Why teams compare

Why developers compare Helicone with unlimitedcodex

  • You need ChatGPT 5.5 Ultra and Codex API access with unlimited token consumption and 4 concurrent connections, not a paid observability proxy
  • Helicone logs requests but you still pay OpenAI per token for the actual inference
  • Heavy Codex agent usage makes per-token bills unpredictable on top of Helicone fees
  • Flat API access with unlimited token consumption and 4 concurrent connections at $19/week is simpler than proxy subscription plus inference
