Welcome back to Projects of the Week, our weekly look at some of the most interesting products coming out of the ** Proof of Usefulness Hackathon**.
The bar is pretty simple: build something people actually find useful. Every project featured here tackles a real problem, whether that's through better infrastructure, smarter automation, or a fresh take on an old workflow.
This week, three more projects made the cut. From photo restoration and multi-agent orchestration to framework-free frontend components, each one tackles a problem people run into all the time - and offers a practical way to fix it.
⏰ The Clock Is Ticking: 3 Days Left to Enter
The Proof of Usefulness Hackathon closes on August 10 — just 3 days from now.
If you've got something built, this is your last call to get a Proof of Usefulness score, land a spot in a feature like this one, and compete for the prize pool before submissions close for good. Don't wait until the deadline to find out your project was ready all along.
Meet the Projects of the Week
Image to Photo
Image to Photo is an online tool that effortlessly enhances and restores old or damaged photographs. Using advanced algorithms to sharpen detail, correct color, and rebuild texture, it helps people turn faded, damaged memories back into something worth sharing. It's built on Next.js for a fast, SEO-friendly experience, and its early users span families restoring heirloom photos, photographers polishing portfolios, historians digitizing archives, and artists reviving old work.
At around 500 users so far, the project is still in its early, foundation-laying stage — but the use case is timeless: everyone has a box of old photos they wish looked the way they remember them.
Proof of Usefulness score: +28 / 1000
Granary
Granary is an open-source CLI built to solve one of the most annoying problems in modern AI development: agents that lose context, duplicate work, or step on each other's changes when running on the same codebase. Granary fixes that with session tracking, task orchestration, concurrency-safe claiming, checkpointing, and structured handoffs between agents — all local-first, shipped as a single Rust binary, and compatible with any agent framework.
Built on Rust and SQLite for speed and safety, Granary is aimed squarely at developers running multiple LLM coding agents on real projects. It's already picking up real momentum: 260 average daily views over the past week, 84 upvotes on Product Hunt within a day of launch, and early open-source traction with GitHub stars and contributors rolling in during its first week.
Proof of Usefulness score: +88 / 1000
Nexio
Nexio is a growing library of framework-free, ready-to-use UI components built entirely with plain HTML, CSS, and JavaScript — no React, no Vue, no build step required. It's aimed at beginner developers learning the fundamentals, freelancers working under tight deadlines, and teams that need lightweight components without dragging in a framework's worth of dependencies.
With 30+ components shipped and growing through YouTube demos and community sharing, Nexio's early users have responded well to its free starter pack, praising the code quality and how easy it is to drop straight into a project. As more developers look to escape framework bloat, Nexio's bet on "just HTML, CSS, and JS" feels well-timed.
