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
Lovable
AI app generator with hosted runtime
- Polished Supabase integration for auth, database, and storage.
- Dev Mode lets you edit generated code without leaving the product.
- GitHub sync so you can take ownership of the source.
- Strong template gallery and an active community.
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.
Lovable: hosted runtime
Lovable runs your generated app on a managed runtime that abstracts the underlying server. It's simpler, but you have less control over the environment and what can run inside it.
Feature-by-feature comparison
Pulled from Lovable's public docs and pricing page on May 23, 2026. “Partial” means the capability exists with caveats; hover for the qualifier.
| Feature | SprintBuild | Lovable |
|---|---|---|
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 model under the hood. |
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 Hosted runtime, not a per-session Linux sandbox. |
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 |
File explorer Browse the generated source tree and read any file. | Yes | Yes Via Dev Mode. |
Streaming command logs Real-time stdout/stderr for every command the agent runs. | Yes Live stdout/stderr per command. | Partial Build logs only; no per-command stream. |
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. | Yes Auto-fix loop on errors. |
GitHub export Push generated source to your own GitHub repo. | Partial Manual export today; native push on roadmap. | Yes Bidirectional sync. |
One-click deploy Ship the running sandbox to a publicly accessible URL. | Partial Sandbox preview URLs are public; native Vercel deploy on roadmap. | Yes Lovable Cloud, included. |
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. | Yes 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×. | Yes Credits but with hard daily/monthly caps. |
Where Lovable shines
- Polished Supabase integration for auth, database, and storage.
- Dev Mode lets you edit generated code without leaving the product.
- GitHub sync so you can take ownership of the source.
- Strong template gallery and an active community.
Where Lovable struggles (vs SprintBuild)
- Hosted runtime — less flexibility than a real Linux sandbox.
- Single-model under the hood; no per-turn model choice.
- Free tier is heavily metered (5 daily credits, max 30/month).
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.
Lovable
Free, Pro $25/mo, Business $50/mo. Credit-based. Free = 5 daily / 30 monthly. Pro = 100 monthly + 5 daily. Business adds SSO and data opt-out.
When to pick SprintBuild vs Lovable
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 Lovable if
- Polished Supabase integration for auth, database, and storage.
- Dev Mode lets you edit generated code without leaving the product.
- GitHub sync so you can take ownership of the source.
- Strong template gallery and an active community.
Frequently asked questions
Is SprintBuild a good Lovable alternative?+
SprintBuild is a good Lovable 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. Lovable's strengths are polished supabase integration for auth, database, and storage. and dev mode lets you edit generated code without leaving the product., so the right pick depends on which trade-offs matter to your build.
What is the main difference between SprintBuild and Lovable?+
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. Lovable uses a hosted runtime that abstracts the underlying environment, which trades some flexibility for faster startup or simpler hosting.
How does SprintBuild pricing compare to Lovable?+
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. Lovable pricing: Free, Pro $25/mo, Business $50/mo. Pricing model: Credit-based. Free = 5 daily / 30 monthly. Pro = 100 monthly + 5 daily. Business adds SSO and data opt-out.
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 Lovable 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. Lovable typically runs Claude Sonnet (default), so the choice is narrower or hidden behind orchestration.
