#1★ TOP PICK
Dyad
A free desktop app builder with Supabase built in, any model, and your code on your own disk.
93
OPEN SOURCEApache-2.0 (src/pro under FSL-1.1-ALv2)SELF-HOSTLOCAL-FIRST
Dyad is a local, open-source AI app builder that describes itself as an alternative to Lovable, v0 and Bolt that runs on your own computer. The workflow is close to Lovable's: you chat, it builds and previews the app, versions are saved automatically, and when you ask for a backend feature it offers to connect Supabase for auth, database and server functions, the same backend Lovable's own migration guide points to. The difference is ownership: every project is a regular Git repository in a folder on your machine (~/dyad-apps by default), and you choose the model, from a free-tier Gemini key, OpenAI, Anthropic, OpenRouter or a ChatGPT subscription to local models through Ollama or LM Studio. It starts from React and Vite or Next.js templates, supports Neon as well as Supabase, and its import feature is built for apps from Lovable, v0 or Bolt.
⌁ Dyad runs anywhere Node.js runs, and its FAQ suggests a cloud model such as Gemini or OpenRouter if your machine is not powerful. Local models through Ollama or LM Studio are optional; Dyad's own docs warn they are resource-intensive and that smaller models may struggle to follow its instructions.
Strengths
- +Each project is a normal Git repository on your own disk; no workspace, credits pool or hosting account stands between you and your code
- +Supabase integration for auth, database and server functions, so a Lovable app on Supabase has a natural home
- +Any model, including a free-tier Gemini key, a ChatGPT subscription or a local model
- +Very active: v1.18.0 shipped on 5 October 2026, and the repository has about 21.7k GitHub stars
Trade-offs
- −You install a desktop app plus Node.js and run the preview on your own machine; macOS and Windows are supported, while Linux is experimental and does not auto-update
- −No hosting, managed database or security certifications of its own; deploying, backups and access control become your job
- −Importing an existing app is marked experimental and supports Node.js-based JavaScript apps with an npm run dev script
- −The Pro features in the repository's src/pro folder are fair-source (FSL-1.1), not open source, and the free agent mode is limited to 20 messages a day
Free and open source; bring your own API key or a ChatGPT subscription, or run a local model. The free Basic Agent is listed at 20 messages a day. Optional Dyad Pro is $20/month with 200 AI credits, and Dyad Max $79/month with 900. Verified on dyad.sh/pro 2026-10-06. #2
bolt.diy
An open-source, browser-based app builder you run yourself, with any model.
78
OPEN SOURCEMITSELF-HOSTLOCAL-FIRST
bolt.diy is the official open-source version of Bolt.new, published under StackBlitz Labs and maintained as a community project. You run it on your own machine (Node.js and pnpm, or Docker) and get a browser-based builder with chat, an editor, a terminal and a live preview of Node.js-based web apps, choosing the model for each prompt from more than 20 providers, including Ollama and LM Studio for local models. It has a Supabase integration, downloads any project as a ZIP, connects to Git, and deploys to Netlify, Vercel or GitHub Pages. One catch is specific to it: apps run inside StackBlitz's WebContainer API, which StackBlitz licenses separately and which needs a commercial licence for production use in a for-profit setting.
⌁ bolt.diy itself is light: a local Node.js server or Docker container serving a browser UI. With a cloud model it runs on modest hardware. Local models through Ollama or LM Studio need a capable GPU or plenty of unified memory, and the README lists better performance for smaller models as planned work.
Strengths
- +Runs on infrastructure you control, from a laptop to a Docker host
- +Choose the model per prompt from more than 20 providers, including local Ollama and LM Studio
- +Supabase integration, ZIP download, Git, and deploys to Netlify, Vercel or GitHub Pages
- +An active community project: about 19.9k GitHub stars, with commits landing this week
Trade-offs
- −Its runtime, the WebContainer API, is proprietary; StackBlitz requires a commercial licence for production use in a for-profit setting
- −No one-click install: you run it from source with Node.js 22.12+ and pnpm, or Docker; the last tagged release and desktop build (v1.0.0) date from May 2025
- −Its README lists the move from single model calls to an agent-based system as still in progress, so expect more hand-holding than Lovable's agent
- −Aimed at people comfortable with a terminal; there is no managed hosting, backend or visual editor of the kind Lovable provides
Free and open source (MIT); you pay your model provider, or nothing beyond hardware with a local model. StackBlitz requires a separate commercial WebContainer API licence for production use in a for-profit setting; prototypes and proofs of concept do not need one. #3
Google AI Studio
Google's free, hosted prompt-to-app builder, if a Gemini-only tool and Google's free-tier terms suit you.
25
SOURCE-AVAILABLEProprietary (hosted service)
If what you value in Lovable is that someone else runs everything, Build mode in Google AI Studio is the closest hosted option at no cost. It turns a prompt into a full-stack web app (a React front end and a Node.js server by default) or a native Android app in Kotlin and Jetpack Compose, with a live preview in the browser, and it can provision Firebase Firestore and Firebase Authentication, sync two ways with GitHub, export a ZIP, and deploy to Cloud Run. Google's billing page says AI Studio usage is free of charge unless you link a paid API key. The trade-offs: it is built around Google's Gemini models, and on the free tier Google's terms say your prompts and outputs may be used to improve its products and may be read by human reviewers.
Strengths
- +No subscription and no credits to budget: free in the browser unless you link a paid key
- +Full-stack by default (React plus a Node.js server), and native Android apps as well
- +Two-way GitHub sync and ZIP export; a downloaded app runs on any host once you set GEMINI_API_KEY
- +Firebase Firestore and Google sign-in can be provisioned for you
Trade-offs
- −Built around Gemini; Google's Build mode guide describes no other model provider
- −On the free tier Google may use your prompts and outputs to improve its products, human reviewers may read them, and its terms say not to submit sensitive or confidential information
- −Firebase rather than Supabase, so a Lovable app's backend does not carry across directly
- −A hosted Google service you cannot self-host; deploying from AI Studio means Cloud Run, billed by usage
Free to use unless you link a paid API key; deploying to Cloud Run is billed by Google Cloud based on usage, and apps that call paid models can incur costs. Verified on ai.google.dev 2026-10-06.
