a single unified syntax

Pricing model

Free Tier, Paid

You can use Karate Labs to automate testing across REST, GraphQL, SOAP, and gRPC APIs alongside browser user interfaces. It lets you write tests in a readable Gherkin-like syntax without boilerplate code. Teams can run functional tests, stand up local mocks, and execute load tests with Gatling without rewriting scenarios. An AI-assisted runtime called Karate Agent handles browser automation using display text rather than fragile CSS locators. Everything runs self-hosted in your CI pipelines without exposing sensitive test data to external cloud services.

What Karate Labs does

Send HTTP requests and validate response JSON payloadsSimulate user clicks and form submissions in web browsersSpin up local mock servers for dependent microservicesExecute performance tests with concurrent virtual usersVerify complex business logic rules against expected outcomesSelf-heal broken UI locators during test runsUnified syntax for API, UI, performance, and mock testingDisplay-text locators that prevent tests from breaking on UI updatesBuilt-in stateful and thread-safe API mock serversPerformance test reuse powered by Gatling integrationDeterministic verification of test assertions with no model hallucinationSelf-hosted runtime supporting local models via OllamaMCP integration for Claude Code and VS Code Copilot
