Echo vs SiteSignal
Echo is an open-source, self-hostable alternative to SiteSignal, 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
SiteSignal doesn't list Google AI Mode, Claude, or Microsoft Copilot among its engines. 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.
SiteSignal

Why choose Echo over SiteSignal?
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 SiteSignal?
- Echo is an open-source, self-hostable AI visibility platform, while SiteSignal 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 SiteSignal?
- Yes. Echo is a free, open-source alternative to SiteSignal. 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 SiteSignal open source?
- No, SiteSignal 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 SiteSignal 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. SiteSignal offers all three as well.
- Can I self-host Echo instead of SiteSignal?
- 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.
