What it is

A self-hosted localisation platform — the open-source answer to Crowdin, Lokalise and Phrase. Every user-facing string lives in one server, SDKs for React and a dozen other frameworks pull them at build or run time, and its distinguishing trick is in-context editing: you alt-click a piece of text in your running app and correct the translation right there.

What it is good for. A bilingual maker can write the copy, record the tutorial and answer the support email in two languages. What is usually missing is a way to keep two versions of an interface in step. Maintaining two JSON files by hand is precisely the job that gets abandoned in week three, and a half-translated interface is worse than a monolingual one. Tolgee turns the second language from a code problem into a data problem: adding Russian to a new screen becomes a translation someone types, not a release someone ships. And the in-context editing matters more on a one-person project than in a team, because the translator is the person looking at the screen — being able to fix an awkward Russian phrase while looking at the actual button is the difference between doing it and meaning to.
