# Gigapipe > Polyglot observability warehouse on ClickHouse. Ingest logs, metrics, traces and > profiles via OpenTelemetry, Loki, Prometheus, Tempo, Pyroscope, InfluxDB, Elastic or > Datadog, then query them with LogQL, PromQL and TraceQL from Grafana with no plugins. Gigapipe (formerly qryn) is an open source, single-binary observability backend. It stores all four telemetry signals in ClickHouse and reimplements the Loki, Prometheus, Tempo and Pyroscope HTTP APIs, so existing agents and Grafana datasources work against it unchanged. Licensed AGPL-3.0. - **Ingest formats:** OpenTelemetry (OTLP over HTTP and gRPC), Loki, Prometheus, Tempo, Zipkin, Pyroscope, InfluxDB, Elastic, Datadog - **Query languages:** LogQL (logs), PromQL (metrics), TraceQL (traces), Pyroscope API (profiles) - **Storage:** ClickHouse, with S3-compatible object storage - **Pricing model:** flat, based on infrastructure size — not per-GB ingested, per-host or per-seat ## Docs - [SaaS documentation](https://gigapipe.com/docs): hosted setup, tokens and Grafana access - [Open source documentation](https://gigapipe.com/docs/oss): self-hosted install, configuration and operation - [API documentation](https://gigapipe.com/docs/api): ingestion and query endpoints per protocol - [Configuration](https://gigapipe.com/docs/config): environment variables and Docker setup - [Compatibility](https://gigapipe.com/compatibility): supported agents, clients and vendor formats - [OpenTelemetry](https://gigapipe.com/opentelemetry): OTLP ingest paths per signal, both transports and Collector configuration - [Live demo](https://gigapipe.com/docs/demo): interactive sandbox ## Product - [Homepage](https://gigapipe.com/): overview and positioning - [Pricing](https://gigapipe.com/pricing): flat-rate plans - [Source code](https://github.com/metrico/gigapipe): AGPL-3.0, written in Go - [Marketplace](https://gigapipe.com/new): integrations and extensions - [GigaNews](https://gigapipe.com/news): releases and changelog ## Comparisons - [vs Datadog](https://gigapipe.com/datadog-alternative): protocol compatibility, agent reuse and pricing shape - [vs Grafana Cloud](https://gigapipe.com/grafana-cloud-alternative): keeping Grafana, replacing the storage and billing underneath ## Writing - [Engineering blog](https://blog.gigapipe.com/): observability cost, OpenTelemetry and ClickHouse deep dives
