Deep Dive: Switching from Crowdin to Mozilla Pontoon
Trade-offs, installation & data architecture
What you trade away
Pontoon is built for Mozilla-style community localization and lacks Crowdin's general-purpose hosted onboarding, integration marketplace, vendor management, automation, and supported deployment.
How to deploy Mozilla Pontoon
Docker setup is documented for development; production deployment must be adapted from Mozilla/Heroku-style infrastructure
What it takes to run
The first obstacle is that the official Docker stack is explicitly not for production and the project does not provide a turnkey supported deployment for arbitrary operators.
Where your data lives
Projects sync translations to version-control repositories, while users, suggestions, reviews, translation memory, and job state live in Pontoon's server databases and caches; Mozilla's public instance is not a general hosted service.
Why fork Mozilla Pontoon instead of vibe-coding a Crowdin clone?
The core loop is buildable, but a dependable replacement becomes a real weekend or multi-day project. For Crowdin, manage a software localization project with file sync, glossary, and reviews. The hard boundary is large integration ecosystem, translators, marketplace, workflows, and enterprise governance, plus translation memory, collaboration, and deployment integrations.
