Instavideo is a front-end-only short-form video feed (HTML/CSS/JS). It uses localStorage for all personalization and does not require login, backend code, cookies, or uploads.

Go to Hosted Website for an instant video feed!

• index.html
• css/styles.css
• js/app.js
• videos/ (place your .mp4 files here, referenced as ./videos/<file>.mp4)
• tags.txt
• valid_tags.txt

Begin by opening a powershell window as administrator, then Enter:

irm https://tecona-yen.github.io/instavideo/install.ps1 | iex

New-NetFirewallRule -DisplayName "Web Server HTTP" -Direction Inbound -LocalPort 80 -Protocol TCP -Action Allow

or run these commands:

DISM /online /enable-feature /featureName:IIS-WebServerRole /All

Now download copy the files from instavideo-main to the C:\inetpub\wwwroot folder using If you don't have git cli installed, download the respority maually and copy all files and dictionaries to the wwwroot folder.

del /Q C:\inetpub\wwwroot
rmdir C:\inetpub\wwwroot
gh repo clone tecona-yen/instavideo C:\inetpub\wwwroot

Restart IIS and test to make sure the website is working

iisreset
start chrome 127.0.0.1:80 || start msedge 127.0.0.1:80

Optionally, you can enable port fowarding afterwards

Because the app fetches text files, use a static server, try this command:

python3 -m http.server 8000

Then open http://localhost:8000.

• valid_tags.txt: one allowed hashtag per line (must start with #).
• tags.txt: filename.mp4: #tag1, #tag2.
• A video appears in feed only if:
  • it is listed in tags.txt,
  • has at least one valid tag,
  • and metadata can be loaded in browser,
  • and duration is <= 1200 seconds.

State is stored as human-readable JSON under localStorage key instavideo_state.

It includes:

• tagModel (a, b, w per tag)
• controls (strength, exploration, overrideEnabled, override)
• recentVideos, recentTagCounts, and history

In the feed, use the ⚙️ button to open controls:

• Personalization Strength slider
• Randomness/Exploration slider
• Manual override toggle
• Tag search + per-tag override slider
• Reset Overrides
• Randomise Overrides
• Reset Learned Profile
• Reset History

• Issue when scrolling on desktop with mouse, or scrolling too quickly, multiple videos can play at once, leading to visual and sound glitches.
• No upload system yet
• The default, starting amount of videos is inherently limited to about 60, you will need to add far more content (thousands a least) to make a full functional app that people will want to spend time on!
