Matecat vs Weblate

Matecat is a free, open-source online computer-assisted translation tool for translators, language service providers, companies, and enterprise teams. It uses translation memories and machine-translation matches to reduce the text translators need to translate, and offers adaptive machine translation from ModernMT in more than 200 languages. The tool supports document and website translation, glossary tools, and real-time teamwork: teams can assign jobs, discuss work in comments, and divide projects among translators. Matecat states that it supports 80 file formats, while the hosted service works with XLIFF out of the box and other formats may require Matecat Filters. REST APIs let users create projects and check their status; API credentials require contacting support with a use description. Its open-source server can be self-hosted. For hosted use, Matecat says browser-to-server communications use SSL, originals and translations are stored long term, and public segments may provide matches to others. It runs in a desktop browser, not on mobile devices. The listed plan is free, with unlimited features, users, and projects.

Weblate is an open-source localization platform for connecting version-control repositories with translation work. New strings can move to translators, and completed translations can return to version control alongside project code. Translation context includes screenshots, nearby strings, source references, shared glossaries, and translation memory. Teams can use customizable quality checks, discussion, and review to catch problems. Machine translation and LLM suggestions are optional; human acceptance and reviewer approval can be required. Weblate supports website and document translation and lists formats such as Android and Apple iOS strings, .NET resources, gettext, JSON, XLIFF, YAML, and WebExtension JSON. Integrations include repositories, an API, add-ons, and import and export tools. It can be deployed using pip or Docker, with guides for OpenShift and Kubernetes. Platforms listed are API, Linux, self-hosted, and web. Self-hosting is free; cloud plans start at €47/mo, and cloud plans include a 14-day trial. Cloud hosting is priced by hosted strings, counting the source language.
