QuickChart Barcode Alternative: Specialist Barcode API

QuickChart is an excellent chart-rendering service that also exposes QR and barcode endpoints; BarGen is a barcode specialist.

Choose BarGen when barcodes are the product: GS1-128 and GS1 DataMatrix with Application Identifier validation, EPS and PDF vector output for print, 25 formats, and a 99.9% SLA on the Business plan.

Choose QuickChart when charts are the product and barcodes are a side need - its free Community tier (10,000 images/month under AGPL, as of August 2026) is generous for that.

BarGen plans: free with 1,000 calls/month, Pro $29/month for 10,000, Business $79/month for 100,000.

QuickChart deserves its popularity. It renders Chart.js configurations as images, has a free Community tier of 10,000 images per month under an AGPL licence, a Professional tier at €39/month with unlimited rendering, and it is open source and self-hostable (facts as of August 2026, from quickchart.io/pricing). Its QR endpoint is widely used, and it exposes barcode generation too.

The difference is centre of gravity. In a chart-first service, barcodes are a utility endpoint. In BarGen, they are the entire product: GS1 element strings are validated against Application Identifier rules before rendering, EPS and PDF vector output exists because print pipelines need it, and format-specific options (ECC levels, module scale, human-readable text control) are documented per symbology - all 25 of them, each with its own landing page and live sample.

A fair self-assessment: if you mostly need charts, or you want unlimited free volume and AGPL self-hosting fits your stack, QuickChart is the pragmatic pick - its free image quota is larger than BarGen's free API quota. If a wrong barcode is a failed shipment or a rejected GS1 audit, a specialist API is the safer dependency.

When QuickChart is the better choice

  • Your primary need is chart rendering - that is QuickChart's core product and it is very good at it.
  • You want a large free quota (10,000 images/month) or unlimited flat-fee volume at €39/month.
  • You want to self-host an AGPL-licensed renderer inside your own infrastructure.

Frequently asked questions

QuickChart's free tier is bigger than BarGen's. Why pay for BarGen?

If simple QR codes at volume are all you need, QuickChart's free tier is genuinely a good deal. BarGen's value is correctness and print-readiness for professional barcode work: GS1 Application Identifier validation, EPS/PDF vector output, per-format documentation, and an SLA-backed service - the things that matter when a barcode failure costs real money.

Does BarGen validate GS1 barcodes?

Yes. GS1-128 and GS1 DataMatrix element strings are checked against GS1 Application Identifier rules before rendering, and malformed input is rejected with a specific error message rather than silently producing a non-compliant label.

Can I self-host BarGen like QuickChart?

No, BarGen is a managed API only. If AGPL self-hosting is a hard requirement, QuickChart is the better fit; BarGen's trade-off is a managed service with an uptime SLA instead.

How fast is BarGen compared to QuickChart?

We only publish our own numbers: median server-side render time is 0.2 ms for Code 128, 0.3 ms for EAN-13 and GS1-128, 1.6 ms for DataMatrix and 7 ms for QR codes (200-run medians on production hardware, August 2026). End-to-end latency for both services is dominated by the network.
