Dedicated Localization Instance for Enterprise Teams

Public SaaS is perfect for getting started. At enterprise scale, though, sending your product's unreleased source strings to a shared service is often a non-starter — for security, compliance, or data-residency reasons. l10n.dev for Enterprise gives you the exact same AI localization engine as a private, single-tenant instance that we deploy and operate for you: in the cloud region you require, on your own isolated subdomain (for example yourcompany.l10n.dev), with the database living inside your own infrastructure. You get enterprise-grade control, security, and format guarantees — without standing up a localization team or building and maintaining an in-house pipeline.

Fully managed, fully isolated

It's your own instance, not a shared tenant. We handle deployment, upgrades, monitoring, and scaling, so your engineers stay focused on the product while localization simply works in the background.

• Dedicated single-tenant deployment on your own subdomain — no shared database, storage, or translation balance with any other customer.
• Runs in the cloud region you choose, so performance and data residency match your requirements.
• We operate and maintain it end to end — you get a running, supported service, not another system to babysit.

Your data never leaves your boundary

Source strings and upcoming release copy are some of your most sensitive pre-launch assets. With a dedicated instance, they stay inside infrastructure you already control and trust.

• The database can live in your own data center or private cloud — your data, your governance, your backups.
• Nothing is copied into the shared multi-tenant platform, so unreleased features and product plans stay confidential.
• Built to pass internal security reviews and satisfy data-residency, GDPR, and audit requirements.

Bring your own AI model — under your controls

Connect the LLM your organization already approves, using your own keys, so every translation request stays within the model governance and contracts you've already signed off on. This is a security and compliance decision first, not just a technical one.

• Use your own LLM provider and API keys, under your existing contracts, data-processing terms, and security controls.
• Your content flows only to the provider you approve — never to shared or default models, and never used for training.
• We help you select and validate the right model for your full language set, rare languages included.

Guaranteed format safety — because we build the checks for you

The real risk with AI localization isn't an awkward phrase you can edit later — it's a malformed file silently breaking a production build or shipping a broken screen to millions of users. We remove that risk by building programmatic validation tailored to your exact i18n format, so every translation is double-checked against your rules before it's delivered. That's what lets us guarantee it.

• We customize the format double-check logic for your specific files (JSON/JSONC, ARB, YAML, PO, XLIFF, RESX, and more) — not a generic, one-size-fits-all validator.
• Keys, placeholders, ICU plurals, HTML tags, and structure are verified on every string; anything that would break your build is caught, not shipped.
• Change detection and incremental translation run inside your instance, so only modified strings are re-translated — protecting approved translations and cutting cost.

Cheaper than building or staffing it yourself

Enterprise localization usually means one of two expensive paths: hiring dedicated localization engineers and translators, or building and maintaining an in-house AI translation pipeline. A dedicated instance replaces both with a single, predictable line item — and frees your team to ship faster in more markets.

• Flat, volume-based pricing with no per-character metering — so you can budget with confidence even as translation volume grows.
• Typically costs less than the fully-loaded salary of a single localization engineer, and removes the ongoing burden of building and maintaining your own tooling.
• Plugs into your existing CI/CD and localization workflows, so teams adopt it without re-architecting how they release.

Secure by design

Every layer is built to keep your content, credentials, and infrastructure firmly under your control.

• Single-tenant isolation — no shared data, storage, or compute with other customers.
• Data residency in your chosen region, with the database in your own environment.
• Your LLM keys and provider governance; your content is never used to train shared models.
