What is LinShare?

LinShare is an open-source file sharing platform built for organizations that need to exchange documents with internal and external collaborators while keeping full control over privacy and traceability. It replaces email attachments, USB sticks and consumer cloud drives with a self-hosted service you run on your own infrastructure.

Key features

• Personal space – upload, version and organize your files, then share them by link or email.
• Shared spaces – workgroups with roles, nested folders and shared drives for teams.
• Upload requests – ask external people to send you files through a secure, expiring drop box.
• Guests – invite external users with restricted, time-limited accounts.
• Contact lists – reuse groups of recipients for recurring shares.
• Activity logs and audit – every download, share and change is traced.
• Enterprise integration – LDAP directories, LemonLDAP::NG and Microsoft Azure SSO (OpenID Connect), JWT, antivirus scanning, file previews.
• REST API – automate everything from your own tools.
• AI assistants – an MCP server lets any MCP-compatible assistant manage files, shares, guests and workgroups on your behalf.

What's new

LinShare 6.5.4 (July 2026):

• Guest accounts can now share through contact lists. When no list is assigned to the guest, the public contact lists of its source domain become usable as recipients.
• Fixed an anonymous share error when a restricted guest shares through a contact list.
• Upgrading from 6.5.3: follow the upgrade guide.

Full release notes for every version, with per-component changelogs, are in CHANGELOG.md.

Try it

Live demo

A public instance running the latest LinShare release is available at https://demo.linshare.org/. It is reset and updated on a regular basis.

Run it locally with Docker

The linshare-docker repository ships a docker-compose stack with the server, both web interfaces, PostgreSQL, MongoDB, a sample LDAP directory, ClamAV, a thumbnail server and a test SMTP relay:

git clone https://github.com/linagora/linshare-docker.git
cd linshare-docker
docker-compose up -d

Then open https://linshare.local (see the repository README for the /etc/hosts entries).

Install

For a production deployment, start with the compatibility matrix and pick the guide for your distribution.

Release packages (WAR files, UI bundles, SQL scripts) are published at http://download.linshare.org/versions/. You can also fetch every component of a release with Maven from this repository:

mvn dependency:copy-dependencies -DoutputDirectory='linshare'

Documentation

All user-facing documentation lives in this repository under documentation/.

The French translation sometimes lags behind English. Contributions to the FR tree are welcome.

Components and repositories

LinShare is split into several components, each in its own repository. This repository is the meta repository: it holds the documentation, the EPIC and user-story specifications, and a Maven aggregator (pom.xml) that pins the version of every component for a release.

• Found a security issue? Please follow SECURITY.md instead of opening a public issue.
• Setting up a development environment: see the developer guide.
