Deep Dive: Switching from Transifex to Mozilla Pontoon
Trade-offs, installation & data architecture
What you trade away
Pontoon is not a turnkey small-team service and gives up Transifex's hosted reliability, commercial support, content delivery, integration catalog, and configurable workflows.
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 Transifex clone?
A consolation build is possible, but the paid product's decisive value sits outside a solo rebuild. For Transifex, manage a small software localization project with translation memory and review. The hard boundary is enterprise workflows, integrations, continuous localization, vendors, and support, plus translation memory, collaboration, and deployment integrations.
