TelemetryDeck is a strong contender, offering real-time, accurate and private insights into how developers can improve their apps. It's got features like A/B testing, custom dashboards, error tracking and cookieless tracking. TelemetryDeck is designed with privacy in mind, complying with GDPR and CCPA regulations, and it uses double-hashed user identifiers that don't reveal user identities. That means it's a good choice if you want to keep your data private.
Another contender is PostHog, an all-in-one analytics platform that includes product analytics, feature flags, session replays and A/B testing. It's got a lot of tools for funnel analysis, user paths and goal tracking, with dynamic cohort support and built-in surveys. PostHog is designed to be flexible and adaptable, so it's good for startups and growth-stage companies, and it's open-source so you can get involved with the community.
If you're looking for website analytics with a privacy-first approach, Simple Analytics is a good option. This GDPR-compliant service doesn't use cookies and has lightweight scripts that won't slow down your website. It's got tools for tracking goals, exploring events and exporting data, so it's a good privacy-focused alternative to Google Analytics.
