The short version

  • Each has a real cost: Google Translate the free consumer app and the metered developer API are commercially separate products despite sharing branding, which confuses buyers evaluating cost for an integration project.; Pontoon there is no hosted commercial edition, so adopting it means running Django, PostgreSQL and a task queue yourself and keeping them patched.
  • They diverge on capability: Google Translate covers Text translation, Pontoon covers Repository sync.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Google Translate

  • The free consumer app and the metered developer API are commercially separate products despite sharing branding, which confuses buyers evaluating cost for an integration project.
  • API costs scale linearly with content volume, so a high-traffic application can accumulate significant monthly spend even at $20 per million characters.
  • Custom model training pricing starts as high as $80 per million characters at low volumes, a steep premium over the standard NMT rate for domain adaptation.
  • Machine translation output for low-resource language pairs or specialised terminology often still needs human post-editing, so the API alone does not replace professional translation for anything customer-facing at high stakes.
  • There is no bundled human-in-the-loop quality tier; a business needing verified accuracy has to pair the API with a separate service such as Unbabel or Gengo.

Pontoon

  • There is no hosted commercial edition, so adopting it means running Django, PostgreSQL and a task queue yourself and keeping them patched.
  • No vendor support and no service level agreement exist, so an outage during a release freeze is your engineering problem alone.
  • The roadmap serves Mozilla localisation needs first, and features outside that scope are unlikely to be built for you.
  • Format coverage is narrow next to commercial systems: it is strong on PO and Fluent, weak on document formats such as InDesign or complex XML.
  • Because you host it, security and compliance evidence such as an external audit report does not exist, so any assurance your customers need has to be produced by your own team.
