OpenCode comes out ahead on evidence volume and on cost and customization scores. It has 780 opinions from 569 authors, 597 of them firsthand, against 38 opinions and 26 firsthand for Kiro, with approval at 66 versus 59. Its cost/pricing split is 113 positive to 24 negative and customization is 83 to 8; reliability is the weak spot at 39 positive to 83 negative. Kiro's sample is too thin to rank with confidence, so it is the better pick only for spec-driven IDE work, especially inside an AWS shop.

Choose OpenCode if

  • Want a terminal agent with a large, measurable user base
  • Care about cheap plans and deep customization
  • Can accept weaker reliability scores for a broad plugin ecosystem

Choose Kiro if

  • Want spec-driven work inside an IDE
  • Work in an AWS shop and want both CLI and IDE
  • Are willing to trial it on thin Hacker News evidence
