12 tools. one app. fully offline. built solo in one month.
everything a web developer or SEO specialist needs; without switching between 12 different tabs, services, or subscriptions.
if you've ever finished building a website and then spent hours on SEO setup, meta tags, schema generation, image optimization, broken link checks, accessibility scans;you know how much time that eats.
aether does all of it in one place. injection into your HTML. batch operations across hundreds of files. no cloud. no subscription. no data leaving your machine.
built by a full-time web developer who got tired of the same painful post-launch workflow.
two real features. not just a readme update.
the standard way to load videos on a page is to load all of them at once. this is a bad idea when you have more than two or three;your page slows down, RAM spikes, and users on mobile or limited data plans suffer.
aether's smart video lazy loader works differently. when a video is off-screen, it shows a low-resolution crystalline placeholder. when the user scrolls to it, aether starts downloading the video in 5 parallel chunks simultaneously;similar to how advanced download managers work;then assembles them seamlessly and displays the video as one piece. faster start, smoother playback, no wasted bandwidth on videos the user never reaches.
for users in countries where internet costs money per megabyte, this matters a lot.
| v2.0 | v2.2 | |
|---|---|---|
| load time (20 videos) | 4–6 seconds | ~1 second |
| RAM usage | 400–600MB | 80–120MB |
| videos loaded before scrolling | all of them | zero |
same philosophy for images. when a high-resolution image is off-screen, aether generates a tiny WebP preview;same dimensions, same format, but compressed down to roughly 2KB regardless of the original file size. that preview loads almost instantly and is displayed as a soft blur placeholder.
while the user sees the preview, the full-quality image downloads silently in the background. the moment it's ready, it replaces the placeholder seamlessly;no layout shift, no pop-in.
every original image, regardless of format, is automatically converted to lossless WebP during this process. smaller file, better quality, faster load. the compression is tuned automatically to find the best lossless result.
early stage, but functional. lowercases all comments across your codebase, removes the obvious AI-generated phrasing that makes code feel like it was written by a documentation bot. batch operation across files. the roadmap for this one goes much further;this is just the foundation.

download aether-launcher.bat and run it. that's it.
it will check your python version, clone the repo, set up a virtual environment, install dependencies, and launch aether;automatically. if something is missing it tells you exactly what and where to get it.
aether-launcher.bat
if Windows Defender flags it, click "more info" → "run anyway". it's a setup script, not malware;you can read every line of it before running.
download aether-launcher.sh, make it executable, and run it:
chmod +x aether-launcher.sh
./aether-launcher.shsame as the windows version;checks python, clones the repo, sets up the environment, launches aether.
git clone https://github.com/mh3nj/Aether.git
cd Aether
python -m venv .venv
# windows:
.venv\Scripts\activate
# mac/linux:
source .venv/bin/activate
pip install -r requirements.txt
python main.py- python 3.9+
- 4GB RAM (8GB recommended if you tend to have a lot open)
- internet only for PageSpeed Insights;everything else is fully offline

PySide6 # UI framework (Qt6)
BeautifulSoup4 # HTML parsing
Pillow # image processing
requests # PageSpeed Insights API calls
black # python code formatting (optional)
jsbeautifier # js/html/css formatting
pyspellchecker # spell checking (optional)
- windows defender may flag the .bat launcher;it's a setup script, every line is readable before you run it
- first launch takes ~30 seconds while pip installs dependencies;only happens once
- PageSpeed Insights requires internet;all other features work fully offline
- the .sh script opens nano to edit your .env on first run;if you don't have an API key yet, just close it and it'll continue
- the fontawesome icons dont load properly which i'll fix it in next versions <3

MIT. use it, fork it, ship it, build on it. just don't blame us if something breaks.
this project was built during a period of severe internet restrictions in iran.
no stack overflow. no access to npm documentation. no youtube tutorials. no reliable connection to the tools most developers take for granted. just whatever was cached locally, whatever could be reasoned through from first principles, and the determination to ship something real anyway.
55 hours of focused work. 18,000+ lines of code. 31 features. 12 tools. one month. one developer.
it works. it's useful. and it was built under conditions that would have stopped most projects before they started.
Aether;the breathing light of code.
