Free local-first tools for solo creators, indie publishers, and people who want to own their stack instead of renting it.
Single HTML files that live in your browser. Every tool here is a self-contained file you can use online or download and keep forever. No login, no subscription, no server gate. Your data stays on your machine. If I disappear tomorrow, the tools still work.
This is the opposite of how most software gets built. Most tools want your account, your data, your monthly payment, and your dependence on their server staying online. These tools want none of that. Use them, don't use them, they don't care. They just work.
New tools get added as I build them. Bookmark this page if you want to come back when more land.

A diagnostic tool that assesses your current newsletter situation across growth, engagement, and monetization, then outputs personalized recommendations. Built from a comprehensive framework that doesn't depend on any specific platform.
