Hey HN! I built TopicRadar to solve a problem I had with staying on top of what's trending in AI/ML without checking 7+ sites daily.

https://apify.com/mick-johnson/topic-radar

What it does: - Aggregates from HackerNews, GitHub, arXiv, StackOverflow, Lobste.rs, Papers with Code, and Semantic Scholar - One-click presets: "Trending: AI & ML", "Trending: Startups", "Trending: Developer Tools" - Or track custom topics (e.g., "rust async", "transformer models") - Gets 150-175 results in under 5 minutes

Built for the Apify $1M Challenge. It's free to try – just hit "Try for free" and use the default "AI & ML" preset.

Would love feedback on what sources to add next or features you'd find useful!

I built a simple tool to compare hard drive and SSD prices by price-per-terabyte.

I kept having to calculate $/TB manually when shopping for NAS drives, so I made this to save myself the trouble.

It pulls prices from Amazon (US, CA, AU, and EU stores), calculates $/TB, and lets you filter by drive type, interface, form factor, and capacity.

Nothing fancy — just a sortable table updated daily.

Any feedback is more than welcome, I hope someone will find it useful!

Built Figr AI because I got tired of AI builder tools market themselves as design tools and end up skipping the hard part.

Every tool I tried would jump straight to screens. But that's not how product design actually works. You don't just design screens. You think through the problem first. The flows, the edge cases, the user journey, where people will get stuck. Then the design comes finally.

Figr does that thinking layer first. It parses your existing product via a chrome extension or takes in screen-records, then works through the problem with you before designing. Surfaces edge cases, maps flows, generates specs, reviews UX. The design comes after the thinking.

It is able to do so because we trained it on over 200k+ real UX patterns and UX principles. Our major focus is on helping in building the right UX by understanding the product.

The difference from Lovable/Bolt/V0: I think those are interface builders. They are good when you know exactly what you want to build but they don't truly help in finding the right solution to the problem. Our aim with Figr is to be more like an AI PM that happens to also design.

Some difficult UX problems we've worked through with it: https://figr.design/gallery

Would love feedback, especially from folks who've hit the same wall with other AI builder/design tools.

I been building a view into companies based on their job postings. I am hoping it is useful to get a quick snapshot on the company say for interview prep etc. Please be advised that it is still a WIP in terms of data quality.

Hi HN,

I built this because I often work in coworking spaces or do screen sharing, and I've always had this fear of accidentally flashing my .env file with production secrets to the whole room (or recording).

It’s a simple VS Code extension that opens .env files in a custom grid editor. It automatically masks any value longer than 6 characters so I can safely open the file to check keys without exposing the actual secrets.

It runs 100% locally with zero dependencies (I know how sensitive these files are). It just reads the file, renders the grid, and saves it back as standard text.

It's open source (MIT) and I'd love any feedback on the masking logic or other features that would make it safer to use.

Hello :-)

I have a Discord server I set up a long time ago. Around 2016 I think. Back then, it was lively and active and loads of fun. Over time it's developed close to 5,000 members (it actually had over 5,000 members at one point) and currently has 501 members online as I type this. It's more likely there's about 10-15 that are paying attention to anything happening.

It's a Discord that originally focused on DevOps. It complemented my YouTube channel on the same topic, but since then, as it's slowly died out, and my channel's focus as shifted and changed, it's become a bit of a waste land.

It's a shame really, because a really fun Discord server can be a great place to be, but I'm not sure where to take it now.

How would you handle this situation? What would be your approach to reviving the Discord and perhaps trying to get a community of like minded hackers going again in 2026?

I won't link the Discord here as I'm not trying to beg for users or spam. I just genuinely want to work on a solution to improve the life of the server. I will put it in my HN profile, though, so if you do want to check it out that extra step is required.

Are people even interested in Discord servers any more? I don't know.

Thanks in advance.

This is just a goofy thing I cooked up over the weekend. It's kind of like a screensaver, but with more reading and sliders. (It's not terribly efficient, so expect phone batteries to take a hit!)
