Hi HN! I am a indie hacker and love building apps with SvelteKit, so I built a boilerplate with the tech stack I always use. It has almost everything needed to launch a SaaS/tool/AI app, like auth, db + orm, email, payments and styling. You can view everything that's included on the website and the docs (https://docs.launchleopard.com) Would love to hear what other features or tech you'd want to see in a boilerplate like this!
