What is Evidence?
Evidence is an open-source, code-based business intelligence tool that lets data teams build polished reports, dashboards and data products using just SQL and Markdown. It takes a refreshingly different approach from traditional drag-and-drop BI: instead of clicking through a GUI to build charts, you write SQL queries and Markdown, and Evidence renders beautiful, interactive data reports — bringing the benefits of software engineering, like version control, code review and reproducibility, to analytics and reporting.
The workflow is elegant for technical analysts. You write SQL to pull and shape your data, then write Markdown with simple components to lay out narrative text, charts, tables and interactive elements. Evidence turns this into a clean, professional web report or data app that updates as your data does. Because everything is code, your reports live in a git repository — they can be reviewed, versioned, tested and collaborated on like any software project, which brings rigor and maintainability that point-and-click BI tools struggle to provide.
This code-first philosophy resonates strongly with the modern, engineering-minded data community. It's ideal for building things like recurring reports, internal data products, metrics narratives and customer-facing analytics, where you want polish, consistency and the ability to manage reports as code. As open source, Evidence can be self-hosted and customized freely, avoiding lock-in, with options for easier hosting too. It fits naturally alongside tools like dbt in the modern data stack. For data analysts and engineers who are comfortable with SQL and want to build elegant, maintainable, version-controlled reports and dashboards — and who find traditional BI tools clunky or hard to govern — Evidence offers a powerful, developer-friendly and genuinely modern approach to turning data into clear, shareable insight.
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.
