AI Visibility Tracking

Elmo vs Siteline

Elmo is an open-source, self-hostable alternative to Siteline, an AI visibility tracking tool. Both measure how AI answer engines describe your brand, but Elmo ships every line of code, runs on your own infrastructure, and is free to self-host — so your data stays yours and each metric is independently verifiable.

About Siteline

Siteline, previously GPTrends, measures how AI agents, bots, and crawlers move through a site: visit counts by provider, which content they prefer, where they get stuck, and human visits arriving from AI. A log explorer sits alongside visibility tracking and citation counts, plus an agent readiness check and a continuously updated directory of AI agents, bots, and crawlers. It was voted #1 Product of the Day on Product Hunt and has a free tier.

Popularity grade: C

  • Log explorer for raw agent and crawler behaviour, not just aggregate counts
  • Publishes a maintained public directory of AI agents, bots, and crawlers
  • Rebranded from GPTrends; voted #1 Product of the Day on Product Hunt
