Automated i18n for existing codebases: AST-based string extraction, build-time auto-wrap, ICU plural runtime, and LLM translation. Absolutely no hand-written `t()` calls required.

Our flagship benchmark measures Hedgeling end-to-end on seven real-world open-source projects — and a separate head-to-head run compares it against i18next-cli. The result is focused string extraction that saves hours of manual cleanup. ### Starting Fresh Migration Precision Across 6 migration projects, Hedgeling surfaced 19,952 strings from 824,721 lines of code. Sampled precision landed in the 82%-100% range. High sampled project100% 100% Precision Low sampled project82% 82% Precision ### Auditing Existing Apps Gap Detection On already-internationalized apps, the benchmark estimates 184 missed hardcoded UI strings. The useful metric is true-gap rate, because every real finding is a localization gap. Keycloak70% 70% True-gap rate Directus83% 83% True-gap rate ### Don't just take our word for it. Dive into the exact methodology, raw result data, and configuration files behind every number — from the 1125k-LOC flagship suite to the 11.8M-LOC, 56-repo mega run and the i18next-cli head-to-head.

You control the quality. Hedgeling is a technology provider, not a translation agency. We don't offer a blanket "quality guarantee" because true localization quality is highly subjective and belongs in your hands. We give you a flexible platform to configure your flow exactly how you like - use some features, or use them all. ### Zero-Touch Extraction Stop polluting your clean code with translation wrappers. We extract user-facing strings directly from source and auto-wrap them at build time. Content your app fetches from APIs and databases at runtime is covered too. ### Context Engine Our engine automatically extracts code context, calculates strict character limits, and validates UI placeholders. ### Brand Voice Control Enforce your specific tone across languages with custom personas, style guides, and glossaries integrated directly into the LLM pipeline. ## Built for the entire pipeline ### For Developers From SaaS vibecoders to game developers, focus on your code, not your string catalog. Run our CLI tool to scan your project, flag diagnostics, and export to native resources like `.resx`, `.po`, CSV, or JSON. ### For Localization Managers Maintain absolute control over the brand. Build comprehensive style guides, set up character limits for tight UIs, and review AI outputs without vendor lock-in. You configure the flow, we provide the engine. ### For Translators Eliminate the guesswork. Work within an interface that provides clear descriptive context (button, label, link) and use our industry-first **in-tool AI directives**. Instruct the LLM directly to "make it shorter" or "sound friendlier" without leaving the CAT tool. ## Pricing Start free with no card, then pick the plan that matches your string count and locales.
