Antigravity vs Aider: what developers actually say
Based on 335 opinions on Hacker News from developers who discussed these two, most of them first-hand users.
Aider has the higher approval rate (60% vs 45%) and wins the only explicit head-to-head, but that rests on 34 opinions against Antigravity's 301. Antigravity draws heavy negative counts on reliability (57 vs 16 positive), usage limits (31 vs 18) and UX (29 vs 11), and its strongest aspect is speed (19 vs 7). Antigravity's cost mentions are close to even at 17 positive and 20 negative. Aider's small sample is clean on code quality (5 vs 1) and large codebases (3 vs 1), so it is the better pick for big repos and hand control, while Antigravity suits people who want an IDE and fast responses.
