frieren

Ultra fast alternative to prometheus, loki and tempo for open telemetry data in (development | testing | staging ) environments.

Test , experiment and verify your open telemetry instrumentation before pushing things to production.

Features

• Single binary,zero dependency: One frieren binary to rule them all.
• Supports PromQL , LogQL and TraceQL
• Painless: Just point your otel collector, or send the data directly via otlp.

exporters:
  otlp:
    endpoint: localhost:4317
    tls:
      insecure: true
service:
  pipelines:
    traces:
      exporters: [otlp]
    metrics:
      exporters: [otlp]
    logs:
      exporters: [otlp]

• Familiar API: query metrics with prometheus api, logs with loki api and traces with tempo api
• Crazy fast: We use compressed roaring bitmaps for extremely fast queries.
• Realtime: If the sample is accepted it is ready to be queried right away.
• Unlimited cardinality.
• Efficient: numeric data is stored in 2d compressed roaring bitmaps. Blobs are stored in content addressable store.
