What Is a ConfigStack?
A ConfigStack is a versioned environment configuration snapshot. It holds your project's keys and values—including secrets—in one place, so you can create, update, and share config without emailing or Slack-ing .env files.
Why .env files are fragile
Copying .env files between machines or teammates is error-prone and insecure. Files get lost, overwritten, or sent to the wrong channel. There's no history of what changed or who had access. A ConfigStack replaces that workflow with a single source of truth: create one Stack per environment (e.g. development, staging, production), add your variables, and share access via the app or API—no file attachments required.
Benefits of Stack-based management
Every change is saved as a version. Roll back to any snapshot or see what changed and when.
Mark values as secret and they're encrypted with AES-256-GCM. Secrets are never shown in the UI—only masked—and you control who can download.
When you need a local file, download your Stack as .env or JSON. Downloads include decrypted values, so we require re-auth for sensitive actions. Use API tokens for CI with scoped, revocable access.
