What is Aider? 2026 Comprehensive Turkish Guide for AI Pair Programming in the Terminal

## 1. What is Aider? Open-source (Apache 2.0) terminal-native AI pair programming tool released by Paul Gauthier in May 2023. Git-aware (every change auto-committed), 100+ programming languages, BYO API key, tree-sitter repo map. 30K+ GitHub stars in 2026. ## 2. Installation pipx install aider-install (recommended). Requires Python 3.10+, Git, and an API key (Anthropic / OpenAI / Google / DeepSeek / etc.) or Ollama for local. ## 3. Commands - /add: add file to context - /drop: remove file - /code (default): coding mode - /architect: plan + diff mode - /ask: Q&A without changes - /diff: last commit diff - /undo: revert last AI commit - /voice: microphone input - /web: add web page to context ## 4. Git-Aware Workflow Every AI change is auto-committed in conventional commits format. /undo reverts via git reset. Easy to experiment safely. ## 5. Repo Map Tree-sitter parses your repo's class/function signatures into a "map" the AI uses to find relevant files automatically — reduces need to manually /add. ## 6. Local Ollama Setup (KVKK) ollama pull qwen2.5-coder:32b then aider --model ollama/qwen2.5-coder:32b — fully local, zero API cost, 100% KVKK compliant. ## 7. Aider vs Claude Code vs Cursor - **Aider:** open-source, git-aware leader, local Ollama support, BYO model - **Claude Code:** Anthropic official, MCP leader, sub-agents, hooks - **Cursor:** IDE experience, inline tab + Composer ## 8. Cost Heavy: ~$300-500/mo with Claude Sonnet. Medium: $80-150. Light: $20-40. Local Ollama: $0 (hardware-only). ## 9. Conclusion Aider is the open-source terminal-native AI pair programming champion. Git-aware auto-commit, architect mode, voice input are unique strengths. Local Ollama support makes it the 100% KVKK-compliant zero-cost option for Turkish enterprises.
