GCP self-host breakdown
Add ~10% buffer for sustained spikes. Self-host pays off on ~3M+ events/month, especially in the EU where SaaS charges add up.
When each makes sense
- Stape — fastest setup, best for stores 100K – 2M events/month. EU users get Frankfurt by default.
- Addingwell — EU-data-residency baked in (great for GDPR-anxious clients), good UI for non-engineers.
- Self-host on GCP — full control, lowest unit cost above 3M events, but you own ops + uptime + monitoring.
