The short version

  • Only Localazy has a free tier, so it costs nothing to try first.
  • 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.; 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: Localazy covers Per source key pricing, Systran covers Systran Translate Pro.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Localazy

  • A mobile or web application that ships in twenty or more locales, where per-word pricing would multiply the bill by every added marketnot Systran
  • An indie developer or small studio that needs a genuinely free tier rather than a fourteen day trialnot Systran
  • Teams that want strings pulled from Figma so copy is localised before the interface is built rather than afternot Systran
  • Continuous localisation in a build pipeline through the CLI and GitHub Actions, with runtime delivery through the CDNnot Systran

Systran

  • A government or defence agency needing machine translation that never leaves its own network, which rules out cloud-only APIsnot Localazy
  • A legal or financial services firm with confidentiality requirements that installs Systran Enterprise on-premisesnot Localazy
  • A localisation team wanting native CAT tool and TMS connectors rather than building raw API integration themselvesnot Localazy
  • A small team of translators using Translate Pro’s per-seat web plans for interactive, human-facing translation work rather than bulk automated contentnot Localazy

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.

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

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.

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.

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.

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.

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.

Systran: Who owns Systran now?

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

Localazy: Can I get single sign-on?

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