It's the time of the year again, so I'd be interested hear what new (and old) ideas have come up. Previously asked on:

I built an accounting app :

https://compta.libremen.com

Did not intend to at first, but having quit Windows, I had to replace the Access application I had built with an accountant friend of mine to manage my small business. Looking around the web, I could not find something I liked.

I ended up re-writing the thing as an SaaS for my own use, but then figured that if I'm using it, others might want to, and all I had to do was to add an 'id_client' field to the database. It turns out to be a bit more complicated than that, as users tend to come with different needs, and to think of ways of using your app you did not anticipate.

Also, when I tell an accountant that I wrote an accounting application, his eyes pop, his head tilts slightly, and he appears to be evaluating whether I'm the dangerous kind of crazy before ending the conversation. Must be due to the horrors they have to deal with all day.

It's a hard sell, revenue is closer to $500/year than $500/month, because I have very low fees and very small clients. But I take great pride in counting one accountant using it in his professional practice. It's also great fun to tune as the number of lines grows, however odd this may sound.

A platform for digital asset management, review and workflow. Current features focus primarily on review of images aimed at automotive configurators.

The problem is generic, however, our USP is we have a couple of enterprise customers that upload packs of 60k+ assets for a round, and thus we aim to help discover what demonstrably changed.

A bit like Github, only working with images, videos, and other digital assets rather than text files.

i'm solving the "sitting is new smoking" problem. Basically an app that uses your webcam and local AI models to predict if you are sitting + your sitting posture, so you don't develop neck pain.

I created Multy 5 years ago. Thanks to a post on HN at that time, it was a small success (https://news.ycombinator.com/item?id=25870504)

Since then, I continue to maintain the website and I have around 50k lists, 8k users, and around 400€ MRR (ads and subscriptions).

I'd love to see more users, but I'm glad of what I did with multy !

how do you deal with spam/abuse?

Dashboard and moderation. I created an admin dashboard to check users and lists and can easily delete / ban users.

Right now it's fine with the number of lists created per day

I have been building an iOS net worth tracker app as a side project for more than 5 years now:

https://www.percento.app

I was an accountant for 3 years before I switched my career to be a programmer, then I kept coding for 10+ years in big tech companies and had always wanted to build a product on my own. Eventually, I found the niche to combine my finance knowledge and my iOS skills into this App and happily building for a few years.

Can I share data with my partner? I’ve been looking for a way to help my partner understand where we at money-wise.
jianzong 7 days ago||
ah sorry currently there is no share data feature although I've heard this feature request from time to time, I probably should consider implementing this later. The premium membership can be shared with family members though -- one purchase for all members.

I recently exited a Shopify App which was making ~800$ MRR and just shipped my first AI Chrome extension. It dubs YouTube videos into 82+ languages and offers more controls for better youtube experience

I’d love your feedback - https://chromewebstore.google.com/detail/atlas-ai-youtube-du...

I run Packetriot: https://packetriot.com, which is an alternative to ngrok. It's been in operation for 6-ish years and reached $500/month in year two. It doesn't replace my salary (yet) but that's what I'm working toward. Thankful to have thousands of users and some big companies using our services or self-hosting our server.

This is a fun space to work in but there's lot of small competitors and opensource alternatives. In the first few years it was sometimes demotivating, but at some point I began seeing competitors bow out and Packetriot kept getting better and better each year.

This year I published a lot of updates across the platform. Our UX is better with a new web-based UI for our client and all of the features of the platform can be managed in the client UI. No more going back forth between the client and user portal.

I'm planning on releasing a community edition of our server in 2026 so that anyone can use our network server for free, for personal use or to evaluate for commercial use.

Super Fine Cuts, super low run custom "vinyl" records. I have been working on automating some processing but currently it is all manual.

Had an overwhelming response as people are finding it mostly though ChatGPT which has been very interesting as I did a soft launch to friends only and no marketing.

We're a group of developers who worked together years ago. We meet a few times a year, but scheduling is always a hassle with endless back-and-forth trying to align everyone's calendars. Frustrated by this, I built Troviamo to solve it automatically. I know similar tools exist, but this one is modern and tailored to exactly what we needed.

How's this different than the good old Doodle everyone uses in europe at least?
