Description

Hi HN. Strata is a real-time markdown editor built around document portability across agentic workflows. The same docs live on the web, mount to disk on Linux/macOS with live CRDT collaboration intact, and render inside any MCP app (claude.ai, ChatGPT). There's also a CLI, MCP server, and API. Demo video shows live sync as ClaudeCode reads and writes legal guidance.FUSE is really neat. It can mount entire filesystems on Linux without materializing files until requested, which immediately brings to mind use-cases around knowledge bases for company files, or RAG corpus. However, the Mac side muddied the picture. We started pure FUSE + MacFUSE, but MacFUSE was an onerous kext install. Next we built on native FSKit which is kext-less, but effectively read-only. FSKit won't let you invalidate a cached read, so to push a web edit down to a local file you have to force overwrite it through your own mount to make the kernel re-cache. This is as sketchy as it sounds, and is a poor proxy for collaborative behaviors.So we put FSKit/FUSE behind a different flag and built a daemon on our existing WebSocket/CRDT stack instead. Like Google Docs meets Dropbox. The files materialize this way, but we decided it was the right tradeoff until FSKit develops their API.Doing anything meaningful over remote MCP/API requires OAuth, so there's no way around free account creation, but no credit card required. Break it and let us know how it went.https://strata.space/documentation/get-started

Could you build this?

No Mounting real-time collaborative Markdown documents as a virtual local filesystem via FUSE/NFS alongside live CRDT synchronization across web clients, CLI, and LLM interfaces requires specialized distributed systems and OS-level file system engineering.

What it would actually take: The system requires a custom user-space filesystem driver (FUSE on Linux/macOS) bridging kernel VFS calls to a distributed Conflict-free Replicated Data Type (CRDT) engine (like Yjs or Automerge). The hard part is bridging POSIX filesystem semantics (atomic writes, locks, flush buffers) into a real-time collaborative text stream over WebSockets without corrupting file state or incurring heavy latency. This demands specialized systems programming expertise in C/Rust and distributed concurrency models.
