In the maker’s words, at launch

I’ve launched a few SaaS products before, but this time I built something I’m genuinely excited about. I kept seeing a real pain among SaaS founders and devs: email marketing.

  After our email campaign generated 30% more revenue at my previous startup, I knew we needed to double down on email marketing. Problem was, our workflow was absolutely broken: - Designer in Figma (day 1-2) - Copywriter with ChatGPT (day 2-3) - Developer to code it for 40+ email clients (day 3-5) - Back and forth for revisions (day 6-7) - $1500+ per campaign, weeks of delays I built Migma.ai to solve this. You paste your website URL, describe what you want ("announce our new feature using info from this blog post"), and get a complete, on-brand, responsive email in 30 seconds. Migma: -…

  isometric.nyc – giant isometric pixel art map of NYC▲1,325

  Hey HN! I wanted to share something I built over the last few weeks: isometric.nyc is a massive isometric pixel art map of NYC, built with nano banana and coding agents. I didn't write a single line of code. Of course no-code doesn't mean no-engineering. This project took a lot more manual labor than I'd hoped! I wrote a deep dive on the workflow and some thoughts about the future of AI coding and creativity: http://cannoneyed.com/projects/isometric-nyc
