Funnels & user journeys
Funnels are why teams adopt Amplitude, but the chart performance and per-tier feature gating turn a daily PM tool into a quarterly Finance debate.
What people actually say
✕Charts hit hard limits at scale — Event Segmentation only renders 365 days of daily granularity, inline behavioural cohorts cap at three years, and date ranges beyond three years return a 404.
Source: Amplitude docs, Limits ↗✕Plus is limited to a small number of saved behavioural cohorts per org — unlimited cohorts and advanced behavioural analysis only unlock on Growth and above.
Source: Amplitude pricing page ↗✕Userpilot's review notes the pricing structure gets steep as data and usage grow, with advanced capabilities locked behind expensive plans — making the everyday funnel a tier negotiation.

Funnels are parameterised SQL against your Postgres event table, cached in Redis and rendered by a small Next.js dashboard. ClickHouse slots in when volume justifies it. No 365-day chart cap, no behavioural-cohort SKU, no Plus-tier feature gate — just the query.
