Comparison
SprintBuild vs Bolt.new: which AI coding platform fits your build?
A side-by-side comparison of SprintBuild and Bolt.newcovering execution model, supported AI models, pricing, and the features that matter most when you ship from a prompt. Verified against each vendor's public docs on May 23, 2026.
Last verified: May 23, 2026
SprintBuild
Sprint from idea to running app, powered by AI and a real sandbox.
- Real Vercel Sandbox per session (Linux, full shell, ports)
- Claude, GPT, and Grok via the Vercel AI Gateway
- Credit-based pricing with rollover
- First-class Supabase auth + RLS scaffolding
Bolt.new
Browser-based AI dev environment
- Zero install — everything runs in your tab via WebContainers.
- Fast time-to-preview thanks to in-browser execution.
- GitHub export plus deploy to Netlify or download.
- Strong template ecosystem inherited from StackBlitz.
How they execute generated code
SprintBuild: cloud sandbox
Every session boots a Vercel Sandbox — a Firecracker microVM with full Linux, real networking, and up to 2 exposed ports. The agent installs dependencies, runs scripts, and starts a dev server like it would on any production box. What you see in preview is what would actually ship.
Bolt.new: browser WebContainer
Bolt.new runs a Node.js environment inside your browser tab using WebContainers. Startup is instant and there's nothing to install, but the environment can’t run native binaries, has tighter resource ceilings, and behaves differently from a real Linux box.
Feature-by-feature comparison
Pulled from Bolt.new's public docs and pricing page on May 23, 2026. “Partial” means the capability exists with caveats; hover for the qualifier.
| Feature | SprintBuild | Bolt.new |
|---|---|---|
Prompt to full-stack app Describe an app in natural language and the agent scaffolds, runs, and previews it. | Yes Native, every session. | Yes |
Multi-model support Choose between Claude, GPT, Grok, and others without leaving the product. | Yes Claude Opus 4.6, Sonnet 4.6, GPT-5.3 Codex, Grok 4.1 via Vercel AI Gateway. | No Single backend model. |
Real cloud sandbox per session Each session runs in an isolated, ephemeral VM with full Linux, networking, and a real package manager. | Yes Vercel Sandbox (Firecracker microVM) per session. | Partial WebContainer in your browser tab — no real Linux. |
Live iframe preview See the running app the moment a dev server boots; reload as the agent edits files. | Yes Streamed from the sandbox dev server. | Yes Native; runs in the same tab. |
File explorer Browse the generated source tree and read any file. | Yes | Yes |
Streaming command logs Real-time stdout/stderr for every command the agent runs. | Yes Live stdout/stderr per command. | Yes Terminal panel for in-browser commands. |
Auto-fix loop on errors Build failures and runtime errors stream back to the agent, which patches them without manual prompting. | Yes Errors stream back into the agent loop. | Partial Error feedback prompts the model. |
GitHub export Push generated source to your own GitHub repo. | Partial Manual export today; native push on roadmap. | Yes |
One-click deploy Ship the running sandbox to a publicly accessible URL. | Partial Sandbox preview URLs are public; native Vercel deploy on roadmap. | Yes Deploy to Netlify. |
Supabase integration First-class hooks for Supabase auth, database, and storage in generated apps. | Yes Auth, Postgres, and Storage with RLS scaffolded by the agent. | Partial Manual setup; works but not first-class. |
Transparent credit-based pricing Pay for what you use, with rollover and the same models on every tier. | Yes All models on every tier; credits roll over up to 2×. | Partial Token-based, not credit-based. |
Where Bolt.new shines
- Zero install — everything runs in your tab via WebContainers.
- Fast time-to-preview thanks to in-browser execution.
- GitHub export plus deploy to Netlify or download.
- Strong template ecosystem inherited from StackBlitz.
Where Bolt.new struggles (vs SprintBuild)
- WebContainer environment limits what can run (no native binaries, limited concurrency).
- Token-based usage that can burn through credits unpredictably during long sessions.
- No per-turn model choice; runs Bolt’s configured backend model.
Pricing snapshot
SprintBuild
Free, Hobby $20/mo (1,000 credits), Pro $50/mo (3,000 credits), Team $200/mo (15,000 pooled credits). All models on every tier. Unused paid credits roll over up to 2× the monthly grant.
Bolt.new
Free trial, Pro from $20/mo, scales with token usage. Token-based. Pro tiers add monthly tokens; heavy generation can burn the budget quickly.
When to pick SprintBuild vs Bolt.new
Pick SprintBuild if
- You want a real Linux sandbox per session, not a hosted runtime.
- You want Claude, GPT, or Grok per turn, not a fixed backend.
- Predictable credit pricing without daily caps matters.
- Supabase auth + RLS scaffolding is part of your stack.
Pick Bolt.new if
- Zero install — everything runs in your tab via WebContainers.
- Fast time-to-preview thanks to in-browser execution.
- GitHub export plus deploy to Netlify or download.
- Strong template ecosystem inherited from StackBlitz.
Frequently asked questions
Is SprintBuild a good Bolt.new alternative?+
SprintBuild is a good Bolt.new alternative if you need a real Linux sandbox per session, the ability to switch between Claude, GPT, and Grok per turn, and credit-based pricing without daily caps. Bolt.new's strengths are zero install — everything runs in your tab via webcontainers. and fast time-to-preview thanks to in-browser execution., so the right pick depends on which trade-offs matter to your build.
What is the main difference between SprintBuild and Bolt.new?+
The biggest architectural difference is execution. SprintBuild runs each session in a Vercel Sandbox — a real Firecracker microVM with full Linux, networking, and a real package manager. Bolt.new uses a browser-based WebContainer that runs Node.js inside your tab, which trades some flexibility for faster startup or simpler hosting.
How does SprintBuild pricing compare to Bolt.new?+
SprintBuild starts at $20/month for the Hobby plan with 1,000 credits and scales to $200/month for Team with 15,000 pooled credits. Bolt.new pricing: Free trial, Pro from $20/mo, scales with token usage. Pricing model: Token-based. Pro tiers add monthly tokens; heavy generation can burn the budget quickly.
Can I export my code from SprintBuild?+
Yes. SprintBuild keeps the full source visible in the file explorer during every session, and projects you create are saved to your account so you can revisit them later. Native GitHub push is on the roadmap; for now you can copy or download files manually.
Which models does SprintBuild support that Bolt.new doesn't?+
SprintBuild routes through the Vercel AI Gateway, so you can pick between Claude Opus 4.6, Claude Sonnet 4.6, GPT-5.3 Codex, and Grok 4.1 Reasoning per turn. Bolt.new typically runs Claude (Bolt-managed), so the choice is narrower or hidden behind orchestration.
