免费MES、开源MES Manufacturing Execution System cloudmes freemes
free-mes is a Chinese-language open-source Manufacturing Execution System built on Spring Boot 2, Vue 3, MySQL 8, Redis, and MinIO. It covers the core MES workflow: production orders, scheduling, shift calendars, task tracking, and operator reporting. Aimed at small-to-mid Chinese manufacturers who need a deployable MES without paying for commercial licenses.
The framework layer is well-structured — separate starters for data permission, security, web, and async concerns follow the pattern of established Spring Boot scaffolding projects like RuoYi-Vue-Pro, which this appears to be based on. Row-level data permission filtering via AOP and MyBatis interceptors is genuinely useful in a multi-department factory context and not trivial to implement correctly. The Docker-based deployment docs lower the barrier for shops that don't have dedicated ops staff. The scheduling and shift calendar features cover real production complexity — staggered shifts and calendar-aware planning are often missing from cheaper alternatives.
The README explicitly states the open-source version no longer gets demo access, technical support, or bug answers — the real product is the paid commercial version, which is described as 'a completely different platform.' That's not open source in any meaningful sense; it's a demo for the sales funnel. Still on Spring Boot 2, which hit EOL in November 2023; no indication of a migration path. The codebase appears derived from RuoYi-Vue-Pro with MES modules bolted on, so you're inheriting that project's opinions and any bugs. No English documentation, no English issue tracker, and given the no-support policy, adopters outside China who hit problems are on their own.
