TechTrade Translate (DeepL) — automatic translation for products, interface & CMS

TechTrade Translate connects your CS-Cart Multi-Vendor store with the DeepL API and translates everything that matters — product listings, all interface texts (language variables), CMS pages, blog posts and menus — into every active language of your store. Translate automatically right after saving, in bulk from the admin lists, or field by field.

Running a marketplace in several languages usually means endless retyping — and, with vendors delivering from different countries, translating from the wrong source language. TechTrade Translate takes that work off your hands and gets the source language right for every single listing.

Key features

• Truly complete: product listings, all interface texts (language variables) AND CMS pages, blog posts & menus — one add-on for a fully multilingual store.
• Per-listing source language: a Dutch vendor is translated from Dutch, an Italian from Italian — detected automatically, ideal for multi-vendor.
• Fully automatic for products: every new or changed listing is queued and translated into all active languages via cron.
• Traffic-light coverage matrix with drill-down: click a red cell, confirm the cost once, watch the progress bar.
• Real DeepL cost control: a price preview before every run, a live cost display matching your DeepL billing period, and a monthly character soft limit as an emergency brake.
• Never pay twice: existing translations are taken over free of charge, unchanged texts are skipped, and manual edits are never overwritten.
• Brand & placeholder protection: brand names and your protect list stay untranslated; [placeholders] and HTML survive every run.
• Timeout-proof: even 20,000+ interface texts run in small steps with a progress bar — no server timeouts.
• Update- & uninstall-proof: API key and settings survive updates and reinstallation; uninstalling never deletes your translations. No license server, no phone-home, no feature freeze.
• DeepL quality, your choice: Free or Pro API, formality preference, classic or quality-optimized model.

Why TechTrade Translate

Most DeepL add-ons translate products from one fixed source language. TechTrade Translate detects the source language for every listing, additionally covers the whole interface and CMS, shows you the real DeepL cost before and across your billing period, protects your manual work — and never locks you in with a license server or a time-limited feature freeze.

Requirements: CS-Cart / Multi-Vendor 4.20+ and your own DeepL API key (Free or Pro).
