Aider — terminal-native, open-source (Apache 2.0) AI pair programming tool. Git-aware (auto-commit), BYO API key (Claude/GPT-5/Gemini/DeepSeek/Ollama local), 100+ languages, voice input. Zero-to-advanced Turkish guide: install, /add /drop /diff commands, model selection, repo map (tree-sitter), git workflow, local Ollama KVKK setup, comparison to Claude Code/Cursor, 10 use cases + typical costs.
One-line answer: Aider is terminal-native, git-aware, open-source AI pair programming — flexible + free alternative to Claude Code/Cursor, gold solution for KVKK with local Ollama.
- Aider — terminal CLI open-source (Apache 2.0) AI pair programming tool. Released May 2023 by Paul Gauthier. 30K+ GitHub stars, the most mature terminal AI coding tool.
- Core feature: GIT-AWARE — every AI change auto-committed (conventional commits). Easy undo (git reset).
- BYO API key: Anthropic Claude, OpenAI GPT-5, Google Gemini, DeepSeek, Groq, Together AI, Ollama (local), LM Studio (local), 100+ providers via router.
- 100+ programming languages with tree-sitter repo map: Python, JavaScript, TypeScript, Go, Rust, Java, C++, Ruby, Swift, Kotlin, even SQL/HTML/CSS.
- Simple command system: /add, /drop, /code, /architect, /ask, /diff, /undo, /commit, /lint, /test.
- Positioned as the open-source alternative to Claude Code — not tied to Anthropic, works with any LLM. Limited hooks and MCP but simpler + auditable in Python.
- KVKK GOLD: Aider + Ollama + DeepSeek/Qwen local model = 100% KVKK compliance + zero API cost.
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.
