artifact-fs

ArtifactFS is a filesystem driver designed to mount large git repos as quickly as possible, hydrating file contents on-the-fly instead of blocking on the initial clone. It's ideal for agents, sandboxes, containers and other use-cases where startup time is critical.

What Hacker News says

Related, I've always wanted to see someone other than Meta run EdenFS, to hear more reports of what it's like. Feels like there's massive overlap. [Edit: I've chatted with Astra Pro some on this too now, https://chatgpt.com/share/6ace7be6-68f8-83ea-ad68-0f9d144483... ]. https://github.com/facebook/sapling/blob/main/eden/fs/docs/O... It's designed for container running, but ArtifactFS has some similarity in principle to me. The on-demand materialization. Quote: ArtifactFS is a Git-backed filesystem daemon (FUSE driver) in Go that mounts repositories as normal working trees while avoiding eager blob downloads. https://github.com/cloudflare/artifact-fs I threw together my own jujutsu powered FUSE subtree project just the other night. This was basically one-shotted, just to see how it does it, to learn more, not really intended for use. But

> yoloAI copies your worktree instead of mounting it Cloudflare/artifact-fs does lazy shallow git clones with a FUSE filesystem. https://github.com/cloudflare/artifact-fs Would that be faster? Re: sandboxing methods like Clawk, Amla sandbox, bwrap, agentvm, ARM64 MTE with wasmtime-mte: https://news.ycombinator.com/item?id=48893850 A few months ago now I started adding seccomp sandboxing to jinja2rs and then liboverlayfs support to ansiblers (which are early Rust ports). Haven't finished that, but I started working on a VM format that stores signed machine state into an OCI container repository, using the hypervisor migration support of KVM/QEMU. Though this is not safe yet if ever, VM migrations are probably another way to sandbox and deploy en masse.

a_t48·Apr 16, 2026Recommendation phrase
The ArtifactFS thing looks neat. I love this thing: https://github.com/cloudflare/artifact-fs/blob/main/examples... - it's kind of a generic image that turns into "another image" based on an argument you pass in. I recently built something similar for my own project that does the same thing except for Dockerfiles (needed for my stuff because cloud machines don't understand my registry!). I wonder if I can fork/extend ArtifactFS for other types of content addressed storage. My registry is very git-like in some ways - it has an index, files are content addressed, etc.
