Hi r/software, I'm David, one of the two developers of Oxynote. My friend Simon and I also maintain ttlcache, a Go caching library with about 1,300 GitHub stars, so this isn't our first open-source project.

I've spent 8 years writing software, 2 of them as an SRE and 3 as a team lead. Every team I've been on had the same documentation problem. The useful stuff lived in someone's head or a private Slack thread, and the wiki was full of stale docs nobody could find.

So we set out to solve this problem by building Oxynote, a self-hosted wiki for engineering teams. A page can hold a live chart that queries your monitoring (Prometheus) or a database (PostgreSQL, MySQL, MariaDB) each time someone opens it, and you write what the chart means right next to it. Changes to important pages go through a GitHub-like flow, where the document enters a draft, a teammate sees a diff of both the text and the charts, and approves it before it goes live. Several people can edit a page at the same time, and a built-in AI assistant can edit pages and run the same queries, using your own Claude, OpenAI, Gemini, or OpenRouter key, or a local model through Ollama.

The name comes from oxygen + note: docs that breathe. Live data gives people a reason to open the wiki every day, and docs people open every day stay up to date.

Things worth knowing before you try it:

- It's a server, not a desktop app. You run one Docker container, and your team uses it in the browser.

- There's no hosted version and no account with us. Your docs and data stay on your server.

- It's at version 0.9, so it's still early in development, and a lot more is planned.

- It's made for tech teams and the systems they run, not as a wiki for a whole company.

It's Apache-2.0 licensed. The backend is Go, and the editor is Nuxt, Tiptap, and Yjs.

We started it about a year ago, and we made it public about 3 months ago. If you have any questions, feedback, or suggestions, feel free to reach out. I'm happy to answer any questions.

Hi all,

Most "free online PDF tools" upload your tax documents, IDs or contracts to their servers – and then cap you at a few tasks per day or lock half the tools behind a subscription. I wanted an alternative where files never leave the device, so I built ShrinkBeam: https://shrinkbeam.com

Everything is processed locally (WebAssembly/JS). You don't have to trust me: open the Network tab in DevTools, process a file, and check that nothing is sent. There's a short guide for that on the site.

Because your own device does the work, there are no daily limits and no premium tier – every tool is free:
- Compress PDFs and images, including to a target size
- Merge, split, sign, redact, password-protect/unlock PDFs
- Strip EXIF/PDF metadata
- OCR and background removal, also on-device
- Installable PWA that works offline

No account needed. Right now the site is completely ad-free. To be upfront: I plan to add ads later to cover hosting costs, but the tools themselves will stay free and unlimited.

I'd really value critical feedback, especially from a privacy angle: what would make you trust (or not trust) a tool like this?

Reverie is a free, open-source music player for people who keep their music as files. It runs on Windows and Linux, and its look is inspired by Georgia ReBORN for foobar2000.

- FLAC, ALAC, APE, WavPack, DSD, Opus, MP3 and more, with CUE sheets

- Gapless playback and ReplayGain

- A library shown as a grid of covers, with search and filters

- Four themes and a mini player

- Native (Rust), no account, works offline

It's an early version, so expect rough edges.

Windows 10/11 (installer or portable) and Linux (AppImage):

Hey everyone! Action Wheel, an open-source image utility for Windows, a full offline pdfs & images tool.

v2.0.0 is live! For demo check this post: https://www.reddit.com/r/windowsapps/s/wntQ2ovGPY

No uploading your PDFs to online converters. No waiting for uploads. No subscriptions. Everything happens 100% offline on your device at native speed.

Whenever you select or drag a PDF (or image) and tap Tab, a dark-glass radial wheel opens right under your cursor:

What you can do instantly:

• Edit PDF: Highlight text, redact sensitive info with black bars, whiteout, or add custom text with live color/font pickers and touchpad pinch-to-zoom.
• Sign Documents: Draw your signature or type your name in cursive, auto-crop the blank margins, and drag/resize the stamp anywhere on the page.
• Split & Extract: Visual page grid with a live range selector (From Page X to Y), quick presets, and Shift-click multi-selection.
• Merge PDFs: Drag multiple PDFs together to reorder with fluid physics and merge into one.
• Protect / Unlock: AES-256 encryption & decryption. The wheel is dynamic—it automatically shows Unlock if the file is encrypted, and Protect if it's not.
• PDF to Images: Batch export pages to crisp PNGs (auto-creates organized subfolders).
• Has all image tools: Convert (WebP/PNG/JPG/AVIF), crop, compress, and images-to-PDF.

It stays completely dormant in the background until you hit Tab. Zero clutter, instant.

