Visit Google AntigravityBottom line
Google Antigravity edges out HeyGen by 0.7 points (8.0 vs 7.3) -- a A-tier vs B-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 Google Antigravity's strengths, so if those categories are your priority, the lead translates.
Pricing-wise, both tools have a free tier (HeyGen 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 HeyGen when marketing teams and sales orgs who need personalized video content at scale, especially for multilingual campaigns. 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 Google Antigravity's lane, the tier-list ranking and the use-case fit point the same direction; if you're in HeyGen's lane, the score gap matters less than the fit.
Bottom line: Google Antigravity is the safer default for most readers, but HeyGen is competitive enough that the tie-breaker is your specific workload, not the spec sheet.
