What StackHangar is

StackHangar keeps the keys, logins, subscriptions and renewals behind each of your products in one encrypted vault, grouped by project.

StackHangar is a control plane for founders who run more than one product. It keeps the logins, API keys, subscriptions, domains and certificates behind each product in one place, grouped by project, and tells you before something expires or needs rotating.

#Who it is for

StackHangar is for founders and small teams whose products depend on many outside services: a hosting account, a payment provider, an email service, a domain registrar, an AI provider. Each one has a login, a key and a renewal date, and they are easy to lose track of.

#What it does

  • Keeps everything in one encrypted vault. Values, item names, notes and project names are encrypted on your device before they are stored. See what we can and can't see.
  • Groups it by project. Each product you run is a project. See projects.
  • Tells you the account behind each item. You can answer "which login do I use to fix this?" See accounts.
  • Warns you before dates arrive. See alerts.
  • Walks you through repetitive work. Playbooks guide launches, key rotation and renewals.
  • Keeps AI agents away from your values. Agents get reference IDs and your approve or deny answer, never a credential value. See agents.

#How you unlock it

There is no master password. You unlock the vault with a passkey (Touch ID, Face ID, Windows Hello, your phone or a security key). At setup you also save a recovery key. If you lose every passkey and the recovery key, StackHangar can't recover the vault, because it never holds your key.

#Where to go next

  1. Quickstart: create an account and your first item in about ten minutes.
  2. Concepts: the words the app uses and how they fit together.
  3. Signing in and unlocking: the difference between signed in and unlocked.
