JetBrains Junie vs Aider: what developers actually say

Neither tool wins a direct comparison: no commenter picked one over the other, and both land at 60% approval. A rests on more evidence, 53 opinions from 34 authors against 34 from 39, with its clearest edge in code quality at 8 positive and 1 negative. A's recent record is weaker at 33% approval over 90 days, and its complaints cluster around reliability, slow or crashing runs, and tight quotas. B is the better pick for cost and control, with one user building a working Chrome extension for about $28 in API credits and praise for local data handling, but its UX signal is negative at 1 positive and 3 negative, and six users left it for Claude Code.
