What is railyard?

Railyard is a Rust-built secure runtime for Claude Code, Anthropic's AI coding agent, letting you skip permission prompts without risking disasters like terraform destroy wiping prod or rm -rf ~/ trashing your machine. It intercepts every tool call, blocks/approves commands via customizable YAML policies, fences paths to protect ~/.ssh and /etc, and snapshots files for one-command rollbacks like railyard rollback --session id. Think Deno as a secure runtime for JavaScript and TypeScript, but optimized for AI agents handling Bash, file edits, and infra tools.

Why is it gaining traction?

It stands out by enabling truly autonomous sessions—99% of safe commands like npm install flow in under 2ms, while evasion tricks (base64 pipes, eval hacks) get caught early, unlike manual Copilot guards or how to secure GitHub Copilot setups. Kernel sandboxes via macOS sandbox-exec or Linux bwrap add zero-overhead protection, plus traces and self-healing hooks prevent agents from disabling it. Devs love the recovery: ask Claude to rollback changes or tweak rules without restarting.

Who should use this?

Claude Code power users building apps with AI—backend devs managing Terraform/Pulumi stacks, full-stack teams automating DB migrations (Drizzle/Prisma), or infra engineers testing agents on live-like envs. Ideal if you've lost data to rogue agents or hate clicking "allow" endlessly, but skip if you're not deep into Anthropic tools yet.

Verdict

Strong try for Claude Code devs (cargo install, then railyard install)—solves real pains with solid docs, 141 tests passed, and a pentest report. At 11 stars and 1.0% credibility, it's early but low-risk Rust; productionize policies before heavy infra use.
