LessCMS is a lightweight CMS for businesses and agencies, built in Poland. It combines a visual drag-and-drop page editor (78 widgets, separate desktop/tablet/phone settings) with a read-only headless API, so one project can be a full website on your own domain or a content backend for Nuxt or...

As answered by people managing CodeSandbox and LessCMS.io.
LessCMS.io's answer:
LessCMS.io's answer:
PHP, Vue 3, Nuxt, Node.js, MySQL, MongoDB, Cloudflare (CDN, Workers, Turnstile), OpenAI API.
LessCMS.io's answer:
LessCMS is both a visual website builder and a headless CMS in one product. The same project can be a finished website on your own domain — edited with a drag-and-drop editor — or a content backend for your own Nuxt or Next.js front end via API. Multilingual content, AI translation, SEO, forms and cookie consent are built in, so there are no plugins to install, update or secure.
LessCMS.io's answer:
Compared to WordPress: no plugins, no updates, no security patches — everything important is built in and hosted for you. Compared to Wix or Webflow: your content is also available through a headless API, and multilingual sites with AI translation are included instead of being expensive add-ons. Compared to Strapi or Contentful: non-technical editors get a real visual page editor, not just forms. Pricing starts with a free plan and flat monthly fees with no setup costs or long-term contracts.
LessCMS.io's answer:
Web agencies and freelancers who build websites for clients and want to hand over a CMS that clients can edit themselves without breaking anything. Small and mid-sized businesses that want a fast, multilingual company website without maintaining WordPress. Developers who need a headless CMS with a visual editor for their Nuxt or Next.js projects.
LessCMS.io's answer:
LessCMS was built by Softmasters, a software house from Bielsko-Biała, Poland. After years of building and maintaining client websites on WordPress, we were tired of plugin updates, security patches and clients breaking layouts. We built LessCMS as the tool we wanted ourselves: a visual editor clients can safely use, a headless API for developers, and everything important built in. It is part of the LessTools family, together with LessCommerce for e-commerce and LessSEO.
