Capacity vs ShipFast
Choose Capacity if you want prompt-to-app building and faster prototypes without owning a boilerplate codebase; choose ShipFast if you want a proven Next.js starter you can edit and ship as conventional SaaS code.
Capacity and ShipFast both help founders launch faster, but they sit on opposite sides of the build-stack decision. Capacity is an AI app builder that turns prompts into full-stack web apps with deploy-oriented workflows. ShipFast is a battle-tested Next.js SaaS boilerplate — auth, payments, SEO scaffolding — that you clone and customize as real code.
