# Zit > Zit: a git extension for many developers and coding agents changing one repository at once. ## Get started - [Zit](https://getzit.org/): A git extension for many developers and coding agents changing one repository at the same time. Copy-on-write workspaces instead of worktrees, changes checked against what landed meanwhile, and each change's reason kept. - [Zit 101](https://getzit.org/tutorial): Install Zit, add it to a repository, make a change by hand, accept a teammate's branch and an agent's work, and publish to git. - [Quickstart](https://getzit.org/quickstart): From a git repository to three concurrent changes, one of them stale, all resolved. - [What Zit is, and is not](https://getzit.org/why): The problem Zit solves, the problems it does not, and how much disk and time it saves, with the measurements behind each answer. - [Compared](https://getzit.org/compare): Zit next to Zed's Delta (DeltaDB), Entire, GitHub merge queue, GitLab merge trains, Graphite, Conductor, Claude Code worktrees, Cursor worktrees and plain git worktrees, from each tool's own documentation. ## Use it - [Agents](https://getzit.org/agents): Run Autohand Code, Claude Code, Codex, Pi or any other agent CLI against the graph, by wrapping the process or over MCP. - [Web view](https://getzit.org/web): A live picture of the repository's changes in the browser, started from the CLI. - [Working with git](https://getzit.org/git): Zit lives inside a git repository, reads any commit as a change, and publishes by moving a branch. ## How it works - [Concepts](https://getzit.org/concepts): The six primitives and how each one is stored. - [How it works](https://getzit.org/science): The ideas Zit is built from, where each comes from, and how each is implemented. - [Research](https://getzit.org/research): What is measured about coding agents, parallel sessions, change volume and merge conflicts, with sources, and what it is not evidence for. - [Prior art and objections](https://getzit.org/prior-art): Research and tools that tackle concurrent changes to one codebase, the strongest objections to Zit's approach with the evidence on each side, and where Zit is weak. ## Evidence - [Benchmarks](https://getzit.org/benchmarks): Zit measured against git worktrees, on one machine, including where it is slower. - [Lessons](https://getzit.org/lessons): What broke when real agents and developers used Zit on real repositories, and what changed because of it. - [Limits](https://getzit.org/limits): What version 0.1 does not do, and where its guarantees stop. ## Reference - [CLI reference](https://getzit.org/cli): Every Zit command. - [zit.toml](https://getzit.org/checks): Checks, generated files, dependency installs and ignore patterns. Check results are reused wherever their inputs are unchanged. - [Specification](https://getzit.org/spec): Formats, algorithms and invariants of Zit 0.1. ## Roadmap - [Roadmap](https://getzit.org/roadmap): What is planned for Zit, why, and what each item depends on. Plans, not promises; no dates. ## Project - [License](https://getzit.org/license): Zit is free software under the GNU General Public License, version 2 only, the same license as git. - [Legal](https://getzit.org/legal): Who makes Zit, the warranty disclaimer, trademarks and logos used on this site, and how measurements and comparisons should be read. ## Agent skills - [zit](https://getzit.org/.well-known/agent-skills/zit/SKILL.md): Read the Zit docs instead of answering from memory. Zit: a git extension for many developers and coding agents changing one repository at once. Use when a task involves Zit: how it works, how to set it up or configure it, or its API. ## Agent resources - [llms-full.txt](https://getzit.org/llms-full.txt): The full Markdown of every page in one file. - [Page Markdown](https://getzit.org/index.md): Append `.md` to any page URL to fetch that page as raw Markdown. - [JSON API](https://getzit.org/api/docs/pages.json): Page index of the JSON docs API; each entry links the page's JSON and Markdown forms. Described by the OpenAPI document at https://getzit.org/openapi.json. - [Agent skills](https://getzit.org/.well-known/agent-skills/index.json): Agent Skills discovery index of the skills this site publishes. - [API catalog](https://getzit.org/.well-known/api-catalog): RFC 9727 linkset of the APIs documented here. - [AI catalog](https://getzit.org/.well-known/ai-catalog.json): ARD manifest of the agent-facing resources on this site (MCP server, skills, APIs). - [agent-readability.json](https://getzit.org/agent-readability.json): Manifest of every agent-facing artifact on this site. - [Sitemap](https://getzit.org/sitemap.xml): Every indexable page URL with its last-modified date.
