> A Go sandbox service for running untrusted code (e.g. written by an AI agent) that reports the isolation tier of each run and lets requests demand a minimum tier.

## Useful for

- Run LLM-agent-generated code in an isolated sandbox with a guaranteed kernel or vm tier
- Restrict agent code's API access via a grant to specific routes without exposing credentials
- Verify determinism of an agent-written controller by comparing SHA-256 fingerprints of two runs

## Why it’s here

- Star-counter measurements on 2026-10-12 (UTC), 02:19–04:25: 10 → 13 stars (+3). This is the change over that interval.
- Estimated end-of-day forecast: about +13 stars, using observed gains and the previous day.
- Before this, the repository barely got any stars — about 0 per day.
- The repository is 32 days old and already has 13 stars.

## Star trust

Star growth looks organic.

Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer.

## Numbers

- Forks: 1
- Issues and pull requests: 0
- Watchers: 1
- Average over the last week: 4 per day
- Usual pace: 0 per day
- Stars in the last hour (measured): 2
- Latest release: v0.21.0 (2026-10-09)

   gVisor is an application kernel implementing a Linux-like interface in userspace in Go. It isolates containers from the host kernel, reducing container escape risk when running untrusted code.

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
