How much RAM does ToolJet need?

Plan on 4 GB for typical use; add headroom if you expect many concurrent users.

Can I run other things on the same VPS?

Yes — size the plan so ToolJet plus your other workloads fit in RAM with room to spare.

Development

A low-code platform for internal tools.

Connect databases and APIs, then build internal apps with a visual builder.

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

1
Provision a VPS
Pick a Debian/Ubuntu template and get root SSH in about a minute.
2
Install the runtime
Install Node.js + PostgreSQL.
3
Deploy the application
Net what you need from the project’s official source and run it.
4
Put it behind TLS
Reverse-proxy with Nginx and issue a Let’s Encrypt certificate.
5
Add it to your backups
Include the data directory and database in your backup routine before you rely on it.

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.