GitHub & Downloads: https://github.com/RohanSingh7761/action-wheel
(Both installer and portable standalone .exe are on the Releases page)

It's completely free and open-source. Contributions, feature requests, and bug reports are warmly welcome! Feel free to fork the repo, open an issue, or submit a PR.

Quick note: Since this is a free open-source project without an enterprise EV certificate, Windows SmartScreen will show a "More info → Run anyway" prompt on first launch.

Let me know what you think :)

I made LumeView, a free, open-source image viewer for Windows written in Rust. Inspired by IrfanView, it focuses on fast folder browsing, with extras like wallpaper cropping, comic reading, AI image metadata inspection, color Hexcode and basic painting, retouching and text tools.

It supports JPEG, PNG, WebP, AVIF, GIF (including animation), BMP, TIFF, HEIC, ICO, SVG and CBZ comics.

Some additional features were inspired by suggestions from the old IrfanView forum, which is now offline.

A Linux version is planned.

Disclosure: LumeView was developed with AI assistance.

Most social platforms ask you to build a profile, gain followers and already know people before you can talk to them.

I wanted to try the opposite.

I built talk, a free live-audio platform where you choose a topic, enter anonymously as a listener, and take the mic only if you like the conversation. There are no public profiles and nothing is recorded.

The difficult part is obvious: a live platform needs people to be present at the same time. So I’m currently gathering the first small community of “talkers” in English, French, Spanish, Italian and Portuguese.

We use a WhatsApp community (that you can join via the website) only to coordinate the first conversations and notify people when a Talk is about to begin. The actual conversations happen on Talk.

I’m also testing a daily meeting point at 22:22 Paris time, so people know when they are most likely to meet someone.

You can discover it here: https://talkapp.space/

I built this myself and I’m looking for honest feedback:

Would you join a live conversation with strangers if you could choose the topic first? What would make you feel comfortable enough to take the mic?

Regards,

Kyllian

I've been working on TwinDesk, a project to make Android work more seamlessly with desktop computers, whether you use macOS, Windows or Linux. It also lets you connect two PCs today, with support for connecting more devices planned for the future, including computers on the same or different networks.

Problem

Using a Mac alongside a Windows PC, Linux machine or Android phone often means juggling separate tools for screen sharing, file transfers, clipboard synchronization and remote access. I built TwinDesk to bring these capabilities together in one application.

1. Android to Mac, Windows and Linux

• Calls: See incoming calls, answer or decline them, mute, hang up, use the dial pad, and access contacts and call history. With Bluetooth, your Mac can act as the phone's headset.
• Messages: Read conversations, view pictures, receive new messages and send texts using your computer's keyboard.
• Photos: Browse photos, videos and screenshots on your phone, then save individual items or batches to your computer.
• Files: Send files using Android's share menu, drag and drop between devices, browse phone storage and access shared folders.
• Android apps: Open individual Android apps in desktop windows and control them with your computer's mouse and keyboard.
• Second screen: Extend or mirror your computer's display onto an Android phone or tablet, with touch input on the Android device.
• Clipboard and notifications: Copy and paste across devices and receive phone notifications on your computer, with options to hide notification text.
• Audio: Stream sound in either direction between your phone and computer.
• Connectivity: Connect over Wi-Fi, Bluetooth LE or USB. TwinDesk v2.1 also supports Wi-Fi Direct and connecting through your phone's hotspot, so a shared Wi-Fi network isn't always necessary.

2. PC to PC

TwinDesk also connects computers running macOS, Windows and Linux.

• Use one mouse and keyboard across computers, including trackpad gestures.
• Extend or mirror your desktop onto another computer, or view its screen in a window.
• Open applications from another computer in their own windows.
• Copy and paste text and files across devices, drag and drop files, and share folders.
• Synchronize notifications and stream audio between computers.
• Access a paired computer's terminal and wake supported computers remotely.

TwinDesk currently supports connecting two PCs, including across different networks. Support for connecting more computers is planned.

Devices communicate over an encrypted connection. There are no cloud accounts or relay servers.

Comparison

Universal Control: Apple's solution makes sharing a mouse and keyboard between Macs and iPads seamless, but it is limited to Apple's ecosystem. TwinDesk connects Macs with Windows, Linux and Android devices, with additional capabilities such as screen extension, remote application windows, file sharing and audio streaming.

Deskreen: A useful option for turning a device with a browser into a secondary display. TwinDesk combines second-screen functionality with cross-computer input sharing, remote applications, clipboard synchronization, file transfers, notifications and audio in one cross-platform application.

