} Generates fictional, vendor-neutral deployment fixtures for release dashboards, CI/CD demos and incident tests. Services, commit hashes, artifact digests and registry references are synthetic; the reserved registry.example.test host cannot identify or mutate a real registry.
Lifecycle states are exact. Queued has no start or finish. Running has started but not finished. Succeeded, failed and cancelled have an exact positive duration. A rolled-back deployment first completes its primary rollout, then restores a different commit and artifact in the same environment; rollback timestamps are later and its own duration is exact. finishedAt and durationSeconds describe the primary rollout, while the nested rollback and timeline expose the later restoration.
The root route returns current snapshots. /timelines returns the corresponding ordered event stream. With identical params, seed and count, record N in both routes represents the same deployment, making it practical to test snapshot/event projections against one fixture source. from and to constrain initiation only and are capped at 366 days.
Yes. Queued has neither start nor finish, running has only a start, and every terminal rollout has an exact positive finishedAt - startedAt duration.
The primary rollout succeeded first, then a later same-environment rollback restored a different synthetic commit and matching artifact reference.
Yes. Use the same params, seed and count on / and /timelines; corresponding records share deployment ID, service, environment and final status.
Fake git commits — Conventional Commits or plain messages, 40-char hashes, safe author emails, dates in your range and realistic diff stats. Fully seedable.
Generate coherent fake audit records for authentication, CRUD and permission changes — safely seeded, filterable and bounded by time.
Realistic job postings with level-coherent USD salary ranges — filter by level, department, employment type and remote, and every filter truly works.
Developer-productivity task fixtures with working status, priority, assignment, due-date and tag filters plus coherent subtasks and blockers.
