Free tool for translating SaaS platforms locale key strings

Dear Product Hunt friends, We are a scaleup who has decided to build our own translation solution (for our locale key strings in our own SaaS platform) so we can easily translate our SaaS into multiple languages. we are considering to offer the solution for free for up to 10.000 strings so other SaaS companies easily can translate their solutions into multiple languages. The reason why we decided to create our own translation software is because we got tired of paying for a tool where we were limited to xxx amonts of locale key strings. So before we get ahead of ourselves i am just writing the topic here for discussion. Is a simple and free translation tool for locale key strings something others could be interested in? I look forward to hearing your thoughts. BR, Martin
