Frequently Asked Questions

Can I self-host these analytics tools for free?

Yes. Every tool on this list offers a self-hosted option. Umami is MIT-licensed with no event limits, Matomo gives you full ownership of your data, and Plausible's Community Edition covers the essentials under the AGPL. Self-hosting means your analytics data never leaves your own infrastructure.

Do these tools require cookie consent banners?

Most don't. Plausible, Matomo, Swetrix, and Vemetric all work cookie-free by default, which makes GDPR compliance far simpler and removes the need for consent banners. That's a major advantage over Google Analytics, both for user privacy and for keeping your site's experience clean.

Which tool should I choose for product analytics?

For product-level insights like events, sessions, and user journeys, look at OpenPanel, Countly, or Vemetric, which combine web and product analytics in one platform. If you only need simple, privacy-friendly website stats, Plausible, Umami, or Swetrix will cover you with far less setup.
