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! 🙌
