What is Aider?
Aider is an AI pair programming tool that runs in your terminal. It understands your git repository, can edit multiple files at once, and automatically creates git commits with descriptive messages. With over 25,000 GitHub stars, it is one of the most popular AI coding tools for developers who prefer the command line. Aider consistently tops coding benchmarks and supports a wide range of models.
Aider supports custom OpenAI-compatible endpoints through environment variables. Set OPENAI_API_BASE to EUrouter and your API key, and every LLM call Aider makes routes through EU servers. Your code context, diffs, and conversation history stay within European jurisdiction.
Quick to integrate
A few lines of code is all it takes. Swap your base URL and you are routed through EUrouter.

1aiderWhy use Aider with EUrouter
Git-aware coding through Europe
Aider understands your git repository: it reads files, makes edits across multiple files, and creates commits with meaningful messages. All of that context, your code, diffs, and repo structure, routes through EUrouter's EU servers.
- Multi-file edits and git commits route through EU infrastructure
- Repository context and file diffs stay within European jurisdiction
- Automatic git commit messages generated through EU-hosted models
- Works with any git repository regardless of size
Top-ranked with any model
Aider consistently tops AI coding benchmarks. Through EUrouter, you can pair its editing capabilities with any supported model: GPT-4o, Claude, Mistral, and more. One API key, one config change.
- Access all EUrouter models from the command line
- Switch models with the --model flag or config file
- Benchmark-leading code editing with EU data residency
- One API key covers all model usage
Flexible configuration
Aider supports environment variables, CLI flags, and YAML config files. Set the EUrouter endpoint once in your preferred way and every session uses it. Per-project configs let you use different settings for different repositories.
- Environment variables, CLI flags, or .aider.conf.yml for configuration
- Per-project config files for different settings per repository
- Works alongside existing Aider settings without conflicts
- Easy to share team-wide config via checked-in config files
