Elmo vs Lantern
Elmo is an open-source, self-hostable alternative to Lantern, 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.
The short version
Lantern doesn't list Microsoft Copilot or Grok among its engines and has no MCP server or sentiment analysis. Elmo has all of that, and it's free to self-host.

Why choose Elmo over Lantern?
Open source and transparent
Every line of code is open. You can verify exactly how your visibility data is collected, calculated, and presented. No black boxes.
Self-host for free, forever
Run Elmo on your own infrastructure. The core platform is free and always will be, and Elmo Cloud is there if you would rather not run it yourself.
Your data, in your stack
Pull every metric, sentiment included, into your own code with the REST API and TypeScript and Python SDKs, or ask Claude Code and Cursor about it over MCP. Export, fork, or migrate at any time.
Built to last
Bootstrapped and sustainable. No investors pushing towards dark patterns. We'll outlast the companies taking too much VC money.
Frequently Asked Questions
- What is the difference between Elmo and Lantern?
- Elmo is an open-source, self-hostable AI visibility platform, while Lantern is a closed-source AI visibility tracking tool.

- Is Elmo a free, open-source alternative to Lantern?
- Yes. Elmo is a free, open-source alternative to Lantern. You can self-host the full platform at no cost, read every line of code, and track your AI visibility across ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews without per-seat or per-prompt fees.
- Is Lantern open source?
- No, Lantern is a hosted product without public source code. Elmo is fully open source, so you can read how each metric is calculated, self-host it on your own infrastructure, and take your data with you.
- How do Elmo and Lantern compare on sentiment analysis, API access, and MCP?
- Elmo includes all three: a 0 to 100 sentiment score for every AI answer that mentions you, a REST API with TypeScript and Python SDKs, and an MCP server so assistants like Claude Code and Cursor can query your data.