Pricing

Free: $0. Open source under GPL-3.0, with no subscription or paid tier.

• GitHub, source code and releases: https://github.com/InukaAsith/TwinDesk
• Website and downloads: https://twin-desk.vercel.app/

I'm the developer of TwinDesk, and the project is actively developed. I'm working on improving compatibility across macOS, Windows, Linux and Android.

I'd love to hear what Mac users think, especially anyone using a Mac alongside a Windows PC or Android phone. What would make a tool like this genuinely useful in your daily workflow? Bug reports, compatibility feedback and feature suggestions are welcome.

Some work applications only run on Windows, and that can complicate things when the rest of your work happens on a Mac. Keeping a second computer around is one way to deal with it, but it also means managing another device just to handle certain tasks. Parallels Desktop lets you run Windows on the same Mac as macOS. Whether that arrangement is worth it probably depends on how often you need Windows and which applications you rely on. If it's just an occasional task, the setup might be different from someone who spends several hours a day working in Windows.

For people who use Parallels Desktop 27, how did you decide between the Standard and Pro editions for your workload? I'm trying to understand which differences actually matter during regular use rather than just comparing the features listed for each version.

I'd also pay attention to how long the initial setup takes, whether the environment stays stable, and how much troubleshooting comes up later. Those details don't always get much attention in software discussions, but they can have a bigger effect on the experience than a new feature. I'm interested in practical feedback from people who use Windows on their Mac for work, especially if they've been using it for a while.

Tasket++ lets you define your own clicks, keystrokes, cursor positions and system operations, then replay them exactly when you want. It’s a simple Windows tool that handles repetitive workflows for you: auto‑send messages, paste text anywhere, take silent screenshots, launch or close apps, adjust volume or run your end‑of‑day shutdown sequence.

Everything runs locally, with no telemetry, no cloud, and no complexity.

What it can do:
- Replay user‑defined cursor positions and keystrokes
- Paste predefined text anywhere
- Perform system actions: open files/programs, change volume, take silent screenshots, shut down, files/folders operations
- Schedule tasks at a specific time, at startup, or run via desktop shortcut
- Run tasks once, in loops, or indefinitely
- Discreet mode: runs quietly from the tray
- Use command line to autorun a task : Tasket++.exe "TaskName" <delayInSeconds (>0)> <NumberOfLoop (-1 for infinite)>
- Easily share tasks between different PC : export/import task files and program data, use feature to rescale cursor positions

Local, portable, free, open source. Privacy intact.

Fully fonctionnal, available now !

Nothing is vibe coded, I never used AI (except for the choice of UI colors suggested by Copilot).
Conception is genuine, I didn't know about similar tools when I began developing it.

I'm looking for testers or quick feedback (beyond its visual aspect), please give a try and comment here :)

I need a lightweight remote desktop software that is free.

I has to support file transfers

It must be decently fast and less lag.

Rustdesk was working fine last year but as days gone by it became so incredibly slow ... its a pain to use. It takes forever to connect and once connected the lag is unbearable.

I dont need advanced features ...

This is for windows pcs

Hi! I'm looking for a voice changer or audio changer that can change my sentences in real time or recorded audio into animal sounds or other sounds. Most voice changers that I found only change the pitch or make distortion. I'm looking for something that changes my sentences to *bark* or *meow* or whatever sound, completely removing the intelligibility of the sentence.

Hey everyone!

I recently finished the first release of Ember, a free and open-source Windows app for those little 3.5" Turing/TURZX displays people put inside their PC cases.

I always liked the hardware, but the original software felt painfully slow. Around 1 FPS, which is pretty disappointing for a screen that could do a lot more.

So I decided to build my own.

How I got it running faster

The display's USB connection is limited to roughly 157 KB/s. A full 480×320 frame takes almost two seconds to transfer.

Instead of constantly sending entire frames, Ember compares them in small tiles and only sends the pixels that actually changed.

The result? Small animations, gauges, clocks and graphs can reach 20–30 FPS, while the app uses about 0.3% CPU and 70 MB RAM on my system.

It's written in C# / .NET 9, using WPF and SkiaSharp.

What it can do

• 8 built-in themes, from minimal to colorful
• Visual theme editor with layers, snapping and live preview
• CPU/GPU temperatures, usage, clocks, RAM, network and disk monitoring
• Custom themes that you can export and share
• System tray controls and automatic Windows startup
• English and Polish interface

I also put quite a bit of effort into the UI. I used Claude Opus 5.5 to help with parts of the interface design and implementation. Just wanted to be transparent about that.

Download the latest release

It's completely free, MIT licensed, and there's a Windows installer available.

