Paperless-ngx vs Docspell: Document Management Compared

If you’re drowning in paper receipts, tax forms, and warranty PDFs scattered across folders, both Paperless-ngx and Docspell promise to fix that with OCR, tagging, and full-text search. But they take fundamentally different approaches to the problem — and picking the wrong one means migrating thousands of documents later.

Quick Verdict

Paperless-ngx is the better choice for most self-hosters. It has a larger community, simpler setup, better mobile experience, and more polished UI. Docspell targets users who need multi-user workspaces, email integration, and a task-based document workflow — but comes with a heavier stack and steeper learning curve.

Overview

Paperless-ngx is the community fork of the original Paperless project. It ingests documents via a consumption directory, web upload, or mobile app, runs Tesseract OCR, and organizes everything with tags, correspondents, document types, and storage paths. It’s the most popular self-hosted DMS by a wide margin.

Docspell is a personal document organizer built in Scala. It splits into two components — a REST server for the web UI and a job executor (joex) for background processing. Docspell adds features like collective (multi-user) workspaces, email attachment import, and Apache Solr for full-text search.

Feature Comparison

Feature	Paperless-ngx	Docspell
OCR engine	Tesseract (built-in)	Tesseract (built-in)
Full-text search	Built-in (Whoosh or Tika)	Apache Solr (external)
Multi-user	Basic (single user + permissions)	Yes (collectives with shared access)
Email import	No (consumption folder only)	Yes (IMAP polling + attachment extraction)
Mobile app	Yes (official Android/iOS apps)	No (responsive web UI only)
Auto-tagging	Yes (ML-based suggestions)	Yes (learn from user corrections)
Correspondent detection	Yes (automatic extraction)	Yes (sender/recipient detection)
API	REST API	REST API
Docker services	3 (app + Redis + PostgreSQL)	5 (restserver + joex + PostgreSQL + Solr + consumedir)
Programming language	Python (Django)	Scala (JVM)
License	GPL-3.0	AGPL-3.0
GitHub stars	24,000+	1,600+

Installation Complexity

Paperless-ngx deploys with three containers: the app, Redis, and PostgreSQL. Configuration is straightforward with environment variables. The consumption folder watches for new files and processes them automatically.

# Paperless-ngx: 3 services
services:
  webserver:
    image: ghcr.io/paperless-ngx/paperless-ngx:2.20.11
  redis:
    image: redis:7-alpine
  db:
    image: postgres:16-alpine

Docspell requires five services: the REST server, job executor (joex), PostgreSQL, Apache Solr, and optionally a consumedir watcher. The configuration uses a Scala-specific environment variable naming convention where dots become underscores and dashes become double underscores — which trips up most newcomers.

# Docspell: 5 services
services:
  restserver:
    image: ghcr.io/docspell/restserver:v0.43.0
  joex:
    image: ghcr.io/docspell/joex:v0.43.0
  db:
    image: postgres:16-alpine
  solr:
    image: solr:10
  consumedir:
    image: docspell/dsc:v0.11.0

Paperless-ngx wins on setup simplicity. Docspell’s split architecture and Solr dependency add operational overhead.

Performance and Resource Usage

Resource	Paperless-ngx	Docspell
RAM (idle)	~300-400 MB	~800-1,200 MB
RAM (processing)	~600-900 MB	~1,500-2,500 MB
CPU during OCR	High (Tesseract)	High (Tesseract + JVM)
Disk (application)	~1.5 GB	~2.5 GB
Minimum RAM	2 GB	4 GB

Docspell’s JVM-based architecture and Solr search index consume significantly more memory. The joex worker can spike during document processing. Paperless-ngx runs lighter because Python’s memory footprint is smaller than the JVM, and its built-in search doesn’t require a separate service.

Community and Support

Paperless-ngx has a massive community. Over 24,000 GitHub stars, 500+ contributors, active Discord, and frequent releases (multiple per month). Documentation is thorough with a dedicated docs site. Most self-hosting communities recommend it as the default DMS.

Docspell has ~1,600 GitHub stars and is primarily maintained by a single developer. Documentation is good but the community is small. Releases happen every few months. Support is mainly through GitHub issues.

Use Cases

Choose Paperless-ngx If…

• You want the easiest setup and most polished experience
• You’re a single user or household managing personal documents
• You want mobile apps for scanning documents on the go
• You prefer a large community with frequent updates
• You’re running on limited hardware (2 GB RAM minimum)

Choose Docspell If…

• You need multi-user workspaces (e.g., a small office with shared documents)
• You want email import — Docspell polls IMAP mailboxes and extracts attachments automatically
• You need the full-text search power of Apache Solr
• You’re comfortable managing a 5-service Docker stack
• You have 4+ GB of RAM available

Final Verdict

For most self-hosters managing personal or household documents, Paperless-ngx is the right tool. It’s easier to deploy, lighter on resources, has better mobile support, and benefits from a community 15x larger than Docspell’s. The ML-based auto-tagging and correspondent detection work well out of the box.

Docspell carves out a niche for users who need collaborative document management or IMAP email integration. If your workflow involves shared document access across multiple users or automatically ingesting email attachments, Docspell’s architecture supports that natively. But that power comes at the cost of a heavier stack and more complex configuration.

FAQ

Can Paperless-ngx handle multi-user setups?

It supports basic authentication and permissions, but it’s designed as a single-user system. Multiple users can log in, but there’s no concept of separate workspaces or collectives like Docspell offers.

Does Docspell have a mobile app?

No. Docspell’s web UI is responsive and works on mobile browsers, but there’s no native app for scanning and uploading documents.

Can I migrate between the two?

Both store original files on disk and metadata in PostgreSQL, but they use different schemas. Migration requires exporting documents and re-importing them — there’s no direct migration path.

Which is better for OCR accuracy?

Both use Tesseract, so OCR accuracy is identical. The difference is in post-processing: Paperless-ngx uses ML to suggest tags and correspondents, while Docspell learns from your manual corrections over time.
