ashad-red

Node-RED, always on.

This server runs Node-RED 5. It saves your flows to a database, so they survive restarts, and keeps itself awake on free hosting.

What's running here

Everything below is set up by environment variables on the server. You don't need to change any code.

Flow editor
At /red. It asks for a username and password when the server has them set.
Storage
Flows, credentials and settings are saved to Turso or PostgreSQL, so they survive restarts and redeploys. With no database set, they're saved to a local flows.json.
Stays awake
On Render, the app requests its own address every 10 minutes so the free plan doesn't put it to sleep.
Theme
The editor follows your system's light or dark setting. Change it any time in the editor's settings.

Run your own

Free accounts on Turso and Render are enough to keep one Node-RED running all month.

  1. Create a Turso database

    Sign up at app.turso.tech, create a database, then copy its URL and create a token for it.

  2. Deploy to Render

    Click the button and paste in the database URL, the token, and a username and password for the editor.

    Deploy to Render

  3. Sign in to the editor

    When the deploy finishes, open https://<your-app>.onrender.com/red and sign in. Your flows are saved to Turso every time you deploy them.

Make it yours

Common changes, and where to make them.

Add nodes

Install them from Manage palette in the editor menu. To keep them across rebuilds, also add the package to package.json. Browse nodes in the Node-RED library.

Turn on the editor login

Set NODE_RED_USERNAME and NODE_RED_PASSWORD in your host's environment settings, then restart.

Replace this page

Put your own files in public/. They're served from the site root.

Serve the editor at the root
