Overview

Localizely is a translation management system for mobile apps, games and websites. It is strongest for teams that want localization work connected to development workflows; teams that require a self-hosted service should look elsewhere.

Its mix of translation tools, file support and developer integrations can bring language work into the same process as software changes. Project and hosted-string limits scale by plan, so the right fit depends on how many projects and strings a team needs to manage.

Key features

Localizely combines AI and machine translation with professional translation orders, translation memory, glossaries, terminology and vendor management. QA checks, screenshots, tasks, reports and branching support review and coordination as well as translation. That breadth can help developers, localization managers and translators coordinate a shared workflow, though smaller projects may have little use for every layer.

File support includes Flutter ARB, Android XML, Apple strings, JSON, YAML, PO, XLIFF, .NET RESX, CSV, Excel and TMX. Integrations with GitHub, GitLab, Bitbucket, Figma and AWS S3, alongside an API and CLI, offer several ways to connect localization with existing tools. GitHub can pull localization files manually or by webhook, then return translations as a pull request—useful for teams that want localization changes reviewed with code.

The Flutter SDK supports over-the-air translation updates and in-context editing. The free plan includes machine and AI translation and translation orders, making it possible to start with more than file management alone. Localizely is SaaS-only, however, so it is not an option for organizations that need to host the service themselves. Its GitHub integration documentation says access tokens are encrypted and are not shown in full after saving.

Pricing

The free plan costs $0.00 USD per free, requires no credit card, and includes one project, 250 hosted string keys, unlimited users and languages, machine and AI translation, and translation orders. It is a useful starting point for a small project, but the 250-key cap makes it a limited long-term home as localization grows.

Paid prices below are per month, billed annually; each plan also has a higher monthly-billing price:

Plan	Annual-billing price	Monthly-billing price	Included capacity
Starter	$16.00 USD per month	$19/mo	500 keys, 1 project, unlimited users and languages; standard features
Advanced	$32.00 USD per month	$39/mo	1,000 keys, 2 projects, unlimited users and languages; standard features
Pro	$65.00 USD per month	$79/mo	2,500 keys, 3 projects, unlimited users and languages; standard features
Bronze	$125.00 USD per month	$150/mo	5,000 keys, 5 projects, unlimited users and languages; advanced features
Silver	$250.00 USD per month	$300/mo	10,000 keys, 10 projects, unlimited users and languages; advanced features
Gold	$475.00 USD per month	$570/mo	20,000 keys, 20 projects, unlimited users and languages; advanced features

Starter is the least expensive paid step for a team that has outgrown the free key allowance but still needs only one project. Advanced and Pro add project and key capacity while retaining standard features. Bronze, Silver and Gold raise both ceilings and include advanced features, for organizations managing a larger portfolio. All listed plans allow unlimited users and languages, so the key and project quotas—not seats—set the stated capacity boundaries. A custom plan has custom pricing for large organizations or customers needing more string keys.

The 15-day trial offers a short evaluation window before a paid commitment. Over-the-air add-ons are priced separately: 30K monthly active users costs $0.00 USD per month, while 200K monthly active users costs $50.00 USD per month. Teams planning Flutter delivery should account for this separate allowance when assessing costs.

Platforms

Localizely is available on the web and supports API access. Its CLI runs on Linux, macOS and Windows and is also available as a Docker image. These options suit teams working across common desktop environments, but deployment remains SaaS-only.

Who it's for

Localizely identifies developers, project and localization managers, and translators as its intended users. It fits teams that need translation work coordinated with code, particularly those using Git integrations or Flutter. The generous user and language allowances across plans suit collaboration, while the capped projects and hosted keys matter more as a team expands. The company says customer care agents are available by email every workday from 7AM to 2AM CET.

Pros and cons

Broad format support: Flutter, Android, Apple, web-oriented and other common localization formats reduce the need to reshape files for different parts of a software stack.
Developer workflow connections: GitHub pull-request delivery, integrations with other code hosts, API and CLI provide routes to fit localization into development work.
Useful collaboration capacity: Paid plans retain unlimited users and languages, avoiding seat or language caps in the stated plan allowances.
Capacity-based cost steps: Hosted keys and project counts are capped, and advancing to higher allowances raises the monthly price substantially.
No self-hosted option: Organizations that require control over deployment cannot choose Localizely.

Alternatives

Weblate is worth comparing when self-hosting matters: it supports self-hosted deployment and offers a Premium Cloud 10k plan at €47 monthly for 10,000 hosted strings with unlimited languages, projects and components.

wxrks (formerly Bureau Works) offers a free plan with annual allowances for words, API calls, AI tokens and machine-translation words. Localazy is another freemium option, with a free plan covering 200 source keys and unlimited seats and languages. locize has a free plan with CDN downloads, word, language, namespace and user limits. OneSky is another freemium alternative. TextUnited offers a free plan with word, PDF-page and user limits. Tolgee has a free plan with a 30,000-word allowance and three seats, plus automation and machine translation.

Verdict

Localizely is a strong fit for software teams that want a capable localization workflow tied to their development stack, especially through Git integrations or Flutter updates. Its broad format coverage and unlimited-user paid plans are compelling; the main reasons to look elsewhere are the hosted-key and project ceilings or the lack of self-hosting.
