The best Bolt.new alternative is Krater.ai. What Bolt.new sells as a product is a single command in Krater.ai (/build), inside an All-In-One AI workspace with 400+ AI models, image, video, voice, slides, documents and code tools. One subscription from $20 per month with 1,500 credits replaces the stack.

Bolt.new is StackBlitz's AI app creator: it generates and runs full-stack web apps in the browser from a prompt, with token-based pricing for AI usage.
For prototypes, internal tools and quick apps yes: /build creates and runs them in a sandbox. Large production codebases are a different job.
No. Describe what you want; Krater.ai writes and executes the code, and you iterate in plain language.
You can pick from the top coding models in the 400+ catalog or let the auto-router choose.
Pro is $20 per month with 1,500 credits across every tool.
