The short version

  • Only Pontoon has a free tier, so it costs nothing to try first.
  • Each has a real cost: Plunet pricing is never published and licensing is per user, so a growing agency faces a recurring negotiation each time it adds project managers.; 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: Plunet covers CAT tool connectors, 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.

Plunet

  • Pricing is never published and licensing is per user, so a growing agency faces a recurring negotiation each time it adds project managers.
  • Configuration to match an agency real workflow is substantial, and firms report months of setup before the system reflects how they actually work.
  • It manages the business layer only; you still need and pay for separate CAT tools, so total software spend is higher than the Plunet quote alone suggests.
  • The interface is dense and built for full-time project managers, which makes it a poor fit for occasional users or very small teams.
  • Reporting and dashboards are functional rather than modern, and firms wanting BI-grade analytics typically export data to a separate tool.

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.
