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.
1. Java enterprise (big ecosystem, fast ramp)
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
2. Model-driven / AI-native dev frameworks (complex business, built to evolve)
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
3. Form / page builders (frontend-friendly)
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
4. Database / spreadsheet (Airtable alternatives)
NocoDB / Teable — turn a database into a collaborative spreadsheet. First pick for lightweight data apps.
→ github.com/nocodb/nocodb ｜ github.com/teableio/teable
How to choose (one line, find your row)
- Admin panels / MIS, Java team → JeecgBoot / RuoYi
- Complex business, long lifecycle, self-hosting needed, want the AI-native upside → Oinone
- Pure frontend page assembly → Amis
- Lightweight data collaboration → NocoBase / NocoDB / 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.)

Grouping low-code tools by job-to-be-done is much more useful than ranking them by stars. Internal admin panels, workflow automation, BI, and customer-facing apps have very different failure modes. Picking the wrong category is how teams end up fighting the platform instead of building the product.
I encourage you to check out my original open-source project called OpenSparrow.
The project is written in PHP and JavaScript with no additional dependencies.
You can find more information on the project's website:

Useful job-to-be-done framing. One additional category worth covering is governed full-stack enterprise applications, especially customer-facing web and mobile apps, offline field apps, backend orchestration, and legacy or API integration.
Convertigo fits that row. Its Studio and Server Community Edition are licensed under AGPLv3, the project is self-hostable and actively maintained in 2026, and it combines AI-assisted development with visual frontend and backend workflows.

Disclosure: I work with Convertigo. I would be happy to provide technical details if you consider it for a future update.
