Last week, we published an article titled "The Top 12 Open-Source No-Code Tools with the Most GitHub Stars," which received much appreciation. Many friends commented asking why well-known products like n8n and Appsmith were not on the list. The reason is that we based this list on the "no-code" tag on GitHub, while these products were only tagged as "low-code."

In today's article, we will review low-code projects. It's important to note that there is some overlap between no-code and low-code products (as these concepts do share similarities). Building on our previous article, we will add three additional dimensions to comprehensively evaluate these projects:

1. Open Source License
2. Number of Active Contributors
3. Acceptance of External PRs

During our exploration of the most popular open-source low-code projects on GitHub, we discovered several compelling tools.

NocoBase, with its highly scalable plugin architecture, enables businesses to quickly build and expand applications.

Supervision focuses on simplifying the training, deployment, and monitoring of computer vision models, providing efficient data annotation and model optimization tools.
