About QuickChart

QuickChart.io is a public API that serves millions of QR codes per month. There is a 60 requests per minute per IP rate limit (1 chart/sec) on the public service. If you'd like to exceed this limit, please purchase a license or contact us.

We're also open source, dual licensed under the GNU GPLv3 and a commercial license. You may use images produced by this website for any purpose. If you would like to modify QuickChart source code for commercial use, please purchase a license or contact us.

This service was built in response to the Google Image Charts shutdown. Don't use proprietary chart formats - choose open source!
