Localize an entire site without touching the source

Building multilingual support from scratch means implementing per-page translation, language switching, URL design, and SEO yourself — a heavy development and operations burden. WOVN.io is a localization layer that sits on top of your existing site: add one line of script and you can start localizing. Translations are applied and updated from the admin console, so you can operate it without touching code.

How it differs from other translation/localization services

Even within "translation," a translation engine that renders text and a service that localizes and operates an entire site play different roles. WOVN.io stands out by layering onto your existing site and taking on translation, language switching, SEO, and operations.

Aspect	WOVN.io	Translation engine (DeepL, etc.)	Localizing it yourself
Target	Entire site / app	Text and documents	Built in-house
Setup	Layer on one line of script	Translate on demand via API/app	Requires development
SEO & operations	Separate URLs, hreflang, admin console	Translation only	Build it yourself

DeepL is a representative translation engine for text itself (DeepL); WOVN.io takes on "site localization and operations" — including that translation. For companies that want to localize an existing site quickly and delegate SEO and ongoing operations, WOVN.io is a strong option.
