Self-host vs Mixpanel

Example values: replace every number with your own. None of them is vendor data.

Self-hosting saves about $780 a year for 20 seats: SaaS $2,400 vs self-host $1,620 (server $144, backups $36, admin time $1,440). Break-even at about 14 seats at these numbers.

Admin hours start from our guess for difficulty unrated and are yours to edit. Mixpanel price: $0 a month flat (Growth plan). No per-seat price. Usage-based (events), seats unlimited on all plans: Free $0 (1M events/mo); Growth from $0, 1.5M events $100/mo billed annually ($140 monthly). Source: vendor pricing page, checked 2026-11-10.
