Frequently Asked Questions
What is the best free analytics tool for startups?
Google Analytics 4 is the most comprehensive free option for web analytics. Amplitude offers a generous free tier with 10 million events per month for product analytics. Both are excellent starting points.
Do I need to worry about GDPR with analytics?
Yes. Google Analytics collects personal data and requires a cookie consent banner in the EU. Privacy-first alternatives like Plausible don't use cookies and are GDPR-compliant by default.
What is the difference between web analytics and product analytics?
Web analytics (Google Analytics, Plausible) tracks website traffic, sources, and page views. Product analytics (Amplitude) tracks in-app behavior like feature usage, funnels, and retention.
When should a startup invest in monitoring tools like Datadog?
Once you have production users relying on your product, infrastructure monitoring becomes critical. Datadog's free tier covers up to 5 hosts, which is enough for most early-stage startups.
