Epiq is an MIT-licensed, Git-native issue tracker that keeps the board as an append-only event log synced through Git and replays it on demand, built so unattended agent work becomes auditable history through an MCP server, a skill file, and per-agent identities. **Workflow replay is the audit interface unattended agent sprints need, and storing the board as an event log in Git is a storage choice no other member of this category makes.** ## What it is A self-hosted, local-first tracker running as a terminal UI (built with Ink) and a browser GUI over one event-sourced engine: every change is an append-only event in a per-user log file, and the board is materialized deterministically by replay, with ULIDs plus last-known-edge references ordering concurrent events across machines. State lives in a managed Git worktree outside your checkout (`~/.epiq-global/worktrees/`), project metadata in `.epiq/project.json`, so `:sync` over a git remote is the whole collaboration model, with no accounts, SaaS, or external services. Agents get three doors: an MCP server (`epiq-mcp`, thirty-odd tools) for deterministic access, an installable `SKILL.md` that teaches the recommended workflow, and per-agent identities, so each agent authors its own events, assigns itself, and shows up in the contributor list. Commits prefixed with a ticket's ref land in the ticket's inline code diff, where reviewers comment on lines, and the jolaflow identity maintains it under MIT. ## Status Active and shipping fast.

Star History Chart The Show HN launch thread reached 91 points and 48 comments on 2026-05-16, the second-largest HN footprint in this category after Backlog.md, followed by a 1-point video repost on 2026-08-30 and little independent coverage since, so current adoption rests on the repo's own curve. ## Strengths - Workflow replay is the audit interface unattended agents need: scrub the timeline to see what moved, who moved it, and the linked diffs, during the run or after it. - The event-sourced design gives multi-agent concurrency by construction: each agent writes its own log file, git merges stay trivial, and replays converge. - Per-agent identities turn the board into an attribution record instead of one shared user. - Ticket-to-commit ref linking with inline code diffs puts code review inside the ticket. ## Cautions - Conflicting updates to the same text block resolve last-event-wins with no character-level merge, a limitation the maintainer confirmed in the launch thread, recoverable only through time-travel peeks. - The launch thread's historical objection stands: distributed git issue trackers have repeatedly died on design problems of exactly this class, and Epiq is one maintainer's answer. - Global npm install drew the thread's loudest resistance, and the npx-based MCP startup resolves against the registry on every start, which hangs in network-restricted agent sandboxes unless you install globally and point at the binary. - The web UI arrived after launch and the project is single-maintainer at 538 stars, so bus risk and community footprint are both thin for a system of record. ## Pricing Free and open source under MIT. No paid tier, hosting, or account exists. ## Compared to - [beads](../beads/index.md): both are repo-local state layers with concurrency designs, Dolt atomic claims versus event-log replay; choose beads when agents need a dependency-ready work queue, Epiq when the audit trail is the product. - [Backlog.md](../backlog-md/index.md): both keep state in git, but Backlog.md's three review gates run before code exists while Epiq's replay runs after. - [It's a Plan](../its-a-plan/index.md): the platform counterpoint, a server board where agents hold assignee slots, versus Epiq's repo-local logs. ## Bottom line **Recommended for engineers running unattended agent sessions who need to reconstruct what happened, in the repo, without a server.** Not for text-heavy collaborative editing under concurrency (last-event-wins) or teams that need a non-developer PM interface. My disagreeable claim: the append-only event log is a better memory format for agent work than the markdown files this category keeps choosing, because replay answers "what happened" without inventing a schema for it. ## Changes - 2026-10-10 - Created after the broad-list and GitHub search scan surfaced the 91-point launch thread the category had not resolved. ## See also - [beads](../beads/index.md) - the other repo-local state layer, graph database versus event log - [Backlog.md](../backlog-md/index.md) - the markdown-native review-gate counterpoint - [It's a Plan](../its-a-plan/index.md) - the platform-style counterpoint where agents hold assignee slots - [Task Management Feature Matrix](../task-management-feature-matrix/index.md) - the category comparison this note joins ## References - https://github.com/ljtn/epiq - repository: README, MCP setup, agent identities, install paths (fetched 2026-10-10) - https://api.github.com/repos/ljtn/epiq - stars, forks, watchers, dates, MIT license as of 2026-10-10 - https://raw.githubusercontent.com/ljtn/epiq/main/readme.md - the event-sourced model, conflict handling, MCP and skill setup, worktree sync - https://ljtn.github.io/epiq/ - the site: teams-and-agents positioning, live monitoring and replay wording, the MCP tool count - https://news.ycombinator.com/item?id=48155570 - the 91-point launch thread: the distributed-tracker history objection, the last-event-wins exchange, the MCP-versus-skill debate - https://api.github.com/repos/ljtn/epiq/releases - v1.12.4 (2026-10-08) and the v1.12.x release train - https://api.npmjs.org/downloads/point/last-month/epiq - 2,825 downloads last month
