Echo vs Xofu
Echo is an open-source, self-hostable alternative to Xofu, an AI visibility tracking tool. Both measure how AI answer engines describe your brand, but Echo 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
Xofu doesn't list Perplexity, Claude, or Microsoft Copilot among its engines and has no API or MCP server. Echo has all of that, and it's free to self-host.
Echo
Open-source AEO platform. Self-host for free, forever. Track AI visibility across ChatGPT, Claude, and Google AI Overviews with full transparency.
Xofu
Bottom-of-funnel prompt tracking with entity audits
About Xofu
Xofu deliberately narrows to the prompts buyers use when shortlisting vendors — best X for Y, vendor comparisons, solution evaluations — across ChatGPT, Google AI Overviews, AI Mode, and Gemini, tracking recommendations over time. Citation gap analysis shows which sources get cited when competitors appear and the brand does not, prioritizing pages to improve and publishers to target. It ships a snapshot report and an entity audit, free to start with no card.
Popularity grade: C
- Scoped to bottom-of-funnel shortlisting prompts rather than all mentions
- Citation gaps returned as a publisher target list
- Standalone entity audit alongside the tracker

Why choose Echo over Xofu?
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 Echo on your own infrastructure. The core platform is free and always will be, and Echo 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 Echo and Xofu?
- Echo is an open-source, self-hostable AI visibility platform, while Xofu is a closed-source AI visibility tracking tool. Both track how AI answer engines describe your brand, but Echo gives you the full source code and runs on your own infrastructure, so you can verify every metric and keep your data in-house.
- Is Echo a free, open-source alternative to Xofu?
- Yes. Echo is a free, open-source alternative to Xofu. 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 Xofu open source?
- No, Xofu is a closed-source, hosted product, so you cannot inspect how its metrics are calculated. Echo is fully open source — you can audit the code, self-host it on your own infrastructure, and avoid vendor lock-in.
- How do Echo and Xofu compare on sentiment analysis, API access, and MCP?
- Echo 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. Xofu offers sentiment analysis, but we have not found it offering API access or an MCP server.
- Can I self-host Echo instead of Xofu?
- Yes. Echo is designed to be self-hosted — deploy it on your own infrastructure in minutes with the CLI. You keep full ownership of your data and prompts, with no per-seat pricing and no third-party dashboard holding your visibility history.
