Show HN: Tilde.run – Agent Sandbox with a Transactional, Versioned Filesystem

Re:Show HN: Tilde.run – Agent Sandbox with a Transactional, ... by kushalpatil07 on Wednesday May 06, 2026 @01:04PM (#48038635)

I was trying to build an agent. None of the sandboxes out there had solved the filesystem problem. I want my agent to have a persistent storage, and that stays forever. Like a human with a computer. When the agent spins up again, it has access to the computer with the same files.

I had to create my own setup using aws s3 filesystem and docker for this.

Does Tilde solve for this?

Snapshotting a filesystem is trivial with e.g. btrfs. You can hook snapshot creation in your agent.

That is a single one liner of btrfs subvolume snapshot, in a single hook configuration file, ready to be valued at $10B as quantum agentic versioned sandbox startup.

Part of the appeal (subjective, I know) of versioning is stuff like human-in-the-loop approvals. Think of a pull request: a change is requested by an agent, a human approves, changes get merged atomically. Even if other changes were applied since creation.

Hey, this is exactly what we do at https://instavm.io Agents get persistent storage that outlive the sandbox and when the agent spins up again you get access to the computer with same files.

Nanoclaw mounts each agent's folder to the ephemeral container.

which is the bare minimum that I hope people are doing , nothing about trusting a third party is any less or more secure.

Isn't that like working on a codebase with an agent?

This is something solved by a bunch of new sandboxes including ours - SmolVM

Agent Sandboxes is the official k8s solution for this.
