The Copper Fern

The directory's 598 dentist profiles live in one Supabase table. The thing that saved me: Row Level Security. Public can read a profile and insert an appointment request — and that's it. Can't read other people's requests, can't edit a listing. Three RLS policies. No backend code to leak.

Tell me your LA neighborhood and I'll reply with the highest-rated dentist on the directory. Beverly Hills, Encino, El Segundo, Silver Lake, Studio City, go. go.thecopperfern.com/yourhood

"Deep cleaning" gets recommended a lot in LA. Sometimes it's needed. Sometimes it's upsell. Rule of thumb: if you've never been told you have gum pockets >4mm, ask why now. A second opinion is cheaper than a scaling you didn't need.

Solo dev, no QA team. My safety net is one rule: every change goes through a branch and a PR, even when the only reviewer is me. Writing the PR description forces me to explain the change, and half my bugs get caught in that paragraph. That discipline is what ships the directory.

I'm doing a Build in Public series for a dentist directory in LA. It's going to help both the customers and the dentist in the area. I'm going to make a promise to make it ad free forever. That way it's a very clean, smooth, design forward experience. I do need some eyes on it though to test. Let me know if there are any pitfalls that you see and try to break anything.

Good Morning SaaS Founders!🧑‍💻 • Drop your SaaS, let’s get some users to try it out.👇

@siya_twt_ I was a plumber for the longest time and I don't think AI is going to be able to replace that for a long time but maybe they can come up with an AI poo sniffer??

Name a career that Al can't replace

@0xPrajwal_ I think there's a time and place for both but session is definitely easier to maintain. Check out my project and let me know which one you would recommend that I use. Maybe you have a better opinion. go.thecopperfern.com/replies

As a Dev, what would you choose for your app authentication? - JWT - Session And why? 🤔

@muskaan___07 I'll definitely recommend Reddit to everyone. It's the greatest because it's moderated, friendly, community-driven. Also if you're searching for something, if you include the word reddit at the end of it, you'll get very good responses.

Name one app you recommend to everyone

@droidbuilds Ha ha, that has to be the greatest feeling for WinRar and the worst feeling for the client when they realize it's absolutely useless to pay for

Name best tech company to ever exist. I'll start : WinRAR

LA people: what neighborhood do you need a dentist in? Reply with it and I'll send back the top-rated one on the directory + what they're known for. No charge, no catch — I'm stress-testing the data.

Open question for the builders, devs, and creators here. I'm a solo dev shipping an LA dental directory in public. The whole thing runs on a deliberately small stack: • Claude Code for the building • Supabase for the database, auth, and storage • GitHub + Hostinger for version control and push-to-main deploys • Typefully for this feed That's it. Every tool on that list had to earn its spot by saving me more time than it cost me to learn it. But I know I'm missing things. There's a whole category of tools I've never tried, simply because I never had a reason to, until someone whose work I respect says "this one's actually different." So, two questions: 1. What's in your stack right now that genuinely earns its keep? Not the hyped one. The one you'd be annoyed to lose. 2. Is there a tool you've been curious about but haven't had time to test? Drop it here. I'll put it through a real build on the directory and post an honest review: what it's good at, where it lied to me, whether it's worth the money. No affiliate links, no sponsorships. Just a solo builder kicking the tires so you don't have to. What should I test first?

The directory has had zero paying practices since launch. I'm not panicking. Week one is for making the thing useful enough that a local actually finds a dentist on it. Useful first, charge second.

I didn't hand-write the dentist search. I described it to Claude Code — "filter 598 profiles by neighborhood, specialty, insurance, instant" — and watched it wire the query, the UI, and the empty states in one pass. Then I spent the real time fixing the 10% it got wrong. That ratio is the whole job now.

@TommiPedruzzi Claude is the bomb

Delete Tiktok Delete YouTube Delete Instagram You can make $3,000/month using Claude to build Digital assets. It’s boring... but if you start today, you could make $3,000 by the end of July. I’ll send you a free training showing exactly how to do it. Just like this post and comment “Claude.” (Make sure you follow.)
