FAQ
The exact review scope, isolation boundary, platform support, model role, and current access state.
Runrail reviews an existing AI-generated candidate branch against a clean base. It binds the review to the base commit's optional review contract, records bounded path, diff, secret-like, and binary checks, validates supported Python, JavaScript, JSON, TypeScript, TSX, and JSX files without running project code, and exports a local decision packet.
Runrail materializes tracked candidate files in a separate local review directory without checking the branch out in the source repository. The source checkout stays unchanged, and Runrail never applies the candidate automatically.
No. The built-in verifier performs non-executing Python, JavaScript, JSON, TypeScript, TSX, and JSX syntax or parse checks. It parses Git blob strings without loading project configuration, plugins, dependencies, or module resolution. It does not import project code, run package scripts, or execute your test suite. Unsupported changed source types are reported for manual review; semantic review, security review, and the final merge decision remain your responsibility.
Runrail Desktop includes launchers for Windows, macOS, and Linux. The CLI also supports WSL2. Node.js 20+, Python 3.11+ with venv, and Git are required.
No. The default candidate recommendation is deterministic, offline, and model-independent. DeepSeek is an optional BYOK second opinion after explicit network consent; it receives minimized metadata and has no execution, approval, apply, or merge authority.
The browser workspace can compare related local audit files without an account or purchase. Pro adds the Desktop Revision Workspace: runrail recheck binds a prior audit and its Review Coverage to the current review, carries only exact unique hunk attention, and exports a deterministic Re-review Map. The separate runrail compare command remains available for finding and priority deltas when subscriptions are available.
New subscriptions are currently paused. Anyone can use the browser-only recorded audit at /workspace/ or download the checksum-verified 2.4.14 preview from /install/, run doctor and the safe sample, then use desktop --repo . from a local Git worktree to perform one real local candidate review without an account or card. The preview includes exact-hunk inspection, Review Coverage, a source-free correction brief, and a checksum passport. Another review, rerun, agent launch, recurring history, and Pro continuity require enrollment. Windows is unsigned and macOS is unsigned and unnotarized.
