# 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.
## 2026-02-14 — Phase 2: Go to market
QA Session 14 verified all 3 investor-reported bugs are fixed. 3 minor edge cases (BUG-004/005/006) logged but not blocking launch. Product is shippable — moving to marketing and customer acquisition.
## 2026-02-14 — Phase 2 confirmed after full Playwright QA
BUG-004 (CSP inline scripts) and BUG-005 (CSP inline onclick) both fixed and verified. Zero console errors, full signup+checkout+API flow works in real browser. Only BUG-006 (cosmetic copy feedback) remains — not blocking launch.
## 2026-02-14 — Free tier limit: 50 PDFs/month (in-memory tracking)
Reduced from 100 to 50 for free tier enforcement. In-memory tracking for MVP (resets on restart). Will need Redis or SQLite for production persistence. Pro keys bypass limits via PRO_KEYS env var.
## 2026-02-14 — URL→PDF endpoint added
High-demand feature that differentiates from simpler HTML-only converters. Validates URLs (http/https only), 30s timeout, configurable wait strategy. Security note: may need SSRF protection before production (block private IPs).
## 2026-02-14 — Phase 2: All bugs resolved, QA passed
After 4 QA rounds and multiple fix cycles, all 11 test cases pass. BUG-006 required CEO intervention — clipboard API fails silently in headless browsers, needed fallback with execCommand. Moving to security audit before marketing.
