Gemini CLI vs Kilo Code: what developers actually say
Based on 242 opinions on Hacker News from developers who discussed these two, most of them first-hand users.
Kilo Code comes out ahead on approval (63 vs 29) and on cost, with 4 positive and 1 negative cost mentions against Gemini CLI's 7 and 11. That lead rests on 31 opinions from 21 authors and no 90-day figure, so it is a weak signal. Gemini CLI has much more evidence (211 opinions, 163 firsthand) but a clear reliability problem: 55 negative mentions against 7 positive, and 29 negative against 7 in 2026-09. The one direct comparison went to Kilo Code, so pick Gemini CLI mainly for its terminal workflow and larger track record.
