Deep Dive: Switching from Lokalise to Mozilla Pontoon
Trade-offs, installation & data architecture
What you trade away
Pontoon lacks Lokalise's turnkey hosted onboarding, broad CI/design/mobile integrations, branch management, commercial support, and supported general-purpose 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 Lokalise clone?
The core loop is buildable, but a dependable replacement becomes a real weekend or multi-day project. For Lokalise, manage translation keys, screenshots, reviews, and CI sync for a small product team. The hard boundary is integration breadth, translation memory, workflows, vendors, governance, and support, plus translation memory, collaboration, and deployment integrations.
