Confluence alternatives: 4 free & open-source picks
Curated, verified, and actually free. No trials, no crippled tiers. Star counts and last-activity dates checked by hand, not scraped and forgotten.
Una wiki moderna con suficientes controles para recordarte que ahora tú eres el administrador
licenseAGPL-3.0
runsyour server
installDocker Compose with PostgreSQL, or a Node.js package plus a supported database
dataPages, users, authentication data, and history in the configured database; optional storage modules can mirror content and assets to Git, local disk, or cloud storage
the catch vs ConfluenceIt lacks Confluence's mature enterprise templates, macros, whiteboards, marketplace and Atlassian integrations, while shifting hosting and upgrades to you.
setupYou must provision a database and persistent volumes, then configure backups and a TLS reverse proxy for public use

Confluence con menos ceremonia y una factura de Docker
licenseAGPL-3.0
runsyour machine or their cloud
installHosted signup or Docker Compose with PostgreSQL and Redis
dataPages, users, comments, and history in PostgreSQL; jobs/cache in Redis; attachments in a persistent local volume by default or S3/Azure Blob
the catch vs ConfluenceIt is simpler and faster, but has fewer enterprise macros, workflow controls, templates, marketplace integrations and Jira-native connections than Confluence.
setupSelf-hosting requires Docker, a strong APP_SECRET, database credentials, persistent volumes, and normally a domain, TLS reverse proxy, and SMTP

Una wiki organizada como una estantería; gloriosamente dogmática y mucho menos flexible que Confluence
licenseMIT
runsyour server
installFresh Ubuntu install script or manual PHP/MySQL setup
dataPages, users, permissions, and settings in MySQL/MariaDB; uploaded images and files in the server filesystem or configured object storage
the catch vs ConfluenceIts compulsory shelf/book/chapter structure and smaller extension surface are far less flexible than Confluence spaces, macros, databases, whiteboards and Jira-connected workflows.
setupThe official script expects a fresh Ubuntu host; manual installs require PHP extensions, a database, writable storage, mail, and TLS

El primo de código abierto ya crecido de Confluence; lo suficientemente potente como para requerir un administrador de verdad
licenseLGPL-2.1
runsyour server
installOfficial Docker Compose stack, Debian package, or Java application-server distribution
dataWiki documents, objects, users, metadata, and usually attachments in a relational database; configuration, extensions, caches, and optional attachment files in the permanent directory
the catch vs ConfluenceIt can approach Confluence's depth, but doing so carries a much heavier Java/Solr/database administration burden and less seamless Atlassian ecosystem integration.
setupThe production setup is a heavyweight Java service with a database, permanent storage, Solr, backups, and TLS to administer

OutlineA favourite self-hosted wiki recommendation; on-prem now starts at $10 a month and cloud is a 30-day trial

Los equipos pagan porque el estado compartido, las notificaciones, los permisos y las migraciones son más difíciles que la tabla o lista visible.
Is there a free alternative to Confluence?
Yes: Wiki.js, Docmost, BookStack and 1 more. Every tool on this page is either open source or genuinely free to use long-term: no trials, no crippled tiers.
Should I just build my own Confluence?
Our verdict is NO TANTO. No confundas la interfaz con el producto. El valor duradero de Confluence es la colaboración, las integraciones y el pulido, que una reconstrucción individual de una sola sesión no puede reproducir de manera responsable. Por eso, esta instrucción construye solo la herramienta personal de consuelo más honesta y cercana. If you'd rather build, the exact one-shot prompt is free at puedovibecodearlo.app/confluence.
