Pricing, sourced

Bolt offers a browser-based build environment, database tools, and deployment controls. Onspace has clearer app-builder positioning, cross-platform delivery, and App Store publishing. The better fit depends on the workflow you need and how much guidance you want before choosing a plan.

Quick verdict — Bolt suits infrastructure; Onspace suits mobile app reach

Bolt is the stronger fit when a browser IDE, database management, custom domains, and user authentication matter most. Its review score is 72/100: documentation and specific writing are strengths, while a roughly 5.3MB network payload and more than five seconds of JavaScript execution on mobile are important performance concerns.

Onspace is the stronger fit for freelancers, startups, and small businesses that want to create mobile or web apps without code and need cross-platform delivery, App Store publishing, Figma import, or a managed backend. Its review score is 75/100, supported by clear audience positioning. The tradeoffs are a 3.9-second mobile LCP, a 1.9MB hero image, and limited guidance in the pricing grid.

Choose by use case

Choose Bolt if your work benefits from a browser IDE and WebContainer sandbox, database management, one-click deployment with custom domains, or user management and authentication. Choose Onspace if App Store publishing, cross-platform deployment, Figma import, or a managed backend are central to the project.
