Localess is an open-source headless CMS and translation management platform created by Lessify, released under the MIT license and built on Angular with a Firebase/Google Cloud backend. It combines structured content modeling and multi-locale publishing with a dedicated translation workflow, including translation memory and terminology consistency checks.
Because it deploys into a user's own Firebase project rather than running as multi-tenant SaaS, Localess bills itself as free forever, with the only ongoing cost being the underlying Firebase/GCP infrastructure usage.
Content teams can visually define schemas without code, publish simultaneously across 30-plus languages from a single editor, and see changes go live instantly without rebuilding the consuming application.
Translation-specific features include translator assignment, review and approval workflows, translation memory to reuse prior translations, terminology consistency checks, and AI-assisted translation via Google Translate, alongside a digital asset library with localization-aware asset attachment.
Localess itself is free and open source under the MIT license, with no license fees.
