Why isn't it more common to create cross-platform and portable applications / software using web technologies like JS, HTML and CSS ?

I try to get rid of my reliance on proprietary ~~(Microsoft)~~ software with open source projects as much as I can. And regardless of the type of open-source software I'm looking for, I realized I have the following criteria that often come up :

OS compatibility : with Windows, Linux and MacOS
Device compatibility : with PC, smartphone and tablet
Out-of-the-box : No installation required, must be ready for use as is
Portability : can be used from a USB
No telemetry and no requirement to be connected to the internet
Self-contained dependencies to avoid complicated set-ups
Noob-friendly to download, execute and use by a tech-illiterate grandma

Optional criteria :

Syncing available across devices
Easy to change its source code to customize the software / web-app

I realize that pretty much all of these requirements are fulfilled with what would essentially be portable web-apps.

TiddlyWiki is one such example, it's a portable notebook that fits in one single HTML file (but I don't intend to do an implementation that extreme) and it works as intended.

Keep in mind that the alternatives for the type of software I'm looking for are not resource-intensive apps and are often light-weight :

Notes-taking markdown app (like Obsidian) / or text editor
E-book and manga reader that supports different file formats (PDF, EPUB, CBZ, etc.) and annotation
Very simple raster graphics editor like Paint
File converters
Meme maker

All of this being said, it circles back to my initial question :

Why isn't it more commonplace to use basic web technologies to create open-source projects for light-weight applications ? They seem to offer so much apparent advantages in addition to the fact that every OS and every device has a browser where these "apps" can run seamlessly.

So what gives?

EzAntiAntiCheat (Repost)

EzAntiAntiCheat

Hi everyone,

I’m working on EzAntiAntiCheat, an open-source project designed for research and experimentation with kernel-level anti-cheat systems. Its purpose is to provide a safe framework for studying and managing situations where aggressive anti-cheat software interferes with each other, such as conflicts between Riot Vanguard and other anti-cheat platforms.

The project is fully open-source on GitHub: https://github.com/PalorderSoftWorksOfficial/EzAntiAntiCheat

I’m looking for contributors interested in: • Kernel driver development • System-level security research • Safe experimentation with software conflicts and aggressive protection mechanisms • Documentation, testing, and tooling improvements

Notes: • This project is intended purely for research and educational purposes. • It is not designed to bypass or disable anti-cheat systems for gameplay. • Improper use may render software unusable; please use responsibly.

Contributions, feedback, and collaboration are very welcome! If this post violates community rules please contact me instead of instantly banning me from the subreddit so i can fix the post from the issue! Extra Note: EzAntiAntiCheat completely wipes the anti cheat driver and if its gone the game might reinstall or crash as an fail safe.
Please private message me on reddit to contribute.

I built an ultra-fast, open-source Go web service for generating PDFs from HTML/JSON templates.

I'm excited to share a project I've been working on: GoPdfSuit, a high-performance Go web service designed for creating PDF documents from HTML and JSON templates. It's built on Go 1.23+ and the Gin framework, and it's completely open source under the MIT license.

I created this because I was tired of slow, clunky, and expensive commercial PDF solutions. GoPdfSuit is designed to be a fast, simple, and flexible microservice that you can drop into any project.

Key Features:

Ultra-Fast Performance: It can generate PDFs with sub-millisecond to low-millisecond response times, making it incredibly efficient for high-load applications.
Template-Driven: It uses a JSON-driven template system, which means you can generate complex, data-rich PDFs without writing any code. It also has a built-in web interface for real-time preview and editing.
HTML to PDF/Image Conversion: Easily convert entire web pages or HTML snippets into PDFs or images.
Interactive Forms: Supports AcroForm and XFDF data for filling out interactive forms.
Easy Deployment: It's deployed as a single binary, making it simple to get up and running.
Language Agnostic: Since it uses a REST API, you can use it with any programming language.

GoPdfSuit is a more flexible and cost-effective alternative to many existing solutions. If you work with PDFs, I'd love for you to check it out and let me know what you think!

/dev/push - Open source alternative to Vercel / Render

I wanted to deploy Python apps but still wanted to have a polished UX experience, like Vercel has.

