Hey Product Hunt 👋

Runlight is free, open source web analytics that lives inside your app.

I run a lot of sites, and every new launch meant another analytics account, another third-party script, and another monthly bill. Analytics felt like something my apps should handle on their own, so I built Runlight to do exactly that.

You install it like any other package, add one route and one script tag, and every visit gets recorded in the database you already have (SQLite, Postgres, MySQL, MariaDB, Turso, or D1. Clickhouse support is there too!)

The script is under 2 KB, posts to your own domain so ad blockers leave it alone, and sets no cookies. No cookie banner, nothing personal stored, no third party to trust with your visitors. It shows you:

Who’s on your site right now
Where visitors came from, grouped into search, social, email, campaigns, and AI
Which visits came from ChatGPT, Claude, Perplexity, and Gemini
AI agents and crawlers reading your pages, even though they never run JavaScript
Goals, conversions, and the revenue behind them, along with visitor journeys
Clicks on short links you create on your own domain

It works with TypeScript, PHP, Python, Ruby, Go, Java, .NET, Elixir, and Rust, and plugs into Next.js, Rails, Laravel, Django, Phoenix, and a bunch more. There are also plugins for WordPress, Drupal, and Craft CMS.

A few extras I’m happy with:

A one-page dashboard that mounts in your app at /runlight
Weekly or monthly email reports sent through your own email provider
An MCP server so Claude or Cursor can answer questions about your stats
A setup prompt you can paste into your coding agent to wire it all up

And it’s free and open source, MIT licensed. Code’s on GitHub: https://github.com/runlightsh/runlight

I’d love feedback, issues, and PRs.

If your stack isn’t supported yet, tell me which one. Thank you :)
