What is SimpleLocalize? Localization and Translation Management for your project

In a world where digital products are expected to support multiple languages, SimpleLocalize offers an approachable and efficient way to handle translations. It is not just another localization tool, it is a solution designed to help developers, translators, and product teams manage translations with less hassle and more clarity.

Whether you are building a multilingual website, mobile app, SaaS platform, or desktop tool, SimpleLocalize gives you the tools to manage, edit, and deploy translations, without digging through JSON files or manually syncing language updates.

What is SimpleLocalize?

SimpleLocalize is a translation management platform that focuses on simplicity, clarity, and real-time collaboration. It helps teams manage their localization process more effectively by offering:

• A clean and intuitive translation editor
• Multiple import/export options (JSON, CSV, Excel, YAML, etc.)
• Auto-translation powered by DeepL, Google Translate and OpenAI (ChatGPT)
• Translation hosting through a global CDN
• Role-based access for teams
• Custom translations for individual customers

It's designed to work well for both technical and non-technical users, making it a great choice whether you are a developer, translator, or project manager.

How translation management works in SimpleLocalize

Instead of editing files manually or relying on outdated spreadsheets, SimpleLocalize gives you a structured process to follow. Here is how it works:

1. Import translations

Start by uploading your existing translation files. You can use files in formats like JSON, CSV, Excel, or YAML. Prefer automation? Use our REST API or open-source CLI tool to integrate SimpleLocalize into your development workflow.

2. Translate in a user-friendly editor

Once your keys are imported, you can begin translating using SimpleLocalize's online editor. It offers two customizable views:

• Table View: A spreadsheet-style layout perfect for translators. It's easy to scan, edit, and filter translations.
• List View: Great for longer texts and metadata management. You can view a translation key’s description, associated namespace, and history.

You can also enable useful translation hints like character counts, word summaries, and see which strings were translated using auto-translate.

3. Download or host your translations

After your translations are complete, you can download them in your preferred format or take advantage of SimpleLocalize's translation hosting. Hosting allows you to deliver up-to-date translations via a CDN, so you don't need to redeploy your app every time a translation changes.

Key features that make a difference
