Antigravity
Google's agent-first coding environment, where you hand the AI a task and review the work rather than typing every line.
Antigravity is Google’s development platform built around agents rather than autocomplete. Instead of suggesting the next line while you type, it takes a described task, plans it, writes across multiple files, controls a browser to check its own work, and comes back with results and screenshots. You steer it by leaving comments on what it produced, the way you would comment on a shared document.
It runs Google’s own Gemini models and also supports models from other labs, and it is free for individuals in preview. It matters mostly as a signal: the big vendors now assume the unit of work is a task you delegate, not a line you complete.
