Zencoder ▲766Hi HN, I’m Andrew, Founder of Zencoder. While building our IDE extensions and cloud agents, we ran into the same issue many of you likely face when using coding agents in complex repos: agents getting stuck in loops, apologizing, and wasting time. We tried to manage this with scripts, but juggling terminal windows and copy-paste prompting was painful. So we built Zenflow, a free desktop tool to orchestrate AI coding workflows. It handles the things we were missing in standard chat interfaces: Cross-Model Verification: You can have Codex review Claude’s code, or run them in parallel to see…

I created vibescaffold.dev. It is a wizard-style AI tool that will guide you from idea → vision → tech spec → implementation plan. It will generate all the documents necessary for AI coding agents to understand & iteratively execute on your vision. How it works: - Step 1: Define your product vision and MVP - Step 2: AI helps create technical architecture and data models - Step 3: Generate a staged development plan - Step 4: Create an AGENTS.md for automated workflows I've used AI coding tools for awhile. Before this workflow (and now, this tool), I kept getting "close but not quite" results…

100 Vibe Coding▲351Hi HN, I have been making side projects since I was 14, and my team mate (this is his very first side project! Congrats!) designed and implemented the UI. Over time, people kept asking me how they could start coding and turn ideas into reality. So we had an idea. Coding is changing. With AI, the bottleneck is no longer writing every line by hand but knowing how to prompt effectively to reach a working outcome. Our objective is not to make people code better, or even learn to be a proficient software engineer, but just to keep it simple and start building. We want to remove fear and barriers…
