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

Let AI agents loose on production. Without the risk.

Tilde turns every agent run into a transaction you can roll back. Code from GitHub, data from S3, and documents from Drive show up as a single versioned filesystem. Every outbound call is checked and logged. Autonomous code, finally safe to use against real data.

Reversible by default Roll back any agent run with one command

One filesystem, all your data GitHub, S3, and Drive as a single ~/sandbox

Contained by default Isolated runs, every network call audited

You stay in control Per-action policies and human approval gates

Versioned Composable Filesystem

A real POSIX filesystem - any tool, any language, no SDKs. Mount code from GitHub, training data from S3, and documents from Google Drive as a single ~/sandbox. Every file is versioned from the first commit, and any agent run can be rolled back instantly.

Safe Serverless Sandboxes

Stop fearing the rogue-agent outcome. Each run is a transaction in a fresh, isolated container - on a clean exit, changes commit atomically; on failure, nothing changes. No backups to restore, no manual cleanup, no infrastructure to manage.

Network Isolation

Stop data exfiltration, credential abuse, and prompt-injected callouts before they leave the box. Cloud metadata, private networks, and unauthorized hosts are blocked by default. Every outbound request is policy-checked and logged against the agent that made it.

Time Travel & Audit Trail

Know exactly what happened, who did it, and why - down to the file. Browse the full timeline, inspect diffs, and revert any commit instantly. Every change is tied to the human, process, or agent that produced it.

Agent-first RBAC

Agents are first-class citizens, with their own scoped permissions - never your full user access. Allow, deny, or require human approval per agent, per repository, per action. Granular policies in a simple, readable DSL.

## Quickstart

Run commands and interactive shells in sandboxes from your terminal. Built for CI/CD and agentic automation.

Run agents in interactive shells or one-shot sandboxes, stream output, and commit. Done in a few lines of Python.

Tell Claude to spin up a sandbox, run your agent, and atomically commit the results. In plain English.

01 setup

Compose Filesystem

Build a versioned repository from GitHub, S3, Drive, and more. Spin up an isolated sandbox with everything your agent needs.

github s3 drive ~/sandbox

02 execute

Run Agent

Your agent runs in isolation. Every file write is staged. The entire run is captured as a transaction -- committed atomically or discarded entirely.

$ tilde exec agent.py

03 decide

Commit or Rollback

Review the results. Approve and commit – or roll back and discard. One command, zero risk.

✓commit or ↺rollback

Built by the team behind lakeFS

We built lakeFS - the open-source data versioning layer trusted by some of the world's largest organizations to manage billions of objects. Tilde is built on that same battle-tested versioning foundation, reimagined as the filesystem platform the autonomous AI agent era demands.
