Mega
Open-source Git-compatible monorepo engine that stores AI agent session context alongside code
If your agents keep re-cloning the same giant repo and their reasoning vanishes after each diff, Mega2 targets both problems with Libra's capture hooks and ScorpioFS's on-demand mount. Both are the pieces worth a trial, and both run free under MIT/Apache-2. Budget for operating a stateful backend yourself, though.

Skip Mega2 if you want a hosted version-control service you don't operate, or if your repos are small enough that a normal clone and a chat window are sufficient context for your agents.
The community edition excludes the Web UI and Change List, so anything you build around those surfaces is extra engineering on your side
Mega2's community edition is open source under MIT and Apache-2. For a platform team already running that infrastructure, that is often cheaper than per-seat hosting at monorepo scale; for a small team without ops capacity, the free code is the cheap part.

What is Mega?
Mega — Open-source Git-compatible monorepo engine that stores AI agent session context alongside code. Best for Platform engineers building toolchains for AI coding agents, Teams running several agents against one large monorepo, Organizations that want agent session context stored alongside code. Free to use.
Mega2 is an open-source monorepo engine and Git hosting backend for teams whose AI coding agents all work against one large codebase. It is built around a single Rust server plus two companion clients: Libra for version control and session capture, and ScorpioFS, a FUSE-based virtual file system. The server speaks Git Smart HTTP for clone, fetch and push, offers read-only SSH, keeps one public main trunk on ordinary paths, and isolates third-party code in a separate ImportRepo. Git objects, LFS large files, build artifacts and OCI images share local or S3-compatible storage with Postgres metadata. The design premise is that a diff erases the reasoning behind it. An optional HTTP API captures agent sessions, events, checkpoints and redacted transcript snapshots, so intent, planning and tool calls stay attached to the repository rather than living out their days in a chat window. Libra ships capture hooks for Claude Code, Codex and OpenCode plus a terminal interface for browsing session and checkpoint history. ScorpioFS goes after clone-storm overhead: instead of every agent workspace paying for a full clone, it mounts a remote monorepo path locally and fetches files on demand. That is the piece to benchmark against your current clone times before committing. On the managed-hosting axis, Mega2 and GitHub or GitLab split on priorities: hosted platforms give you uptime SLAs and a polished UI, while Mega2 puts agent-native session context and on-demand mounting inside the repo itself. The trade is that you self-operate a stateful Rust backend on Postgres and object storage, and the open-source edition runs in trunk/storage-only mode without the Web UI or Change List.
Key features
- Git Smart HTTP clone, fetch and push
- Read-only SSH access to repositories
- Trunk-based monorepo with a single public main trunk
- ImportRepo for isolating third-party codebases
- Optional HTTP API for agent session capture
- Session, event, checkpoint and transcript recording
- Redacted transcript snapshots attached to repo history
- Shared object storage for Git objects, LFS, build artifacts and OCI images
- Postgres metadata with local or S3-compatible storage
- ScorpioFS FUSE virtual file system for on-demand access
- Mount a remote monorepo path as a local workspace
- Libra capture hooks for Claude Code, Codex and OpenCode
- Libra terminal UI for browsing sessions and checkpoints
- Webhook notifications
- Rust server with Docker Compose evaluation stack
Behind the verdict
We'd reach for Mega2 when the pain is specific: multiple AI agents hammering one large monorepo and a reviewer who cannot tell why a change happened. Libra's session capture is the differentiator nobody else ships in the same box, and ScorpioFS's FUSE mount is the practical answer to clone storms. The friction shows up fast if you expect a service. This is a Rust server you run on Postgres and S3-compatible storage, with host networking on Linux and a Compose stack for evaluation. Nobody is on call but you. The open-source edition runs trunk/storage-only and omits the Web UI and Change List. Plan around API, CLI and terminal workflows rather than clicking through a hosted interface. Against GitHub or GitLab, you give up managed uptime and a mature UI review flow. What you get back is context attached to history and on-demand mount instead of full clone. For a platform team already running Postgres and object storage, that trade is defensible. Where it bites: docs are Chinese-first, the community is small, and the whole value proposition depends on your agents actually using Claude Code, Codex or OpenCode so the capture hooks matter. If your workflow is multi-repo by design, stop here.
Limitations
- Mega2 runs in trunk/storage-only mode in the open-source community edition, which does not include the Web UI or Change List, so features depending on those are outside the free codebase.
- You self-operate a stateful backend — Rust server, Postgres metadata, and local or S3-compatible object storage — and own its availability.
- The homepage is largely in Chinese, raising reading cost for English-speaking teams, and adoption assumes comfort with Git internals plus running stateful services.
- Agent session capture is optional and, where transcripts are involved, depends on what is available and redacted from client hooks; the clone-versus-mount diagram is explicitly labeled illustrative, not a performance benchmark.

GeneratedReal-world workflow fit
Concrete scenarios for the personas Mega actually fits — and what changes day-one when you adopt it.
You pull the Compose file from gitmega.ai, start Mega2 locally with Docker Compose, and complete a first Git push against the trunk-based main path before wiring ScorpioFS into an agent workspace.
Outcome: A working Git-compatible monorepo backend on Postgres and local object storage, with an evaluation path for on-demand mounts instead of full clones.
You enable Libra's capture hooks for Claude Code, Codex or OpenCode, point them at the Mega2 HTTP API, then browse session and checkpoint history from the Libra terminal UI.
Outcome: Session records, checkpoint metadata and redacted transcripts sit alongside the code history, so the next agent or reviewer can see intent and verification, not just the diff.
You configure Mega2 with S3-compatible object storage so Git objects, LFS large files, build artifacts and OCI container images share one backend behind a single Git host.
Outcome: Four artifact classes on one platform with one storage layer to size, back up and monitor.
Use cases
- Give coding agents a single global view of code spread across what used to be multiple repos
- Mount a large monorepo through ScorpioFS instead of cloning it for every agent workspace
- Capture Claude Code, Codex or OpenCode sessions so the reasoning behind a diff stays with the repo
- Store Git objects, LFS files, build artifacts and OCI images on one shared object store
- Run a Git-compatible trunk-based monorepo where developers keep their existing Git habits
- Stand up a local evaluation stack with the Docker Compose file and complete a first push
Setup time & first value
How long it actually takes to get something useful out of Mega — broken out by persona, not the marketing-page minute.
The documented path is quick if Docker is already in place: download the Compose file, run it, and reach the local instance at 127.0.0.1:9000, then do a first push. Budget an afternoon for a real repo with monorepo path and main-trunk rules, and longer if you add Libra hooks and ScorpioFS mounts. Expect days, not hours, before a team depends on it.
Switching to or from Mega
How to bring data in from common predecessors and how to get it back out — written for the switcher, not the buyer.
- →From GitHub or GitLab: push existing history into Mega2 over Git Smart HTTP against the trunk-based main path
- →From a multi-repo setup: consolidate application code into the monorepo and place third-party code in an ImportRepo
- →From a plain Git server: point clients at Mega2's Git Smart HTTP endpoint and a read-only SSH endpoint
- ↗To a hosted Git platform: Mega2 speaks Git Smart HTTP, so history clones out the same way it came in, though agent session records and checkpoints live in Mega2's own capture layer
- ↗To a plain Git host: expect to lose the session-capture history and the ScorpioFS on-demand mount unless you rebuild them
