  I made an online Webhook Tester2024 · webhook.cool · ▲43

  Hi HN! Last year, I built LocalCan app in which you can develop apps using .local domains and Public URLs. Although it allows for testing webhooks too, I wanted to give back and create a free online tool specifically for that purpose! And so, I've made Webhook.cool Simply use your unique webhook URL to send any webhook to it from services like Shopify, Slack, Mailchimp, Trello, GitHub, PayPal, Discord, and Jira. Give it a try and let me know how if you have any feedback.

  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
