MimiQ360 is free to download and run for non-commercial purposes: personal projects, evaluation, study and open-source work. Using it commercially or inside an organisation requires a paid licence, and running it commercially without one is a breach of the licence terms.

The download is licensed to you. Redistributing, republishing, reselling or otherwise passing it on is not permitted, and neither is reverse engineering, decompiling or disassembling it.

I understand this build is licensed to me for non-commercial use only, that commercial or enterprise use requires a paid licence, and that I may not redistribute or reverse engineer it.

Email me occasionally about MimiQ360 releases and updates. You'll get the download either way.

We use these details to understand who’s running MimiQ360 and to send you this download. We don’t sell them or pass them on.

Releases

Version history

Every published release, newest first.

The first tagged release of MimiQ360. One JAR, Java 25, and a mock server that speaks HTTP, WebSocket, SSE, gRPC and GraphQL.

Mocking

Mock runtime over HTTP, WebSocket, SSE, gRPC and GraphQL, with templated responses, match rules, response variants, latency and fault injection.
Stateful flows written in MFL (the Mimiq Flow Language), backed by a virtual database.
Proxy and record against a live service, then promote recorded traffic to endpoints.
Per-API rate limiting that answers 429 with Retry-After and the X-RateLimit-* headers.
RFC 7807 problem responses across every endpoint.

Getting your APIs in

Import from OpenAPI 3, either a file or a live URL, with re-sync.
Import from HAR, Postman collections, cURL, WSDL/SOAP and CSV/JSON.

Command line and CI

CLI verbs: serve, push, pull, validate and reset.
Local dev mode with hot reload and no database to provision.
A GitHub composite action, a GitLab template, and @mimiq360/test-helpers for Jest, Vitest and Playwright.

Teams

Projects and RBAC, review and approval, change history and rollback.
Activity feed, in-app notifications, presence, and comments with @mentions.
Enterprise auth: OIDC, SAML 2.0 and SCIM 2.0, built against a real Keycloak.

Running it

Prometheus metrics, health probes, graceful shutdown and OpenTelemetry.
Structured JSON logging with correlation IDs; request-log retention and rollup.
Backup and restore guides.

Security

Secrets are encrypted at rest, with a test asserting the plaintext is absent from the stored column rather than assuming it.
SSRF protection on remote spec fetching: scheme allowlist, per-hop redirect revalidation, and every resolved address checked against loopback, private, link-local, CGNAT and reserved ranges.
Import endpoints now check permissions before resolving a project by slug.
/mock/** is unauthenticated only under `mimiq360 serve`. The JAR, the container image and the Helm chart all keep authentication on.

Before you run it

Java 25 is the only prerequisite.
First run with no configuration starts an embedded PostgreSQL and persists to ./data. Set MIMIQ360_DB_URL for production.
`mimiq360 serve` is local development mode: unauthenticated by design, and not for shared use.
Config format version 1 · MFL 1.0.
