Simulations
Create service sims from OpenAPI specs: endpoints, replays, access control.
Simulation types
Simulation typesFour ways to run the same mock engine: app simulations in the browser, GitHub-deployed with a URL per branch, portable on your own machine, and codegen with real logic in the handlers.Atualizado em 30 de ago. de 2026App simulationsThe browser-built kind of simulation: compose your own specs, catalog APIs and static endpoints into one deployment with one URL, and iterate by editing in the app and deploying in seconds.Atualizado em 1 de set. de 2026Simulations from GitHubDeploy simulations straight from a repository: one workflow step, a URL per branch and pull request, no account needed for the first push, and every change reviewed like code.Atualizado em 3 de set. de 2026Portable simulationsRun the same mock engine on your own machine: one command over a spec, a folder or a package, with hot reload on every file change and nothing leaving your computer.Atualizado em 30 de ago. de 2026Codegen simulationsGenerate a typed Go server from your spec: every handler serves the generated mock until you take it over with real logic, and the spec never leaves your repository.Atualizado em 30 de ago. de 2026
Create & deploy
Create a simulationThe ways to start a simulation, what name, domain and slug mean, and when it starts serving.Atualizado em 1 de set. de 2026Start from the catalogBrowse the catalog of commonly requested provider APIs, see what each spec ships, and start a simulation from one in a click.Atualizado em 1 de set. de 2026Upload and update an OpenAPI specUpload an OpenAPI 3 spec in YAML or JSON, stay inside the size limit, tame large specs, and replace a spec without losing settings.Atualizado em 1 de set. de 2026Share linksShare a simulation with a link anyone can run locally, hand over a packaged file, or invite collaborators. No deploy needed.Atualizado em 1 de set. de 2026Run a simulation locallyRun any simulation on your own machine from its share link or a .mockz file, with the CLI, Docker, or Docker Compose.Atualizado em 1 de set. de 2026Deploy and URLsWhat a deploy does and where a simulation answers: the available domains, why first deploys take a minute and redeploys seconds, taking unused simulations offline, and the soft build limits.Atualizado em 30 de ago. de 2026

Endpoints and static responsesEndpoints in a Mockzilla simulation: how their URLs are built, and how to add static endpoints with fixed responses you can change and redeploy in seconds.Atualizado em 1 de set. de 2026Service settingsPer-service settings in a Mockzilla simulation: mount path, upstream proxying with mock fallback, response caching, request and response validation, and spec options.Atualizado em 1 de set. de 2026Access controlControl who can reach a Mockzilla simulation: an API key on the mock API, credentials or a full switch-off for the API explorer, an IP allowlist, and runtime environment variables.Atualizado em 1 de set. de 2026
Replays
Record and browse replaysRecord a response once and serve it back for every matching request: the X-Mockzilla-Replay header, match keys on body, query and path fields, auto-replay, and editing recordings in the app.Atualizado em 1 de set. de 2026Export and import replaysPack a service's recordings and replay settings into one portable file, and import it into any simulation: conflicts, size limits, and sharing a canonical fixture set with your team.Atualizado em 1 de set. de 2026
Observe & debug
Request historyEvery request a simulation answers is recorded: browse and filter the log, open full request and response details, mask sensitive headers, and set per-service retention.Atualizado em 1 de set. de 2026Usage and limitsWatch what your simulations serve and what your plan allows: request and data transfer usage, throughput throttling, simulation and ref caps, and topping up a busy month.Atualizado em 1 de set. de 2026
