Weekly 'I made a useful thing' Thread - May 22, 2026

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.

I just shipped a free DNS propagation checker and I'd love feedback from people who actually deal with DNS migrations day-to-day. Honest critique welcome like what's missing, what's broken, what would actually be useful.
A couple of fields we deliberately added that other tools skip:
TTL on every result. When a resolver returns the wrong (stale) record, the question isn't "is it broken." The question is "when will it fix itself." That answer is the TTL. Most free checkers don't show this. A red dot with 47 seconds left on the cache is fine, wait a minute and refresh. A red dot with 23 hours and 14 minutes left is a different problem. You need to know which one you're staring at.
Response time per resolver. Not every propagation problem is a propagation problem. Sometimes a resolver is slow. Sometimes the route between you and the resolver is bad. We show response time in ms for every resolver and you can sort by it. You can spot the resolver that's technically returning the right answer but taking 4 seconds to do it.
Other features: 40+ resolvers (vs. the typical 21), DNSSEC validation status, geographic map, 50+ record types supported. Zero ads, no signup.

What would you actually want from a tool like this? Anything we missed? Roast freely.
Thanks in advance!

I made a PDF editor because I'm sick of Adobe tickets, and it has a new update.
https://pdf.killertools.net
v1.4.1 has performance improvements and keyboard shortcuts mainly, on top of all the same features from before. You can add signatures and images, you can edit text, highlight, all the normal things that should be free. it's a 6MB exe.
GetITDone37@reddit
It's so fast and lightweight. Thanks! Can't stand Adobe products either.
Wish there was something like this at the enterprise level for digital signatures etc.
GetITDone37@reddit
... and there the feature is in the upper right. Duh.

I made a native macOS tool for Kubernetes debugging and maintenance.
A lot of the normal Kubernetes work I do ends up being small context switches: check context, namespace, workload, pod, logs, events, YAML, describe output, auth/RBAC, port-forward, exec, and then rebuild the same path again in another tool.
Rune is my attempt to make that flow a bit more connected in a fast local Mac app.
Some things I’m focusing on:
GitHub: https://github.com/compilererrors/Rune
Website: https://viktornyberg.com
Would love feedback from sysadmin/Kubernetes people. What workflows would actually be useful in a tool like this, and what would make you not trust it?

A PowerShell module for running scripts as the currently logged on user, or any active terminal session without having to change or retrieve their password.

This is actually really useful for automation scripts that need to run in a user context without storing credentials. Been burned by that before. The module approach is cleaner than messing with scheduled tasks or stored tokens. Going to test this out in our lab. Thanks for sharing.

I built an open-source CLI for M365 + Google Workspace tenant audit evidence packs.
Not trying to replace CIPP, Secure Score, SCuBA, or a proper security review. It’s aimed at the annoying MSP bit: collecting defensible read-only evidence, naming missing scopes/blockers, and producing a customer handoff pack with proof tables, API/permission ledgers, checksums, and validation.
Raw evidence stays local. Public audit mode is read-only. No Gmail/Exchange body reads or Drive/SharePoint/OneDrive file-content reads by design.
Free to take, opensource.

Hello, just wanted to share the app I'm working on as a solo dev to get opinions and testers! It's called Boopbeep 😄
Boopbeep is a native Swift SSH, SFTP, and database client for iPhone and iPad (and Mac natively, soon!). I built it because every existing mobile SSH app was either subscription based or didn't focus on the UI enough for my liking, and the database tooling story on iOS basically didn't exist.
What's in the current beta:
• A beautiful intuitive Liquid Glass design that fits like a glove on IOS/iPadOS 26
• Full terminal via SwiftTerm with jump host support, per-host startup commands, and custom color themes
• SFTP file browser with drag and drop, in-place editing, and remote file previews
• 8 database engines wired up: Postgres, MySQL, SQLite, MongoDB, Redis, and more.
• Schema browser, ER diagrams, query history, CSV export, read-only mode for prod
• Live host monitoring (CPU, memory, disk, load) pulled from /proc over the same SSH tunnel, no agent required
• iPadOS 26 real multitasking and windowing
• Demo mode so you can poke around without wiring up real servers
And the best part: the app's revenue model for the App Store release is no IAPs, no subscriptions, ever. Just a 4.99$ initial price and you're done, you own the app and all future features, forever.
Thanks for reading! Let me know what you think! https://testflight.apple.com/join/K9CU7k4C

I built getuserdesk.com which is a simplified front end for MS365 that you can give to power users i.e. HR, directors, maybe some managers to handle basic tasks like onboardings/offboardings, PWs, DLs/groups - just so those simple things don't have to wait on IT and so IT doesn't have to waste time on them. (also works for MSPs who have customers with a single in house IT guy so you can delegate some access w/o opening up the whole tenant)

Built an EU-sovereign identity platform as an alternative to Entra ID, Okta and Google Workspace
My background: been working for 15+ years as sysadmin, working with Microsoft enterprise solutions (Active Directory, Entra ID, PowerShell), and IAM. Based in the Netherlands. For the past few years I have been wondering why there is no real EU native IdP trying to compete with Entra ID, Okta or Google Workspace.
So I started thinking about it more and more and finally vibe-coded Totem ID over the past few months, as a proof of concept.
Link: https://totemid.dev/
What it is
The idea is to build it first as a layer on top of your existing Google or Microsoft IdP via directory sync. Transfer SSO and SCIM integrations over to Totem ID and over time, it's designed to take over as your primary IdP.
After the identity layer is solid, the roadmap is mail, storage, then a full office suite thats is good enough for most SMBs — within two years of launch. Identity first, everything else built on top of that foundation.
Feature-wise, the current proof of concept includes:
AI disclaimer
This is a vibe-coded proof of concept running on a small OVHCloud VPS. It is absolutely not production-ready and not intended for anything real yet. I built it to visualize my ideas, get something in front of people, and have something to confirm my ideas.
A senior engineer is rebuilding it properly targeting a real product release after summer.
What I'm looking for
Would you use something like this? Or what features are you missing to start using something like this? Is EU sovereignty actually a buying signal for your org, or is it just nice-to-have? What would make you switch away from Entra ID or Google Workspace?
Just looking for honest feedback.
