What's in your stack?

Plus new developer tools and discussions to get those cogs turning

The Breakpoint

Hey all, welcome back to The Breakpoint, our weekly newsletter covering everything in developer tools on Product Hunt. This edition: isolated sandboxes for your AI experiments, the ultimate designer-dev handoff flow, and an agent that handles the developer grunt work. Plus a discussion on tech stacks that cost 0 but could make millions.

The Latest

Five of the most interesting recent dev tool (or dev tool-adjacent) launches on the site. 

  • Cua lets you spin up isolated sandboxes on your Mac (or Linux) with near-native performance. It’s built for running AI agents and complex workflows without letting them touch your actual system.

  • Superflex 2.0 turns your Figma designs into real, production-ready code. It reuses your existing components, respects your design system, and doesn’t mess with your setup.

  • GitSummarize transforms any GitHub repository into clean, interactive documentation using AI. Just swap "github" with "gitsummarize" in the URL, and it generates structured docs that are actually readable

  • Exponent is a developer agent that helps you fix bugs, write SQL, and handle incidents directly from your terminal. It’s built to feel like a teammate that actually does the annoying stuff—fast.

  • HTTL Project is a VS Code extension that helps you turn your code into clean OpenAPI specs without bouncing between tools. It runs locally, plays nice with Copilot, and actually gives you realistic payloads

What’s your $0-to-launch stack?


Brandon Chen asked what people are using to build without burning cash—and the thread turned into a crash course in creative budgeting.

Some swear by Replit and Railway. Others are squeezing every free tier they can out of Netlify, Supabase, Vercel, and Cloudflare. A few still run $5 droplets like it’s 2013, and someone dropped an entire stack that costs less than a burrito per month.

No fluff, no VC budgets—just what people actually use when they’re trying to ship fast and cheap.
