Detailed Review
ToolJet is another open-source option for internal tools. It gives teams a visual builder for common admin interfaces, while still supporting database queries, API calls, JavaScript, and server-side actions when the workflow needs more control.
The built-in ToolJet database is helpful for simpler apps that do not already have a dedicated data source. For more serious workflows, teams can connect existing databases and services instead.
ToolJet is still maturing compared with Retool, but it is appealing for teams that want a self-hostable internal tool platform and are willing to trade some polish for openness and flexibility.
