# Build vs Buy: Localization Infrastructure

Building makes sense for one narrow task and stops the moment orchestration is involved. Where that line sits, and what a build actually commits you to.

> **Quick answer —** Build when the need is one narrow, stable task you can specify completely. Buy when the requirement is orchestration across content types, because the cost is in the workflow layer rather than in any single translation call.[Vitra.ai Universe](https://www.vitra.ai/platform) creates, translates, adapts and publishes from one place.

## The line is narrowness, not size

Plenty of teams should build. If the requirement is one atomic job — translate these strings, on this trigger, into these four languages, with no review step — that is a weekend of work against an API and it will run for years.

The line is crossed when the answer to "and then what" keeps going. Then it needs review. Then images. Then the video. Then a second brand with different terminology. Each of those is reasonable on its own and none of them is the thing you set out to build.

## What building actually commits you to

Layer

Looks like

Turns out to be

Translation calls

An API

Genuinely easy

Format handling

A library

One per format, forever

Memory

A database

Matching, cascade, write-back

Review

A queue

Roles, notifications, audit

Orchestration

A job runner

Retries, partial failure, ordering

Quality

A checker

The hardest part, and never finished

Multimodal

Later

A second system

Only the first row is the thing anyone estimates. The rest is the product, and it does not stop being built — models change, formats change, a market asks for something.

## Orchestration is where buying wins

A single translation call has no interesting failure modes. A run that creates an asset, translates it into forty languages, adapts each into ten placements, gates two of them for review and publishes the rest has a great many.

Partial failure, ordering, retries that must not duplicate work, a reviewer who is on leave — that is [workflow](https://www.vitra.ai/features/agentic-workflows) engineering, and it is the part that takes a team a year and is invisible in a business case.

Scale makes it worse rather than better, because the failure modes are combinatorial across content types.

## The honest test

Ask what happens when the person who built it leaves.

A narrow script survives that. A [half-built platform](https://www.vitra.ai/general/why-localization-projects-fail) does not, and the usual outcome is a system nobody will change, working around it rather than through it.

Buy where the requirement is breadth — [memory](https://www.vitra.ai/features/translation-memory) across every modality, [quality control](https://www.vitra.ai/features/quality-control) that returns findings, an [asset manager](https://www.vitra.ai/features/asset-manager) holding the output — and build the one narrow connector that is genuinely specific to you.

That combination is almost always right, and it is rarely the way the question gets framed.

## FAQ

**When does building a localization system make sense?** When the requirement is one narrow, stable task you can fully specify — translate these strings on this trigger into these languages, with no review step. That is a small build that runs for years.

**What gets underestimated in a build?** Everything after the translation call. Format handling, memory matching and write-back, review roles and audit, orchestration with partial failure and retries, and quality checking, which is never finished.

**Why is orchestration the argument for buying?** Because a single translation call has no interesting failure modes, while a run spanning creation, forty languages, ten placements and two review gates has many, and they compound across content types.

**What is the practical test for build versus buy?** Ask what happens when the person who built it leaves. A narrow script survives that; a half-built platform becomes a system nobody will change, and teams work around it rather than through it.
