yawnxyz · x · 2026-08-21

Open-source smolvm v1.9.0 makes 'branchable compute' production-ready. A demo shows a smol VM being forked many times with a browser + agent workload inside.

It's a portable, lightweight, self-contained Linux VM CLI built around isolation + speed: sub-second cold start, cross-platform (macOS/Linux/Windows), elastic memory—aimed at giving agents isolated execution by default. 5.6k GitHub stars.
