HackerNoon Projects of the Week: Flow33, Washd, and Mongo Lens

Hey Hackers!

Welcome to HackerNoon Projects of the Week, where we spotlight standout projects from the Proof of Usefulness Hackathon, HackerNoon’s competition designed to measure what actually matters: real utility over hype.

This week, we’re excited to talk about 3 projects that have been shown to be useful: Flow33, Washd, and Mongo Lens.

Meet the Projects of the Week:

Flow33

Although small businesses don’t have the budget of big corporations, they still need to focus on marketing to get their name out there. But what happens when they don’t have a big marketing budget to hire actors and a whole film crew to create ads for them? They need to think outside the box. Flow33 is here to help them do just that.

According to its website, it uses Nano Banana, GPT-4o, Veo 3.1, Seedream, and Sora 2 to help users generate images and videos. But it’s not like other AI content generators; Flow33 specializes in making its content look as professional as possible. Creating marketing material has never been easier or more accessible.

Flow33 enables anyone to create UGC-style videos, AI actor content, and visual workflows without hiring videographers or editors. Notable use case: solo entrepreneurs and small teams producing studio-quality content on a budget.

Washd

A modern invention that people take for granted are washing machines. They allow people to free up time so that they can focus on other tasks. However, washing machines don’t just appear out of thin air, ready to work. A lot of modern ones need software you can depend on. RFID-software like Washd.

If you’re running a big laundry operation, you need software to help you track and manage everything that enters your operation. You don’t want to gain a reputation for losing textile; Washd can help prevent that. Its website states that it offers textile tracking, inventory management, maintenance schedule, and a whole slew of features to keep your laundry running like a well-oiled machine.

[Washd] replaces manual processes and guesswork with real-time data, automation, and clear oversight of what’s happening, where, and why.

Mongo Lens

Phones are an amazing piece of tech that work like a miniature, even more portable laptop. However, there are still things that you can only do on a laptop. There are a lot of apps that are trying to change that, and Mongo Lens is one of the most impressive.

Mongo Lens is a MongoDB client available on phones. If something urgent requires your attention, you don’t have to rush home, scrambling to reach your laptop. Debug any issues or errors that come your way straight from your phone. The best part? Mongo Lens’ website states that it’s 100% free.

It’s especially useful for developers who need quick mobile access to their database without using a PC. Indie hackers and startup founders also use it for real-time data monitoring and editing
