ToolJet vs Budibase
Both are alternatives to Retool. Here's how they stack up — verified facts, no spin.
Also searched as Budibase vs ToolJet — same comparison, one verdict.
ToolJet
Lighter than Appsmith, AGPL, and quick to stand up.
ToolJet is a low-code builder for internal tools with a visual app designer, around fifty data-source connectors, and a notably light deployment — it will run comfortably on hardware you would consider too small for Appsmith. AGPL-3.0 with roughly 38.3k stars. The licence is the thing to read carefully: AGPL is strong copyleft, which matters if you intend to modify it and offer it as a service to others. For ordinary internal use it changes nothing at all.
Budibase
Brings its own database, so a tool can exist before the data does.
Budibase differs from the others in a way that matters more than it sounds: it includes an internal database, so you can build a working tool before you have a backend to point it at. That makes it the fastest option for the common case of a team that needs a form, a table and some approvals — not a dashboard over an existing production database. It also connects to external sources when you have them. GPL-3.0 core with a commercial enterprise tier, around 28k stars.
