Building production SaaS entirely on Cloudflare Workers – Lessons learned

I ve been developing my SaaS platform built fully on Cloudflare Workers edge infrastructure.

Edge computing offers huge benefits for solo founders: zero idle server costs and global low-latency performance.

However, I ran into many undocumented hurdles during development:

  • Auth.js adaption issues for edge runtime

  • Tricky differences between wrangler dev and production environment

  • Stripe webhook validation & Resend email domain DNS configuration

Building an app — it's a travel guide but kind of a game too

Hey, first time here already seeing some really cool stuff on this platform.

Honestly kind of inspired seeing everyone grinding to make their ideas real.

Trying to validate an idea

Hey PH community

I'm a solo founder from Barcelona. I have this idea that I'm calling a social restaurant discovery app for international travelers (although it can be for locals as well).
What's the problem I have encountered (and talk with friends and family that they have as well):

Most of us, we are discovering restaurants from Instagram reels and TikTok, we might save them or share them in a group chat, but then it gets messy. Maybe one of us saved the location on Google Maps, just to discover that the Restaurant its on the other end of the city from where you are when you're hungry. Also, in places like Japan, Korea or China, the best and most local places are in the local language, so you need to look in Google Maps in Japanese, Chinese, or Korean (which with ChatGPT is simpler). But all this, in my opinion, it s still messy.
Also, maybe you want to find a new restaurant in the city, we all have that foodie friend that we as for recommendations, but maybe they are not available when we need them (it can happen, they have a life haha), so why not simply go check something that your friend has been to and has rated highly?

How do you keep your LinkedIn posts from sounding like everyone elses AI content?

There's a pattern on LinkedIn right now that's hard to miss. Every other post opens with a one-line hook, follows a numbered list, and ends with "What would you add?" You can tell within two sentences whether someone used AI or not.

The problem isn't AI writing it's that most AI tools have no idea who you are. They generate from a blank slate every time.

🚀 I realized AI can build software faster than ever.

I realized AI can build software faster than ever. It still can't tell you if anyone actually needs it.

Over the past few months, I've been building FounderMind AI, and one lesson kept repeating itself.

I built CourseNest to fix how people learn and find jobs

I've been frustrated watching people spend months on courses that don't lead anywhere. They learn random skills, can't interview for roles, and miss job matches that actually fit their new abilities.

So I built CourseNest. It uses AI to create personalized courses based on your goals, identifies skill gaps, and builds custom curricula. You get realistic interview practice with real-time feedback, and as you level up, it matches you with roles aligned to what you've actually learned.

One platform. Learn, practice, land.

Finally, A Smarter Way to Solve Magic Sort with AI-Powered Gaming Tool

If you've ever spent 20+ minutes stuck on one of those challenging Magic Sort Puzzles, you know how frustrating it can be. Most players end up making random moves, restarting levels, or searching for walkthroughs that don't even match their puzzle.

That's exactly why I built AI Magic Sort Solver.

Instead of relying on generic solutions, our tool analyzes your exact game board. Simply upload a screenshot, and the AI detects the tubes, colors, and special game objects to recreate your puzzle.

From there, you can:

Why Startup Accelerators Suck and Why I'm Building an Alternative

Hey everyone, I'm Javier, a digital marketer turned website developer. I've been building Creatives Takeover for the last couple of months.

Here's what got me started. I went through an accelerator myself, and beyond the fundraising connections, I walked away wondering what I'd actually gained. A cohort, a demo day, advice that sounded great in a room and fell apart back at my laptop. Nobody handed me a roadmap and even less the full journey.

Local-only submittal package concept — looking for contractor workflow feedback

I m a software developer validating a local-only product concept. I m not claiming to be a contractor, and the product is not available yet.

I m testing whether small specialty contractors would value a one-time US$59 browser tool that combines only the PDFs they choose on their own device, lets them order sections and add project fields, then generates a cover, table of contents, bookmarks, and page numbers. No account or document upload is proposed. The page has a clearly fictional sample and a fixed-choice anonymous survey; it collects no contact details or files.

I would especially value feedback from people who make submittal packages in electrical, HVAC, roofing, plumbing, or similar specialty work:
