Best Analytics for Astro (2026)

Compare the best analytics solutions for Astro. We review Plausible, Fathom, Umami, and more with privacy compliance, minimal JavaScript, and static site support.

Astro's focus on minimal JavaScript makes analytics choices important. You don't want a heavy analytics script undoing Astro's performance benefits. Privacy-first analytics that don't require cookie banners align well with Astro's philosophy. Most Astro sites are content-focused, so simple web analytics often suffice over complex product analytics.

Why This Matters

Astro sites are typically fast by default. Adding a 45KB Google Analytics script defeats the purpose. Modern privacy-focused analytics are tiny (<1KB), respect user privacy, and give you the traffic insights you need without the bloat or legal complexity.

Key Considerations

01

Script Size

Astro optimizes for performance. Plausible is <1KB, Fathom is ~1KB, Google Analytics is 45KB+. Choose lightweight options to preserve Astro's speed benefits.

02

Privacy & Cookies

Privacy-first analytics (Plausible, Fathom, Umami) don't use cookies and don't need consent banners. Perfect for content sites where simplicity matters.

03

Static Site Support

Astro generates static HTML. Analytics must work client-side. All analytics work with static sites, but some have better Astro integrations.

04

Astro Integrations

Some analytics have official Astro integrations that handle script injection. Others require manual <script> tags in your layout.

05

Self-Hosted Options

Plausible and Umami can be self-hosted for free. Good for privacy-conscious projects or cost savings at scale.
