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.
- Dash0 (Per Usage) — Dash0 bills purely on usage — $0.20/M metrics + $0.60/M spans/logs/events (no monthly base). There is no fixed per-seat fee, so the monthly cost depends entirely on how much you consume.
- Vellum (Tiered) — Vellum bills on a fixed plan from $30/mo, so the listed price is what you pay regardless of volume.
Per-minute, per-credit and per-token rates exclude any downstream model, speech or telephony costs unless the vendor states otherwise.

What each is best for
Dash0 is worth it if… Dash0 is ideal for teams tired of predicting observability spend against per-host commits. Best if telemetry volume is bursty and you want granular per-signal cost visibility instead of tier-based billing.
Vellum is worth it if… individuals who want a persistent AI assistant that can execute multi-step tasks, keep files in a hosted workspace, and be reached via a custom email or subdomain. Mighty $30 suits casual daily use; Super $100 adds email/subdomain features for prosumers; Ultra $200 targets power users who lean on the assistant heavily.
Bottom line: Choose based on how you want to pay — Dash0 is per usage, Vellum is tiered.
