Self-hosting OpenProject for 100 people: the cost

At 100 users, OpenProject needs 8.1 GB of memory and 45 GB of disk. That fits the Basic 16 GiB at DigitalOcean for $96.00 a month. Add backups and the time it takes to look after and the real figure is $340 a month.

How 8.1 GB was arrived at

4 GB covers the stack at rest, every container the project ships included. 100 users at 25 MB each adds 2.4 GB, giving 6.4 GB. Adding 25% headroom so the machine is not run at its ceiling gives 8.1 GB, and the smallest plan at or above that is the Basic 16 GiB with 16 GB.

Disk works the same way: 25 GB to begin with, plus 0.2 GB per user, so 45 GB against the 320 GB the plan includes.

Rails monolith with PostgreSQL and Memcached. Carries classical project management, including baselines and earned value, which the newer tools omit.

If you do not price your own time, the 36-month figure is $4,147 instead. Both numbers are real; which one applies depends on whether the hours would otherwise have been billable.

Where to put OpenProject

8.1 GB of memory and 45 GB of disk is what this needs at 100 people. The cheapest plan that fits, among the providers whose prices we have read ourselves, is the Basic 16 GiB at DigitalOcean for $96.00 a month.

We are not claiming this is the cheapest server on the internet. It is the cheapest one we can honestly quote. Hetzner Cloud, Vultr and PikaPods publish prices we could not read programmatically, and Hetzner in particular is usually cheaper per gigabyte of memory than anything quoted above. Price them yourself before you commit.

The DigitalOcean link above is a referral link: if you sign up through it and pay your first $25, we receive $25 of DigitalOcean account credit. That never changes the computed costs, which server is chosen, or the conclusion of this page. The sizing model and every price source are published in full.
