Methodology & data sources
Transparency is the core of our E-E-A-T: this page documents where our data comes from, how often it is refreshed, and the formulas behind every calculation.

How the pricing snapshot works
Every price on this site is a dated snapshot (June 2026) of a figure published on the vendor's own pricing page, linked on each vendor page. Observability pricing is modular and volatile - it varies by tier, region, retention, volume and negotiated discounts - so we never present a price as universal or current. Where a vendor does not publish a flat number (usage-based, credit-based or contact-sales pricing), we mark it as such and never invent a figure. We do not store your inputs.
How derived figures are calculated
- Rankings sort vendors by a single published rate (e.g. per-GB log ingest, headline entry cost). Vendors without a comparable flat rate are listed separately, not guessed into the ranking.
- The cost calculator computes
(hosts × per-host rate) + (billable log GB × per-GB rate)using only published rates, applying known free allowances (New Relic 100 GB, Grafana and Better Stack 50 GB logs). It excludes APM/RUM add-ons, log indexing, data transfer, support and discounts, and lists per-event / per-vCPU / custom vendors as not directly comparable. - Free-tier classification distinguishes a genuine permanent free tier from a time-limited trial.
Limitations
Figures are a dated snapshot for general information and may lag the vendor's current pricing or contain errors. They are not quotes. Always verify against the vendor's pricing page before relying on them. See our disclaimer.
