Migrate from Honeycomb to Logfire

Honeycomb is OpenTelemetry-native — you already send OpenTelemetry Protocol (OTLP) data, authenticated with the x-honeycomb-team header, to api.honeycomb.io (or api.eu1.honeycomb.io for EU). Migrating to Logfire swaps the endpoint and that header for Logfire’s Authorization header. Nothing else changes; see Migrate to Logfire for the general shape.

You’ll need a Logfire write token and your region endpoint (https://logfire-us.pydantic.dev or -eu).

If your apps export OTLP

Point the SDK’s OTLP variables at Logfire and replace the Honeycomb team header with Authorization:

Terminal
# before (Honeycomb):
#   OTEL_EXPORTER_OTLP_ENDPOINT=https://api.honeycomb.io
#   OTEL_EXPORTER_OTLP_HEADERS='x-honeycomb-team=your-honeycomb-key'
export OTEL_EXPORTER_OTLP_ENDPOINT=https://logfire-us.pydantic.dev
export OTEL_EXPORTER_OTLP_PROTOCOL=http/protobuf
export OTEL_EXPORTER_OTLP_HEADERS='Authorization=your-write-token'
export OTEL_SERVICE_NAME=your-service-name

If you run the OpenTelemetry Collector

Change the Honeycomb exporter’s endpoint and header to Logfire’s:

exporters:
  otlphttp/logfire:
    endpoint: "https://logfire-us.pydantic.dev"  # or https://logfire-eu.pydantic.dev
    headers:
      # was: "x-honeycomb-team": "your-honeycomb-key"
      Authorization: "Bearer ${env:LOGFIRE_TOKEN}"

service:
  pipelines:
    traces:
      exporters: [otlphttp/logfire]
    metrics:
      exporters: [otlphttp/logfire]
    logs:
      exporters: [otlphttp/logfire]

To cut over gradually, keep both exporters in the pipeline and compare the same traffic in each before removing Honeycomb.
