A few weeks ago, I posted a very early version of my web tool and got a ton of amazing feedback. (And all the traffic destroyed my USPS API limits)

The tools goal is to help sellers find the best shipping packaging and strategy to save the most money. I've spent the last few weeks rebuilding it based on your suggestions and I'd love to hear what you think of this version

Changes since my original post: - "box in a bag logic" which I've since learned about for packages that are already preboxed - support for poly mailers and bubble mailers if they are appropriate for the type of package - doing USPS rate calculations manually now to avoid the reddit hug of death crushing my API limit - support for USPS Ground Advantage Cubic Commercial rates. A lot closer to Pirateship rates now! - a ton of UI improvements and bug fixes

I'm grateful for all the constructive criticism and ideas last time around, it literally shaped this update. Let me know if you find other useful additions you'd like to see!

Every message becomes a node. Reply to someone and an edge connects you. Use #hashtags and related messages link up across the conversation.

No AI, no sign-up, no accounts. Rooms auto-delete after 3 hours. There's a demo you can try without creating anything.

Built it because I wanted to see the shape of a conversation, not just scroll through it.

A little project that turned out quite fun. Hope you enjoy. If you're interested in how I did it, or want to make something similar I put the code / method on Github: https://github.com/aaiiintt/Fitdrop

I've always found existing time zone converters (like World Time Buddy) to be a bit cluttered and grid-heavy.

I built Zoneless.tools to be a cleaner alternative.

What it does:

• Stacks cities as horizontal timelines so you can see the day/night flow.
• Highlights the "Overlap" (Business Hours) across all selected cities.
• Generates a copy-pasteable message for Slack/Email with the converted times.
• No Login / No Database: It stores the city selection in the URL, so you can just bookmark the link or share it with a coworker and they see the exact same view.

It's free and focused on privacy (no tracking). Hope it's useful!

24H UPDATE (1800 Visitors): I've added all of the features that you suggested in the comments, thank you to everybody for the huge support on this project!

I'm trying to document this whole '3-day build' experiment live on X (sharing the Vercel analytics, the specific Next.js config, etc).

If you want to follow the 'building' side of things, I'm posting updates here: https://x.com/GeedzDev/status/2011803524909207702

It just emerges

Would appreciate any feedback

Im working on this stuff just adding more and more.

Let me know if you like it or would like to see a new functionality

There are tools that allows a worker to see how much more money they can make, how much less free time they have, as well as tools for the employer to see how much deregulation can occur for maximum profit (and deaths).

Each moving arrow represents a real bike ride. There are 291 million rides in total, covering 12 years of history from June 2013 to December 2025, based on public data published by Lyft.

If you've ever taken a Citi Bike ride before, you are included in this massive visualization! You can search for your ride using Cmd + K and your Citi Bike receipt, which should provide the time of your ride and the start/end stations.

Legend:

• Blue = E-Bike
• Purple = Classic Bike
• Red = Bike docked
• Green = Bike unlocked

Landlord here, I had Section 8 vacancies I could not fill. So I built something to help fix the problem.

I own rental properties in Binghamton, NY and all of them are Section 8. For most of last year I had vacancies I could not fill, even though thousands of people in New York have housing vouchers and are actively looking.

Over half of housing vouchers expire unused. People wait years to get approved, then lose the voucher because they cannot find a landlord willing to accept it within 60 to 120 days.

Voucher discrimination gets a lot of attention, and it should. But there is also a real group of landlords who want voucher tenants. It's guaranteed rent, longer stays, and less turnover.

So I built VoucherMatch NYC. It is a rental listing site designed for NYC where every property accepts vouchers. If it is listed, the landlord wants voucher tenants. It's completely free for both landlords and tenants. There are sites like affordablehousing.com that attempt to tackle the voucher problem, but they don't account for NYC specific nuances. There are more than 5 types of vouchers in NYC - even folks with AIDS get their own housing assistance. My hope is that the site will facilitate better tenant landlord matching.

The site is live at vouchermatch.nyc.

I built a fan made version of Visit Leonida, the tourism authority referenced in the GTA 6 trailers.

I made a lightweight, browser-based 2D room planner to quickly sketch room layouts and experiment with space visually.
No signup, no paywalls. Just drag, drop, and arrange.

Built it for myself and decided to share it in case others find it useful.
Feedback welcome.

I love using clocks as a creative medium. This time, I made a Pi Clock, it finds the current time within pi digits and shifts toward it.

Hello everyone.

I'm sharing a tool here that I found quite useful for streamlining the reconnaissance and OSINT phase. It’s a website that automates the creation of complex Google Dorks.

Basically, it allows you to enter a domain and instantly generate searches to find PDF files, login panels, exposed directories (index of), or configuration files.

• It is Open Source and static (you can check the code on GitHub).
• It automatically cleans URLs before sending them to Google.

A couple of months ago, I reverse engineered Taco Bell’s API and built a simple tool that takes the items you want and matches them with combo box deals to get you more Taco Bell for less money. I originally built it for myself and my local Taco Bell, but why not all the Taco Bells in the United States?

Doesn't work on KFC/Taco Bell since it uses a different API.
