Questions
Is there really no paid plan?
No. Chart.ts is MIT licensed. Every feature, every chart type, every framework package is free. Use it in personal projects, startups, or enterprise apps.
Can I use it commercially?
Yes. The MIT license allows commercial use, modification, and distribution. No attribution is required, though it is appreciated.
How do you sustain development?
Chart.ts is built and maintained by developers who believe charting libraries should be free and open. We accept GitHub Sponsors for those who want to support the project.
Will there be a paid tier in the future?
The core library will always be free and MIT licensed. If we ever offer paid services, they would be for hosting, support, or premium tooling, never for library features.
