Yeah I've used it today quite heavily and I genuinely feel it's given me the best AI workflow yet, and I say this coming from Jetbrains + Claude Code.
Personally I felt having immediate access to the VSCode extension ecosystem to be a huge boon and I quickly got a setup to my liking.
Have you tried Cursor though? To me, that is the system to beat.
I haven't no. I could be wrong but I always saw Cursor as more of a low-code tool whereas Claude Code + IDE as the more professional combo.
AI integration into all aspects of the IDE is the killer feature of Cursor for me. Also access for $20 a month to every important model out there, and once you go over your credits, they grant you about another $25 in free credits and then you can work pretty much unlimited in Auto mode where it automatically picks the model for you.
Anthropic and OpenAI are investing a lot into this space and are now competing directly with companies like Cursor. Cursor's biggest moat at the moment is their tab completion model, which doesn't exist in the Anthropic's and OpenAI's current offerings and is leagues ahead of Github Copilot's.
Antigravity is a VSCode fork that adds both Google's own tab complete and an agent composer, similar to products like https://conductor.build/. Assuming that Google doesn't shoot themselves in the foot (which they seem to like doing), we'll see if wrappers like Cursor / Windsurf / Cognition can compete against the big labs. It's worth noting that the category seems to be blurring, since Cursor has trained not only their own tab complete model but also their own agent model.
