Overview
Aider is a command-line tool that pairs an LLM with your codebase to start a new project or change an existing one. It maps the entire repository, works with over 100 languages, and commits each change to git with a written commit message. It can also lint and test after edits, take images and web pages as context, and accept spoken instructions.
- Best for
- Developers working in the terminal who want an LLM to edit code in an existing git repository.
- Pricing
- The captured page shows no pricing at all; it covers installation via pip and passing your own LLM API key.
- Runs on
- macOSLinuxCLI
Strengths and trade-offs
Strengths
- Connects to most LLMs, including local models
- Maps the whole codebase to work in larger projects
- Auto-commits to git, so changes can be diffed and undone
- Lints and tests after edits and fixes what they flag
Trade-offs
- Terminal-first; the IDE route is comments in code, not a UI
- Needs your own LLM API key, so model costs sit on top
- Best results are tied to a handful of named models
- Using a web chat LLM means copy-pasting code by hand

How this score is made up
Each dimension is scored out of 100 and combined into the headline score using fixed weights.
MCP support
Whether an agent can drive the product through the Model Context Protocol, and how much setup that takes.
API quality
Public API surface: machine-readable spec, official SDKs, documented auth, errors, rate limits and versioning.
Documentation
Publicly reachable docs — coverage, freshness, code samples and machine readability.
Agent friendliness
How readable the site is to an automated client: llms.txt, structured data, server-rendered content, crawler access.
Changelog
A public, dated record of what shipped and when — the clearest signal that a product is still alive.
Marketing site structure
Whether the site answers a buyer's questions: clear positioning, the pages that matter, and accessibility.
Page speed
How fast the site loads for real visitors: Chrome UX Report 75th-percentile LCP, INP and CLS, with a Lighthouse mobile run standing in where a site has too little traffic for field data.
Operational trust
Status page and incident history, security disclosure, compliance and data-processing documentation.
Measured, but not part of the score
Useful to know, but not a mark for or against the product — so these do not affect the ranking.
Openness
Source availability, self-hosting, data export and open standards. Scored and shown, but not part of the composite — paid SaaS is not worse for being paid SaaS.
Maintenance
Release cadence and repository activity. Scored and shown, but not part of the composite — it is only measurable for open repositories.
