3 open-source options compared for low-code internal tool builder, with live GitHub data on each.
Last updated Repo data refreshed 24 Oct 20263 options
Our pick · ToolJet
Our pick is ToolJet because it offers an enterprise app generation platform for internal tools, dashboards, business applications, workflows, and AI agents. It excels with comprehensive AI capabilities, allowing applications to be built visually, from a prompt, or from models like Claude Code and Codex. While Appsmith is a robust platform for building admin panels, internal tools, and dashboards, integrating with many databases and APIs, and is released under an Apache-2.0 license, ToolJet stands out with its multi-modal development options and strong focus on enterprise AI integration.

"Dormant" means no commit pushed to the default branch in the last 12 months. "Archived" means the maintainers have marked the repository read-only on GitHub. "Deprecated" means the project's README says it is deprecated or no longer maintained. Stars, licence, commit and release dates come from the GitHub API (GitLab for projects developed there) and are cached for up to 24 hours. On licences: a custom licence is a licence file that isn't a single standard licence. Check the linked licence file before use. The written analysis is AI-assisted and checked against that data.
