Top 18 Open-Source Low-Code Platforms Every Developer Should Know

Low‑code has become a hot topic at recent developer and tech conferences. Unlike traditional programming with source code, low‑code platforms let users build applications through graphical wizards, drag‑and‑drop components, and visual logic builders.

The concept dates back over a decade to early no‑code tools like PWCT, but only now has it gained broad community support, with dozens of platforms emerging for both rapid prototyping and production use.

1. Saltcorn

Saltcorn is a no‑code database‑management web app with a dashboard, ecosystem of views, and themable UI. Users with little coding experience can create rich interactive database applications in minutes, and companies can build internal tools quickly.

Example apps include blogs, address books, project management, issue trackers, wikis, and team management. Saltcorn is released under the MIT license.
