Open-source alternatives to Lovable

3 genuinely open-source alternatives. The projects are compared by license, workflow, self-hosting, and pricing.

Why look for a Lovable alternative?

Lovable combines natural-language prompts, AI code generation, live previews, backend integrations, application editing, and deployment in a browser-based workflow. People look for alternatives when they want to run the builder locally, use their own AI API keys, support multiple providers, self-host, avoid platform-specific credits, or keep more control over generated code and prompts.

Reflex

Open-source full-stack Python framework with an AI app builder.

Reflex combines an Apache-2.0 full-stack Python framework with Reflex Build, an AI-assisted browser workflow for prompts, live previews, code editing, testing, integrations, Git, and deployment. Generated applications remain standard editable Reflex source code.

Apache-2.0Self-hosted

Pricing: Open-source Apache-2.0 framework; managed builder, hosting, and enterprise functionality may be commercial.

Apache-2.0 open-source framework
Full-stack applications in Python with editable generated source
AI prompt-to-app builder, live preview, testing, Git, and deployment tooling
Uses the Reflex framework rather than standard React architecture
Less suitable if you specifically want a JavaScript or TypeScript stack
Different ecosystem from Lovable's common React and Supabase workflows

Dyad

Local AI app builder with bring-your-own-model support.

Dyad is a local AI app builder designed as an alternative to Lovable, Bolt, and v0. It runs on your own computer, generates and modifies applications through natural-language prompts, and supports your own AI providers and API keys.

Apache-2.0 core; Functional Source License 1.1 Apache 2.0 Pro

Pricing: Open-core model: the core is Apache-2.0, while Pro functionality uses a separate fair-source license; model-provider costs may apply.

Runs locally with no mandatory account
Bring your own AI API keys and support multiple providers
Generated code stays under your control with an active community
Pro functionality uses a separate fair-source license
Requires your own model/API setup for many workflows
Less integrated hosting than Lovable and desktop-first rather than browser-first

Frontman

Visual AI coding agent for editing running web applications.

Frontman is a visual AI coding agent that works inside a running web application. It understands the live DOM, component tree, CSS, routes, source maps, and server logs, then writes requested changes to real source files.

Apache-2.0 integrations; AGPL-3.0 server with AI Supplementary TermsSelf-hosted

Pricing: Source-available combined product with self-hosting; server AI Supplementary Terms add restrictions and hosted services may be commercial.

Select visual elements and edit applications directly from the browser
Writes changes to real source files and understands application state
Supports Next.js, Astro, React, Vue, Svelte, and Vite with BYOK models
Combined product is source available rather than fully OSI-compliant open source
Primarily designed for editing existing applications
