Invio - Self-hosted invoicing without the bloat. | V1.0.0 Release

Hey r/opensource , today I’m excited to share the v1 of Invio 🎉

Invio is invoicing software that is designed to do one thing and one thing only - make invoices. I made Invio because I wanted to make some invoices but all the open source selfhosted solutions I could personnaly find where too heavy for my use case, so I made my own.

Why Invio might be for you:

You dislike the feature bloat of alternatives
You want to get your invoices out there quickly
You prefer a modern tech stack

And here is why Invio might NOT be for you:

You need more advanced features like CRM, project management
You have many employees

Here are the biggest chances since the last post I made:

Switched to puppeteer for PDF rendering instead of wkhtmltopdf
Proper tax handling
XML exports
XML embedding in PDF
Darkmode
Custom invoice numbering patterns
Improved custom templates

About the AI usage, I want to clarify this better then last time. AI was used during the development of this application, mostly to speed up the development proces, the app is however not vibe coded. Features are planned intentionally by me, code is sufficiently optimized (as far as I am concerned). I am open to have a discussion about ai usage in coding.

What's an open-source tool you discovered and now can't live without?

Hey everyone, what’s one open-source tool you stumbled on that ended up being way more useful than you expected?

Could be for coding, AI/ML, writing, research, replacing Google, whatever helped you out big time but you don't hear people talk about much.

I use almost daily: Tuta Mail & Calendar, Signal, OpenSteetMap, Inkscape, but I feel like there are so many hidden gems that deserve more love.

Would be awesome to hear your picks, maybe even find some new favorites myself.

Project RogueGrid9 - Open-source P2P collaborative computing platform (Rust + React)

Hey r/opensource! 👋

I just launched the first public beta of RogueGrid9, a peer-to-peer collaborative computing platform I've been working on.

# What is it?

RogueGrid9 lets you share running processes (dev servers, apps, games) directly with your team using P2P connections - no cloud infrastructure needed.

Think of it like Discord meets VPS, but everything runs on your own hardware with peer-to-peer networking.

# Key Features

P2P Process Sharing \- Share terminals and running apps with teammates
Real-time Collaboration \- Text chat (voice coming in v0.2.0)
OAuth Authentication \- Google and GitHub login
Cross-platform \- Windows, Linux, macOS
100% Open Source \- MIT licensed

# Tech Stack

Backend: Rust + Tauri 2.0
Frontend: React 19 + TypeScript + Vite
Networking: Custom P2P protocol over WebRTC/WebSockets
Desktop: Native apps for all platforms

# Use Cases

Dev teams sharing local dev servers (no more ngrok bills!)
Pair programming with shared terminals
Gaming groups hosting game servers
Remote IT support
Collaborative debugging
Other cool stuff I havn't thought of

# Current Status (v0.1.5 Beta)

What works well: ✅ Windows and Linux fully supported ✅ P2P connections with NAT traversal ✅ OAuth authentication ✅ Text chat and grid management ✅ Process sharing and terminal emulation

What's experimental: 🚧 Voice chat (early stage) ⚠️ macOS process discovery (limited)

Not suported yet Turn relay servers for enterprise NAT has not been implemented yet due to bandwidth considerations but I plan to add this relitivly soon

GitHub: https://github.com/roguegrid9/roguegrid-desktop
Download: [https://github.com/roguegrid9/roguegrid-desktop/releases/latest](https://github.com/roguegrid9/roguegrid-desktop/releases/latest)
Website: https://roguegrid9.com

# Try It Out!

It's an early beta, so expect some rough edges. But it's fully functional and ready to use. I'd love to hear your feedback, bug reports, and feature ideas!

Windows and Linux work great. macOS users - you can use auth/chat but process sharing is limited (working on it for v0.2.0).

Thanks for checking it out! Happy to answer any questions. 🚀

Why Imposter Syndrome Continues to Exist in Open Source?

Most open-source developers say they have felt not good enough, typically because they've faced brutal public criticism and the visibility of their efforts. How can people best normalize errors and frame learning as a valued aspect of open-source culture? Are there communities or practices that are successfully providing peer support and acknowledging incremental progress?

Valkey Insight, a fast and open source GUI for Valkey

Hello everyone! A few months ago I switched from Redis to Valkey, but I continued using Redis Insight as my GUI tool. Thing is, I started encountering some missing features, especially when it comes to new Valkey features like Bloom filters.

