Documents and notes decision
Xodo Pro
A competent developer can build a narrow self-hosted PDF editor + basic e-sign flow, but reproducing Xodo's audited compliance, Apryse SDK quality, and cross-platform polished apps is difficult—so build for limited internal use, keep paying for enterprise-grade needs.

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 PDF → render & edit pages → annotate/annotate/save → export/convert or request e-signature and produce signed PDF.
What it still won’t have
- SOC 2 compliance and related audited data-protection controls
- Apryse PDF SDK's proprietary robustness and edge-case PDF rendering/processing
- Cross-platform polished desktop/mobile apps and bundled enterprise support
- High-quality built-in OCR/AI PDF summarization (if relying on proprietary services)
What remains hard
- Compliance and regulation
Close deals faster with secure, legally binding e-signatures. Finalize agreements with online document signing, full audit trails, and SOC 2 compliant data protection.
- Brand trust
Backed by Apryse's 20 years of PDF technology and expertise, Xodo delivers reliable document tools built on the same SDK trusted by enterprise developers worldwide.

Runnable build prompt
Build a minimal self-hosted PDF web service with Node.js/Express backend, Postgres DB, S3-compatible file storage, and a React frontend. In scope: file upload/download, PDF viewing via PDF.js, basic annotate (sticky notes, highlights, freehand) persisted to Postgres, export/convert PDF→JPEG and basic PDF merging/splitting using open-source CLI tools (e.g., qpdf or pdfcpu), a simple e-sign flow (capture signature image, flatten into PDF, and store an audit record), user auth (email+password) and a paid-subscription flag to gate premium features. Out of scope: SOC 2 compliance, multi-platform native desktop/mobile apps, enterprise-grade OCR/AI summarization. Include error handling, input validation, background worker for conversions, and unit/integration tests for upload, annotation persistence, conversion, and signing paths.

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.
