After months of work, I just dropped v2.0.4 of Umbrella Spoofer, a Windows tool for masking hardware identifiers. Complete rewrite of the UI, engine, and driver support.

a Windows tool for masking hardware identifiers. Complete rewrite of the UI, engine, and driver support.hat it does: Changes MachineGuid, BIOS serial, BaseBoard serial, MAC address, CPU identifier, GPU identifiers, volume serials, TPM identity, SMBIOS/UUID, disk serials, EFI boot, ARP cache, install date, USB/HID device serials, and registry timestamps. Every session picks from 20 coherent hardware profiles (Dell+Intel+NVIDIA, ASUS+AMD+Radeon, etc.) so your identity looks realistic.

What's new in v2.0.4:

• Complete premium UI redesign — glass-morphism dark theme, rounded corners (Win11 snap support), snow particles, animated switches, glow buttons
• SMBIOS UUID binary patching — UUID now changes in WMI (Get-CimInstance)
• 20 pre-built coherent identity profiles (Surface Pro, ROG Strix, Razer Blade, ThinkPad, etc.)
• Registry timestamp normalization (anti-forensic)
• Install date + ProductId randomization
• 445+ USB/HID/Battery device serials patched per session
• Kernel driver for disk serial interception + CPUID hook (opt-in, HVCI-safe)
• Full dark tray menu with Quick Spoof shortcut
• Faster boot (async init)

What's free: Everything. No paid tiers, no telemetry, no ads. Built with C# WPF + C++ native helper + optional kernel driver.

Live overview, active queries, WAL rate, locks, and more.

I’m actively developing more features and older version support.
Would love your feedback and suggestions!

I don't know about you, but my Downloads folder has always been a disaster zone. PDFs, memes, installers, zip files, random images – all just sitting there in one giant pile. Every few weeks I'd open it, sigh, and spend 10 minutes manually dragging stuff into folders. Then a few days later it would be chaos again.

I looked at existing file organizers, but most of them either wanted a subscription, tried to upload my file names to some cloud, or were just way too heavy for something so simple. I wanted something that:

• Runs silently in the background (system tray)
• Automatically sorts new files by type (images, documents, archives, installers)
• Never sends a single byte of data off my machine
• Is open source so anyone can check what it's doing

So I built Mouzi 🐭🧹

It's a tiny desktop app (~5MB) built with Tauri and Rust, so it's ridiculously lightweight. It watches your Downloads folder, and whenever a new file appears, it moves it to a subfolder based on its extension. Images go to Images/, PDFs to Documents/, installers to Installers/, etc. You can also create your own custom rules.

Key things:

• 100% local – no cloud, no telemetry
• Open source (MIT) – GitHub repo here
• Silent – lives in your tray and doesn't bother you
• Undo – every move is logged, you can revert with one click
• Free, obviously

It's early stage, but it's already keeping my own machine sane. I'd love to get some feedback from this community – especially around what features would make this genuinely useful for you. Does this solve a real problem, or am I just scratching my own itch?

We’ve been building OpenLoomi, an open-source AI work companion for people who live across too many work apps.

GitHub: https://github.com/melandlabs/openloomi

My problem with the AI is that there's just too damn many scattered informations for me to deal with everyday.
There's emails.
There's calendar.
There's docs.
There's X.
The painful part is they have their own AI, which is driving me crazy because I'm still jumping back and forth between all these apps.

So I decided I need my own AI workspace that can just work as a hub for everything and also remembers what's important.

OpenLoomi is our attempt to solve this problem:

• connects to messaging, email, calendar, docs, project tools, RSS, etc.
• builds memory around people, projects, decisions, and follow-ups
• can run scheduled tasks and use skills
• runs as a desktop app on macOS / Linux / Windows
• is local-first and open source

We’re still early, and I’m trying to learn which workflows people actually care about.

Any feedback on the README, positioning, or first-run experience would help a lot.

I made a TUI app using meszmate/zigzag for following daily tech news from GitHub, Product Hunt, HackerNews, arXiv, and any custom RSS feeds you want to follow.

I hope you find it interesting.

Use the project from the github repo here: https://github.com/RareSense/Nova3D

It's free. But you need to BYOK (bring your own API key - Gemini recommended).

I've been building this because I was tired of AI generators producing detailed 3D objects where all parts are combined into a single mesh. Trying to separate parts has an impact on the shape. It starts breaking + the surface quality gets damaged because of the mesh structure. It's very cumbersome to work with.

I believe my project has deep usefulness as a "world building" tool within video games or AR/VR experiences.

If you have a feature in mind, please open an issue on my provided github.

Under the hood:
My tool uses an LLM as a structured code compiler (instead of an image generator). It writes native Blender Python code blocks that target specific nodes in the scene graph. The trick is that everything compiles through Blender's actual scene graph structures instead of pixel or point-cloud diffusion. Final export is a clean multi-part GLB with transform nodes and working pivot axes preserved.

Hi everyone,

I've created a project called "Foundry OSD", and I would like feedback from people who deal with Intune or Autopilot in real environments.

Foundry OSD is an open-source Windows OS deployment toolkit built as a C# / WinUI 3 desktop app. It helps create ISO or USB deployment media, boot into WinPE, configure Ethernet or Wi-Fi networking, and prepare a machine before the rest of the provisioning flow.

This started as a personal project because I needed a simpler way to handle the steps that still happen around bare-metal prep and provisioning. I know there are already open-source options, but I personally wanted a 100% free and open-source tool that could be very simple to use while still allowing deep deployment customization when needed. I would like to see whether Foundry OSD can become useful beyond my own use case, so I am trying to collect practical feedback.

In practice, the workflow is:

• automate ADK install/upgrade when needed
• build ISO or USB deployment media
• reuse cached Foundry OSD binaries, OS, and driver pack content on USB media across deployments
• boot into WinPE
• validate/select Ethernet or Wi-Fi networking
• choose OS, driver pack, Autopilot profile, and deployment options from automated catalogs

After several months of work, it feels ready enough to show outside my own setup. Feedback from Intune and Autopilot admins is welcome, especially around real-world pre-provisioning and bare-metal scenarios.

Discord lets you download all your data, but it arrives as an unreadable ZIP of CSVs and JSON. Most viewers crunch a few stats and stop. I spent the last few days building one that actually turns the ZIP into a full viewer for everything inside it.

The part I'm proudest of is the share card — your headline numbers, activity timeline, peak day, and a fun fact pulled from your data. One click to download, landscape or portrait. Preview in the repo.

Also in the app:

• Every DM, group chat, and server channel, fully browsable
• Media gallery with filters and a lightbox
• Search across the whole archive or inside one chat
• Stats page with peak hour, longest streak, year-by-year activity, and a trophy for your first message

Runs entirely in your browser. The ZIP never leaves your machine.

Repo: https://github.com/baairon/discord-package-explorer

What I actually care about: feedback on the UI/UX. I tried to make it feel as native to Discord as possible and I want to know what landed and what didn't. A GitHub star would mean a lot if you find it useful.

Honestly the most fun part was looking at my own data — you can see exactly how much more active I was during COVID vs now.

KoBar is an open-source, modular productivity widget designed to keep your essential tools accessible at a glance. It operates as a lightweight, always-on-top overlay so you can manage tasks without disrupting your main workflow.

It features highly customizable modules, a clean UI, and quick-access utilities. Built with versatility in mind, it gives users full control over their desktop environment without unnecessary clutter.
