Decisions Log

2026-02-14 — Product: PDF API (approved by user)

Chose HTML/Markdown to PDF API over webhook relay and JSON schema validation. Fastest to ship, proven demand, clear monetization.

2026-02-14 — Name: DocFast

Product name "DocFast" — short, memorable, describes value prop (fast document generation). Domain TBD.

2026-02-14 — Tech Stack: TypeScript + Express + Puppeteer

TypeScript for type safety and fast iteration
Express for simplicity (no framework overhead)
Puppeteer for high-fidelity PDF rendering (Chrome-based = pixel-perfect)
Marked for markdown parsing
Chose Puppeteer over wkhtmltopdf/pdfkit for better CSS support and template rendering quality

2026-02-14 — Templates: Invoice + Receipt first

Built-in invoice and receipt templates as differentiator. Most PDF API competitors are raw converters — templates add immediate value for common use cases.

2026-02-14 — Pricing model (planned)

Free tier: 100 PDFs/month
Pro: $9/mo for 5,000 PDFs
Business: $29/mo for 25,000 PDFs
Enterprise: custom Not yet implemented — need Stripe integration.
