DocuSign killer for freelancers, but DocuSign/PandaDoc already own this space.

Strengths
  • •No-account signer flow removes friction that competitors require
  • •Server-side PDF stamping + cryptographic verification on every signature
  • •12 free PDF tools bundled in, differentiating beyond signing alone
Weaknesses
  • •E-signature market is crowded (HelloSign, Adobe Sign, PandaDoc); free tier doesn't guarantee adoption
  • •Unclear how legal enforceability compares internationally or survives court challenge

Post Description

Hey HN, I built SignForge as a free alternative to DocuSign/PandaDoc for freelancers and small businesses who just need to get documents signed without the $30/month tax.

How it works: Upload a PDF → drag signature/date/text fields onto it → send to signer via email → they sign with a link (no account needed) → you get the signed PDF with a full audit trail and verification certificate.

Tech stack: Next.js + FastAPI + PostgreSQL + PyMuPDF. PDFs are stamped server-side (image overlay, not AcroForm) so it works reliably on any PDF. Every signed document gets a QR code and cryptographic verification so you can prove it wasn't tampered with.

Also built 12 free PDF tools (merge, split, compress, watermark, etc.) that run entirely on the server with no file storage — processed and returned immediately.

Would love feedback on the signing UX and what features matter most for your use case.

ProofPudding – Document Extraction API with Citations (PDF/Docx)

ProofPudding returns extraction results with explicit links back to the exact page and source text, supports native and scanned PDFs plus DOCX/images, and ships Python/TypeScript SDKs — handy for agents that need auditable facts. It’s a pragmatic product (per-extraction pricing and confidence scores are nice), but the market is crowded; I want clarity on underlying models, real-world accuracy numbers, and how it compares to Document AI/Textract in edge cases.
