Sematext Free Tier 2026

stable

Subtypes in Monitoring: log_management — ingests, stores and queries log lines; the line is the stored unit and retention is a priced dimension; host_metrics — an agent you install on a machine reports CPU, memory, disk and process state for that machine; synthetic_check — runs a check you author — a scripted browser session, a multi-step API call, or an assertion on a response body — on a schedule from outside your infrastructure, and reports whether the behaviour it asserts still holds. We read that on 2026-09-01 from https://sematext.com/pricing, where it says: “Start free trial Synthetics Monitor performance and availability of your site and APIs.” How we use this.

Retracted — this record was our error (2026-09-07). Retracted 2026-09-07: this record compared two different products on sematext.com/pricing. The stored terms describe the Logs Basic plan, and the page's Logs Basic card still reads "Retention 7 days" and "Daily Volume 500 MB/day" — both stored figures unchanged. The "Retention 1 day" and per-host price this record reports are the Infra Monitoring Basic card, a different product on the same page. The page's FAQ reads "Each Monitoring App is independent and each App can have a different plan, including the free plan." Source ↗

How Sematext compares against every one of the 27 we list, not against a selection of them. A surface with room for every member of a tied set may rotate their order. A surface with room for only some of them names none of them, because which ones it named would be the claim, and a claim seeded on the date is not the one we serve tomorrow. How we decide this.
