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.; Sonix monthly hour allowances are small relative to the subscription price: the $25 Core plan includes five hours, which at the published $10 overage rate means the subscription is only worth buying for storage and features rather than for the hours.
  • They diverge on capability: Localazy covers Per source key pricing, Sonix covers Automated transcription.
  • Prices and features above were last checked on 31 August 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 Sonix
  • An indie developer or small studio that needs a genuinely free tier rather than a fourteen day trialnot Sonix
  • Teams that want strings pulled from Figma so copy is localised before the interface is built rather than afternot Sonix
  • Continuous localisation in a build pipeline through the CLI and GitHub Actions, with runtime delivery through the CDNnot Sonix

Sonix

  • A journalist transcribing interviews in several languages who needs the transcript searchable and quotable within minutes rather than accurate to a contractnot Localazy
  • A qualitative research team coding focus group transcripts, where speaker separation and an editable transcript matter more than a certified accuracy figurenot Localazy
  • A podcast producer generating subtitle files and show notes from each episode without adding a human transcription suppliernot Localazy
  • A small documentary team subtitling foreign-language footage where transcription and translation in one tool avoids a second vendornot 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.

Sonix

  • Monthly hour allowances are small relative to the subscription price: the $25 Core plan includes five hours, which at the published $10 overage rate means the subscription is only worth buying for storage and features rather than for the hours.
  • Unused hours do not accumulate into a meaningful reserve, so an irregular workload of a heavy month followed by a quiet one pays overage in the first and wastes allowance in the second.
  • There is no human correction tier at self-service prices, so anyone with an accessibility or legal accuracy obligation has to add a separate supplier or a member of staff to the workflow.
  • The cited 99 percent accuracy is a best-case figure on clean single-speaker audio, and overlapping speakers, strong accents, technical vocabulary and room noise degrade it enough that editing time, not transcription cost, becomes the real expense.
  • Storage is capped per plan at 25GB to 100GB, and video files consume it fast, so long-running teams end up deleting source media or upgrading a tier for storage they do not otherwise need.

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.

Sonix: What does Sonix cost per hour?

$10 an hour on pay-as-you-go, and $10 an hour for any usage beyond the monthly allowance on every subscription tier. That overage rate is published, which is unusual in this market.

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.

Sonix: Is there human transcription?

No. Sonix is automated transcription plus an editor for you to correct. If you need a contracted accuracy level, this is the wrong category of product.

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.

Sonix: How accurate is it really?

The 99 percent claim assumes clean, single-speaker, standard-accent audio. Multi-speaker recordings with background noise land noticeably lower, and the cost shows up as your editing time.

Localazy: Can I get single sign-on?

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

Sonix: How many languages?

Transcription in over fifty languages and translation into a similar number, which is wider than most self-service competitors.
