osschat rebrand and new 8-bit logo

This update refreshes the product identity across the web app and extension. It also improves how osschat looks when saved to your home screen or shared on social platforms.

New osschat branding

The app name has been updated from OpenChat to osschat across key screens, including the home page and sign-in experience. This makes the product name consistent wherever you see it in the UI.

Page metadata was also updated to match the new branding, including the title and description. Social sharing now uses dedicated Open Graph and Twitter tags so link previews show osschat details and the correct image.

Updated logo and icons

A new 8-bit triangle logo (teal on charcoal) is now used across the web app and related assets. This helps keep the visual identity consistent across tabs, bookmarks, and installable app surfaces.

• New osschat logo assets for the web app, including logo.svg and PNG variants
• Added an iOS home screen icon via apple-touch-icon.png and an apple-touch-icon link tag
• Updated PWA manifest app name, plus theme and background colors
• Refreshed extension icons across multiple sizes (16 to 128px)
