Lioncore

Softwarepeopleactually use every day.

Every tool I build starts from a real problem, mine or someone I've met along the way. Lioncore apps, extensions and automations come out of trying to help, concretely.

Frequently asked questions.

Because I run into these problems myself, or meet people who do. Every Lioncore product starts from a real, day-to-day frustration: if I can solve it cleanly with code, I turn it into a tool so others can benefit too.
