self-hosting posthog means clickhouse, kafka, redis and a postgres. this is one binary.

If you want product analytics you can actually run yourself, the options are bad. PostHog is a stack: ClickHouse, Kafka, Redis, and a Postgres to babysit. Plausible and Umami install easily but stop at web analytics, so no funnels, no retention, no cohorts.

smolanalytics is the middle that didn't exist. One Go binary, one data file, no external database. It does web analytics (visitors, referrers, UTM, devices) and product analytics (funnels, retention, paths, cohorts) from the same events, plus feature flags, A/B testing, click heatmaps, in-product surveys, a session inspector, and deploy-impact. Cookieless mode means no consent banner. MIT, free forever, and your data never leaves your box.

It also answers in plain English, from the dashboard or from your editor over MCP, using your own model, so the AI part costs nothing.

Open localhost:8080: a fully populated dashboard, a "what to fix" verdict up top, and an ask bar with your real events and pages as one-click chips. Nothing to configure. Prefer not to install? The live demo is the real product on demo data, running right now.

Ask your analytics where you write code

This is the point of the whole tool. smolanalytics is an MCP server, so your coding agent queries your real analytics without you leaving the editor. It has your codebase, your tracking plan, and smolanalytics over MCP, so it answers in your terms: ask "what's the MAU for the PQR page" and it knows PQR is the /pqr route from your code. Your model does the reasoning, so there are no API keys and nothing metered.
