If you want an open-source low-code platform you can self-host, read the source of, and not get locked into, there's no shortage of options — but they differ wildly in kind, and picking the wrong category wastes weeks. Here's a roundup of the open-source (and China-origin but globally usable) low-code projects still active in 2026, grouped by what you're trying to build. Each has a repo link — if one fits, go star it and support the maintainers. Star counts are approximate and drift over time — treat them as a heat signal, not a scoreboard.
JeecgBoot — ~36k+ ⭐
Low-code + no-code dual engine, very active community. Admin panels, MIS, OA, ERP, AI knowledge bases — a go-to for Java teams.
→ github.com/jeecgboot/JeecgBoot
RuoYi — tens of thousands ⭐
The classic permissions scaffold. Lightweight, easy to start, rock-solid base for admin systems, with thorough docs and tutorials.
→ github.com/yangzongzhuan/RuoYi
Oinone — GitHub ~2.7k ⭐ (AGPL-3.0)
Unlike drag-a-form no-code, this is a 100% metadata/model-driven dev framework where AI and developers share one metadata model — the AI emits maintainable metadata changes, not throwaway code. Built for complex business and deep enterprise customization, with self-hosting and a smooth monolith→distributed switch. Front + back end open source (AGPL-3.0). One docker compose
and it's up in ~5 min. Has run in the core systems of billion-scale enterprises. Strong product, badly underrated star count — worth getting in early.
→ GitHub: github.com/oinone/oinone-pamirs
Amis (Baidu) — tens of thousands ⭐ JSON config → pages. A backend-UI assembly powerhouse with great docs.
→ github.com/baidu/amis
NocoBase — plugin-based, no-code + low-code, self-host friendly, strong i18n.
→ github.com/nocobase/nocobase
NocoDB / Teable — turn a database into a collaborative spreadsheet. First pick for lightweight data apps.
→ github.com/nocodb/nocodb ｜ github.com/teableio/teable
The whole point of open source: it runs, you can read the source, you can self-host, and you're not locked in. Before you commit, clone a couple and actually run them — nothing beats hands-on.
If this roundup helped, drop a ⭐ on the projects that fit — especially the underrated open-source ones. (Disclosure: I work with Oinone — but every project above earns its place on its own merits; pick what fits your row.)