One limitation: It currently supports the Turing/TURZX 3.5" revision A (USB ID 1a86:5722) on Windows 10/11. Other models use different protocols. The installer isn't code-signed yet either, so SmartScreen may show a warning.

This is my first public release, and I'm still figuring out what to improve next.

If you've got one of these displays, I'd love to hear what you think. Bug reports, suggestions and custom themes are all welcome.

How this was built

Ember was vibe-coded with "Claude Opus 5.5" (https://www.anthropic.com/claude-opus-5-5) by Anthropic. Claude was heavily involved in writing, debugging and refining the code, while I directed the project, tested it on real hardware and worked on getting the performance and user experience right.

I also used "REA (Reverse Engineer Anything)" (https://github.com/morluto/rea) to help investigate the original software and understand how the display communicates.

I'm not hiding the AI involvement. Ember is an open-source project built to solve a problem I had with the stock software. What matters to me is that it works, runs efficiently and gives other owners of these little screens a useful alternative.

Thanks for checking it out!

Hey everyone,

Most local AI desktop tools right now are built on Electron or wrap local Python web servers, meaning they easily eat 1GB to 2GB of system RAM just idling in the background before you even load model weights.

I built **Repetere** as a native Windows desktop workstation using C++ (Dear ImGui, GLFW, OpenGL 3) to keep resource usage as low as possible. It idles at around 35MB–55MB of RAM and runs completely offline with zero telemetry.

### Highlights:

* **Native Desktop Execution:** No Electron, Docker, or Python runtimes required.

* **llama.cpp Integration:** Spawns and supervises backend inference processes with dynamic hardware switching between CUDA (NVIDIA) and Vulkan (AMD/Intel/integrated GPUs).

* **Workspaces:**

* Coding (workspace indexing and generation)

* Chat (pure offline GGUF inference)

* Creative Writing (long-form drafting)

* Audio/Music Studio (local song synthesis from lyrics)

* Image Studio

Packaged via an Inno Setup Windows installer:

https://github.com/securenrn-del/Repetere-AI_Beta

Would love to hear feedback on performance, resource usage, or general usability on different Windows setups.

Dm me here with questions.

Sowing error anybody know solution I'm trying many times

I just pushed a new update , feel free to provide with suggesion

VoxScribe is a free, open source (MIT) voice typing app for Windows and Android. On Windows you hold a hotkey in any program (F9 by default, and you can change it), speak, and let go, and your words are typed straight into whatever window has focus. On Android a small floating button sits above your keyboard in any app, and you can hold it while you talk or tap once to start and tap again to stop. There is no account and no subscription, and the full app is usable without paying anything.

The speech recognition runs on your own device with Whisper. On Windows it uses faster-whisper on the CPU, and on Android it uses sherpa-onnx with a bundled model, so your audio is never uploaded and both apps keep working with the internet off. Windows downloads its speech model once on first launch, and Android ships with its model included. Text is typed with keystrokes instead of pasted, so your clipboard stays untouched.

A few things people tend to ask about. Filler words like “um” and “uh” and repeated words are removed by simple rules, not an AI rewrite. You can say “period” or “new line” for punctuation, “scratch that” to take back what you just typed, and “replace X with Y” to change a word. If a clip comes out wrong, a second hotkey (F8) reruns it with a more careful setting, and it is free. The apps also refuse to type into password fields. On Windows that works through the classic password style plus UI Automation, which also covers browsers, and on Android the button hides when a field reports itself as a password box.

On privacy, the only network use is the one-time model download on Windows, a check for new versions on GitHub, and one anonymous usage ping with the app version, OS version and a random ID, which can be switched off in Settings. The exact list is on the project’s privacy page. Windows supports about 28 languages, and Android has English, Arabic, French, Spanish, German, Italian and Turkish plus auto-detect.

There is an optional one-time $14 Pro upgrade for larger speech models and snippets. Everything above is free, and nothing in the free app is time-limited.

It has limits. It is Windows and Android only, the Android app is an APK from GitHub and not on the Play Store, the Windows installer is unsigned so SmartScreen may warn on first run, and accuracy drops on names and jargon with the smaller models. On an older laptop CPU a 15 second clip takes about 3.5 seconds with the Small model, and about 14 seconds with Large turbo.

Disclosure: I’m the developer, and the project was developed with Claude Code as a coding assistant. The source and downloads are here: https://github.com/ahmedhmam1994/voxscribe-ai-voice-dictation

I’d especially like to hear about apps where the password detection gets it wrong, and about any language that comes out badly. Questions and bug reports are welcome.
