Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Microsoft Translator
- Published free-tier detail is thinner than Google’s or Amazon’s clearly stated character allowances, making it harder to estimate cost from public documentation alone.
- Translation quality for major language pairs is broadly comparable to Google Translate and Amazon Translate, so there is little functional differentiation beyond price and Azure ecosystem convenience.
- Commitment-tier discounts require a negotiated minimum spend, so smaller developers without predictable volume do not get Microsoft’s most competitive published rate.
- Custom Translator model training and management add operational complexity beyond simple API calls, requiring parallel training data the buyer must supply and maintain.
- Adopting it while already using a different primary cloud (AWS or Google Cloud) means managing a second cloud billing relationship purely for translation, which is administratively unappealing for some teams.
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.
