Best app stack of 2026, according to LLMs: Next.js, Supabase, Vercel, Stripe (openllmrank.io)

In a recent analysis, five AI language models—ChatGPT, Claude, Gemini, Perplexity, and Grok—were asked about the best tech stack for building apps in 2026. The consensus points to a default stack consisting of Next.js, Supabase, Vercel, and Stripe, which was recommended together in 68% of the responses. This stack's significance lies in its strong cross-engine agreement, highlighting its robustness for future app development, while also indicating a potential shift in how developers approach tech choices by leveraging AI insights. Despite their consensus on the core stack, the models showcased variability in recommending additional tools and services, particularly in areas like analytics and error monitoring, where no singular offering dominated. Notably, the engines did not favor their own frameworks or models, with most endorsing competitors instead. This suggests that the AI community is evolving towards a more collaborative landscape, where the focus is on the best tools rather than brand loyalty. As developers increasingly rely on AI for stack recommendations, integration with these leading products may dictate success in the app development landscape of the coming years.
