We built Sonde (https://github.com/compiuta-origin/sonde-analytics) after noticing - probably like everybody else - our website traffic was declining while prospects were telling us "I found you through ChatGPT".
We wanted to understand our visibility across LLM responses, as we did in the good old days of SEO and web analytics. Since existing tools were enterprise-tier expensive, we built Sonde as a simple internal project to:
- schedule prompts to run against multiple LLMs, with web search enabled - track whether your brand is mentioned in responses, how it ranks vs. competitors and general sentiment - monitor trends over time
Tech stack: Supabase, Next.js, OpenRouter as LLM wrapper.
Sonde is fully open-source and you can self-host it via Docker Compose. We're also offering a managed version for convenience, running with complete feature parity.
Sonde has fundamentally changed how we approach content strategy for our products: I'd love to get feedback on it, or hear how you're currently tracking LLM visibility!
