How pricing works
These two tools don't price the same way, so the headline numbers below aren't directly comparable until you plug in your own volume.
- Amplitude (Unknown model) — Amplitude bills on a fixed plan from $49/mo, so the listed price is what you pay regardless of volume.
- Sonar (Perplexity) (Per Usage) — Sonar (Perplexity) bills purely on usage. There is no fixed per-seat fee, so the monthly cost depends entirely on how much you consume.
Per-minute, per-credit and per-token rates exclude any downstream model, speech or telephony costs unless the vendor states otherwise.
The enterprise product analytics platform, publicly traded (AMPL). Positioned as the alternative to Mixpanel for product teams that need advanced funnels, cohorts, and predictive analytics at scale. Distinctive for its 'North Star' methodology framework that many product-led-growth companies now use as their operating rhythm. Free tier limited; paid custom based on tracked events — Growth typically $50-200/mo entry, enterprise deployments run $48K-100K+/yr. Real cost bloat: tracked event volume compounds fast.
