Umami 38,748 stars
Next.js application against PostgreSQL or MySQL. The lightest credible analytics stack: two containers and no separate column store.
At 10 people it needs 1.3 GB of memory and 10.5 GB of disk, which fits the CX23 (cost-optimized) at Hetzner Cloud for $6.70 a month. Setting it up is roughly 2 hours of work, then 0.5 hours a month to keep it healthy.

Plausible Analytics 29,036 stars
Ships as Elixir plus ClickHouse plus PostgreSQL. ClickHouse sets the memory floor, so this stack does not usefully shrink below 2 GB. Disk scales with pageviews rather than with seats.
At 10 people it needs 2.6 GB of memory and 21 GB of disk, which fits the CX23 (cost-optimized) at Hetzner Cloud for $6.70 a month. Setting it up is roughly 6 hours of work, then 1.5 hours a month to keep it healthy.
