Open Source
Free and open source under the Apache-2.0 license; you run it on your own Linux/KVM and Kubernetes infrastructure and pay only for that compute.
Best for
Platform teams building agent products that need self-hosted, hardware-isolated sandboxes for agent and user code, especially those looking for an E2B-compatible backend.
Not ideal for
Individual developers wanting a local sandbox for a single coding agent; setup requires a Linux x86_64 host with KVM and a Kubernetes (Kind) deployment.
A production-grade, open-source microVM sandbox platform from a major AI company that gives agent builders a credible self-hosted alternative to hosted code-execution sandboxes.
Open-sourced by Perplexity in mid-October 2026 as the sandbox platform behind Perplexity Computer, with coverage on Hacker News and in the press; the repository receives daily commits, with updates on October 21, 2026.
