Our Analysis
If you need to build internal tools — admin panels, dashboards, CRUD apps for your team — without writing frontend code from scratch, ToolJet gives you a drag-and-drop builder that connects to your databases, APIs, and SaaS tools. Think Retool but open source and self-hostable. Connect to Postgres, MySQL, MongoDB, REST APIs, GraphQL, Google Sheets — 50+ data sources. Drag components onto a canvas, wire them to queries, and you have a working internal tool. It handles auth, permissions, and audit logs. 37.7K stars, AGPL-3.0, growing at +44/wk. Self-host for free or use their cloud. The catch: AGPL-3.0 means if you modify ToolJet and serve it to users outside your organization, you must open source those changes. The free self-hosted version has feature limits compared to the paid tiers — SSO, audit logs, custom branding, and granular permissions are gated behind Business ($20/user/mo) or Enterprise pricing. For a team of 10, that's $200/mo for features many teams consider essential. The open source version works for small teams that don't need SSO, but the paid features are exactly what growing teams need.
