What the numbers say
- CNCjs and LinuxCNC have a similar number of GitHub stars (2.7k vs 2.5k).
- LinuxCNC had more commits in the last 12 months (1,821 vs 51).
- LinuxCNC published a release more recently (v2.10.0-pre2 on 2026-09-28; CNCjs's latest is v1.11.5 on 2026-09-13).
- CNCjs is licensed under MIT, LinuxCNC under GPL-2.0, LGPL-3.0. CNCjs's license is permissive; LinuxCNC's is copyleft (changes you distribute must stay open).
- CNCjs is written in Nodejs; LinuxCNC in C.
- Deployment options listed upstream: CNCjs: none listed; LinuxCNC: deb.
- Only CNCjs has a Docker Hub image that we detected (cncjs/cncjs).
- Our rough hardware estimate is lighter for LinuxCNC (~512 MB server) than CNCjs (~1 GB); this is an estimate from the stack and category, not a benchmark.
Summary: CNCjs leads on Docker Hub availability; LinuxCNC leads on commit activity. The right choice depends on the features you need — read both project descriptions and docs.
This summary is generated from GitHub, Docker Hub and awesome-selfhosted data as of 2026-11-15. It does not rate features or quality.
