Antigravity vs Windsurf: what developers actually say
Based on 337 opinions on Hacker News from developers who discussed these two, most of them first-hand users.
Antigravity comes out ahead on the strength of its evidence: 301 opinions from 259 authors and 238 firsthand reports, against 36 and 31 for Windsurf, plus the only explicit head-to-head switch, which went from Windsurf to Antigravity. Windsurf has higher approval, 58 versus 45, but that rests on 36 opinions. Antigravity's weak points are concrete: reliability is 57 negative to 16 positive and usage limits are 31 negative to 18 positive, while speed (19 to 7) and code quality (15 to 8) lean positive. Choose Windsurf when a $20 plan with broad model access and favorable UX mentions (4 to 2) outweighs a thin track record.
When developers explicitly said they prefer one or switched: 1 picked Antigravity, 0 picked Windsurf.
