ClickHouse-powered log search, real-time tail, smart alerts, and automatic anomaly detection. Free to start. $19/mo when you grow.
ClickHouse-powered full-text search across billions of log lines. Filter by level, service, host, or any custom attribute. Results appear before you finish typing — no index warming, no query builder to learn.
Stream logs from all services directly in your browser at full speed. Filter by service or keyword, watch the logs/sec counter tick, copy raw JSON with one click. No page reloads, no polling.
Keyword match, error rate thresholds, volume spikes, silence detection. Routes to Slack, Telegram, email, Discord, or a custom webhook. Configurable cooldowns — one page per event, not six.
Errors are fingerprinted, normalized, and collected into Issues automatically. Track regressions, request AI summaries, resolve or mute noise independently from the raw log stream.
All features ship in every plan — limits are on data volume, retention, and team size only.
