The short version

Each has a real cost: OmegaT there is no commercial support contract available, so a business relying on it for critical work has only community forums to fall back on when something breaks.; POEditor the quota counts every string on the account, including obsolete terms from retired features, so cost creeps upward unless someone deliberately prunes projects.
They diverge on capability: OmegaT covers Glossary support, POEditor covers String based billing.

Where each one falls short

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

OmegaT

There is no commercial support contract available, so a business relying on it for critical work has only community forums to fall back on when something breaks.
It lacks the cloud-hosted, real-time collaborative project management features of commercial TMS platforms like memoQ or Smartling.
The interface is a Java desktop application with a dated look and feel compared with modern web-based CAT tools, which affects onboarding speed for new users.
Release cadence and feature development depend on volunteer contributor availability rather than a company roadmap, so some requested features take a long time to arrive, if ever.
Machine translation integration requires configuring third-party API keys (Google, DeepL) separately, adding setup steps a commercial all-in-one tool would handle natively.

POEditor

The quota counts every string on the account, including obsolete terms from retired features, so cost creeps upward unless someone deliberately prunes projects.
Several projects share one account quota, so a team can be pushed into a higher tier by work in an unrelated repository.
There is no in-context or visual editor, so translators guess at where a string appears and length or gender errors surface only after a build.
Quality assurance checks are basic compared with the larger platforms, with no configurable rule sets or enforced terminology gates.
The company is small, support is email based, and there is no self-hosted or on-premises option, which rules it out where data residency is contractually fixed.

Answered from the vendors’ own pages

OmegaT: Is OmegaT really free, with no paid version?

Yes, it is fully free and open source under the GPLv3, with no commercial edition or vendor support contract sold alongside it.

POEditor: Does it charge per translator?

No. Contributors and languages are unlimited on every plan. Only the total string count is billed.

OmegaT: Who maintains OmegaT?

A volunteer open source community, not a company; this differs from MateCat, which is developed and hosted by the company Translated.

POEditor: Is there a free plan for open source?

Yes, open source projects can apply for a free plan, which is why many community translated applications use it.

OmegaT: Can it open files from Trados or Wordfast?

Yes, via the bundled Okapi Filters plugin, which supports SDLXLIFF, TTX, TXML and many other commercial CAT tool formats.

POEditor: Does it support in-context translation?

No. Translators work from the string list and any comments or screenshots you attach, not from a live preview.
