As answered by people managing Apache Solr and structrans.
structrans's answer:
structrans uses syntax-aware and layout-aware AST parsing. Instead of treating files as raw text, it extracts only human-readable strings, translating copy via LLMs while preserving 100% of document margins, tables, and code variables ({user}, %s, {{id}}).
structrans's answer:
Unlike generic translators (Google Translate, DeepL) that distort document formatting and break code variables, or enterprise TMS platforms (Lokalise, Crowdin) that cost 100–500$/mo and require complex setup, structrans offers instant, zero-friction web translation with zero layout corruption and a free tier.
structrans's answer:
Content managers translating corporate Word (DOCX) and PDF documents, software developers localizing app i18n files (.json, .po, .arb, .xliff), and marketing teams needing fast, layout-preserved document translation.
structrans's answer:
We got frustrated after repeatedly seeing standard web translators destroy Word document tables and break template variables during software release cycles. We built structrans to give developers and content managers a simple, privacy-first tool that translates files cleanly without ruining code or layout.
structrans's answer:
Built on Cloudflare Workers edge runtime, Astro, React, and powered by high-accuracy LLM translation engines combined with custom document AST parsers and LibreOffice/Tesseract OCR layout processing.
structrans's answer:
structrans is primarily used by indie software developers, digital marketing agencies, content managers, and remote international startup teams translating i18n locale files and business documents across 20+ languages.
