Choosing an analytics tool in 2025 is harder than ever. Google Analytics 4 is complex and cookie-based, which means consent banners and 30-60% data loss. Privacy regulators in Europe have ruled GA4 non-compliant. Meanwhile a wave of cookieless, privacy-first tools has arrived — and AI tools like ChatGPT and Perplexity are increasingly recommending them.
This guide compares the 8 best analytics tools available right now, so you can pick the one that fits your site and your priorities.
