QuickChart is an open-source chart image API operated by Alioth LLC. Its core function is rendering Chart.js configurations into image URLs that can be embedded directly. It is well suited to scenarios where running a frontend charting library is inconvenient, such as emails, PDFs, reports, websites, and chat messages. It also provides a QR code API. According to the official site, it has rendered more than 4 billion images.
QuickChart’s biggest advantage is that it is based on Chart.js, so users do not need to learn a new proprietary chart format. The API accepts Chart.js configurations via https://quickchart.io/chart?c=... and supports parameters such as width and height, background, Chart.js version, encoding method, and output format. It can output PNG, WebP, JPG, SVG, PDF, and base64. QuickChart provides examples and client libraries for JavaScript, Python, C#, Java, Ruby, PHP, and Go, but in practice it can be used with any language capable of constructing a URL. On the no-code side, it offers Chart Maker and integrations with Zapier, Make, Airtable, Google Sheets, Salesforce, Bubble, AppSheet, and more, making it suitable for automated reporting and marketing workflows.
The product uses a dual-license model: GNU AGPLv3 and a commercial license. Generated images can be used for any purpose, but if you want to commercially modify the source code or use it privately/on-prem, you need to purchase a license. In terms of pricing, the Community plan is free and supports charts and QR codes, but comes with rate limits, shared servers, and best-effort email support. The Professional plan costs $40/month and includes 100,000 images/month, 50,000 short URLs/month, low latency, short links, custom plugins, and priority support. Enterprise pricing requires contacting sales and offers no rate limits, unlimited charts, dedicated clusters, a global CDN, custom fonts/backgrounds/domains, on-prem deployment, and SLA. Payments are supported via Stripe credit card and PayPal.
Its main advantage is extremely lightweight integration: a single URL can be used in emails, PDFs, and HTML. Its open-source nature and Chart.js ecosystem also reduce lock-in risk. The documentation covers API parameters, client libraries, QR codes, and multi-platform integration tutorials, and is generally high quality. The downsides are that complex charts still depend on your ability to configure Chart.js; the free tier has rate and latency limits; and enterprise-grade compliance, private deployment, and SLA require a paid plan.
QuickChart is suitable for developers, growth/marketing teams, no-code users, and business applications that need to generate email reports, QR codes, or static charts at scale. It is less suitable for scenarios that only need interactive frontend charts. The collected information does not include details about access from mainland China, ICP filing, node locations, or RMB payment support, so its China accessibility should be considered unknown. If access stability is critical, you can evaluate Enterprise/on-prem options or self-host QuickChart, combined with domestic cloud resources as an alternative deployment approach.
