What they are
Bolt.new
Bolt.new is a browser-based AI app builder by StackBlitz that generates, runs, and deploys full-stack web applications from a plain-text prompt, with no local setup required. It uses WebContainers to execute code live in the browser, supports multiple JavaScript frameworks, and integrates with Supabase, GitHub, Figma, Netlify, and Stripe. Pricing runs on a token consumption model, where larger and more complex projects burn through allocations faster than simple prototypes. The free tier is genuinely usable for experiments, but the daily token cap makes it impractical for sustained development work.
Flux
Flux is a family of text-to-image models from Black Forest Labs, the team behind Stable Diffusion. It generates high-resolution, photorealistic and stylized images from text prompts, with strong prompt adherence and fine detail. Creators, designers, and developers use it via API or third-party platforms. Flux produces genuinely impressive output, but there is no native consumer app, so getting started requires some technical setup or a compatible host.
