Hey Product Hunt 👋 I'm Hugo, the maker of Signatra. The problem: Every time I needed to sign a contract or invoice, I had two bad options — pay €15-25/month for DocuSign or Adobe Sign, or upload sensitive documents to some random "free" online tool. Both meant trusting a third party with private business documents. The fix: Signatra signs your PDFs entirely in your browser. Your files are loaded, signed, and downloaded without ever touching a server. We literally cannot see your documents, even if we wanted to. What's inside: 🔒 100% local PDF processing (powered by pdf-lib + pdf.js) ✍️ Drag-and-drop signature placement, resize anywhere on the page 📄 Sign single page or every page in a batch 💾 Save signatures for one-click reuse 🇪🇺 GDPR-compliant by design — Portugal-based, EU data controller Pricing that respects you: Free: 10 PDFs/day, no credit card Pro: €5/month — unlimited signing, unlimited saved signatures, all pages at once That's 3-5x cheaper than DocuSign with stronger privacy guarantees. Built solo with PHP + vanilla JS (no framework bloat). Zero VC money, zero tracking, zero document uploads. I'd love your feedback — especially from anyone tired of paying enterprise prices for a contract signature. Ask me anything! 🙌
