Pi vs Windsurf: what developers actually say
Based on 459 opinions on Hacker News from developers who discussed these two, most of them first-hand users.
Pi comes out ahead on both evidence and sentiment: 423 opinions from 335 authors at 84% approval, against 36 opinions from 35 authors at 58% for Windsurf. Pi's customization aspect draws 150 positive mentions against 4 negative, and users name it over Claude Code 54 times. Windsurf's sample is thin, and its reliability aspect is 0 positive to 3 negative, with repeated complaints about quotas and pricing changes. Windsurf is the better pick only if you want a full IDE with cheap tab completion, and the data here supports that case weakly.
