Mayan EDMS, OpenKM and Papra all let you self-host a searchable, tag-and-metadata-driven document store for free, but they aim at different scales of the same…
Open Source · From Free
Best for: Organizations that need enterprise-scale, multi-language OCR document management with a flexible metadata-and-cabinet model and no licensing fees, and have the Docker/Django skills to run it.
Freemium · From Free (Community Edition); Professional and Cloud plans are custom-quoted, with third-party estimates starting around $30/user/month
Best for: Compliance-heavy teams (legal, healthcare, government) that need formal records management and jBPM-based workflow automation, with the option to add vendor support via a paid edition.
Open Source · From Free (self-hosted); Cloud plans from $7.50/month billed annually
Best for: Individuals, freelancers and small teams who want a lightweight, easy self-hosted (or low-cost cloud) document archive with email ingestion and automatic tagging rather than a full enterprise DMS.

Enterprise scale and distributed OCR
Mayan EDMS is architected to scale from small deployments to repositories with hundreds of millions of documents, with OCR workloads that can be distributed across multiple worker nodes for large installs.
Mayan EDMS
Formal records management and workflow
OpenKM pairs a jBPM-based workflow engine with dedicated records management (RM) features for retention schedules and regulatory compliance, plus an optional paid Professional or Cloud edition with vendor support.
OpenKM
Lightweight footprint, fast to run
Papra ships as a Docker image under 200MB and is explicitly designed for people who found tools like Evernote or enterprise DMS platforms too complex, prioritizing simplicity over feature breadth.
Papra
Automated intake differs sharply
Papra automates document intake with a dedicated email-ingestion address and configurable auto-tagging rules, a workflow Mayan EDMS and OpenKM do not document as a built-in capability.
Papra
Both enterprise options add e-signature capability
Mayan EDMS verifies embedded cryptographic signatures and detached signature files, while OpenKM includes native digital signature support; Papra does not document e-signature functionality.

Papra is the lightest to operate, shipping as a Docker image under 200MB with a managed cloud option starting at $9/month ($7.50/month billed annually) for teams that don't want to self-host at all. Mayan EDMS and OpenKM require more Docker/Django or Java administration skill and have no first-party managed offering as accessible for small teams.
Yes. Mayan EDMS has a built-in workflow engine that tracks document state and triggers actions on changes, and OpenKM automates approval chains and business processes with a jBPM-based engine. Papra is focused on archiving and search rather than workflow automation.
OpenKM has dedicated records management (RM) features built for retention schedules and regulatory compliance, making it the strongest documented fit for legal, healthcare or government use cases among the three. Mayan EDMS supports electronic signature verification but does not document a dedicated RM module, and Papra does not document compliance certifications.
Mayan EDMS is explicitly architected to scale to repositories with hundreds of millions of documents, with OCR that can be distributed across multiple worker nodes. OpenKM scales from small teams to large enterprise deployments. Papra is a younger project (started 2025) built primarily for individuals and small teams.
Mayan EDMS is free and open source under Apache 2.0 with only optional paid consulting. OpenKM's Community Edition is free and open source, while its Professional and Cloud editions are paid and custom-quoted. Papra is free to self-host under AGPL-3.0, with an optional paid cloud tier starting at $7.50/month billed annually.
Mayan EDMS is the most established, founded in 2010 with over 200 releases and more than 100 contributors. OpenKM was founded in 2005 as a company. Papra is the newest of the three, started as a side project in January 2025.
