Quick verdict
Base44 and Bolt.new sound like competitors but are subtly different products. Base44 is a complete platform — backend, frontend, database, auth, hosting, and AI agent all in one place. Bolt.new is an AI-powered browser-based development environment built on StackBlitz's WebContainer technology — you write code in the browser, the AI generates and edits files, and your output is a normal project that deploys to your own infrastructure.
Choose Bolt.new if you want to own real code from minute one and your team is comfortable wiring up Supabase, Netlify, or Vercel for the runtime side. Choose Base44 if you want the entire stack hosted, integrated, and one-click. Both are AI-native. Both have the same class of regression-loop problem on long sessions. The decision is mostly about whether you want a platform or a tool.

True cost to ship a working app at moderate scale (≈10k MAU):
- Base44: $50–$200/month subscription plus credit overages during build. Runtime is included up to plan limits. Real-world build phase: $200–$600/month total.
- Bolt.new: $20–$200/month subscription, plus your own Supabase ($0–$25/month), plus your own Netlify or Vercel ($0–$20/month). Runtime is your responsibility, not Bolt's. Annualized: $500–$3,000.
Bolt is meaningfully cheaper at runtime because it does not host you. It is also a smaller scope of tool — Bolt does not pretend to be your hosting provider, while Base44 does. If you already have Supabase and Vercel, Bolt is a clear cost win. If you do not want to manage those, Base44's one-bill model is friendlier.
Feature parity
| Feature | Base44 | Bolt.new |
|---|---|---|
| AI-native generation | Native | Native |
| Output language | React + Deno (Base44 flavor) | Any (Next.js, Vite, React, Svelte, Astro, etc.) |
| Database | Built-in entity store | None (bring your own — Supabase typical) |
| Authentication | Email, OAuth, SSO | None (bring your own) |
| Hosting | base44.app or custom domain | Netlify deploy from Bolt; or push to GitHub |
| Server-side rendering | No (CSR by default) | Yes (any framework you choose) |
| Code export | Yes (with SDK references) | Yes (clean, owned from minute one) |
| Real Node.js runtime | No | Yes (WebContainer) |
| Terminal access | No | Yes (real terminal in browser) |
| Package install (npm) | Limited via Deno | Yes (full npm in WebContainer) |
| GitHub integration | Limited | First-class (push from browser) |
| Deploy targets | Base44 only | Netlify, Vercel, anywhere |
| Multi-framework support | React only | Any JavaScript framework |
| AI agent | Native generation | Native generation |
| Integrated backend | Yes (Deno functions) | No (bring your own) |
Code ownership and lock-in
Bolt.new wins this category cleanly.
Bolt.new is, fundamentally, "an AI that writes code in your project." There is no platform layer that owns your runtime, your database, or your auth. From minute one, the code is yours, the structure is normal, and the deploy target is whatever you choose. Bolt's lock-in is roughly zero — you can paste the same prompt into Cursor or Lovable tomorrow and continue.
Base44 offers code export, but the exported project carries SDK references, entity helpers, and runtime assumptions that bind it to Base44's infrastructure. Migration to a normal stack takes 1 to 4 weeks of cleanup. We document this in base44-export-code-guide.
If your team has any concern about platform risk, Bolt's architecture is the right answer. The trade-off is that Bolt does not give you the integrated platform features that make Base44 productive in the first hour.
Speed to working prototype
Base44's time from prompt to clickable CRUD app with auth and database: 2 to 6 hours. Bolt.new's time from prompt to clickable CRUD app with auth and database: 4 to 12 hours.
Bolt is slower because the database, auth, and deployment are not bundled. You spend 1 to 3 hours wiring Supabase, configuring auth, and deploying to Netlify before you have an end-to-end working app. Base44 skips all of that — the platform provides everything.
For a "this afternoon" deadline, Base44 wins. For a "this weekend" deadline, the gap closes. For a "this month" deadline, Bolt wins because the code you build on it is more maintainable.
Production readiness
Base44's production gaps:
- CSR-by-default makes SEO impossible without manual SSR engineering.
- AI regression loops at scale.
- No SLA on lower tiers.
- Vendor lock-in via SDK and entity helpers.
- Production tooling (staging, rollback, observability) is light.
Bolt.new's production gaps:
- WebContainer is a development tool, not a production runtime — you must deploy elsewhere.
- AI agent quality varies; Bolt sometimes generates code that compiles but is structurally messy.
- No native testing harness — you wire it up yourself.
- Token costs spike fast on long sessions.
- Bolt has had availability issues during high-load events; the WebContainer is a complex piece of infrastructure.
Both ship production apps every day. Bolt's production deployments are normal Next.js or Vite apps on Vercel/Netlify, which is a well-understood stack. Base44's production deployments live on Base44, which centralizes risk.
Best fit for use case

| Multi-framework projects | Bolt.new | Supports any JS framework |
| Internal tool with auth + DB | Base44 | Backend is included |
| SaaS product needing SSR | Bolt.new | Pick Next.js, get SSR |
| App you intend to deploy to your own AWS/GCP | Bolt.new | Code is portable |
| AI feature-heavy app | Tie | Both have AI native |
| Solo founder shipping fast | Base44 | One platform, one bill |
| Team with senior developers | Bolt.new | Real dev workflow |
| Educational / learning project | Bolt.new | Real code is more pedagogical |
| Mobile native build (Capacitor) | Tie | Both wrap; neither is native |
The honest negative
Where Base44 is genuinely worse than Bolt.new:
- Vendor lock-in is structural. Bolt has roughly zero. Base44 has SDK and entity helper coupling that takes weeks to unwind.
- Multi-framework choice. Bolt supports anything. Base44 supports React.
- Real terminal and npm. Bolt gives you a real Node environment. Base44 gives you Deno functions.
- Code structure. Bolt's output looks like a normal project. Base44's output looks like a generated platform output.
- Deployment flexibility. Bolt deploys anywhere. Base44 deploys to Base44.
- GitHub workflow. Bolt pushes to GitHub natively. Base44 treats Git as a secondary citizen.
Where Bolt.new is genuinely worse than Base44:
- No backend. You bring your own database, auth, and hosting. Base44 includes all three.
- More moving parts. Bolt + Supabase + Vercel is three vendors. Base44 is one.
- WebContainer limitations. Memory and CPU caps in the browser sandbox slow down or break large projects.
- Less integrated AI agent. Base44's agent knows about the platform's data model. Bolt's agent has to be told.
- No built-in auth UX. You wire up Supabase Auth or similar yourself.
- Reliability of WebContainer. Bolt has had outages and slowdowns from WebContainer issues. Base44's runtime is more boring and more reliable.
If you want to think of this comparison clearly: Bolt is "AI in a real dev environment," Base44 is "AI on a hosted platform." Different tools, overlapping use cases, different teams.
