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

* Setup & Deploy qryn _OSS_ using the documentation and get help in our Matrix room :octocat:
* Looking for a minimal setup for a quick test? Start with qryn-minimal

$3

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

➡️ Ingest

$3

⚡ 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!_

$3

qryn supports native ingestion for Loki, Prometheus, Tempo/Zipkin and _many other protocols_

> 💡 _No opentelemetry or any other middlewayre/proxy required!_

⬅️ Query

$3

> 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_

$3

> 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_

$3

⚡ 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_

$3

⚡ 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

$3

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
