Major lets you deploy internal tools directly from your laptop while keeping access governed in one place. Engineers who build internal apps use the CLI to:
  1. Deploy code instantly – scaffold apps from templates, push with a single command, and ship a new version in seconds.
  2. Manage access & permissions – assign roles in the web editor and ensure every action respects RBAC.
  3. Connect to internal resources securely – route database and API traffic through the Major control plane instead of punching new holes in your network.
Local traffic always flows local app → Major API → resource. When you run major app start, we mint a short-lived JWT in your .env file so every request is authenticated through the platform.
