QuickChart

Open source chart image API that renders Chart.js configurations as images via URL or POST request

QuickChart is an HTTP API that generates chart images, QR codes, barcodes, word clouds, table images, and Graphviz graphs from API requests. Charts are defined using Chart.js configurations embedded in URLs or sent via POST, producing embeddable images usable in emails, reports, and no-code platforms. Client libraries are available for JavaScript, Python, Java, C#, Ruby, PHP, and Go. The service is open source, dual licensed under GNU AGPLv3 and a commercial license, and is developed by Alioth LLC, based in San Mateo, California.
