API Test Base features

  • Multi-protocol support. Test APIs over HTTP, SOAP, databases, JMS, MQ, AMQP, MQTT, FTP/SFTP, files and more.
  • No-code/low-code UI. Create test cases with a visual editor and store them as YAML.
  • Automated test setup. Define data seeding, cleanup and stub databases inside each test.
  • Data-driven testing. Run the same test with multiple input values.
  • Docker integration. Run tests against throwaway containers for isolation.
  • Git-based collaboration. Keep test files in version control and share across teams.
  • Offline-first. All data stored locally; no account or cloud required.
  • HTTP stubs. Mock external services within tests.

WunderGraph features

  • Connect any service. Expose gRPC, Kafka, NATS or Redis services through a unified GraphQL router without extra infrastructure.
  • Real-time streams. Router handles subscriptions, aggregating events from Kafka, NATS or Redis and pushes updates to clients.
  • MCP Gateway. One gateway turns approved operations into agent-ready tools with built-in authentication, eliminating separate MCP servers.
  • Graph governance hub. Shared canvas for schema design, review, ownership, proposals and safe deployments with audit logs and RBAC.
  • Cache warming. Pre-warm query planning cache to eliminate long planning delays for high-load scenarios.
