I made a small web-based 2D skeletal animation app from scratch in C

Hi everyone,
I’ve been working on a small 2D skeletal animation app written from scratch in C using raylib. It lets you build simple bone-based puppets, animate them frame-by-frame, preview the animation, and export it.

I used raylib for pretty much everything, and microui for the UI, along with a small custom window-compositing layer I built to handle the floating virtual windows.

Right now it doesn't support skin deformations nor frame interpolations, but that's on the queue, alongside many other features I’d love to add.

You can test the app yourself here: **https://puppetstudio.app**
And the repository is here: **https://github.com/SuckDuck/PuppetStudio**

Any contribution is welcome, especially example puppets, since I’m not much of an artist and would love to include better sample assets.
Any feedback would also be appreciated!

What apps that you wish were native to your OS not a electron based one

Title says it all. I want to know what apps you regularly use that are not native builds and are web technology wrapped in Electron.js.

Why am I asking this?

I see a trend that developers don't learn to build apps for the specific platform and in the end build bloated apps that take around 1 GB space in RAM even when Idle. So that is very annoying and I want to change that. I will try to quickly build those apps to help you out.

Lets discuss that

Criteria:
1- Should be open source
2- Don't have any third party dependency to paid api or anything like that

I made a simple Epic Games Launcher account switcher (Epic Switcher)

Hey everyone!

I wanted to share a little side project I've been cooking up: Epic Switcher, a completely free and open source tool I originally built for myself and a few friends.

It solved a small annoyance we kept running into, and since it ended up being way more useful than I expected, I thought others might vibe with it too.

If you're curious, here's the project's repo: https://github.com/symonxdd/epic-switcher/

If you check it out, I'd really appreciate any thoughts, ideas or issues you wanna drop my way. And if not, no worries at all. I'm just happy to put something back into a community that's taught me a ton 💛

Thanks for reading, and hope your day is treating you kindly ✨

help with freac:

Hi,
I have multiple MP3 files downloaded from YouTube that contain chapters. When converting in fre:ac, the chapters are causing the audio to split into multiple files. I need one single MP3 per download with chapters ignored.

Can someone please guide me on the correct fre:ac settings to disable chapter splitting and bulk convert the files properly?

Thank you.

Using ClickHouse for Real-Time L7 DDoS & Bot Traffic Analytics with Tempesta FW

Most open-source L7 DDoS mitigation and bot-protection approaches rely on challenges (e.g., CAPTCHA or JavaScript proof-of-work) or static rules based on the User-Agent, Referer, or client geolocation. These techniques are increasingly ineffective, as they are easily bypassed by modern open-source impersonation libraries and paid cloud proxy networks.

We explore a different approach: classifying HTTP client requests in near real time using ClickHouse as the primary analytics backend.

We collect access logs directly from [Tempesta FW](https://github.com/tempesta-tech/tempesta), a high-performance open-source hybrid of an HTTP reverse proxy and a firewall. Tempesta FW implements zero-copy per-CPU log shipping into ClickHouse, so the dataset growth rate is limited only by ClickHouse bulk ingestion performance - which is very high.

[WebShield](https://github.com/tempesta-tech/webshield/), a small open-source Python daemon:

* periodically executes analytic queries to detect spikes in traffic (requests or bytes per second), response delays, surges in HTTP error codes, and other anomalies;

* upon detecting a spike, classifies the clients and validates the current model;

* if the model is validated, automatically blocks malicious clients by IP, TLS fingerprints, or HTTP fingerprints.

To simplify and accelerate classification — whether automatic or manual — we introduced a new TLS fingerprinting method.

WebShield is a small and simple daemon, yet it is effective against multi-thousand-IP botnets.

The [full article](https://tempesta-tech.com/blog/defending-against-l7-ddos-and-web-bots-with-tempesta-fw/) with configuration examples, ClickHouse schemas, and queries.

Open Source Test Management - TestPlanIt

https://github.com/testplanit/testplanit

Just released - a full featured open source test management platform called TestPlanIt.

If you’re looking to self-host something that will scale and grow with you, please have a look!

