Bolt (StackBlitz) vs Base44
A plain-English comparison to help you choose between them.
Bolt and Base44 are both prompt-to-app builders, but ship-it versus learn-it is the split, and the honest question is who will touch the result afterwards. Pick Bolt when you want the code visible and editable as you build: a real runtime in the browser, a terminal when you want it, framework choice, and output a developer can harden for production. Pick Base44 when the goal is a running product and nobody wants to meet the code: the database, authentication, storage and hosting are bundled, and editing stays visual after the first prompt. Builders who will grow into the code choose Bolt; builders who never want to are exactly who Base44 is for.
Both tools chosen. Compare is enabled.
Side by side
- Summary
Bolt builds, runs and deploys full-stack web apps from a prompt, entirely in the browser: the agent generates the project, a real runtime executes it instantly, and the live preview updates as you talk. Packages install in seconds and the terminal is right there when you want it.
It spans the modern JavaScript framework landscape, wires databases and auth through integrations, and deploys from the same tab. The in-browser runtime is the distinctive piece: no cloud VM, no local setup, just code running where you prompt.
MoreLess
It is a prototyping and building surface with real code underneath; production hardening remains a developer's job.
- Best for

- Modern JavaScript frameworks scaffolded from a description
- Database and auth wired through integrations
- Deploying the prototype from the same tab
- Cost
- Freemium (Free tier + paid plans)
- Ease
- Openness
- Hosted service
- Data
- Projects run in-browser on StackBlitz infrastructure; exported code is yours to take anywhere.
- Summary
Base44 is an AI app builder that generates full-stack applications from plain-language prompts. What sets it apart from the other prompt-to-app tools is where it draws the line for the user: the database, authentication, file storage and hosting are built in rather than connected as external services, so a non-technical builder never has to configure a server or a database at all.
After a prompt produces the first version, editing carries on visually rather than in code, and on higher tiers the underlying code-generation model can be switched. The pitch is the vendor's own framing: backend and storage, built in, with hosting and authentication included, so the app runs without any separate infrastructure to stand up.
MoreLess
There is a free tier plus paid monthly tiers, published first-party, with a discount on annual billing. Base44 has been acquired by Wix.
- Best for
- Non-technical builders who never want to meet a backend

- Built-in database, authentication, file storage and hosting
- Visual editing after the first version is generated
- Switching the code-generation model on higher tiers
- Cost
- Freemium (Free tier + paid plans)
- Ease
- Openness
- Hosted service
- Data
- The backend, authentication, data and business logic live on Base44's servers behind its SDK, and export is frontend-only, with ZIP or GitHub export itself a paid-tier feature. Treat the platform as where the application and its data live, and weigh that against any obligation to hold data elsewhere. Base44 has been acquired by Wix.

By area
Where each one pulls ahead, area by area.
| Area | Bolt (StackBlitz) | Base44 |
|---|---|---|
| By job | ||
| Founders & entrepreneurs | Bolt suits the throwaway phase of finding what is worth building, running a real project inside the browser so a demo is a working product rather than slides | Base44 removes the part that usually stops a non-technical founder, though the data and logic then live behind its SDK on its servers, which matters the day a portable codebase has to be handed to an engineer |
| Product management | Bolt output is a working argument rather than a shippable artefact: anything customer-facing needs a developer to harden it first | Base44 needs no technical literacy to reach a running product |
| By task | ||
| Coding & software development | Bolt scaffolds full-stack apps with the code fully visible, packages installing in seconds and the terminal there when you want it, which is what a developer who will then edit it as real code needs | Base44's export is frontend-only and gated behind a paid tier, so anything built here stays tied to the platform for its backend |
| Design, UI & prototyping | Bolt prototypes function with default aesthetics, so what comes back is a working app rather than a designed one | Base44 generates functioning apps rather than design files, and the interface follows from the prompt rather than from a design |
Common questions
Which gets a non-technical builder to a working app faster?
Base44, and by design: it assumes no technical literacy, bundles the backend and hosting, and never shows you a repository. Bolt is also prompt-driven and beginner-friendly at the start, but its value assumes you will eventually read or edit the code it writes. If the finish line is an app your team uses, not a codebase you own, Base44 is the shorter path.
Can either produce something production-ready?
Neither is production-safe unaided, but they fail differently. Bolt outputs real code with known gaps in validation, session handling and secret management, so a developer hardens it before customers touch it. Base44 hosts and runs the app for you, but the backend stays behind its SDK on its servers, so production-readiness becomes a question of platform trust and lock-in rather than code review.
What does each cost beyond the free tier?
Both are freemium. Bolt's free tier covers trials, and its paid tiers meter usage by tokens, so heavy iteration is what raises the bill. Base44 sells flat monthly tiers, cheapest on annual billing, with higher tiers adding export and model switching. A prototyping burst is cheap on either; a long-lived product favours Base44's predictable tiers unless a developer takes Bolt's code and self-hosts.
