About Kitze

Kitze is a developer, YouTuber, conference speaker and serial indie maker known for building opinionated tools for developers and productivity nerds. His best-known product is Sizzy, a browser for web developers that shows a site across many synchronized devices at once and has grown to include workspaces, isolated sessions, terminals and coding agents.

He built Benji, an all-in-one 'Life OS' for tasks, habits, routines, journaling, workouts and nutrition, because he needed it himself, and has openly discussed how his ADHD shapes the way he juggles many projects. His public portfolio lists well over a dozen products, including the Zero To Shipped web-and-mobile boilerplate, the Sotto dictation app for macOS, Supermac, DMX (a time-boxed X client), Glink (feedback boards and changelogs), gifs.so and Flavors.

In 2025 he launched Tinkerer Club, a lifetime-access community for people who automate their lives, run local AI and self-host their stack, which brought in more than $220K of verified revenue in a single 30-day period. He runs several YouTube channels, speaks at JavaScript conferences about moving from 'vibe coding' to 'vibe engineering', and shares his launches and numbers in public.

Ship many small, focused apps instead of one sprawling product.
Own your stack: self-host and avoid endless subscriptions where you can.
AI agents are powerful, but engineering discipline still matters.
