Aider vs Continue
A detailed comparison to help you choose the right tool for your needs.
Last updated: 2026-02-06
Aider
Free (open source), you pay for API usage
Strengths
- + Git-aware — every change is a well-described commit you can review or revert
- + Works with Claude, GPT-4, Gemini, and local models
- + Top scores on SWE-bench coding benchmarks
Weaknesses
- − Terminal-only — no GUI, no visual diff preview
- − API costs are yours to manage and can add up with large context
- − Learning curve to get the most out of it (knowing which files to add, how to prompt)
Continue
Free (open source)
Strengths
- + Completely free — no subscription, no API costs if you use local models
- + Works with any LLM: OpenAI, Anthropic, Ollama, LM Studio, and more
- + Deep IDE integration with autocomplete, chat, and inline editing
Weaknesses
- − Requires setup — picking a model, getting API keys, configuring the tool
- − Less polished than Cursor or Copilot; occasional rough edges
- − Quality is only as good as the model you connect

About each tool
Aider
Open-source terminal AI that edits your code and makes clean git commits automatically
Aider is a terminal tool that pair-programs with you. You tell it what to change, it edits the files, and — here is the part that wins people over — it creates a clean git commit with a descriptive message. Every change is tracked, reviewable, and revertable. No other AI coding tool handles version control this naturally.
Built by Paul Gauthier, it consistently ranks at the top of SWE-bench coding benchmarks. The tradeoff is that it is terminal-only and requires you to bring your own API key. If you are already comfortable with git and the command line, aider fits into your workflow like a glove. If you want a visual editor experience, look at Cursor or Cline instead.

Open-source AI assistant for VS Code and JetBrains — plug in any LLM, including free local models
Continue is the “bring your own brain” approach to AI coding. It is a free, open-source extension for VS Code and JetBrains that connects to any LLM you want — cloud APIs like Claude and GPT-4, or local models through Ollama. You get autocomplete, chat, and inline editing without paying for a subscription.
The appeal is total freedom. Do not want to send code to the cloud? Run a local model. Want to switch between Claude for complex tasks and a fast local model for autocomplete? You can. The cost is setup time and some polish — it takes more effort to get running than Cursor, and the experience is not quite as seamless. But for developers who want control over their tools and their data, Continue is the best free option.