So I built /dev/push for myself, and then decided to open source it.

You can host it on a Hetzner server (or any Debian/Ubuntu box) by running a single command:

curl -fsSL https://raw.githubusercontent.com/hunvreus/devpush/main/noscripts/prod/install.sh | sudo bash

It's pretty similar to Vercel or Laravel Cloud:

Git-based deployments,
Environment management,
Real-time monitoring,
Team collaboration,
Custom domains,
...

For now it's mostly Python and Node.js (in beta), but I'm working on adding other languages (PHP, Go, Ruby).

Many other things in the works: persistent storage, SQLite databases, scaling/resources settings, custom containers, remote nodes, etc.

It's a beta, but it's fully functional. Feedback and contributions are very welcome.

I’ve open-sourced an interactive simulator for UX testing (MVP). Built with React/TS/Vite, plugin-based, JSON-driven. Would love thoughts from the open-source community!

Hey folks,

I’ve been working on a project called SCOPE (Simulation for Cognitive Observation of Perception & Experience) and just made the MVP open source.

🔹 What it is:
An interactive, plugin-based simulator for exploring how people perceive and interact with interfaces.

JSON-driven questions (easy to add your own)
Abstract diagram style to isolate perception & intuition
Built with React + TypeScript + Vite
Extensible plugin system for custom test diagrams

🔹 Why:
I wanted a way to empirically test user intuition and perception that moved beyond theory and into hands-on experiments. The goal is to make it useful for UX researchers, designers, and anyone curious about human-computer interaction.

🔹 MVP status (v0.1.0):

Choose duration & difficulty
Several sample questions/diagrams
Early docs: setup, contribution guide, mockups, roadmap
Roadmap includes results dashboard + AI-powered summaries

🔹 Repo [GitHub\]:
👉 scopecreepsoap/scope-simulator: Simulation for Cognitive Observation of Perception & Experience (SCOPE)

I’d love any feedback — whether you think this could be useful in research, teaching, or just experimenting with UX design. And if anyone wants to contribute plugins/questions, the architecture is built for that.

Thanks!

I built RemoveMD.com – a simple tool to clean up your files before them posting on social media.

I'm working on a small side project called RemoveMD -- a privacy website that lets you remove private data leaks from your files. This idea is not very original, but I wanted to create something open source, easy to use and modern. So, there is a version that can be hosted locally (available on github), without any limitations and of course free. And another that I host that offers several paid plans for people who do not have the skills to use the local version. I noticed that this type of site often has a lot of ads. On RemoveMD there are no ads, and registrations are completely anonymous with an anonymous hash (You can create as many accounts as you want) and of course without email required.

I'm posting this message today to gather opinions, or ideas to add.

Thanks for reading (:

Calling all FOSS Developers! Help needed for improve newcomers's contributions

As a Open Source Contributor / Developer, which tools YOU think it would be great to have?

I'm on my last semester on computer engineering, and my final project is creating a tool that helps FOSS community newcomers (or simply on a specific repository) on how to contribute on that project. The tool will be released as a VSCode extension.

I was thinking on showing one graph of all the features and their relationships, and another one showing the flow of execution...? Something very similar to this awesome tool (shout-out for Ahmed Khaleel), but on different perspectives being showed inside VSCode. In other words, not necessarily the extension will do everything for you, but it can help you on to analyse and understand that project better. Thas the main idea.

Thing is: i ain't no expert on OSS contributions and it's workflow. If i really want to develop my project, so i think i need to understand better what OSS developers would like to have on their daily activities. And that's why i'm here! :)

Any help would be appreciated!

I built GoferBroke an anti entropy gossip engine in Go

I'm excited to announce my first ever release of an open source project GoferBroke

GoferBroke is an anti-entropy gossip engine built on a custom TCP protocol built with Go. The goal is to make it easy to embed gossip directly into your applications, so each instance can join a cluster, share state, and detect failures in a decentralized way.

I also built a gossip-toy example you can run to spin up multiple app instances and actually watch them gossip, sync state, and handle failures.

I know the project isn't perfect and i'm sure there are many things that could do with changing or optimising but despite that, I wanted to share the project with the community as I always liked seeing posts about new releases of cool and interesting projects (not saying my project is cool or interesting but you get the point).

