The open source Lovable alternative you can self-host, rebrand and resell

Better depends on the job. Lovable is strong at fast hosted prototyping, and if a polished front end in an afternoon is the goal it is hard to beat. If you need to own, host or resell the builder itself, or you need generated apps that are server-rendered so search engines and AI answers can read them, a different tool wins. The two open source routes people take are Creable, which you self-host and can rebrand and resell, and dyad, which runs locally on your own model keys.

Yes. Creable is MIT licensed and free to run, and you pay only for API usage, starting with 50 free credits. dyad and bolt.diy are also free and use your own model keys. Be precise about what free means here: the builder code costs nothing in all three cases, but the AI generation itself is paid somewhere, either through the Totalum API or through your own provider account, and that is true of every option on this page including Lovable's free plan.

They are built for different habits. Replit is an all-in-one collaborative workspace with a real editor, an autonomous agent and its own hosting, so it suits people who want to stay close to the code and work with others in the same environment. Lovable is narrower and faster for front-end-first prototypes. Both are hosted and closed, so neither can be self-hosted or resold, which is the line where an open source builder like Creable is a different kind of answer rather than a better version of the same one.

Bolt.new runs the full stack in the browser and is strong for quick prototyping when you want to see a backend working immediately. Lovable is stronger on polished UI generation and its Supabase integration is smoother for a database-backed front end. Both are rented: you use the builder inside their product and you cannot host or modify it. Creable differs on exactly that point, because the builder is MIT code you run yourself.

For fast validation and prototypes, yes, provided the per-message pricing fits your volume and you do not need to own the builder. Three situations are where people outgrow it: per-message cost that gets unpredictable at scale, no way to modify or self-host the builder, and client-rendered output that is weak for SEO. If none of those apply to you, Lovable is a reasonable place to stay.

Lovable itself is proprietary and has no self-hosted edition. Creable is an open source builder that follows the same workflow of prompt, live preview, iterate and publish, published under the MIT license at github.com/totalumlabs/lovable-alternative. You can read every line of the builder, run it on your own infrastructure and change anything in it.

The best free and open source Lovable alternative is Creable, an MIT-licensed AI app builder you can self-host, rebrand and resell, with hosting, a database, auth and custom domains included through a single API key. It reproduces the Lovable workflow of prompt, preview, iterate and publish, but the builder itself is source code you can host on your own servers, restyle, put your own brand on and sell to your own customers.

Yes. Creable is a standard Next.js 16 application, so it runs anywhere Next.js runs: Vercel, Docker, Railway, Render, Fly.io or a plain virtual machine with Node 20 or newer. Clone it, set one environment variable and run npm run build and npm start. The generated apps are hosted by the Totalum API, so your server only ever runs the builder itself.

The builder is free and MIT licensed, with no seat fees and no commercial-use restriction, so you can sell what you build on top of it. The platform work behind it, the coding agent, the sandboxes, hosting, databases and deploys, is billed through the Totalum API, and the first 50 AI credits are free. There is no second vendor to pay: one key covers all of it.

Yes, and the MIT license is explicit about it. The repo ships with no login by design, so you add your own provider, make the two guards in src/app/api/vcaas/_shared.ts real, map every project to a user, then add Stripe and meter credits per run. The agent status response reports the credits each run spent, which is what lets you price above your cost.

Yes. The whole builder is a thin client in front of one API, so you can either embed this UI inside your product or call the same endpoints from your own interface. The minimum flow is a key-holding server proxy, POST /projects/launch, polling the agent status, then a deploy call. Isolated projects per tenant, hosting, databases and domains are handled on the platform side.

Yes. Each generated app is a server-rendered Next.js project with its own managed database, and the builder includes a table UI for browsing and editing that data, with filters, linked records and file uploads. Authentication, file storage and per project secrets are available to generated apps as well, so the output is a working product rather than a front end waiting for a backend.

The difference is architectural rather than a matter of degree. A client-rendered single page app sends an empty HTML shell plus a JavaScript bundle, so a crawler or an AI search engine has to execute scripts before it sees any content. Creable generates server-rendered Next.js, so complete HTML, per-page metadata, canonicals and sitemaps arrive in the first response, and database-backed pages can each be their own indexable URL.

The Totalum API routes each prompt to the best available coding model by default, so you do not have to choose one or hold model keys of your own. The composer's run options let you pick the model, the effort level and fast mode per prompt when you do want to steer it.

No. Creable is a thin client in front of the Totalum API, and the agent, the sandboxes and the hosting all run on the platform side, so it needs a network connection and a key. If what you want is a local-first tool that runs against your own model keys, dyad or bolt.diy are the better fit and we would point you there.
