GitHub Copilot vs Google Antigravity

GitHub Copilot edges out Google Antigravity by 0.3 points (8.3 vs 8.0) -- a A-tier vs A-tier split that's narrow but real. Not a blowout; both belong on a shortlist. The score gap shows up most clearly in the categories that matter for GitHub Copilot's strengths, so if those categories are your priority, the lead translates.

Pricing-wise, both tools have a free tier (GitHub Copilot starts $0, Google Antigravity starts $0), so you can test either without committing. Compare what each free tier actually unlocks -- usage caps, model access, and feature gates differ a lot more than the headline price suggests, especially as both vendors have tightened limits in 2026.

By use case: pick GitHub Copilot when existing copilot subscribers on business/enterprise or grandfathered pro/pro+ seats. Pick Google Antigravity when developers working on large, multi-file projects who want to parallelize their workflow. The two tools aren't fighting for the same person -- they're aiming at adjacent jobs that occasionally overlap. If you're squarely in GitHub Copilot's lane, the tier-list ranking and the use-case fit point the same direction; if you're in Google Antigravity's lane, the score gap matters less than the fit.

Bottom line: GitHub Copilot is the safer default for most readers, but Google Antigravity is competitive enough that the tie-breaker is your specific workload, not the spec sheet.
