Show HN: Stackzero - The Smarter Way to Discover Free Developer Tools
Stackzero is a web platform that catalogs and ranks free developer tools across 15 categories. It scores each tool on six criteria and normalizes the results to a 100-point scale, allowing users to filter by free‑forever, no credit‑card, and TLS requirements. The interface supports sorting, multi‑column comparison, and head‑to‑head tool analysis.
- ▪Stackzero indexes 97 free developer tools spanning categories such as PaaS, DBaaS, CI/CD, and LLM APIs.
- ▪Each tool receives a score from 0 to 10 on six axes—Generosity, Scaling, DX, OSS Friendly, Unlimited, and Depth—and the total is normalized to a /100 rating.
- ▪Users can apply filters like "Free forever" and "No CC" to view zero‑friction tools and compare up to four tools side by side.
- ▪The platform provides a head‑to‑head comparison mode that highlights differences in pricing friction, developer experience, and open‑source friendliness.
