Slite alternatives: 3 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.
A full team wiki with good search and enough knobs to justify Docker.
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 SliteIt is a flexible wiki, but Slite is easier to adopt and offers more polished hosted search, AI answers and knowledge-maintenance features with no server administration.
setupYou must provision a database and persistent volumes, then configure backups and a TLS reverse proxy for public use

A clean collaborative wiki with spaces, comments, history and search.
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 SliteIt covers collaborative pages well but does not match Slite's mature AI answers, document verification and managed team knowledge workflow without self-hosting work.
setupSelf-hosting requires Docker, a strong APP_SECRET, database credentials, persistent volumes, and normally a domain, TLS reverse proxy, and SMTP

Simple team documentation with rigid shelves and no per-seat toll.
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 SliteIt lacks Slite's hosted zero-admin experience and polished AI-assisted answers, document verification and knowledge-maintenance workflow, while imposing a rigid hierarchy.
setupThe official script expects a fresh Ubuntu host; manual installs require PHP extensions, a database, writable storage, mail, and TLS

People still pay for Slite because people keep paying when the note system is trusted across every device and disappears into their daily capture habits. The recurring cost buys file watching, conflict handling, indexing, mobile apps, encryption, backups, and migrations, not just the visible interface. If none of that applies to you, any pick above saves $120 a year.
Is there a free alternative to Slite?
Yes: Wiki.js, Docmost, BookStack. 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 Slite?
Our verdict is PARCIAL. The core loop is buildable, but a dependable replacement becomes a real weekend or multi-day project. For Slite, create a clean team wiki with documents, collections, search, and lightweight answers. The hard boundary is team search, permissions, integrations, ai answers, and polished collaborative editing, plus sync, collaboration, and capture polish. If you'd rather build, the exact one-shot prompt is free at puedovibecodearlo.app/slite.
