ILLA Builder
Open-source low-code builder for internal tools, a self-hostable Retool alternative
Overview
ILLA Builder is an open-source low-code platform for rapidly building internal tools by connecting components to databases, APIs, and third-party services with real-time collaboration. It positions itself explicitly as an open-source Retool, with a drag-and-drop UI and many built-in integrations. It is Apache-2.0 licensed and self-hostable, though active development has slowed.
Where it falls short of Retool
- Development has slowed; releases and commits are infrequent.
- Smaller connector catalog and ecosystem than Retool.
- Fewer advanced governance/enterprise features.
- Documentation and community support lag behind larger alternatives.
We list the gaps honestly so you can decide if the trade-off is worth owning your data.
