Self-hosted alternatives to Confluence, priced
3 open-source tools that can replace Confluence, each shown with what it would actually cost to run for a team of 10 people. Confluence on the Standard tier costs $0.00 a month at that size.
Start here
Confluence's Free plan covers teams of up to 10 users. Inside that limit there is no licence cost, so self-hosting a replacement saves nothing.
| Tool | Server only | With your time | vs Confluence | Operational weight | Licence |
|---|---|---|---|---|---|
| BookStack | $12.00 | $49.50 | -$1,932 | easy | MIT |
| Outline | $26.40 | $139 | -$5,450 | medium | source-available |
| Docmost | $26.40 | $139 | -$5,450 | medium | AGPL-3.0 |
The final column is the 36-month difference: positive means self-hosting is cheaper.
Which one to pick
BookStack 19,038 stars
Laravel and MySQL. The least demanding wiki on this list and the easiest to back up, because it is one database and one uploads directory.
At 10 people it needs 1.3 GB of memory and 12 GB of disk, which fits the Starter 2 GB at VPSServer for $10.00 a month. Setting it up is roughly 2 hours of work, then 0.5 hours a month to keep it healthy.

Outline 40,524 stars
Needs PostgreSQL, Redis and S3-compatible object storage for attachments. The object storage requirement is the part people miss when budgeting.
At 10 people it needs 2.6 GB of memory and 18 GB of disk, which fits the Starter 4 GB at VPSServer for $22.00 a month. Setting it up is roughly 6 hours of work, then 1.5 hours a month to keep it healthy.
