Bolt vs Krea: Which is better?

Bolt is an AI-powered full-stack web application builder by StackBlitz that generates, runs, and deploys complete apps directly in the browser from a single text prompt. Unlike other AI coding tools, Bolt executes real Node.js environments in WebAssembly, meaning there is nothing to install — just describe what you want to build and Bolt produces a working app with frontend, backend, and database wired together. It supports React, Next.js, Svelte, and dozens of other frameworks, making it the fastest path from idea to deployed web application.

Krea

Krea is an AI image and video creation suite combining real-time generation, upscaling, model training, and an infinite canvas for collaborative editing. Artists, marketers, and product teams use it to iterate on visuals 10x faster than with single-shot Midjourney prompts. Supports both Flux and Stable Diffusion model families.
