Echo vs MentionStack
Echo is an open-source, self-hostable alternative to MentionStack, 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
MentionStack doesn't list Google AI Mode, Google AI Overviews, 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.
MentionStack appears to be a very early-stage product with limited adoption.

Why choose Echo over MentionStack?
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 MentionStack?
- Echo is an open-source, self-hostable AI visibility platform, while MentionStack 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 MentionStack?
- Yes. Echo is a free, open-source alternative to MentionStack. 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 MentionStack open source?
- No, MentionStack 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 MentionStack 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. MentionStack offers sentiment analysis, but we have not found it offering API access or an MCP server.
- Can I self-host Echo instead of MentionStack?
- 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.
