checklist

Please make sure you've complied with the contribution guidelines:

• The homepage clearly states that the product is for developers.

  "Headless", "API-First", "SaaS" are frequently used keywords.
  Usually this means that the front page has some code examples :)

• The product is available now and requires payment.
• The PR has a descriptive title -- e.g., Add {Product}, not Update README.md.
• The new submission isn't a duplicate.
• The entry has a description, is sorted alphabetically, and ends with a full stop.

Thanks!

Disclaimer: I am not associated with the Locize in any way. I have used this product in two large enterprise projects have found incredibly useful as a development tool.
