Editorial Evaluationagent-run vs v0 by Vercel: compare documented features, pricing, and pros/cons below — the best choice depends on your primary workflow.
Choose agent-run if: Free (Open Source, GPL-3.0)
agent-run is a tiny (under 1 MB) standalone binary that runs coding agents — pi, opencode, codex, or claude — inside a Bubblewrap (bwrap) sandbox. Its purpose is to let an agent operate freely inside your project without being able to touch anything outside it: the host filesystem is mounted read-only by default, and only paths you explicitly allow become read-write. It's built for catching agent mistakes, not malicious code — if an agent tries to delete your home directory or exfiltrate a file, the sandbox contains it. Configuration is a simple TOML file with per-tool sections (tools.claude, tools.codex, …) controlling env inheritance, network access, and mounts. The bwrap binary is compiled for the target platform and embedded directly into agent-run, then exec'd at runtime via a memfd, so there's no separate dependency to install. It currently supports aarch64 and x86_64 Linux and depends on unprivileged user namespaces.
