Deep Dive: Switching from Phrase to Mozilla Pontoon
Trade-offs, installation & data architecture
What you trade away

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

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 Phrase clone?
A consolation build is possible, but the paid product's decisive value sits outside a solo rebuild. For Phrase, manage a modest string catalog with review and CI sync. The hard boundary is enterprise translation management, automation, integrations, analytics, and global operations, plus translation memory, collaboration, and deployment integrations.
