The Agents Index is the datasheet for every AI agent: what it does, what it costs, and whether it holds under load.
The agent space moves faster than anyone can evaluate it. Frameworks, hosted platforms, coding assistants, support bots, voice agents and the infrastructure underneath them all arrive weekly, each announced with a demo video and a waitlist. Working out which of them you can actually get today, at what price, and with what limits, usually means reading half a dozen marketing pages and still guessing. The Agents Index exists to make that a lookup instead of an afternoon.
The index currently holds 95 published agents across nine categories: Coding, Support, Sales and marketing, Research and data, Voice, Agent frameworks, Agent platforms, and Agent tools and infrastructure.
Every listing is sourced and checked. We build each entry from the vendor's own material — product pages, pricing page, documentation, changelog — rather than from press coverage or a competitor's comparison table, and each entry records when it was last confirmed. Where a vendor does not publish a price, the listing says the price is not published instead of inventing a plausible one. Where a product is a waitlist rather than something you can sign up for, the listing says that too. That is the difference the name is meant to carry: a datasheet, not a launch feed.
What you can do with it: browse the nine categories, look up a specific agent and see in one place what it does, what tier it starts at, and how current that information is, and put a shortlist side by side before you commit engineering time. It is not a leaderboard, there is no ranking for sale, and a vendor cannot buy a better write-up.
Who it is for: engineers and technical founders deciding whether to adopt an agent framework or build on a platform, teams comparing coding or support agents before a trial, and anyone who needs to tell a shipped product apart from a launch announcement.
How it is built: Neact 19 and TypeScript on Vercel, with Prisma 7 over PostgreSQL (Neon), Tailwind CSS 4 and Better Auth. It is built and maintained by Matfy, a one-person team in the Netherlands, founded in 2026. The Agents Index is not open source, and it is a sister project to CitedIndex, which does the same job for AI-visibility and GEO tooling.
Pricing: being listed in the index is free forever. There is a single optional one-time upgrade of $29 that turns a listing's outbound link into a do-follow one. Nothing else is charged, and paying changes nothing about the research or the position.
