Cursor: Both provide AI-assisted code editing, but Cursor is a full IDE while Aider is a terminal tool

Aider
AI pair programming in your terminal
As of 1 September 2026, Aider is free to use. Open-source terminal tool that pairs developers with LLMs to edit code, using a codebase map and automatic git commits. Softwr lists it under AI. Aider is made by Aider AI LLC, launched in 2023, available on macOS, Linux, Windows, API.
Overview
What Aider does
Aider is an open-source command-line tool for AI-assisted software development. It connects to large language models such as Claude, GPT, DeepSeek, and local models to edit files across a codebase, automatically committing changes to git with descriptive messages. Aider builds a map of the repository to give the model context on larger projects, supports over 100 programming languages, and can incorporate images, web pages, and voice input into a coding session. It runs entirely in the terminal and integrates with existing editors via file watching.
What people use it for
- Editing an existing codebase from the terminal
- Pairing with an LLM on a new project
- Automating git-committed code changes
- Working across many programming languages
- Bringing your own LLM API key to a coding workflow

The honest half
Where it falls short
Concrete and checkable, so you can decide whether any of them matter to you. This is the half of a review a vendor will not write about Aider.
- Requires comfort working in a terminal rather than a graphical IDE
- Has no hosted or managed version, so users must supply and pay for their own LLM API access separately
- Depends heavily on the chosen underlying model's quality, so results vary by which LLM is configured
- Lacks a built-in autonomous multi-step task runner comparable to agent-style products

Questions people ask
Each answer names the page it came from, so you can check it rather than take our word for it.
Is Aider free to use?
Aider itself is free and open source, released under the Apache 2.0 license. Users must separately supply and pay for API access to the LLM they choose to use with it.
SourceWhich LLMs can I use with Aider?
Aider connects to OpenAI, Anthropic, Gemini, GROQ, DeepSeek, Ollama, Azure, Cohere, xAI, GitHub Copilot, Vertex AI, Amazon Bedrock, OpenRouter and most other LLM providers via API keys.
SourceCan I use Aider for free without paying for an LLM API?
Yes, Aider can be used at no cost through OpenRouter's free model access (subject to daily usage limits) or Google's Gemini 2.5 Pro Exp, which the docs note performs well without a paid API key.
SourceHow does Aider handle version control?
Aider automatically stages and commits each change it makes to a connected git repository, generating a descriptive commit message for every edit so changes stay reviewable and reversible.

Softwr does not host reviews and shows no star rating for Aider, because a rating we did not collect is not ours to publish. What is here is the pricing and platform detail from the vendor’s own pages, limitations we could state concretely, and alternatives a reviewer confirmed people weigh against it.
