Where each one falls short

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

Ably

  • Standard and Pro plans layer usage-based charges for messages, connection minutes, and data transfer on top of the base subscription, adding cost complexity.
  • The jump from Standard ($29/month) to Pro ($399/month) is steep for teams needing more than 10k connections but not full Pro capacity.
  • 24/7 mission-critical support and 99.999% uptime SLAs are reserved for the custom-priced Enterprise tier.

GitHub Copilot

  • Agent mode lacks deep tool orchestration and iterative execution compared to specialized agentic tools
  • Suggestions for niche or specialized programming languages are less accurate due to limited training data
  • Less effective with non-English prompts or grammatically incorrect developer instructions
  • Free tier severely limited to 2,000 completions and 50 chat requests per month
