OpenCode vs Aider: what developers actually say
Based on 814 opinions on Hacker News from developers who discussed these two, most of them first-hand users.
OpenCode comes out ahead on volume and on cost, customization, and usage limits: 780 opinions from 569 authors versus 34 opinions for Aider, and 113 positive against 24 negative cost comments. Its weak point is reliability, with 83 negative against 39 positive, and approval fell from 85 in November 2025 to 49 in October 2026, with 55 over the last 90 days against 66 overall. Explicit preferences run 3-0 for OpenCode, though each tool appears 3 times in the other's preferred-instead list, so the head-to-head signal is thin. Aider is the better pick only for a narrow case: its small sample shows positive code-quality and large-codebase notes (5 to 1 and 3 to 1) and praise for respecting .gitignore and keeping data local.
When developers explicitly said they prefer one or switched: 3 picked OpenCode, 0 picked Aider.
