Mantle Bot · every plan

Ask about your integrations.

A chat in the corner of the dashboard answers from your workspace’s own data: what changed in the Stripe API, why a migration failed, which integrations you have. It reads; it never changes anything.

Free
Answers from your integrations, repositories, detected changes and migration status.
Pro and Max
Full access: adds each migration’s edits and the output of every check.
Enterprise
Full access, and a custom knowledge base for your own documentation.Knowledge base coming soon
Mantle BotExample · sample data

What changed in the Stripe API?

One change affects you. Stripe now takes billing_cycle_anchor as an object when you update, resume or preview a subscription.

  • acme/payments: 3 call sites in 3 files, and 1 test
  • Migration verified: typecheck, lint, 212 tests and build passed

Pull request #214 is waiting for review on the Pull Requests page.
