Slack is not a secret store
Copy-pasting DATABASE_URL into chat creates permanent leaks in scrollback. Encrypted storage with project-level files is the minimum bar for client work.
OpsRunr Environments encrypts contents at rest and tracks which teammate last updated a file, enough for small teams without enterprise secret managers.
A practical workflow
Create one project per client app. Store `.env.development` and `.env.production` separately. Rotate values by saving a new encrypted version when credentials change.
Start on free project caps; unlock Environments when you juggle more client workspaces than the free tier allows.
