Solo dev releases translation API: 60k chars/request, auto language detection
A developer built and released their own translation API using an open-source model called TranslateGemma. It handles up to 60,000 characters per request and automatically detects the input language. It's a practical option for solo builders who want to add translation to their product without paying for Google Translate or DeepL.
Instead of relying on paid translation services like Google Translate or DeepL, this developer used TranslateGemma — an open-source translation model — to build a self-contained translation API. The standout features are a generous 60,000-character limit per request (roughly 40–50 pages of text) and automatic language detection, so callers don't need to specify the source language.
For solo operators running web or app products, this is worth noting as a potential cost-saving alternative to commercial translation APIs. The API is already live and available to connect to, lowering the barrier to adding multilingual support to a small product.
