Does ChartQuery support the same barcode formats as Labelary?+
ChartQuery supports the most common barcode formats including Code 128, EAN-13, UPC-A, and QR codes. Labelary has broader barcode coverage with 35 symbologies including stacked barcodes (PDF417), Aztec Code, Data Matrix, and specialized formats like MaxiCode and Swiss QR. If you need niche barcode formats, Labelary has the edge. If you need barcodes plus charts, diagrams, AI, and labels, ChartQuery is the better choice.
Can I use ChartQuery as a drop-in replacement for Labelary?+
Not directly. Labelary uses a query-parameter GET API while ChartQuery uses a JSON POST API. The migration involves switching from URL parameters to JSON payloads, which is straightforward. For the barcode formats ChartQuery supports, the switch typically takes minutes per integration.
Does Labelary support charts or diagrams?+
No. Labelary is exclusively a barcode generation API. It does not support any type of chart, diagram, or non-barcode visualization. If you need both barcodes and charts in your workflow, ChartQuery covers both from a single API.
How does pricing compare for barcode-heavy workloads?+
Labelary Basic costs $44/month for 1,000 barcodes per day (~30,000/month). ChartQuery Starter costs $49/month for 750,000 credits (~150,000 barcode renders), which is significantly more volume. However, ChartQuery's credits also work across charts, diagrams, AI generation, and labels.
Is there a free tier?+
Yes. ChartQuery offers a free tier with 60 requests per hour per IP, no API key required. All five APIs (charts, diagrams, AI generation, barcodes, labels) are available with a watermark. Labelary also has a free trial with watermarks, limited to 100 barcodes per day.
Where is ChartQuery hosted?+
ChartQuery infrastructure is hosted entirely within the European Union. All data processing happens in the EU and no data leaves EU borders, making it fully GDPR compliant by design. Labelary does not publicly disclose its hosting location or GDPR compliance status.
