Tilde.run

What it does

Tilde.run is an agent sandbox that provides a transactional, versioned filesystem for safe and reproducible agent execution. It turns every agent run into a transaction that can be rolled back, with code from GitHub, data from S3, and documents from Drive mounted as a single versioned filesystem. Every outbound network call is checked and logged, and changes are committed atomically on success or discarded on failure.

Who it is for

Tilde.run is designed for developers and teams building autonomous AI agents that need to operate on real production data—such as code repositories, training datasets, or internal documents—without risking data corruption, exfiltration, or credential abuse. It is particularly useful for CI/CD pipelines, agentic automation, and any scenario where agent actions must be reversible and auditable.

Why it matters

As AI agents become more autonomous, the risk of unintended side effects grows. Tilde.run addresses this by providing three key guarantees: reversibility (roll back any agent run with one command), isolation (each run is in a fresh, isolated container), and audit (every file change and network call is logged and tied to the agent). This makes it safe to let agents loose on production data, enabling faster iteration and higher trust in autonomous systems.

Launch signal

Tilde.run was launched as a Show HN on Hacker News, indicating an early-stage product seeking developer feedback. The website offers a free tier and a private preview, suggesting the product is in beta or early access. The team behind it previously built lakeFS, an open-source data versioning layer, which lends credibility to their expertise in versioned filesystems.

Brand and naming

The name "Tilde.run" combines the tilde symbol (~), commonly used in Unix to denote the home directory, with ".run" to suggest execution. This positions the product as a home base for running agents safely. The branding is technical and developer-focused, with a playful axolotl mascot that adds a friendly touch. The tagline "Let AI agents loose on production. Without the risk." clearly communicates the core value proposition.
