# Amla Sandbox

11 Hacker News commenters recommended Amla Sandbox and 2 criticized it, November 2025 to November 2026. It was recommended in 1 of 13 months.

**Verdict:** Lets AI agents run code in a constrained WASM bash sandbox, with capability-based tool validation and trace replay. Caveat: the WASM binary is proprietary and Python support is partial.

## Why people recommend it

- Fits AI agent use cases (3 comments): "This looks like it would pair really well with something like RLM" ([source](https://news.ycombinator.com/item?id=46831411)) "This seems like a great way to add that functionality!" ([source](https://news.ycombinator.com/item?id=46826864)) "That’s exactly the use case we built this for" ([source](https://news.ycombinator.com/item?id=46827051))
- Capability enforcement model (2 comments): "the capability-based tool validation layer seems useful regardless of what's running underneath" ([source](https://news.ycombinator.com/item?id=46831041)) "I really like the capability enforcement model, it's a great concept." ([source](https://news.ycombinator.com/item?id=46827552))

## What people warn about

- Proprietary WASM binary license (2 comments): "The WASM binary is proprietary—you can use it with this package but can't extract or redistribute it separately." ([source](https://news.ycombinator.com/item?id=46827023)) "The split license is a blocker for me because I build open source tools for other people to use" ([source](https://news.ycombinator.com/item?id=46827964))
