Mesa

Mesa is a versioned filesystem and virtual filesystem platform built specifically for AI agents. Instead of losing context between sessions, agents can access persistent files across every task, keeping their work organized and ready to pick up right where they left off.

Through a single API, agents can create isolated branches, run parallel agent swarms, track every change, request human approvals when needed, and roll back to earlier states whenever something goes wrong. This makes it easy to experiment safely while keeping humans in control of what gets merged or deployed.

Mesa supports POSIX-compatible filesystem access, so agents can work with large files, shared memories, documents, code, datasets, models, and media just like they would with a familiar filesystem. Everything stays consistent and accessible no matter how many agents are working at once.

Performance is built in: MesaFS delivers sub-50ms reads and writes, instant workspace forks, and strong consistency, even under heavy parallel workloads. Fine-grained access controls and flexible enterprise deployment options make Mesa suitable for teams with strict security and compliance requirements.
