6 THINGS WORTH SEEING TODAY

Today's picks mostly connect one thing to another: a design canvas where a coding agent draws what it built, a Mac app that forwards WeChat chats to AI and notes in one step, and a tray app that casts a Linux laptop to the TV. Add an open-source builder that makes a website from a description, an open-source ERP for manufacturers covering orders through production and quality, and a Linux sandbox that isolates agents and unfamiliar programs without leaving your usual setup. Many candidates were one brand promoting itself or repositories just posted, so only six made the cut. Licences and limits are stated as they are.
