The most-starred app in this category is not a document management system. Stirling PDF (90,427 stars) is a PDF Swiss army knife — merge, split, compress, convert, OCR — and it deliberately stores nothing. This category is really three shelves: PDF manipulation tools (Stirling PDF, Gotenberg, OCRmyPDF), e-signature platforms (Documenso, DocuSeal), and the searchable archive people usually mean by "going paperless," which is Paperless-ngx territory.
Ask what happens to a document after you touch it. If the answer is "I save it back to wherever it came from," you need a toolbox: Stirling PDF for interactive use, or Gotenberg's stateless API (12,936 stars) if software rather than humans will be doing the converting. If the answer is "someone needs to sign it," you want a signing platform with audit trails — Documenso (14,757 stars) and DocuSeal (18,380) both do legally binding signatures, templates, and webhooks; both are AGPL with some features held for paid tiers, so check the feature matrix against your needs before picking. If the answer is "it gets filed and I need to find it in 2029," you want an archive with OCR, tags, and full-text search. The second consideration is the OCR pipeline: OCRmyPDF (34,581 stars) is the engine that makes scanned paper searchable, and it's already embedded in the paperless workflows, so you rarely deploy it alone.
Stirling PDF is the easy first win: one container, 512 MB, Easy difficulty, and it immediately replaces every sketchy "free PDF converter" website your family uploads tax documents to. That privacy argument alone justifies the install. Documenso is the pick when contracts are the pain point — a transparent, self-hosted answer to DocuSign with a modern interface. And when the filing cabinet is the real enemy, Paperless-ngx plus a duplex scanner is the proven combination — budget a weekend for the initial setup and tagging scheme, then it runs itself.
The recurring disappointment in this category comes from installing Stirling PDF, or a file manager like Filestash, and expecting document management to emerge. Neither indexes contents, extracts dates, or answers "find the furnace invoice from March." Tools transform documents; an archive remembers them. You'll likely want one of each.
First install: Stirling PDF, because it's five minutes of effort and pays for itself weekly. First real project: Paperless-ngx, because a searchable archive is the thing this category is actually about.