If you want to try before installing there is a demo on the website. You can use the free trial on the website to set up an instance for your own private data if you need a better idea of how it works in the real world.

If you like it I can help you get it going on your own server. I promise I’m not a robot. Just a guy who didn’t like the current open source tools and frustrated with the increasing costs of the paid ones.

I built a lightweight headless CMS for Firebase (Open Source, Svelte 4)

Hey everyone,
I’d like to share a small open-source project I’ve been working on: Firelighter CMS (fl-cms) — a minimal, self-hosted CMS for Firebase/Firestore.

Why I built it

I needed a simple way to manage content (blog posts, release notes, documentation, small knowledge bases) directly in Firestore, without using a full-blown CMS or paying for a SaaS.

Tools like FireCMS are powerful, but for my smaller apps they felt a bit heavy. complex model configuration, modal-based editing, and no longer a free cloud version. I wanted something simpler and more focused on straightforward content editing.

So I built a lightweight alternative using Svelte 4.

What it does

- Connects to your Firebase project using only your config
- Stores its schema inside Firestore under a schema collection
- Lets you define content models in JSON
- Provides a dedicated editor (no popups, no inline editing)
- Content is structured in sections that can be reordered easily
- Uses Markdown via bytemd for writing
- Includes a lightweight media browser for Firebase Storage

MIT-licensed & fully client-side (self-hosting is trivial)


Tech stack

Svelte 4, TypeScript, CodeMirror, bytemd.

Why it might be useful

If you’re building small to medium Firebase apps and just need a simple content editor, not a large enterprise CMS, this might be a good fit.

I’ve started using it in a few of my own projects, and with subcollections it becomes easier to handle multi-language content as well.

Looking for feedback

I’d appreciate feedback, ideas, or contributions.

Looking for open-source CI / CD alternative to GitHub Actions.

Looking for open-source alternatives to GitHub actions with support for running on VMs (I want to avoid running privileged containers) and ephemeral runners. I'm aware that Forgejo is working on a solution for this. But was curious if any other solution exists.
I want to use external autoscaling solutions like GARM to scale runners and run jobs on individual ephemeral runners.

Whatever happened to "post-open source"?

A few years ago there was an idea by one OG open source pioneer to create a new set of source-avalible licenses that would allow commercial usage in exchange for 1% of revenue, and open-source developers could dual-license their code (e.g. "MIT OR Post-Open") and still get a share from that 1%.

"News" section on their website (postopen.org) is empty and evidence of the last update was a year ago, some links are dead. It this abandoned?

Call out for backend developers and interested techies

Hello folks, I am the founder of Qodex.ai we are a deep tech startup and an expert in Automated API testing and security.

I built an Open sourced tool called ApiMesh it scans your codebase and instantly generates OpenAPI 3.0 specs plus an interactive HTML docs page. No setup, no manual writing.

GitHub repo: https://github.com/qodex-ai/apimesh

It works across Python, Node.js, Go, Rails, Java and more. It picks up all your REST endpoints, params, auth and schemas straight from the code and outputs a clean swagger.json + a self-contained docs file you can open in any browser.

The goal is simple: help teams avoid missing, outdated or accidental endpoints by keeping docs always synced with the repo.

If you want to try it out or suggest improvements, we'd really appreciate the feedback. PRs are welcome.

Thank you!

A file-based Postman alternative

Hi all, I have been working on an open-source Postman alternative for a month and I have just finished the first set of key features:

# File-based API client

* Define workspaces, collections, and requests in JSON
* Works well with Git, code review, and keeping API examples next to your code

# Mock servers

* Define local HTTP/HTTPS endpoints in JSON
* Jest-style matchers in configs, like `any(String)`, `stringContaining('foo')`, etc.
* Request **forward** (acts like a proxy)

# Middlewares

For example `requestMiddleware` that gives you full control before/after a request. Useful for auth, logging, custom workflows, etc.

Next, I plan to add API testing automation features etc. It does not have much difference to other similar projects now, but it could be interesting soon.

Intro and docs are here: [https://hanlogy.github.io/api-studio/](https://hanlogy.github.io/api-studio/)

What do you think? :)
