It costs nothing because it leverages our highly optimized managed ClickHouse cluster hosted in Europe, or your own data warehouse infrastructure where you maintain complete control over your data. The free option helps spread the word about d8a.tech, while we focus our monetization on high-traffic accounts and Enterprise features.

Fair usage depends on how you use d8a.tech. If you use the embedded analytics dashboard, the free tier includes up to 500k events per month. Larger embedded analytics volumes remain affordable: for example, 10M events per month can cost less than $100. If you use d8a.tech as a data collection service for your own warehouse, the fair usage threshold is 30M events per month. Above that level, we ask teams to move to a paid plan so we can protect the shared pipeline and keep improving the product.
