LayerFS

LayerFS is an open-source filesystem providing writable workspaces for AI coding agents over shared history.

LayerFS is an open-source filesystem designed for AI coding agents. It provides a shared history where each agent tool call gets a complete, writable workspace. Compute exists only while commands run, and agents on different computers share a serverless store without a database server. It supports massive parallelism, automatic checkpoints, recursive branching at zero cost, and deduplication for ultra storage optimization. The system avoids dependency re-installation by keeping ignored files in every commit, reducing mount times significantly. It uses append-only objects, content-addressed storage, and custom conflict rules to manage multi-agent development.
