Where Django comes with an ORM, admin, and auth built in, Flask starts with almost nothing: a routing decorator and a Jinja2 template engine. You bring SQLAlchemy for database access, Flask-Login for sessions, Flask-WTF for forms, and PostgreSQL for persistence, hosted on a container platform or VPS. Every component is chosen explicitly, which makes the stack easier to understand but requires more upfront decisions.\n\nThe Jinja2 template engine is one of the most capable **server-side templating** systems available: template inheritance, macros, filters, and conditionals let you build complex layouts without writing JavaScript. Pages render on the server and are returned as complete HTML: no hydration, no client-side routing, no bundle sizes to worry about.\n\nFlask shines for small-to-medium applications where Django's conventions would feel like overhead, or for teams that want precise control over which libraries they include. It's also popular for wrapping ML models in a web interface, since the Python data science stack integrates naturally.

The dashboard is intentionally minimal, making key metrics immediately readable without training. Non-technical users occasionally need help with initial database configuration for self-hosted deployments, but the cloud option removes this friction.","Umami covers the core web analytics surface area well and supports custom events and API access. However, it intentionally avoids complexity: there is no advanced segmentation engine, no report builder, no custom dimensions beyond event properties, and no integration marketplace. Teams needing deep behavioral analysis or complex attribution models will hit its ceiling. Open-source access allows developers to extend the codebase, partially offsetting these limitations.","The 2 KB tracking script loads asynchronously and has a negligible impact on host page performance. Dashboard queries are fast on typical self-hosted hardware. A single low-cost VPS handles hundreds of thousands of monthly events without issue. The lightweight architecture is a core design principle, making it one of the most resource-efficient web analytics tools available.","With over 36,000 GitHub stars and thousands of forks, Umami is consistently cited as the leading privacy-focused open-source alternative to Google Analytics. It has broad coverage across developer communities on Hacker News, Reddit, and ProductHunt, and maintains active release momentum.
