Felix Krause open-sources FxLifeSheet life-tracking dashboard

FxLifeSheet is the ultimate expression of the "quantified-self" movement, proving that personal data ownership is the only way to get true longitudinal insights without platform lock-in.

• –Aggregates over 380,000 data points across 100+ categories including health, location, and digital activity
• –Uses a custom Telegram bot (FxLifeSheet Bot) for frictionless manual data entry of subjective metrics like mood and stress
• –Built on a modular stack of Ruby, Postgres, and Plotly.js, allowing for deep correlation analysis (e.g., how weather affects productivity)
• –Strictly self-hosted philosophy ensures sensitive life data remains under the user's control rather than a third-party cloud
• –Open-source MIT license allows other developers to fork and customize the tracking logic for their own needs
