Self-hosting PostHog for 1 person: the cost
At 1 user, PostHog needs 10.0 GB of memory and 60.2 GB of disk. That fits the Starter 16 GB at VPSServer for $84.00 a month. Add backups and the time it takes to look after and the real figure is $326 a month.

How 10.0 GB was arrived at
8 GB covers the stack at rest, every container the project ships included. 1 user at 15 MB each adds 0.0 GB, giving 8.0 GB. Adding 25% headroom so the machine is not run at its ceiling gives 10.0 GB, and the smallest plan at or above that is the Starter 16 GB with 16 GB.
Disk works the same way: 60 GB to begin with, plus 0.2 GB per user, so 60.2 GB against the 300 GB the plan includes.
Kafka, ClickHouse, PostgreSQL, Redis and several workers. PostHog itself now discourages self-hosting below a substantial scale, and the sizing here reflects that honestly.
Over three years
| Period | Server and backups | Your time | Total |
|---|---|---|---|
| Setup, once | — | $1,200 | $1,200 |
| Per month | $101 | $225 | $326 |
| First year | $1,210 | $3,900 | $5,110 |
| 36 months | $3,629 | $9,300 | $12,929 |
If you do not price your own time, the 36-month figure is $3,629 instead. Both numbers are real; which one applies depends on whether the hours would otherwise have been billable.
What you would be paying instead at this size
| Commercial product | Tier | Per month | Difference | |
|---|---|---|---|---|
| Mixpanel | Free | $0.00 | -$326 | breakdown |
| Amplitude | Free | $0.00 | -$326 | breakdown |
| Google Analytics 4 | Free | $0.00 | -$326 | breakdown |
A positive difference means self-hosting is cheaper at this size, with your time already counted.
Where to put PostHog
10.0 GB of memory and 60.2 GB of disk is what this needs at solo. The cheapest plan that fits, among the providers whose prices we have read ourselves, is the Starter 16 GB at VPSServer for $84.00 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.
