Features
Everything Mockzilla offers to make API simulation effortless for your team.
Spec-Driven Simulation
Your OpenAPI spec is the single source of truth. Mockzilla reads it and generates a simulation server that returns valid responses matching every schema, status code, and content type defined in your spec.
Portable Mode
The simplest way to get started. Pack your OpenAPI specs into your repo, add the GitHub Action, and push. Mockzilla handles the rest. No code, no compilation, no custom logic needed.
Codegen Mode
For teams that need custom logic. Mockzilla generates typed Go handlers from your spec. Add your business logic, compile, and upload the binary. Full control over every response.
PR Environments
Every pull request automatically gets its own simulation URL. Test API integrations in CI before merging. URLs are cleaned up when PRs close.
Multi-Region Deployment
Simulations deploy to 24 regions worldwide. Your simulation runs close to your team for the lowest possible latency.
Rate Limit Headers
Every response includes X-Mockzilla-RateLimit headers showing your usage and remaining quota. Build rate-limit handling into your integration tests.
API Key Authentication
Optionally protect your simulation with an API key. Every request must include the X-Mockzilla-Api-Key header. Keys are hashed and never stored in plain text.
GitHub Action Integration
A single GitHub Action handles everything: packaging specs, uploading, provisioning, and status polling. Works with any GitHub Actions workflow.
