Mantle says it tracks third-party API changes, updates affected code, runs a repository’s checks, and opens a pull request for review.

Landing page captured for the 2026-09-23 issue.

For: Teams maintaining Stripe integrations in TypeScript or JavaScript
Worth noticing: The sample run traces one removed Stripe parameter to three files and reports 184 passing tests; the page labels the replay sample data.

Field notes

The page distinguishes Mantle from a general coding assistant and describes a single maintenance task: tracking changes in APIs a repository depends on. Its sample Stripe run names the changed parameter, lists three affected files, and displays typecheck, lint, test, and build results before showing a pull request marked for review. The replay is explicitly sample data, and the page says Stripe is the current integration, with others to follow.
