Amla Sandbox
Ranked 7 of 12 cloud sandboxes by recommenders
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.

What people warn about
Each mark is one comment
Proprietary WASM binary license
“The WASM binary is proprietary—you can use it with this package but can't extract or redistribute it separately.”
Comment from 30 Jan 2026 in “Show HN: Amla Sandbox – WASM bash shell sandbox for AI agents” “The split license is a blocker for me because I build open source tools for other people to use”

“will hit some limitations (aka: not really full Python support, partial JS support)”
