The short version

Only Pontoon has a free tier, so it costs nothing to try first.
Each has a real cost: Pontoon there is no hosted commercial edition, so adopting it means running Django, PostgreSQL and a task queue yourself and keeping them patched.; Systran per-seat web pricing at $25.99 to $49.99 a user per month is far more expensive than the raw per-character cost of Google, Microsoft or Amazon’s APIs for high-volume, low-touch use cases.
They diverge on capability: Pontoon covers Repository sync, Systran covers Systran Translate Pro.

Where each one falls short

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

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.

Systran

Per-seat web pricing at $25.99 to $49.99 a user per month is far more expensive than the raw per-character cost of Google, Microsoft or Amazon’s APIs for high-volume, low-touch use cases.
On-premises Enterprise deployment requires infrastructure and IT resourcing that a simple cloud API call does not, adding real implementation cost and time.
Enterprise and Systran.io pricing is not published, so budgeting for that tier requires a sales quote before any real comparison is possible.
Its market share and brand recognition are smaller than Google, Microsoft or Amazon, so integration examples, community support and third-party tooling are less abundant.
Translation quality for common language pairs is broadly comparable to the major cloud APIs, so the main reason to pay a premium is data residency, not superior output.

Answered from the vendors’ own pages

Pontoon: Is there a paid hosted version?

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

Systran: Why would I pay more for Systran than Google’s API?

Primarily for on-premises deployment, where translation never leaves your own network, which matters for government, defence or confidentiality-bound organisations.

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.

Systran: Is Systran priced per character like Google or Amazon?

The Translate Pro web plans are priced per user per month; only the Enterprise and Systran.io API products are usage-based, and their pricing is quoted rather than published.

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.

Systran: Who owns Systran now?

It operates as part of ChapsVision, a French technology group, following a series of ownership changes.