There is basically no support in Redis Insight to explore these data types. A quick check on the feature requests also showed me that the developers have no plans to support it in the near future. Since I wanted an open source GUI tool for Valkey and I couldn't find anything that satisfied my needs, I just made my own in Rust.

https://github.com/ben-oswald/valkey_insight

The app is now in a very early but already more or less usable state (it still has a lot of bugs, stability issues, missing features and a simple placeholder desktop icon...). However, Bloom filters are supported! :)

Even though the support is currently very basic and needs to be extended, I plan on pushing out frequent updates to gradually complete the application.

I would love to hear your feedback! What features do you think are missing, and what design changes should I make?

Best Custom ROM especially for Tablets?

Currently I am on a journey to degoogle my tech, generally moving to more FOSS. Since having Linux on my PC works well for me, I am now thinking about replacing Android. I own Samsung Galaxy Tab S7 FE, running on Android 14. Doing research I found LineageOS and /e/OS as possible Custom ROMs, but before jumping in, I wanted to know, if someone happens to know more or even has experience regarding this topic? It seems very niche to me, but nonetheless I want go give it a try.

Are There Open Source Marketplace Builders That Support Self-Hosting?

I am looking for open-source marketplace-building platforms that support self-hosting. I want a solution where I can fully control the server, customise the code, and add or modify features based on my business needs. Are there any reliable open-source self-hosted marketplace builders available, such as Sharetribe, Spree Commerce, Bagisto, Cocorico, or OpenCart Multi-Vendor, that provide flexibility for customisation, including multi-vendor support, payment gateways, and custom workflows?

Why is opne source software always so ugly?

Hello everyone, I use a few open source projects but don’t contribute to many. However, I always check out the teams working on them (maintainers). One thing I’ve noticed about open source software is that it often looks unattractive—why is it always like this?

This issue of course has so many reasons to exisst;

1. Design tools barely have branching (Figma prices this out)
2. Open source software never has a design direction but has a functionality direction (functionality first)
3. The initial team never has a designer (this would help alot especially releasing guidelines for present and future use in terms of onboarding new designers to the team
4. How to "maintain" design contributions (in code i can review a PR) in design its a longer process
5. No clear way to attribute deisgn contributions; Devs can contribute ti a project and it appears on thier github with design this is not possible (unless your name is added to a list of contributors)
6. Which type of designers do open source projects want? Junior, Senior, mid? and how do you know?

been watching this video and it proves this; https://youtu.be/QYM3TWf\_G38?si=1EDyumRjGkxfVGNZ

Recently open-sourced a tool I built for my personal pain point, tips for maintaining?

Hey everyone, I recently open sourced a tool that I've built for devs using multiple github accounts to sync their work. I called it shōmei. Also I recently got my first contributor (yay)

It’s my first time sharing something with the community, so I’m pretty excited (and honestly a bit nervous lol).

Id really appreciate any feedback you might have, especially around:
\- Code: structure and readability
\- Docs: are they clear enough? I set up a small github pages website as well.
\- General best practices for open source projects?

I checked out some really big open source projects, but I'd really appreciate any tips from people with hands on experience.

I’m still learning as I go, so any advice or stories from your own first releases would mean a lot.
thanks for taking the time to check it out! :)

Would love your feedback on Argus v2

Hey everyone,

I’ve been working on Argus for the past year — a modular OSINT & recon toolkit designed for serious information gathering.
The new v2 just dropped, and it now includes 130+ modules covering domains, APIs, SSL, DNS, and threat intelligence — all accessible from a single command-line interface.

It’s open-source, fast, and built to simplify large-scale recon workflows.
Would love to hear your feedback, suggestions, or ideas for what to add next.

I’m 14 and I just published my first mobile app :D

hey people!

i’m Daamin and i’m a 14 year old from India. I just published my first app to the google play store. 

It’s called Anydle and it’s a Wordle clone with categories. In addition to the standard mode, you can choose from four presets : Tech, Science and Sports. When you pick a category, all possible answers relate only to that theme, making a new fun game mode. Instead of the daily word format, Anydle has an infinite word game mode. I made it using react native, expo and firebase.

check out the code here: https://github.com/Daamin909/anydle (Leave a star!)
you can download it here: https://play.google.com/store/apps/details?id=com.daamin.anydle 

I managed to publish it using my dad’s legal name because i’m below 18 😭
feel free to report bugs, or request features on the repo, or my email: ashai.daamin@gmail.com
