Step-by-step fixes for keys, leaks and shutdowns

The jobs founders put off until something breaks, written down as checklists. Each one works with any provider, and each one runs inside StackHangar against your own stack.

Rotate an API key without downtime

Create the new key, update every deploy target, redeploy, verify, and only then revoke the old one. Also covers database passwords and domain renewals.

Leaked API key: what to do in the first hour

A key ended up in a public repo, a chat or a log. Replace it, revoke it, check the provider for misuse and find every other copy, in the right order.

Shut down a SaaS product cleanly

Export your data, cancel every subscription, revoke the keys, decide each domain and close the accounts, so nothing keeps billing or keeps working after you're done.

SaaS handover checklist: sell or transfer a product

Inventory every account, key and domain, move ownership, rotate everything you held and remove yourself, so a sale doesn't leave you with access you shouldn't have.

There is also Launch, for setting up a new product with the right accounts and keys from day one.
