What it is
SimpleLocalize helps teams manage software translations and localization workflows. Its web editor includes customizable views, collaboration tools, and word and character counters, while AI and machine translation and no-code automations can support translation work. Projects can host translations behind a CDN for delivery to users and developers. Developers can use a REST API and an open-source CLI that runs on Windows, macOS, and Linux. The CLI supports more than 30 localization formats, including JSON, YAML, XLIFF, PO, ARB, Android XML, iOS Strings, CSV, and Excel. Listed integrations include GitHub, Figma, VS Code, IntelliJ, Shopify, Webflow, DeepL, and OpenAI. Users can import Excel or CSV and export to Excel, CSV, or JSON. The free Community plan costs nothing and includes 500 translation keys, unlimited strings, 10 projects, 10 languages, one team member, and 90-day activity and history. A 14-day trial is also listed. All plans follow a Fair Use Policy; custom plans are available for large teams and enterprises.
