I've been working on a "businesses for sale" aggregation/search engine that sources data from all of the major "business for sale" type platforms in Australia and de-duplicates listings, extracts data like revenue/profit/etc, and normalises it all for quick browsing. I have a couple of family members and friends who are looking to buy businesses (separately), and it's been much more time-consuming than you'd expect j…

If it’s anything like the US, the listings only represent a minority of what’s available for sale and buyers are better off hiring a broker. If you could find a way to have majority of everyone actually list things for sale online, I think you’d have a solid business.

I'm building ClosedLinks, a tool for sharing files and/or messages anonymously through one-time access links with no traceable sender. Most digital tools assume persistence; ClosedLinks is built for ephemerality and unlinkability. Each link is single-use, redirects on access, and stores encrypted content only temporarily. Recipients never see the original URL, enabling plausible deniability. Think: whistleblowers. En…

Cool, I've been working on similar my self. Not released yet, haven't had the time recently.

Curious as to why you store the data in the database in b64 as opposed to files on disk. What's the reasoning for that? Doesn't it make storage/backups/etc more complicated?

Not an expert myself, I opted for in browser encryption, in chunks, so as to avoid memory limitations (at least in some browsers, not FF yet), and in browser gzip so as to keep file size down and speed things up.

I find your niche quite interesting (journalists, whistleblowers) but given the high stakes of that perhaps an open source or more collaborative approach would be easier to promote.

Another idea I've tried out but not pursued, is some sort of browser extension/addon (I used nwjs, similar to electron), that offers client side encryption for any site (form field really). So you'd only post encrypted stuff to whatever service (email, reddit, hn, whatever) and only anyone with the key would get to read it (well, assuming they have the key and the same extension). Just throwing the idea out there, I'm sure others have thought about something along those lines before. The details to get it right are tricky (UX wise), but for your target audience it may be well worth the extra work.

Keep it up!:)

I am working on a time tracking app for tasks. I built it because I want to gain a better understanding of how I spend my working days. It's meant to be very simple. Everything is stored locally and requires no login. I don't currently plan to sync it with any backend. This isn't something that can be used to track employees — it's just for personal use. https://www.zookeeper.fyi/

it's somehow on a block list in ublock. Hence white screen here too, I have to disable adblock to see your site. Maybe the domain used to be for something else before.

I'm working on Zen Notes - a minimal, distraction-free notes app that prioritizes ownership and longevity.

The core philosophy is: your notes should be yours forever, that also includes the software stack it's built on. Everything is stored locally in SQLite with standard Markdown, so no vendor lock-in or proprietary formats. The interface is very minimal without flashy colors or icons, so you can focus on your thoughts.

Key features: instant full-text search using BM25, flexible tag organization instead of rigid folders, rich Markdown support with formatting toolbar, and custom "Focus Modes" for different contexts. It's a PWA that works offline (read-only).

The tech stack prioritizes minimal dependencies - no NPM (self-hosted Preact instead of React), Golang for rich standard library, etc. The whole app can be run from a single binary, so no messy installation requirements. Docker is also available.

I tried to design this from scratch, learning about typography, colors, spacing etc. It turned out better than I expected!

I've switched to this as my main notes app and I'm happy with it.

Have you ever wanted to write your life story but found it too overwhelming? I’m developing an app that acts as your personal interviewer, guiding you through your memories and helping you share them with your loved ones. The app is designed for older adults who enjoy reminiscing but struggle to organize their thoughts into a coherent narrative. The goal is to preserve their hard-won insights and pass them down—to fa…

Would love a link to the demo if and when you’re open to sharing. I’m a product designer but not looking for projects, I’m mostly curious - this is one of the more unique ideas I’ve heard.
