When to choose Aider
Aider is the leading open-source terminal coding agent: it maps your git repo, edits multiple files, commits with sensible messages, and works with any LLM including local models.
Aider gives you 80% of Claude Code's agentic workflow with full control of model and cost. It's the tinkerer's choice — worth it if you enjoy configuring your tools.Read our full Aider review →
When to choose GitHub Copilot
GitHub Copilot autocompletes code, chats about your repo, and now runs an autonomous coding agent that opens pull requests — integrated into VS Code, JetBrains and github.com itself.
Copilot is the sensible default for most teams: cheap, everywhere, and multi-model now. Individual power users increasingly prefer Cursor or Claude Code for agentic work — but Copilot's floor is high.Read our full GitHub Copilot review →
