Revolutionary Observability Pricing
It bites to be charged by the byte. Dartastic Hosted is a flat per-box price — capacity expands when metrics reach thresholds. Plug in your numbers to compare.
Your app
Applies to traces & RUM sessions on every backend; errors are always kept. High-volume teams typically keep 5–25%.
≈ 30,200,000 telemetry events/mo (1,500,000 sampled sessions × 20 spans + 200,000 errors). Competitors shown at list price (no discounts assumed).
Dartastic Hosted
$199/mo
1 × Hosted Dev box × $199 = $199
retention storage included
7-day traces · 30-day metrics — flat & predictable. Autoscales at ~90% compute (terms).
A dedicated single-tenant stack — shared usage tools are cheaper at small scale, but Dartastic stays flat as you grow (and never makes you sample to save money).
Just getting started? Dartastic Cloud Observatory handles this volume on shared infrastructure for about $39/mo (≈ 9.1 GB ingest, within the included 10 GB). One unified byte meter, card-required 7-day free trial.

Assumptions (editable) — estimates as of June 2026
Dartastic is priced as box (compute) + retention storage: the box is bound by compute (ingest is a non-issue), and the data your retention SLA implies (events × bytes/event × retention) lives on included NVMe plus a flat $/GB-month add-on beyond it — so a longer-retention or higher-volume app pays for the storage it actually keeps, predictably. Box and bytes/event figures are estimates pending a bytes-per-span measurement; real numbers depend on signal mix, cardinality, and compression. Competitors are shown at list price with no negotiated discounts (the only number a customer can predict); sampling reduces traces/sessions on every backend, errors are never sampled. The Sentry figure counts errors plus tracing spans (the real cost driver on Sentry's 2026 span-based meter) but not its separately-metered logs and metrics GB, replays, or per-seat fees, so it still understates. Dartastic Cloud Observatory is estimated as a $39 base (10 GB unified-byte ingest included) plus $10 per 25 GB prepaid pack, sized from the same events × bytes/event volume. Verify with each vendor.
