About
We build software by describing it.
Sprint from idea to running app, powered by AI and a real sandbox. SprintBuild is the end-to-end version of that promise: an agent, a real sandbox, a live preview, and the file tree always visible while it works.

What we believe
Run code, don’t just generate it.
Every SprintBuild session boots a real Vercel Sandbox. The agent installs dependencies, runs scripts, and starts a dev server — so what you preview is what would actually ship, not a hallucinated output.
Pick the right model for the job.
Claude Opus, Claude Sonnet, GPT Codex, and Grok Reasoning are all wired through the Vercel AI Gateway. Switch models per turn; pay for what you use.
Treat errors as input, not failure.
Build failures and runtime errors stream back to the agent. The auto-fix loop closes most regressions in one or two turns without human escalation.
Keep the source visible.
No black box. The file explorer is always live and every command the agent runs streams its stdout and stderr.
How SprintBuild is built
SprintBuild runs on Next.js with the App Router, the AI SDK for streaming agent responses, and the Vercel AI Gateway for model routing. Each generated app boots inside a Vercel Sandbox — an ephemeral Firecracker microVM with isolated networking, file system, and process tree.
Authentication, project history, and per-user file storage are backed by Supabase with row-level security, so a user can only ever see and modify their own work.
The full source for the underlying agent runtime is open-source. If you'd like to see how a specific feature works, the vibe-coding-platform repo is the place to start.
