Pricing
FreeAider itself is completely free and open source under the Apache 2.0 license, with no subscription, tiers, or usage limits imposed by the project. Costs come entirely from the LLM provider a developer chooses to connect: for example, Anthropic, OpenAI, or DeepSeek API usage is billed directly by that provider at its own per-token rates, or developers can run local models through Ollama at no cost at all. Because there is no Aider-specific markup or platform fee, effective cost is determined by model choice and usage volume rather than by Aider itself.
PaidClaude Code is included in every paid Claude plan rather than sold separately. Pro is $17/month billed annually ($200 upfront) or $20/month billed monthly. Max starts at $100/month for 5x the usage of Pro, or $200/month for 20x the usage. Team offers Standard seats at $20/seat/month billed annually ($25/month billed monthly) and Premium seats (5x more usage) at $100/seat/month billed annually ($125/month billed monthly), with the ability to mix and match seat types. Enterprise is $20/seat/month plus usage billed at standard API rates, billed annually, and adds SCIM, audit logs, role-based access, custom data retention, and a HIPAA-ready offering. All plans share a single usage pool between Claude Code and Claude.ai chat activity, resetting on a rolling five-hour session window with weekly caps on paid plans; usage credits can be enabled on paid plans to continue working at standard API rates after hitting a limit. Claude Code is not available on the Free plan, but can also be accessed pay-as-you-go through a Claude Console (API) account.

Summary
Free, open-source AI pair programming that lives in your terminal
Anthropic's agentic coding tool that lives in your terminal
Aider Pros & Cons
Pros
- Completely free and open source, with no platform markup on top of LLM provider API costs
- Deep git-native workflow makes every AI change individually reviewable, diffable, and reversible
- Model-agnostic support for 100+ LLM providers, including local models, avoids vendor lock-in
- Efficient repo mapping keeps large codebases manageable without dumping entire files into context
- Transparent, actively maintained public leaderboard helps developers pick the best-performing model for real coding tasks
Cons
- Terminal-only interface has a learning curve for developers used to GUI-based tools like Cursor or Copilot
- No bundled AI access; users must bring their own API keys and manage separate billing with LLM providers
- Deliberately not a fully autonomous agent, staying one step behind tools like Devin that run unsupervised for longer stretches
- No official enterprise support tier or SLA, since the project is community-maintained open source
Claude Code Pros & Cons
Pros
- Deep codebase awareness that spans the full project rather than just the open file
- Fully scriptable and composable, fitting naturally into CI pipelines and existing terminal workflows
- MCP support connects it to external tools like Google Drive, Figma, Slack, and Jira
- Included in every paid Claude plan rather than requiring a separate subscription
- Available across terminal, IDE, desktop app, and browser for flexible workflows
Cons
- Not included in the Free plan; requires a paid Pro, Max, Team, or Enterprise subscription, or a pay-as-you-go API account
- Usage is pooled with regular Claude chat activity on subscription plans, so heavy terminal sessions can eat into the same limits used for everyday chatting
- Terminal-first design means it lacks the point-and-click familiarity of a full GUI IDE for developers who prefer that workflow
- Heavy agentic or automated workloads can run up token costs quickly if not managed with context management commands
- Enterprise-grade controls like SSO, SCIM, and audit logs require Team or Enterprise plans rather than being available on Pro
