Echo vs OpenSight
Echo and OpenSight are both open-source AI visibility tools you can self-host and audit. Echo's focus is transparent, independently verifiable tracking across ChatGPT, Claude, Perplexity, and Google AI Overviews — with white-label support for agencies and a documented methodology behind every number.
The short version
OpenSight doesn't list Google AI Mode, Gemini, or Claude among its engines and has no MCP server or sentiment analysis. Echo has all of that, and it's free to self-host.
OpenSight appears to be a very early-stage product with limited adoption.
Echo
Open-source AEO platform. Self-host for free, forever. Track AI visibility across ChatGPT, Claude, and Google AI Overviews with full transparency.
OpenSight
MIT-licensed AI visibility tracker with a free hosted tier

Why choose Echo over OpenSight?
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 OpenSight?
- Both Echo and OpenSight are open source, so you can self-host either one and inspect the code. Echo focuses specifically on transparent, independently verifiable AI visibility tracking across every major answer engine, with white-label support for agencies and a fully documented methodology behind each number.
- Is Echo a free, open-source alternative to OpenSight?
- Yes. Echo is a free, open-source alternative to OpenSight. 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 OpenSight open source?
- Yes, OpenSight is open source. Echo is open source as well and is built specifically for self-hosted, independently verifiable AI visibility tracking, so you can audit exactly how each metric is calculated.
- How do Echo and OpenSight 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. OpenSight offers API access, but we have not found it offering sentiment analysis or an MCP server.
