What we evaluated
Evaluation criteria: IDE completion loops, CLI multi-file edits, Git workflow friction. Conclusions are based on primary documentation, product evidence, and workflow fit — not hands-on benchmark runs unless noted. 5 primary sources checked.
GitHub Copilot is the default for IDE-native coding help. Aider is the alternate for CLI pair programming with git-aware multi-file edits and BYO models.
Pick Copilot for always-on editor assist. Pick Aider when the terminal is the workstation.
Aider’s price, checked 12 October 2026. Aider’s FAQ says the project is open source under the Apache 2.0 license. Connecting to LLMs is how you run it: your model provider’s API key, a local model such as Ollama, or a provider that offers a free allowance. aider.chat does not list an Aider subscription. The software is free. You pay the model provider’s API usage, unless the model is local.
Terminal coding agents
Aider is a terminal pair programmer with your own models. Two other terminal agents ride a subscription you may already have.
Claude Code is Anthropic’s coding agent for the terminal. On Claude pricing, checked 12 October 2026, Claude Code is included on every paid plan and is not on Free. Pro is $20/month, or $17/month billed annually ($200 up front). Max plan help lists Max 5x at $100/month and Max 20x at $200/month, monthly only, and includes Claude Code on that subscription. It shares the plan’s usage limits. A Claude Console account bills API tokens instead. The Claude Code page also lists Team, Enterprise, and a Console account as ways in. For the editor-versus-terminal choice, see Cursor vs Claude Code. For Claude Code versus Codex, see Claude Code vs Codex.
GitHub Copilot CLI is the terminal client on a Copilot plan. GitHub’s plans page, checked 12 October 2026, says all plans include Copilot CLI and the Copilot app. Pro is $10/month with 1,500 GitHub AI credits (1,000 base plus 500 flex). Pro+ is $39/month with 7,000 credits. Max is $100/month with 20,000 credits. Business is $19 per seat per month with 1,900 credits. Enterprise is $39 per seat per month with 3,900 credits. Free includes 2,000 completions a month and a limited credit allowance. CLI usage draws on those credits.
What we evaluated: IDE loops, CLI edits, and git friction. Copilot won for most teams. Aider won for CLI-first agent work.
