Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Retrace

  • End of Life scheduled for March 31, 2027; the product is being discontinued
  • Costs escalate quickly with per-server billing model, expensive at scale
  • User interface and dashboard criticisms; UI is outdated and difficult to use
  • Logging latency; logs can take time to appear and are not instant
  • Less mature support for Node.js, Python, and newer ecosystems
  • Reporting issues where process restarts provide only timeline without root cause data
  • Reliability concerns; monitoring has stopped collecting traces with no warning

Fluentd

  • Fluentd needs more than 60 MB of memory at runtime, against roughly 450 KB for Fluent Bit
  • Fluentd is built as a Ruby gem and depends on other gems, so a Ruby runtime is required
  • Its capability comes from over 1,000 external plugins rather than built in functionality, so each added input or output is a separate dependency
  • The Fluent Bit documentation states that cloud providers have switched from Fluentd to Fluent Bit for performance and compatibility and calls Fluent Bit the next generation solution
