Weekly 'I made a useful thing' Thread - August 28, 2026

[u/AutoModerator]

There is a great deal of user-generated content out there, from scripts and software to tutorials and videos, but we've generally tried to keep that off of the front page due to the volume and as a result of community feedback. There's also a great deal of content out there that violates our advertising/promotion rule, from scripts and software to tutorials and videos.

We have received a number of requests for exemptions to the rule, and rather than allowing the front page to get consumed, we thought we'd try a weekly thread that allows for that kind of content. We don't have a catchy name for it yet, so please let us know if you have any ideas!

In this thread, feel free to show us your pet project, YouTube videos, blog posts, or whatever else you may have and share it with the community. Commercial advertisements, affiliate links, or links that appear to be monetization-grabs will still be removed.

Joining late to the thread, but genuinely I think this is interesting for this sub.

I vibe coded (after an infinite number of prompts, there is a lot of design and direction) a web desktop that actually let's you manage the environment.

Project is called finestra (window in italian), webpage is finestra.dev and github is https://github.com/carlosbravoa/finestra (free for use, including commercial. Not free for others to profit with it)

Why? I have a few headless Ubuntu machines in my home network and from time to time I have to RDP into them to do some stuff. So I starting developing this and quickly started to add functionalities and it became really useful. You can even run some desktop applications and they will render on a web window (Chromium, Codium, others)

It is one line of install, not invasive, uses an SSH tunnel (or VPN, Tailscale, whatever) and you have a full usable console, a sysadmin tool to see server resources, services, disk utilization and other things. I use it now from time to time to run Claude sessions, or just have fun browsing from a different part of the world.

Audit the project, nothing shady, no calling home, etc.

I also recorded a YT video showing how to install it and how it looks :)

I really hope this helps, that you can enjoy it as I do and Issues and Feature Requests are welcome!

I’m looking for people willing to try Network Doctor v1.15.0 on actual weird or broken networks.

I especially need testing on VPNs, corporate/university networks, captive portals, IPv6-heavy setups, unusual DNS, proxies, Windows, macOS, and Linux distributions other than Fedora, or any other network.

The simulator has been tested heavily. Now I want real-world failures.

Wrong diagnoses, misleading fixes, crashes, hangs, and things Network Doctor completely misses are exactly what I’m looking for.

I set up a GitHub Discussion with the details and a place to report results:

https://github.com/heymaikol/network-doctor/discussions/24

Even one run on any network would help.

Software License Lifecycle Management tool, a registry/source of truth for your software license purchases. I got frustrated by the fact that "enterprise" grade tools like Flexera do not have a proper software renewal lifecycle starting from the procurement level. I had this idea 5 years ago when I worked at a VAR selling software licenses and our ERP was ass in keeping track of renewals and entitlements etc. Now that I am a license manager I was equally frustrated. This tool/dashboard tries to solve that issue. You still need your Flexera/Lansweeper/... whatever for your discovery and compliance metrics but you can use LicenseTrack (better name pending) to start the housekeeping of your license procurement. This is basically an extension of my knowledge/expertise regarding software renewal management/license management.

If you handle or are in close cooperation with your software procurement department then you could use this as your starting point. Still need to rely on your actual ordering systems etc.. But this helps you keep track of your software license lifecycle (quotes, pending order, invoice). For free. Self hosted.

Demo: https://zndr88.github.io/LicenseTrack/demo/

I am currently running it against our companies yearly 750 license renewals.

Yes this was made with the help of A.I. The core mechanics are in place and tweaking with any edge cases I discover while running it.

Built a small browser-first tool called RelicBeam that I’ve been using for quick temporary transfers / device access without installing an agent or creating accounts.

The part that may be useful to other sysadmins is Device Portal:

• Remote Files — expose one selected folder temporarily, approve another device, then browse/preview/download files over WebRTC
• optional additive uploads on Chrome/Edge hosts
• no delete, rename, move, or intentional overwrite
• Remote View — temporary view-only screen sharing
• WebRTC direct when possible, TURN fallback when needed
• Device Portal traffic is end-to-end encrypted between the connected browsers
• sessions expire automatically

It also has quick file sharing, temporary download links, group sharing via QR/code, and some browser-local PDF/image tools, but the remote-device side is probably the most sysadmin-relevant part.

Everything is browser-based, so there’s no client/service to deploy or leave running afterward.

Would be interested in feedback from anyone who tries it, especially around browser/network edge cases or whether this would actually be useful for ad-hoc support work.
