  • Each has a real cost: Localazy the price ladder is stepped rather than continuous, so a project that grows from 2,500 to 2,600 source keys jumps a whole bracket rather than paying slightly more.; 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: Localazy covers Per source key pricing, Pontoon covers Repository sync.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

Where each one falls short

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

Localazy

  • The price ladder is stepped rather than continuous, so a project that grows from 2,500 to 2,600 source keys jumps a whole bracket rather than paying slightly more.
  • Single sign-on, audit logs, an SLA, priority support and audit trails are all Enterprise-only, and Enterprise is the one tier with no published price, so the moment a security review lands you leave the transparent pricing behind.
  • Counting by source key penalises content models where every paragraph is a separate key, so a documentation site or a marketing site can consume brackets far faster than an application with the same amount of text.
  • Human translation is sold in the platform but its rates only become visible after you have signed up, and whether Localazy takes a margin on that work is not disclosed anywhere public.
  • It is a company of roughly twenty people with no disclosed investors and no published legal entity details, which is a real continuity question for anyone putting a multi-year product localisation pipeline through it.

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

Localazy: What exactly is a source key?

One segment of text in your source language, such as a button label or a short paragraph. The same key translated into ten languages still counts as one key, and languages are unlimited on every plan.

Pontoon: Is there a paid hosted version?

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

Localazy: Is the free plan a trial?

No, the 200 key free plan is permanent and includes unlimited seats and languages. Separately, new signups get a fourteen day trial of the Business plan.

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.

Localazy: How does it compare with per-word pricing?

It stops scaling with locale count. If you ship in three languages the difference is small; if you ship in thirty, per-key pricing is structurally cheaper rather than marginally so.

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.

Localazy: Can I get single sign-on?

Only on Enterprise, which is quoted rather than published. There is no mid-tier SSO option.
