Self-host ToolJet on a VPS

Why self-host ToolJet?

ToolJet is an open-source Retool alternative that keeps internal tools on your own infrastructure.

How to install ToolJet

1. 1

   Provision a VPS

   Pick a Debian/Ubuntu template and get root SSH in about a minute.

2. 2

   Install the runtime

   Install Node.js + PostgreSQL.

3. 3

   Deploy the application

   Net what you need from the project’s official source and run it.

4. 4

   Put it behind TLS

   Reverse-proxy with Nginx and issue a Let’s Encrypt certificate.

5. 5

   Add it to your backups

   Include the data directory and database in your backup routine before you rely on it.

Practical tips

• Give ToolJet its own database user with rights only on its own schema.
• Reverse-proxy ToolJet and terminate TLS at the proxy so certificates are managed in one place.
• Take a VPS snapshot before major upgrades so you can roll back cleanly.
• Keep ToolJet patched — most self-hosting incidents are unpatched software.
