Getting Started with ToolJet: Self-Host Your Internal Apps in Minutes

What Is ToolJet?

ToolJet is an open-source low-code platform that lets you build internal tools, dashboards, business applications, and AI agents without writing boilerplate code. Think of it as an open-source alternative to Retool — but with AI-powered features, a built-in database, and full self-hosting capabilities. With 38,000+ GitHub stars and an active community, ToolJet has become the go-to platform for teams that need to ship internal apps fast without vendor lock-in.

Why Self-Host ToolJet?

Self-hosting ToolJet gives you full control over your data. Whether you are in fintech, healthcare, or any regulated industry, running ToolJet on your own infrastructure means sensitive data never leaves your network. You can deploy it via Docker, Kubernetes, AWS EC2, or even a Raspberry Pi cluster. The community edition is free under AGPL-3.0, with no feature gates on the core builder.

Quick Start with Docker

Getting ToolJet running locally takes less than two minutes. Make sure you have Docker installed, then run:

docker pull tooljet/tooljet:latest
docker run -d --name tooljet -p 8080:8080   -e SECRET_KEY_BASE=***   tooljet/tooljet:latest

Once the container starts, visit http://localhost:8080 and create your admin account. ToolJet will guide you through the setup wizard — connect your first database, create a workspace, and invite your team.
