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.
Leonardo AI
Leonardo AI is a browser-based image generation platform that produces high-quality visuals using a range of fine-tuned models, including its own proprietary ones. It is used by game developers, illustrators, and content creators who need consistent characters, concept art, or marketing assets at scale. The platform offers more model control than most consumer tools, though the credit system can feel restrictive on the free tier.
