AI Visibility Tracking

Elmo vs RankLens

Elmo is an open-source, self-hostable alternative to RankLens, 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.
