What is Microsoft Clarity?

Microsoft Clarity is a free behavior analytics tool that helps you understand how visitors actually interact with your website through heatmaps and session recordings. While traditional analytics tell you numbers — how many visitors, which pages, what bounce rate — they rarely reveal the why behind user behavior. Clarity fills that gap by letting you visually see what people do: where they click, how far they scroll, and watching real (anonymized) recordings of their sessions. And remarkably, Microsoft offers all of this completely free with no traffic limits, making powerful behavioral insight accessible to everyone.

The tool's core features make user behavior tangible. Heatmaps show aggregated click and scroll patterns, instantly revealing what attracts attention and what gets ignored on each page. Session recordings let you watch playbacks of individual visits, so you can see exactly where someone got confused, hesitated, or abandoned a task. Clarity also automatically surfaces insights like "rage clicks," "dead clicks," and excessive scrolling that signal frustration or usability problems. It's lightweight, easy to set up, integrates with other analytics, and uses AI to help highlight notable patterns, all without costing anything.

Microsoft Clarity is used by website owners, marketers, designers, and product teams who want to understand and improve the user experience without paying for expensive tools. The value is free, qualitative insight that complements traditional analytics: where standard analytics tell you a page has a problem, Clarity helps you see why and fix it. Because it's genuinely free with no limits, there's almost no reason not to use it alongside your other analytics. For anyone who wants to stop guessing about how visitors experience their site and start watching real behavior to improve it, Microsoft Clarity offers a powerful, accessible, and completely free solution.

What is PostHog?

PostHog is an all-in-one product analytics and "context" platform that pulls together the data teams need to understand and improve their products — usage analytics, session replays, error tracking, feature flags, experiments and more — in one place. Used by 500,000+ teams, it's become a favorite of product-led and engineering-driven companies, and it's increasingly built to feed context to AI agents too.

What PostHog is

PostHog centralizes the signals that tell you how a product is really being used. It ingests analytics, errors and business data, records user sessions, analyzes funnels, and lets you run experiments and toggle features — then lets you query all of it, even with SQL. The idea is a single "context layer" for both humans making product decisions and AI agents acting on them.

Who it's for

PostHog serves product teams, engineers and startups that want deep, self-serve insight into their product without stitching together five separate tools. Its developer-friendly, all-in-one approach especially appeals to technical teams and companies building AI-driven products that need rich context.

What it includes

  • Product analytics and data ingestion (usage, errors, metrics)
  • Session replay of real user recordings
  • Funnel and conversion analysis
  • Feature flags and A/B experiments
  • Direct SQL querying for advanced analysis
  • AI-ready architecture that provides context to agents
  • Installation wizards, CLI and SDKs
  • Integrations with Stripe, Google Ads, GitHub and more

Many tools, one platform

PostHog's biggest draw is consolidation. Analytics, session replay, error tracking, feature flags and experiments would normally each be a separate paid subscription; PostHog puts them in one platform where they share the same data. For a product team, that means you can watch a session replay of a user who dropped out of a funnel, check the error they hit, and ship a fix behind a feature flag — all without switching tools or reconciling datasets.

Data you can actually dig into

Where many analytics tools box you into pre-built charts, PostHog lets you query your product data directly with SQL, so you're never stuck when you have a question the dashboards don't answer. Combined with session replays and funnels, that depth lets teams move from "what happened" to "why" — the kind of investigative analysis that actually drives product improvements rather than just reporting numbers.

Built for the AI era

PostHog leans into a "self-driving product" philosophy: because it centralizes context across sources like Stripe, Google Ads and GitHub, AI agents can autonomously investigate issues, analyze data and recommend actions. As product teams increasingly work alongside AI, having a platform designed to give agents rich, unified context — not just show humans charts — is a forward-looking advantage.

Ship, test, learn, repeat

Because PostHog bundles feature flags and experiments alongside analytics, it closes the loop between shipping and learning. You can roll out a change to a small percentage of users behind a flag, run an A/B experiment to measure its impact, watch session replays of how people actually use it, and then decide whether to expand or roll back — all in one platform. For product teams practicing continuous, evidence-based iteration, having that whole cycle in a single tool removes an enormous amount of friction.

Why choose PostHog

For product teams and engineers who want deep, all-in-one insight without a stack of separate tools, PostHog is a compelling choice. Its combined analytics, session replay, experiments and feature flags, SQL-level depth, AI-ready design and famously generous free tier (most users pay nothing) make it a practical, powerful way to understand users and build better products — on data you fully control.
