Decision fit
Who Aider is best for
A terminal-first AI pair programmer that edits code inside a local Git repository.
Best for
- Developers who prefer a terminal-first coding workflow
- Users who want to choose their own hosted or local language model
- Teams that want AI edits represented as ordinary Git commits
- Developers who need a lightweight agent that works beside any editor
Tradeoffs to review
- Aider does not provide a first-party full IDE; editor integration is primarily terminal-side watch mode
- The software is free, but hosted model inference is billed by the selected provider
- Repository context and selected files are sent to the configured model provider unless a local model is used
- There is no managed cloud-agent dashboard, team administration layer, or built-in pull-request service
Available surfaces
Terminal CLI · Experimental local browser UI · Watch-files workflow beside any editor · Python and command-line scripting
Execution environments
Local Git repository · Docker container · GitHub Codespaces · Local Ollama or OpenAI-compatible model endpoint

What Aider is
Aider is an open-source AI pair programmer that runs in a terminal and directly edits files in a local repository. It is designed to stay small, model-independent, and compatible with an existing editor and development toolchain.
- 01
Installs as a Python command-line application on macOS, Linux, and Windows
- 02
Works on existing repositories and can create new source files
- 03
Supports many commercial APIs, OpenAI-compatible endpoints, and local models
- 04
The Apache-2.0 project is available from its official GitHub repository

02 · Product analysis
Coding workflow
Users add files to a conversation, request a change, inspect the resulting diff, and continue iterating in the terminal. Aider can automatically lint edited files and run configured tests after changes.
- 01
Code mode changes files while ask mode discusses the repository without editing
- 02
Architect mode uses one model to design a change and another to translate it into edits
- 03
Built-in commands expose diffs, file context, linting, tests, and shell output
- 04
Automatic lint and test loops can ask the model to repair failures
Primary evidence: Aider chat modes, checked 2026-07-12.
03 · Product analysis
Agent behavior and orchestration
Aider focuses on one interactive coding session rather than parallel cloud agents. Architect mode provides a limited two-model pipeline, and the CLI can be scripted for non-interactive automation.
- 01
Architect mode separates solution reasoning from edit generation
- 02
Commands can be loaded or piped for repeatable workflows
- 03
The agent can run local lint, test, and shell commands
- 04
Parallel worktrees and a hosted multi-agent task board are not included
Primary evidence: Aider chat modes, checked 2026-07-12.
04 · Product analysis
Context and model extensibility
Aider builds a graph-ranked repository map containing important symbols and signatures, then combines it with explicitly added files. Its model layer supports numerous hosted providers, OpenAI-compatible APIs, and Ollama.
- 01
The repository map selects relevant symbols to fit a configurable token budget
- 02
Users explicitly add and remove editable files from chat context
- 03
Images and web pages can be added to supported model conversations
- 04
Local models can run through Ollama or a compatible local API
Primary evidence: Aider repository map, checked 2026-07-12.
05 · Product analysis
Git, testing, and delivery
Aider's delivery workflow is local and Git-native. It commits edits, exposes diffs, supports one-command undo, and can run project tests, while the user retains responsibility for branches, pull requests, CI, and deployment.
- 01
Each AI edit can be automatically committed with a generated message
- 02
The undo command reverts the most recent AI change
- 03
Dirty user changes are separated from Aider edits before modification
- 04
Pull-request creation and managed deployment are outside the core product
Primary evidence: Aider Git integration, checked 2026-07-12.
06 · Product analysis
Pricing and usage
The Aider client is open-source and has no subscription tier. Total cost is determined by the chosen model provider, token volume, caching, or the hardware used for a local model.
- 01
There is no paid Aider client plan
- 02
Commercial API keys are billed independently of consumer chat subscriptions
- 03
Some providers expose free models or limited free tiers
- 04
Local Ollama inference avoids per-request API charges but requires suitable hardware
Aider is free, open-source software; model access is separate
See official pricing
See official pricing
Aider does not charge a client subscription. Users pay their selected hosted model provider by token or use a free or locally hosted model on their own hardware.

Security and privacy
Aider runs locally, but relevant files, prompts, and repository-map context are processed by the selected model provider. Its optional analytics exclude source code, chats, keys, and personal information and require opt-in.
- 01
Anonymous product analytics are opt-in and can be permanently disabled
- 02
Analytics do not collect code, chat messages, API keys, or personal information
- 03
Using a local model can keep model context on the user's machine
- 04
API-provider privacy and retention terms apply when a hosted model is configured

FAQ
Questions about Aider
Is Aider free?
Yes. Aider is open-source software with no client subscription. Hosted model API use is billed separately by the provider, while local models use your own hardware.
Does Aider work inside an IDE?
Aider is terminal-first. Its watch-files mode can coordinate with any editor, and it can run in an IDE terminal, but third-party plugins are not the primary first-party interface.
Can Aider use local models?
Yes. Aider supports Ollama and local OpenAI-compatible endpoints, although official documentation warns that weaker models may struggle to produce reliable file edits.
How does Aider protect changes?
Aider can commit each edit to Git, show the diff, keep pre-existing changes separate, and undo its most recent change. Users may disable automatic commits if preferred.
