Documents and notes decision
DocHub
A basic PDF upload/annotate/sign workflow is realistic for a single developer in about a week, but matching DocHub’s compliance, scale, ecosystem integrations, and polished UX would be expensive and slow to reproduce.

Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need — the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship.
What a replacement has to do
- Upload a document, render/edit pages in-browser, add/place signature fields, send a shareable link or email to recipients, and store the signed result with an audit trail.
What it still won’t have
- Enterprise compliance certifications (SOC 2, HIPAA, PCI DSS)
- Polished, battle-tested UI and large-scale reliability
- Deep Google Workspace and cloud-storage integrations
- Document-level audit/evidence provided by vendor
What remains hard
- Compliance and regulation
DocHub complies with industry-leading standards, regulations, and certifications to ensure the most effective and secure workflows.

The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a minimal self-hosted PDF signing web app using Node.js (Express), PostgreSQL for metadata, AWS S3 for file storage, and a React frontend. Core features in scope: file upload (max 31 MB), in-browser PDF rendering and simple annotations using PDF.js, create/place signature/initial fields, capture signature input (draw/typed/upload), send signer emails with a per-document shareable secure link, record a simple audit trail (who/when/action), and export a flattened signed PDF. Out of scope: mobile native apps, SOC2/HIPAA certification, enterprise SSO, and deep third-party integrations. Include server-side validation, input sanitization, error handling, and unit tests for upload, signing workflow, and export endpoints.
How we checked
How the score was reached
- Partly verdict base52
- An open-source build was found+5
- 4 cited sources+3
- 3/3 assessment runs agreed+4
- Hard moats found in the evidence-3
- Evidence score61
The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time — so the same evidence always produces the same number.
