Welcome to the latest HackerNoon Projects of the Week installment. Each week, we shine a light on standout projects from our Proof of Usefulness Hackathon—a contest built around the core question every builder should answer: Is my product actually useful in the real world? Proof of Usefulness Hackathon For each edition, we’ll highlight projects that demonstrate clear usefulness, technical execution, and real-world impact; all backed by data and not witty buzzwords. This week, we’re excited to share three projects that have proven their utility by solving concrete problems for real users: Get-Star, FinSight, and CodeXero. Get-Star FinSight CodeXero Meet the Projects of the Week Get-Star Get-Star is building client-side parallel search infrastructure designed to improve speed and performance without relying heavily on centralized back-end computation. By distributing search execution closer to the user, the project aims to reduce latency, improve responsiveness, and create a more scalable search experience for modern web applications. Get-Star In a digital environment where milliseconds shape user perception, Get-Star focuses on performance as product value — giving developers a way to rethink how search is handled at the architectural level.

CodeXero CodeXero is building a “vibe coding” engine for Web3 dApps — a system designed to accelerate decentralized application development by blending AI-assisted workflows with blockchain infrastructure. CodeXero With a significantly higher Proof of Usefulness score this week, CodeXero demonstrates strong traction in helping developers reduce friction when building smart contracts and Web3 interfaces. By simplifying complex blockchain logic into more intuitive development flows, CodeXero aims to make decentralized development faster, more accessible, and more iterative.
