## Why switch

Developers want a mature open-source pair programmer with git-native commits and pay-as-you-go model costs. Shifts from a fixed $20/mo seat to pay-as-you-go API tokens.

## Cost delta

| | Claude Code | Aider |
|---|---|---|
| Entry paid plan | Claude Pro ($20/mo) | — |
| Per-seat monthly delta | −$20 | |
| 10-dev team annual delta | −$2,400 | |

Shifts from a fixed $20/mo seat to pay-as-you-go API tokens. Model it: https://ai.dosa.dev/tools/cost-calculator?team=10&seats=none&preset=daily

## Config migration

- Claude Code rules: `CLAUDE.md`
- Aider rules: `CONVENTIONS.md`
- Convert with the Rules Converter: https://ai.dosa.dev/tools/rules-converter?from=claude-md&to=agents-md

## 4-step checklist

1. **Audit & export your Claude Code rules** — Claude Code reads repo-level rules from CLAUDE.md. Convert them to CONVENTIONS.md with the Rules Converter, then review the output before committing. (https://ai.dosa.dev/tools/rules-converter?from=claude-md&to=agents-md)
2. **Install & configure Aider** — Install Aider with `python -m pip install aider-install && aider-install`. Aider loads conventions with `aider --read CONVENTIONS.md` (or `read:` in .aider.conf.yml). Pricing: Open Source. (https://aider.chat?utm_source=ai.dosa.dev&utm_medium=referral)
3. **Adapt your daily workflow (CLI Agents → CLI Agents)** — You trade a managed subscription for a bring-your-own-key setup — configure provider credentials and watch token spend instead of seat count. Aider is best for developers comfortable with command-line workflows who want full control over model selection, git-centric history, and cost-efficient coding without subscription markups.
4. **Run a one-week parallel pilot, then reallocate seats** — Shifts from a fixed $20/mo seat to pay-as-you-go API tokens. Keep Claude Code active for one sprint while Aider handles new tasks; cancel seats only after velocity holds. (https://ai.dosa.dev/tools/cost-calculator?team=10&seats=none&preset=daily)

## What you gain

- Aider is best for developers comfortable with command-line workflows who want full control over model selection, git-centric history, and cost-efficient coding without subscription markups.
- Automatic git integration and commit generation.
- Repository mapping for large-scale codebase context.
- Architect mode for splitting complex reasoning from code implementation.

## What you give up

- Claude Code is positioned for solo founders, indie hackers, and developers working in real-world codebases who need help with complex, multi-file engineering tasks like refactoring and bug fixing. — confirm Aider covers that before cancelling seats.
- Aider is not ideal for users who prefer a graphical IDE interface, built-in visual diff tools, or a managed commercial product with guaranteed support and predictable flat-rate pricing.

Running both: Running both is mostly redundant — pilot Aider on one repo for a sprint, then pick one.

## FAQ

### How do I convert my Claude Code rules to Aider?

Claude Code reads CLAUDE.md and Aider reads CONVENTIONS.md. Run them through the Rules Converter (https://ai.dosa.dev/tools/rules-converter?from=claude-md&to=agents-md) and review the output before committing.

### Is Aider cheaper than Claude Code?

Claude Code starts at Claude Pro ($20/mo); Aider has no listed per-seat plan. Shifts from a fixed $20/mo seat to pay-as-you-go API tokens.

### What do I lose when switching from Claude Code to Aider?

Claude Code is positioned for solo founders, indie hackers, and developers working in real-world codebases who need help with complex, multi-file engineering tasks like refactoring and bug fixing. — confirm Aider covers that before cancelling seats. Aider is not ideal for users who prefer a graphical IDE interface, built-in visual diff tools, or a managed commercial product with guaranteed support and predictable flat-rate pricing.

### Can I use Claude Code and Aider together?

Running both is mostly redundant — pilot Aider on one repo for a sprint, then pick one.
