Questions & Answers

As answered by people managing Rendlet and PDFGate.

What makes your product unique?

Rendlet's answer

It converts HTML, or JSON plus a built-in template (invoice, itinerary), to PDF over one HTTP endpoint (POST /v1/pdf). Authentication is by API key.

PDFGate's answer:

PDFGate covers the whole document workflow in one API. You can generate PDFs from HTML or URLs, add and fill native form fields, extract form data, and send documents for digital signature without stitching several vendors together.

Why should a person choose your product over its competitors?

Rendlet's answer

The free plan includes 100 documents a month, up to 10 pages each, with no watermark. A sandbox key allows a few watermarked test renders a day without signup.

Paid plans are $7, $19, and $59 a month for 1,000, 5,000, and 25,000 documents. Caps are hard. There is no overage billing. At the cap the API returns 429 until you upgrade or the next month.

PDFGate's answer:

Most HTML to PDF APIs stop once the PDF is rendered. PDFGate goes further, with fillable form fields, flattening, watermarking, password protection, compression and signing envelopes with webhooks. It also ships an MCP server, so AI agents can generate and manage PDFs directly.

How would you describe the primary audience of your product?

Rendlet's answer

Developers, and AI agents, that need HTML or JSON plus a built-in template (invoice, itinerary) turned into a PDF over one HTTP endpoint.

PDFGate's answer:

Developers and SaaS teams that generate invoices, contracts, reports and forms from their own backend, and businesses that need those documents filled and signed.

Which are the primary technologies used for building your product?

Rendlet's answer

HTTP API with API-key authentication (POST /v1/pdf). An OpenAPI 3.1 spec is at https://rendlet.com/openapi.json. A remote MCP server is at https://rendlet.com/mcp. Noto Sans SC is built in for Chinese text. Agents can request response:base64.

PDFGate's answer:

PDFGate’s REST API is built with Node.js and NestJS, which handle document generation, form fields and webhooks. Digital signing runs as a separate Java service, chosen for its mature cryptography and PDF signing libraries. The platform is hosted on AWS. Developers can integrate through the REST API or through the PDFGate MCP server, which lets AI agents work with PDFs directly.
