Where each one falls short

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

Aider

  • Requires comfort working in a terminal rather than a graphical IDE
  • Has no hosted or managed version, so users must supply and pay for their own LLM API access separately
  • Depends heavily on the chosen underlying model's quality, so results vary by which LLM is configured
  • Lacks a built-in autonomous multi-step task runner comparable to agent-style products

Buildkite

  • Free plan caps at 5 users and 10 concurrent jobs, with 2,000 Linux vCPU minutes per month and 30 day build retention
  • Pro plan is $30 per active user per month, capped at 50 users, with only 10 of the up to 250 concurrent agents included before extra usage
  • Enterprise plan enforces a 30 user minimum even though pricing itself is custom
  • Hosted compute beyond included minutes is metered at $0.004 per vCPU minute on Linux and $0.02 per vCPU minute on Mac
