The short version

  • Each has a real cost: Amazon Translate the generous 2 million character monthly free tier applies only for a customer’s first 12 months on AWS, so translation costs step up materially in year two with no change in usage.; 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: Amazon Translate covers Text translation API, 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.

Amazon Translate

  • The generous 2 million character monthly free tier applies only for a customer’s first 12 months on AWS, so translation costs step up materially in year two with no change in usage.
  • There is no consumer-facing app or website, so it is unusable for casual personal translation the way Google Translate or Microsoft Translator are.
  • Document translation of Office files costs double the standard per-character rate, which is easy to underestimate when budgeting a document-heavy project.
  • Active Custom Translation, the tool for improving output with domain-specific data, costs four times the standard rate at $60 per million characters.
  • As with all major MT APIs, output for low-resource languages and specialised terminology often still needs human review, so it does not substitute for a human translation service on customer-facing or legally sensitive content.

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.

Answered from the vendors’ own pages

Amazon Translate: How generous is the free tier really?

2 million characters per month, the largest of the three major cloud APIs, but only for the first 12 months after which standard per-character pricing applies to everything.

Pontoon: Is there a paid hosted version?

No. Mozilla runs an instance for its own projects. Anyone else deploys their own.

Amazon Translate: Is there a consumer app like Google Translate?

No, Amazon Translate is a developer API only, accessed through the AWS console and SDKs, with no separate public-facing app.

Pontoon: What does it actually cost?

Server hosting, engineering time to operate it, and whatever machine translation engine you connect. There is no licence fee.

Amazon Translate: How much does document translation cost compared to text?

Double the standard rate, at $30 per million characters for Office file formats.

Pontoon: Is it suitable for a commercial product?

Only if you have infrastructure staff and mostly software string formats. Document translation and vendor support are missing.
