Based on 1,081 opinions on Hacker News from developers who discussed these two, most of them first-hand users.
OpenCode comes out ahead overall. It has higher approval (66 vs 45) on more opinions (780 vs 301), and its cost sentiment is strongly positive at 113 positive vs 24 negative, while Antigravity sits at 17 vs 20. Antigravity's weak spot is reliability, with 57 negative mentions against 16 positive, and its UX runs 11 positive vs 29 negative; OpenCode's own reliability is also its worst aspect at 39 positive vs 83 negative.
