Contract Driven Development

Collaboratively Design and Independently Deploy MicroServices & MicroFrontends

Contract Testing - Turn your contracts into executable specifications

Executable Qontract Spec
Semantic Contracts

Drive cross-functional team conversations.

API-First

Language agnostic contracts used by interdependent teams using different tech stacks.

Collaborate

Jointly agree on the API design first by fleshing out the contract. This executable contract will capture various scenarios handled by the API and can be the single-source-of-truth.

Run as Test

Get started without writing any additional code. Language agnostic, auto-generated test data.

Run as Stub

Ensure coherence between providers and consumers.

Seamlessly Integrate

A sure-shot way to avoid integration hell. As long as the provider and consumer adhere to the contract, each of them can confidently develop and deploy independently.

Backward compatibility Verification

Easy Sync between versions.

Tight CI Integration

Automate. Shift-Left to catch errors earlier.

Mistake-Proof Changes

Just run the new version of the contract with the previous version to verify backward compatibility. Foolproof your integration by executing compatibility checks as part of your CI pipelines.

One Qontract to rule them all

Tagline

Contract First

With an API-first approach, you can use Consumer or Provider driven contracts, whatever suits your needs the best

Human Readable Contracts

Qontract leverages Gherkin’s strength as a specification mechanism to define your services. No additional language specific tooling required

Backward Compatibility Verification

Contract vs Contract testing (cross version compatibility checks) etc.

Service Virtualisation

Run your contract in stub mode and isolate yourself from downstream dependencies (also be sure that your stubs are 100% compatible with the actual provider)

Contract as Test

Test drive your services (APIs) using a contract

Tight Integration with CI

Trigger Provider and Consumer CI builds when any of the contracts change

Multiple Protocols

Supports REST, SOAP, Kafka

Import your APIs

Use Postman Collections or Qontract's http proxy

Platform Independent

Use the command line to integrate with any programmatic environment
