# Loguro > The Log Operating System. Query 50M logs in under 500ms with human-readable syntax. Replay incidents chronologically, detect recurring patterns forever, and act — create Jira tickets, notify Slack — all from one command bar. Loguro is a high-performance log management system built around a single principle: zero context switch. Everything you normally do across 4 tabs (Jira, Slack, Datadog, calendar) happens directly from Loguro's command bar. ## Key differentiators - **Incident Replay** — select a time range on the chart, press Replay. Logs stream in exact chronological order at 1x/2x/4x/10x speed with original time distances preserved. See the warning 2 minutes before the crash, the cascade across services, the recovery. Nobody else does this. - **Forever Memory** — when you create a task from a log, Loguro normalizes the message pattern and recognizes any similar log automatically in the future. The original log is stored permanently in Parquet — never expires, regardless of plan. - **Human-readable filter syntax** — `level:error message:"payment" from:yesterday to:today` — not SQL, not Lucene, not regex. - **Zero context switch** — filter logs, create a Jira ticket, notify Slack, configure an alert, export data — all from the same command bar with `--task:jira`, `--send:slack`, `--alerts`, `--downloads`. - **`--diff` anomaly detection** — compare log patterns between two time windows. Surfaces new errors, spikes, and resolved patterns instantly. No ML setup required. ## Performance - 45,000 req/s ingestion (single node) - 400,000+ logs/s in batch mode - Sub-500ms query on 50M+ logs (DuckDB + Parquet columnar storage) - Logs visible in UI within few seconds via WebSocket + Redis pub/sub ## Tech stack - Query engine: DuckDB (in-process columnar analytics) - Storage: Apache Parquet (tiered L0/L1/L2) - Database: Turso (LibSQL) with Drizzle ORM - Frontend: SvelteKit 5 - API: Hono ## Integrations - Issue trackers: Jira, Linear, GitHub Issues - Messaging: Slack, Discord, Telegram ## Docs - Docs index: https://logu.ro/docs - Getting started: https://logu.ro/docs/getting-started - Filter syntax reference: https://logu.ro/docs/filter-syntax - Command reference: https://logu.ro/docs/commands - API reference: https://logu.ro/docs/api ## Blog - Blog index: https://logu.ro/blog ## Links - Homepage: https://logu.ro - Pricing: https://logu.ro/pricing - Get started: https://logu.ro/get-started - Sitemap: https://logu.ro/sitemap.xml
