Frequently asked questions
Can SprintBuild really ai internal tool builder from a single prompt?+
Yes. SprintBuild runs every session in a real Vercel Sandbox, so the agent can install dependencies, run scripts, and start a dev server like it would on any production box. The first prompt scaffolds the project; follow-up prompts iterate on it.
What stack does the agent use to ai internal tool builder?+
Default stack: Next.js 16, Tailwind CSS v4, Supabase, Vercel Sandbox. The agent can swap any layer if your prompt asks for it — different ORM, different host, different auth provider.
How long does it take to ship?+
For a typical ai internal tool builder prompt, you’ll see a running app within a few minutes and a polished version after 2–3 prompt iterations. Heavy customisations and integrations take longer; the credit system charges per agent turn so you only pay for the actual work.
Can I export the code?+
Yes. SprintBuild keeps the full source visible in the file explorer during every session. You can browse, copy, and download files; native GitHub push is on the roadmap.
