Self-hosted wiki software for teams
Stop paying per-seat for Notion or Confluence. Run a modern wiki on your own infrastructure and keep your data private.
Why teams run their own wiki
A self-hosted wiki is a knowledge base or documentation platform you run on your own servers or private cloud. No vendor lock-in. No surprise price increases. No outages taking down your team's docs.
Teams use wikis for internal documentation, API docs, onboarding guides, home lab records, or personal knowledge bases. Unlike SaaS (Notion, Confluence, Outline Cloud), self-hosted wikis put you in control of updates, backups, and who accesses what.
Who uses self-hosted wikis?
- Growing teams (10-100 people) moving away from per-seat SaaS pricing
- DevOps and engineering teams integrating wikis with Git, SSO, and monitoring stacks
- Home lab enthusiasts documenting networks and hardware setups
- Privacy-first organizations needing data residency in the EU or specific regions
The catch
Self-hosting saves money but costs time. You manage OS updates, database migrations, TLS certificates, backups, and disaster recovery. That is work. Opsily handles it for you.

The real cost of DIY self-hosting
Maintenance is a second job. OS updates, database migrations, TLS cert renewals, backups, disaster recovery. Reddit users call it a 'second job keeping their wiki running'. Opsily eliminates that overhead.
