Ren'Py Release Gate

Runs the same checker as our npm package on a Node.js runtime that pip installs for you (nodejs-wheel-binaries) - no system Node.js needed. Your files are checked locally.

Find the .rpy lines that compile clean and only break inside a player's save

Install

renpy-release-gate file

Node 18+. The same 14 rules as the VS Code extension, from a terminal or CI.

Free

• Scan one .rpy file and get every line that ships broken, each with the line number and the exact fix.
• --rules lists every rule

With a licence ($29 once)

• Sweep every .rpy file in the workspace in one pass and export a release report you keep, for CI and for your publisher.

renpy-release-gate --dir ./templates --report html --out report.html

Putting one title on Steam costs $100 in Steam Direct fees before a single crash report arrives, and every crash fix after that is another build, another store update and another refund.
