Aider (aider)

### About this repository This is not our API. This repository is an independent, third-party profile of a company's publicly available API surface, maintained by API Evangelist. API Evangelist does not operate, host, resell, or support this company's APIs, and is not affiliated with or endorsed by the company unless stated on the profile. Where the information came from. Everything here is assembled from material a member of the public can reach with a browser and no credentials — the company's own website, developer portal and documentation, the specifications it publishes for public use (OpenAPI, AsyncAPI, JSON Schema, apis.json, llms.txt and similar), its public repositories, and its public status, pricing and changelog pages. Nothing here is obtained by breaching a system, defeating an access control, or using credentials of any kind. The rating is an independent assessment. The Kin Score and Agent Readiness rating are independently calculated scores of a company's public API artifacts, produced by API Evangelist against a published rubric. They are not certifications, endorsements, security assessments, or audits, and they score published artifacts — not the quality, safety, or security of the software. Corrections, re-scores, and removal are free. No partnership, contract, or purchase is required, and you do not need to justify the request. - Something wrong? Open an issue on this repository, or email info@apievangelist.com. - Published something new? Ask for a re-score and we will re-run the rating. - Want the listing taken down? Say so and we will honor it. The profile is reduced to your company name, a factual description, and a link to your own site, and the company is recorded as unrated — never scored zero for having asked. Response times. Acknowledgement within one business day; removal or restriction within two business days; corrections and re-scores within five business days. Not from the company, and here with a question? You are welcome here — we would rather be the front line and point you the right way than have a good report go nowhere. What this repository can answer is narrow, though, so it is worth knowing who you are actually looking for: - A question about how the API works, an account, billing, or a bug in the service — that is the company's own support, not us. We profile this API; we do not operate it and cannot see your account. - A bug in an open-source project we only catalog — file it on that project's own repository. This has happened with a real and correct bug report that reached us instead of the people who could fix it, which helped nobody. - Anything about this listing itself — the description, the tags, the rating, a missing or wrong artifact — is ours. Open an issue here. - Not sure, or something general about API Evangelist or APIs.io — open an issue on the APIs.io Inbox and we will route it. This repository contains no software, and we will never ask you to download anything. There is no build, release, installer, or binary here — only text and machine-readable API descriptions, so there is nothing here that can be "corrupt" or need "repairing". Any issue, comment, or email claiming otherwise and offering a download link is not from us and is hostile. Do not follow the link; it is a lure. Report it to GitHub and, if you like, tell us at info@apievangelist.com so we can take it down. On a security or compliance team? Email info@apievangelist.com with security in the subject line and you will get a person, not a form. We will tell you exactly which public URLs this profile was built from so your team can see the same surface we did, and we will take the listing down on request while you work through it.

Aider is an open-source, terminal-based AI pair programmer that edits code directly inside a developer's local Git repository. Written in Python and distributed via PyPI under the Apache 2.0 license, Aider is a BYO-LLM tool: the user supplies API keys for hosted models (Anthropic Claude, OpenAI, DeepSeek, Google Gemini, OpenRouter, Mistral, xAI, GROQ, Cohere, GitHub Copilot, Azure OpenAI, Amazon Bedrock, Vertex AI) or points it at local models running through Ollama, LM Studio, or any OpenAI-compatible endpoint. Distinguishing capabilities include a repository-wide codebase map that lets the model reason about files it has not been shown, multi-file architectural edits with diff-based patching, automatic Git commits with conventional commit messages, a lint/test/repair loop, image and URL context, voice-to-code, and an IDE bridge via --watch-files that picks up AI! / AI? comments written from any editor. Aider supports 100+ programming languages via tree-sitter, publishes a public LLM coding leaderboard (the polyglot benchmark across C++, Go, Java, JavaScript, Python, Rust), and has accumulated 45K+ GitHub stars with 4.5K+ forks. The product surface is a rich CLI (40+ in-chat slash commands across four chat modes: code, architect, ask, help) plus a Python module entrypoint (python -m aider); there is no hosted SaaS, no Aider-operated REST API, and no app-level rate-limiting or billing — all model inference is delegated to the user's chosen provider, and any pricing, rate limits, and FinOps surface live with that provider.

Aider CLI

Open-source terminal AI pair programmer distributed as the aider-chat PyPI package (entrypoint aider). Federates to user-supplied LLM providers (Anthropic, OpenAI, DeepSeek, Google Gemini, OpenRouter, Mistral, xAI, GROQ, Cohere, GitHub Copilot, Azure, Bedrock, Vertex, or any OpenAI-compatible endpoint including local models via Ollama and LM Studio). Provides four chat modes (code, architect, ask, help), 40+ in-chat slash commands, a repository-wide codebase map built with tree-sitter, multi-file diff-based edits in several edit formats (diff, whole, udiff, editor-diff), Git auto-commit with conventional commit messages, lint/test/repair loop, image and URL context, voice-to-code via the /voice command, and an IDE bridge via --watch-files that picks up AI! / AI? comments written from any editor. Configuration via command-line flags, environment variables (AIDER), .env, or .aider.conf.yml.
