What does Cellystial do?

Cellystial is a template-based, API-first platform for generating pixel-perfect PDF documents — invoices, receipts, contracts, certificates, and more. Instead of wrestling with headless browsers or complex rendering libraries, you design a template once in a drag-and-drop editor, then send a JSON payload to a single API endpoint. The platform returns a ready-to-use PDF buffer in milliseconds, with no Chromium overhead or slow rendering times.

The workflow is straightforward: build a template visually using the drag-and-drop builder (no coding required), then call the REST API with your data. Cellystial handles the rest — tables, images, charts, and dynamic fields all render accurately. For high-volume needs, the batch generation feature lets you produce thousands of documents in one request. The platform also offers cloud storage for generated PDFs, automatic email delivery, and password protection for sensitive documents. Integrations with Zapier, Make, and n8n let you connect Cellystial to your existing tools without writing code.

Cellystial is built for developers and teams who need reliable, scalable document generation. It's a good fit for SaaS companies generating invoices or receipts, legal teams producing standardized contracts, event organizers creating tickets, and HR departments issuing payslips or certificates. The free tier gives you 100 credits per month with no credit card required, making it easy to test before committing.
