GLM Coding Rush

A Chrome extension I use myself, and also a nice little example of “let the browser do the boring part”: it keeps an eye out for a restock, and the instant something’s back it clicks in fast, adds it to the cart, then stops at the payment page so you pay yourself (it never auto-pays). A handy reference if you want similar browser automation.

Highlights

• Checks for a restock on a schedule
• Reacts in well under a second the moment it’s back
• Adds to cart automatically, then stops at checkout for you
• Pauses and waits for you when a captcha shows up
• Runs entirely in the browser, no server
