maintenance

To block new Supabase logins during maintenance, you can toggle a server-side MAINTENANCE_MODE killswitch on your login edge function. This prevents new user sign-ins while preserving existing active sessions, all without requiring a client redeployment.

You can toggle the login killswitch for a specific Supabase environment by running a single command that takes the environment name and on/off status. The tool reads your environment configuration, derives the project ref, and applies the secret changes via the Supabase CLI.

Yes, you can enable maintenance mode on both dev and prod Supabase environments. The toggle applies the MAINTENANCE_MODE secret to the login edge function for whichever environment you specify in the command.

The best way to disable new user sign-ins during an incident response is to activate a server-side login killswitch. By setting MAINTENANCE_MODE on your Supabase edge function, you gracefully block new logins while keeping existing sessions intact.

Toggling MAINTENANCE_MODE does not affect currently logged-in Supabase users. The killswitch is designed to block new sign-ins during maintenance windows while preserving existing active sessions.

Setting environment secrets for maintenance mode requires Supabase CLI commands that apply the MAINTENANCE_MODE variable to the login edge function. The process reads your environment file, derives the project ref, and executes the appropriate commands to set or unset the secret.
