A directory you can check.

What this is

There are dozens of AI coding tools now, and the categories are easy to mix up. A harness is the runtime that talks to a model and runs tools. An orchestrator is an app that runs one or more harnesses. A cloud agent works in a hosted sandbox and hands back a pull request. An add-on is a plugin or distribution that extends one harness or orchestrator.

Each tool has one page with the facts that matter when you choose: who makes it, what it runs on, how you pay for it, and which features are confirmed. The same facts power the comparison matrix and the tier-list maker.

How to read a tool page

Features have three states, and the third one is the important one:

? means nobody has checked yet. It is not a polite way of saying no. We write ✗ only when a source confirms a feature is missing, and every page lists the sources used for that entry.

Pricing and platform facts change often. Each entry carries a last verified date, and GitHub star counts carry their own check date.

Neutrality

There are no paid rankings, sponsored placements or affiliate links. Order in the directory is alphabetical, tier lists belong to the people who make them, and no tool can buy a better position.

Taglines describe what a tool does, not how good it is. Comparisons show the same rows for every tool so the format cannot favour one entry.

If the project ever accepts sponsorship, it will be labelled clearly and kept away from rankings and comparisons.
