[](https://github.com/metrico/qryn/actions/workflows/build_release.yml)     # [qryn: polyglot observability](https://qryn.dev) :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](https://qryn.metrico.in/#/installation) * Setup & Deploy **qryn** _OSS_ using the [documentation](https://qryn.metrico.in/#/installation) and get help in our [Matrix room](https://matrix.to/#/#qryn:matrix.org) :octocat: * Looking for a minimal setup for a quick test? Start with [qryn-minimal](https://github.com/metrico/qryn-minimal)

## 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](https://github.com/metrico/otel-collector) 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](https://qryn.metrico.in/#/support) for Loki, Prometheus, Tempo/Zipkin and _[many other protocols](https://qryn.metrico.in/#/support)_
With qryn users can _push data using any combination of supported APIs and formats_ > 💡 _No opentelemetry or any other middleware/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](https://github.com/lmangani/qryn/wiki/LogQL-Supported-Queries) for transparent compatibility with **[LogQL](https://grafana.com/docs/loki/latest/query/)** 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](https://prometheus.io/docs/prometheus/latest/querying/api/) for transparent **[PromQL](https://prometheus.io/docs/prometheus/latest/querying/basics/)** 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](https://github.com/lmangani/qryn/wiki/LogQL-Supported-Queries) for transparent compatibility with **[TraceQL](https://grafana.com/docs/tempo/latest/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](https://qryn.metrico.in/#/profiling/ingestion) 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](https://qryn.metrico.in/#/support) 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
