Altified vs Weglot: SDK localization or website translation?
A practical comparison of hosting, dynamic content, SDK integration, SEO URLs, and ownership for teams choosing a localization architecture.
/ The short answer
The central difference is where the localized experience is assembled. Weglot specializes in translating and delivering websites through its integration model. Altified puts the localization workflow inside the application so your own frontend and backend remain responsible for pages, records, APIs, and search signals.
| Capability | Altified | Weglot |
|---|---|---|
| Hosting | Localized responses are rendered and deployed by your application and infrastructure. | Supported website integrations can route translated language versions through Weglot's delivery layer. |
| Dynamic/database content | Use stable keys for database, CMS, and API-backed values; Django fields can be localized through the SDK. | Translates detected website content and supports dynamic web experiences through its integrations, but the source application's data model remains separate. |
| SDK integration | First-party Next.js and Django integrations connect routing, server rendering, backend locale propagation, and translation resolution. | Uses website integrations, plugins, snippets, and proxy options across a wide set of platforms. |
| SEO URLs | Your routing model decides between paths such as /fr/products/25, subdomains, or another application-owned structure. | Supports SEO-friendly subdirectories and subdomains, with URL and metadata handling managed through the integration. |
| Ownership | Keep code, data access, credentials, release decisions, and localized page rendering in your stack. | Keep the source website while using Weglot as the translation and delivery system for language versions. |
| Best fit | Products with authenticated workflows, APIs, dynamic records, and application-specific SEO requirements. | Websites that value quick setup, broad platform support, and managed translation operations. |
The right choice depends on where your content lives, how it is delivered, and how much control your team needs over the localized experience.
/ What this means for your stack
Choose the delivery model before choosing the translation workflow.
For a marketing site, both architectures can produce crawlable language URLs. The decision becomes more consequential when the localized page is assembled from authenticated data, application APIs, or records that change after deployment.
Altified keeps the boundary between your application and the translation workflow explicit. That makes it easier to reason about permissions, caching, route ownership, and source changes in one engineering system.
/ Where Altified fits
Keep translation connected to the application that serves it.
Altified is the better fit when localized pages need to be rendered by your own frontend and backend, with dynamic records, application routes, and search metadata in the same delivery model.
/ Frequently asked questions
Questions teams ask before choosing a localization stack.
Does Weglot use a translation proxy?
Weglot documents multiple integration modes, including server-side subdirectory and subdomain delivery through its translation infrastructure. The exact architecture depends on the integration.
Which product gives developers more control over application routes?
Altified is designed for the application to own locale routing and page rendering. Weglot provides managed language URL options through its website integration model.
Can Altified translate database content?
Yes. The Next.js SDK supports explicit dynamic values and the Django SDK can localize configured model fields with stable keys.
