Configurable localization engines
Create a stateful localization engine that keeps glossary terms, brand voice, instructions, and model selection attached to every translation request.
Lingo.dev
BeanspruchenLingo.dev is a localization engineering platform that turns LLMs into stateful translation APIs for apps, docs, and workflows via code, CLI, CI/CD, and MCP.
Overview
Lingo.dev is a localization engineering platform for teams that want to treat translation as part of their product and delivery workflow. It turns LLMs into stateful translation APIs that keep glossary rules, brand voice, locale-specific instructions, and model choices attached to each request.
The platform is built for apps, docs, and other content that must stay consistent across languages. Teams can call localization engines from code, the CLI, CI/CD, or MCP, and the documentation describes both synchronous translation and background jobs for multi-locale work. The pricing page shows sandbox, production, and enterprise options, with platform access included on every tier.
Features
Synchronous and asynchronous translation
Use the API for programmatic translation, with one-request delivery for a single locale or asynchronous jobs for multi-locale workloads.
Per-locale model selection and fallback
Apply per-locale model chains with ranked fallback so translation can continue when a preferred provider is unavailable.
Persistent localization context
Set glossary rules, brand voice, and locale-specific instructions so terminology, tone, and formatting stay consistent across releases.
Quality scoring and review
Add quality checks such as AI review, glossary compliance, and locale-specific validation to inspect translation output over time.
Developer workflow integrations
Connect localization to development workflows through the CLI, CI/CD integrations, and MCP support for coding assistants.
Use Cases
Product localization with stable terminology
Configure a localization engine for a product so terminology, tone, and locale rules persist across releases instead of being re-decided in each translation request.
Programmatic translation in an app
Translate content from application code or backend services when you need the translation result returned directly from an API call.
Batch translation for multi-locale releases
Send locale work as background jobs when you need many translations at once and want the app to stay responsive while processing continues.
Localization in development pipelines
Run translations as part of build and delivery workflows so localized content moves with the codebase through CLI or CI/CD automation.
Quality-controlled localization review
Use the platform’s context and quality checks to review glossary adherence, tone, and other quality dimensions before delivery.
Pros and Cons
Pros
- Keeps glossary, brand voice, instructions, and model selection persistent across translation requests.
- Supports both direct API calls and asynchronous background jobs.
- Fits multiple developer workflows, including CLI, CI/CD, and MCP.
- Includes quality scoring and review steps, not just raw translation output.
- Shows a pricing structure with sandbox, production, and enterprise paths.
Cons
- The source does not provide detailed public limits for all tiers or workflows.
- Some integration and use-case coverage is documented only partially in the provided sources.
FAQ
What is Lingo.dev?
The source describes Lingo.dev as a localization engineering platform that helps teams turn LLMs into stateful translation APIs. Teams configure a localization engine once, then use it from code, the CLI, CI/CD, or MCP.
How does the API handle different translation workflows?
The documentation says the API is for programmatic translation. You can send a single request for one locale and read the result immediately, or send many locales as background jobs while your app stays responsive.
What can teams configure in a localization engine?
The docs describe localization engines as combining LLM models per locale, brand voice, glossary rules, instructions, and quality scoring. The platform also mentions developer tools such as the CLI, CI/CD integrations, and i18n MCP for coding assistants.
Does Lingo.dev have paid plans?
The pricing page shows a sandbox plan, a production plan, and an enterprise option. It also states that LLM costs are passed through at zero markup and that platform access is included on every tier.