I originally announced this in r/golang as the project is built entirely in go but as it's open source I wanted to post it here as well to contribute to the open source community.

I hope you find something here that’s interesting or useful to your own work. And please keep sharing your projects too. I love reading about them and always find them inspiring.

I build Quickmark - a Markdown linter with first-class LSP support

I got annoyed enough with Markdown tooling that I decided to build my own.

Here’s the problem: markdownlint and similar tools do the job, but they’re not exactly fast, and worse - they don’t integrate cleanly into editors because they don’t speak LSP. That means you either run them as one-off CLI tools or settle for half-baked editor plugins.

So I created Quickmark, a Markdown linter written in Rust. It’s:

* Fast
* Built on the Language Server Protocol, so it plugs into any editor that supports LSP: VSCode, Neovim, JetBrains, etc. – Available as both a CLI tool and an editor integration

I’m sure there are bugs hiding, and I’d love for other people to try it and break it. Feedback/issues/PRs all welcome.

Looking for Smartwatch with SIM/eSIM (LTE) and GPS with sensor data acces

Hello

I'm looking for smartwatch/band options that have LTE (no phone required to be paired), on which I can install my own app, or that provides APIs via a cloud service, to be able to fetch location (GPS) and other sensors data (battery, accelerometer, etc).

Requirements:

* Must work standalone (no smartphone nearby, except maybe for the initial setup)
* Needs **SIM/eSIM** for connectivity and **GPS** for location.
* I need to access **location and battery level automatically**, ideally via API (either the manufacturer’s cloud API or my own app running on the device).

Optionally, it should be able to send SMSs with the data, in cases of bad coverage.

What I've found are closed-source without API, or using WearOS (samsung, xiaomi, garmin) but quite expensive for my needs. Also looked into kids smartwatches but these are very closed-systems and not very reliable anyway, with terrible battery life.

Any help is appreaciated. Thank you

AMA: We’re an open source company from Germany employing 21 people: Ask us anything!

We’re putting up this post a bit ahead of time, so you can think of questions and post from whichever time zone you’re in.

We’ll start answering from 3PM CEST until we either run out of questions or we go home for the night - but you can keep posting more questions if you want, we’ll check in in the coming days as well!

A big Dankeschön to the mods for their amazing cooperation in setting all of this up together!

Hello fellow open-source enthusiasts!

A little bit about us:

We at Icinga are a team of 21 people working together on our flagships Icinga and Icinga Web, its modules and extensions, and a bunch of other projects in the open source monitoring world. You can find pretty much all we do over on our GitHub.

Icinga started out as an open source project, as a fork of Nagios, back in 2009. Since then, it’s been completely rewritten and grown into its own monitoring platform, shaped by contributions from people all over the world. Community and openness have always been at the heart of it, and that’s something we’re making sure to keep.

Our goal is straightforward: build a strong open source monitoring tool and keep improving it, so you can monitor your entire infrastructure with confidence. That means keeping up with new requirements and pushing new ideas forward.

We’ve been part of the monitoring community for many years, and we work with companies of all sizes to better understand the real-world challenges of running large and diverse environments.

In 2018 we set up Icinga GmbH to make sure there’s stable funding and proper product management behind the project. These days we’ve got a partner network, and we provide services, support and training for folks who need it. Our home base is Nuremberg, Germany, where we still see each other regularly in our offices.

\---------------------------------------------------------

Feel free to ask us anything: technical, business related, community related, fun, or completely random. We’re happy to talk monitoring, open source, company life, or whatever else comes to mind.

You can also upvote the questions you want to see answered first!

We’ll be using our shared u/icinga and note who is answering with a /Name to protect everyone's privacy / activity on here :)

Why does Firefox no longer offer an APK file on its website?

After getting sick with all the tacking data Google had on me (https://myaccount.google.com), I took my phone completely off-grid. Installed LineageOS. Setup service with Ooma, and ported my old number there. Removed my SIM. Installed Session for texting. And now I'm trying to install a modern web browser, but none of them offer apks on their sites anymore.

Is there a reason for this?
