ProofShot is just a CLI, not tied to any IDE. If you’re in Antigravity or VSCode and their built-in preview works for you, great. This is for people using Claude Code, Codex, or any terminal-based agent where there’s no IDE doing it for you. The main thing is really the PR artifact workflow - the agent records proof, you review it async on the PR.
Also it's headless. No idea if VSCode and antigravity are, guessing it's not 1:1 the same, though.
