qryn: polyglot observability

:rocket: lighweight, multi-standard, polyglot observability stack for Logs, Metrics, Traces and Profiling

... it's pronounced /ˈkwɪr..ɪŋ/ or just querying

• Polyglot: All-in-one, Drop-in compatible with Loki, Prometheus, Tempo, Pyroscope
• Lightweight: Powered by Bun - the fast, all-in-one JavaScript runtime + ClickHouse OLAP Engine
• Familiar: Use stable & popular LogQL, PromQL, TempoQL languages to query and visualize data
• Voracious: Ingest using Opentelemetry, Loki, Prometheus, Tempo, Influx, Datadog, Elastic + more
• Versatile: Explore data with qryn's built-in Explorer and CLI or native Grafana datasource compatibility
• Secure: Retain total control of data, using ClickHouse, DuckDB or InfluxDB IOx with S3 object storage
• Indepentent: Opensource, Community powered, Anti lock-in alternative to Vendor controlled stacks

🚀 Get Started

Features

💡 qryn independently implements popular observability standards, protocols and query languages

:eye: Built-In Explorer

qryn ships with view - our zero dependency, lightweight data explorer for Logs, Metrics and Traces

➡️ Ingest

📚 OpenTelemetry

⚡ qryn is officially integrated with opentelemetry supports any log, trace or metric format Ingested data can be queried using any of the avialable qryn APIs (LogQL, PromQL, TraceQL)

💡 No modifications required to your opentelemetry instrumentation!

📚 Native

qryn supports native ingestion for Loki, Prometheus, Tempo/Zipkin and many other protocols With qryn users can push data using any combination of supported APIs and formats

💡 No opentelemetry or any other middlewayre/proxy required!

⬅️ Query

📚 Loki + LogQL

Any Loki compatible client or application can be used with qryn out of the box

⚡ qryn implements the Loki API for transparent compatibility with LogQL clients

The Grafana Loki datasource can be used to natively browse and query logs and display extracted timeseries

:tada: No plugins needed :eye: No Grafana? No problem! Use View

📈 Prometheus + PromQL

Any Prometheus compatible client or application can be used with qryn out of the box

⚡ qryn implements the Prometheus API for transparent PromQL compatibility using WASM 🏆

The Grafana Prometheus datasource can be used to natively to query metrics and display timeseries

:tada: No plugins needed :eye: No Grafana? No problem! Use View

🕛 Tempo + TraceQL

⚡ qryn implements the Tempo API for transparent compatibility with TraceQL clients.

Any Tempo/Opentelemetry compatible client or application can be used with qryn out of the box

The Tempo datasource can be used to natively query traces including TraceQL and supporting service graphs

:tada: No plugins needed :eye: No Grafana? No problem! Use View

🔥 Pyroscope + Phlare

⚡ qryn implements the Pyroscope/Phlare API for transparent compatibility with Pyroscope SDK clients.

Any Pyroscope SDK client or Pyroscope compatible agent can be used with qryn out of the box for continuous profiling

📚 Vendors Compatibility

qryn can ingest data using formats from Grafana, InfluxDB, DataDog, Elastic and other vendors.

With qryn and grafana everything just works right out of the box:

• Native datasource support without any plugin or extension
• Advanced Correlation between Logs, Metrics and Traces
• Service Graphs and Service Status Panels, and all the cool features
