Sitios visuales responsivos con componentes reutilizables y datos de CMS; la gestión de agencia se vuelve tu propio proceso.

licenseAGPL-3.0+

runsyour machine or their cloud

installHosted signup or desktop app; alternatively export the project or deploy the self-hosted builder/site

enginesWebstudio Inception AI and MCP integrations; the hosted model provider is not named in official documentation

dataProjects and assets live in Webstudio Cloud when hosted there; export/self-host routes produce source or static assets under the user's deployment

the catch vs DudaWebstudio has no built-in agency billing, white-label client portal or managed multi-client workflow.

setupThe free cloud plan publishes only to a Webstudio subdomain; a free custom domain requires export or self-hosting

Plasmicopen sourcewebself-hostedthey host it

Componentes reutilizables, colaboración y proyectos ilimitados gratis; la entrega al cliente está menos adaptada a agencias.

licenseMIT AND AGPL-3.0

runsyour machine or their cloud

installHosted signup; optional npm-installed Plasmic CLI for React code generation and deployment in your own repository

enginesPlasmic AI (beta); the official site does not name its underlying model provider

dataHosted projects and CMS records in Plasmic Cloud; codegen writes React components plus plasmic.json and plasmic.lock into the user's repository

the catch vs DudaPlasmic lacks Duda's agency-specific white-label dashboard, client billing and standardized multi-site handoff workflow.

setupFree hosted output keeps Plasmic branding; codegen/self-deployment requires a Node/React project and deployment workflow

Silexopen sourcewebself-hostedthey host it

Un editor visual gratuito para sitios de clientes con exportación; los flujos de trabajo de secciones reutilizables son básicos.

licenseAGPL-3.0+

runsyour machine or their cloud

installUse the hosted editor with a GitLab login, install the desktop alpha, or run the official Docker setup

enginesOptional desktop MCP workflow can connect to Ollama, OpenCode, Goose or Claude Code

dataProject JSON and assets in GitLab, FTP or local storage; publishing produces ordinary static HTML, CSS and JavaScript

the catch vs DudaSilex's reusable sections, permissions, collaboration and client handoff are basic beside Duda's agency workflow.

setupThe stable hosted route starts with a GitLab account; the desktop build is still labelled alpha

why people still pay for Duda

People still pay for Duda because the page renderer is reproducible, but customers pay to avoid becoming their own hosting and browser-compatibility team. The recurring cost buys responsive rendering, forms, domains, certificates, deploys, backups, template maintenance, and browser regressions, not just the visible interface. If none of that applies to you, any pick above saves $300 a year.

questions
Is there a free alternative to Duda?

Yes: Webstudio, Plasmic, Silex and 2 more. Every tool on this page is either open source or genuinely free to use long-term: no trials, no crippled tiers.

Should I just build my own Duda?

Our verdict is PARCIAL. The core loop is buildable, but a dependable replacement becomes a real weekend or multi-day project. For Duda, build and manage one client-ready responsive site from reusable sections. The hard boundary is agency workflow, white-labeling, hosting, client permissions, and support, plus editor polish, hosting, templates, and ecosystem. If you'd rather build, the exact one-shot prompt is free at puedovibecodearlo.app/duda.
