QuickChart alternative: when Cofferdock makes sense (and when it doesn't)

Pricing
| QuickChart | Cofferdock | |
|---|---|---|
| Free | Community plan: 10,000 charts a month, with rate limits and an AGPL licence | 50 credits a month |
| Paid | Professional: €39 a month, unlimited charts | Pro €9 (500 credits), Business €29 (2,000), Scale €79 (10,000) |
| Enterprise | Custom | Custom |
Where QuickChart wins
- If you only make charts, its free plan is very generous. 10,000 charts a month for free is a lot.
- Unlimited for €39. If you generate thousands of charts a month, its Professional plan is hard to beat.
- The full power of Chart.js, with very fine-grained customisation, plus a URL shortener for charts.
If all you need is charts, and lots of them, QuickChart is the logical choice.
Where Cofferdock wins
- It isn't just charts. The same credits give you HTML to image, HTML to PDF, website screenshots, QR codes, PDF editing, image conversion, zips and validation. If your workflow creates a chart and then puts it into a PDF that you email, you do it all with one account.
- Simpler to send. You give it labels and number series in a short JSON (
type,labels,series), without learning the full Chart.js configuration. - Output ready for n8n, Make and Zapier: the image itself, base64 or a temporary link.
- Servers in the European Union, and nothing you send is stored.
An example call on Cofferdock
{
"type": "bar",
"labels": ["Jan", "Feb", "Mar"],
"series": [{ "name": "Sales", "data": [120, 90, 150] }],
"output": "binary"
}Send it with POST to https://api.cofferdock.com/chart with your key in the x-api-key header. There's a recipe for n8n, and every other option is in the API reference.
In short
- Charts only, lots of them, with heavy customisation: QuickChart.
- Charts alongside other tasks (PDFs, images, screenshots, validation) or something simple to set up: Cofferdock.
You can try Cofferdock on the free plan, no card needed.
