About Which Agent Should I Use? (Agent Showdown)

Which Agent Should I Use? answers one question: which AI agent should I use for this? It lists coding agents, browser agents, voice agents, research agents and agent frameworks.

Every listing records where its pricing came from and when it was checked. If a price couldn't be confirmed on the official site, the listing says "See site" instead of guessing.

Listings live in one JSON file and change through pull requests. The Featured / Sponsor slot on the home page is a placeholder.
