Cost
$0 / forever (Open Source)
License
BSD-3-Clause
Hosting Model
Self-host (your server)
Platforms
webself-hostedself-host, real ops
Installation
Docker setup is documented for development; production deployment must be adapted from Mozilla/Heroku-style infrastructure
Operational Setup
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.
The Catch / Trade-off
Pontoon is built for Mozilla-style community localization and lacks Crowdin's general-purpose hosted onboarding, integration marketplace, vendor management, automation, and supported deployment.
