Contismo - 2026 Pricing, Features, Reviews & Alternatives

Contismo is a web-based content management platform built around speed, flexibility, and publishing workflows. Alongside core CMS functionality, it includes free SEO tooling centered on a Structured Data Generator that produces valid Schema.org JSON-LD markup without requiring code authorship, a sign-up, or software installation. All data processing occurs locally in the browser, with no data transmitted to external servers except during optional URL-based imports.

The Structured Data Generator supports over 40 Schema.org types spanning articles, products, businesses, events, software, recipes, FAQs, reviews, and more. Users can work in Single output mode for straightforward schema needs or Graph/Multiple output mode for complex linked @graph markup with connected entities. A live JSON-LD preview updates as forms are completed, and field validation catches required-field gaps and common input errors before output is finalized. Existing structured data can be imported from a URL, a saved draft, or pasted JSON-LD directly, with import warnings surfaced for unsupported schema types. Drafts are saved locally in the browser for continuity across sessions.

Contismo targets web publishers, content creators, SEO practitioners, and developers across publishing, SEO, ecommerce, and media industries. The platform's browser-based architecture removes infrastructure and account barriers, making structured data generation accessible to technical and non-technical users alike. Output is copy-paste ready for immediate deployment into any web environment.
