Weblate

Overview

Weblate is an open-source localization platform that links repositories to translation workflows. It is best suited to software teams that want translators working with project context and review, with the choice to manage hosting themselves or pay for cloud service. Its repository-centered approach is a strong fit for ongoing product localization, but less so for translation work unrelated to software development.

Key features

Weblate sends new strings to translators and returns completed translations to version control alongside project code. That keeps localization close to development instead of relying on a separate file handoff. It supports website and document translation, with formats including Android and Apple iOS strings, .NET resources, gettext, JSON, XLIFF, YAML, and WebExtension JSON.

Translators can use screenshots, nearby strings, source references, shared glossaries, and translation memory to understand meaning and keep terminology consistent. Customizable quality checks, discussion, and review help teams catch issues before accepting work. These controls suit projects where translation quality needs a deliberate review process, though teams must establish that process themselves.

Teams can work with human translation alone or optionally offer machine-translation and LLM suggestions. Suggestions still require human acceptance and reviewer approval, so AI is an aid rather than an automatic publishing path. Repository integrations, an API, add-ons, and import and export tools support automation. Weblate can be installed using pip or Docker, with additional guides for OpenShift and Kubernetes; self-hosting offers control and generous capacity, but puts operation in the team's hands.

Pricing

All cloud plans include a 14-day gratis trial. Cloud pricing is based on hosted strings across languages, counting the source language too, so the relevant tier depends on the full project size rather than only translated text. Larger projects can request custom hosting.

Gratis Weblate is useful for eligible public libre projects, but its one-project cap and public-only rule rule it out for private work. The free self-hosted option removes hosted-string and project caps, while requiring the team to run the platform; optional paid support is available. Paid cloud plans retain unlimited projects, languages, and components, but string capacity rises by tier. Subscribers can contact a dedicated support team, and paid self-hosted support includes priority email support and other response or maintenance benefits.

Platforms

Weblate is available through the web and API, and supports Linux and self-hosted deployment. The documented installation routes include pip and Docker, with guidance for OpenShift and Kubernetes.

Who it's for

Weblate is a sensible choice for software teams that localize continuously, need translation context and review, and want translations tracked with code. Self-hosting particularly suits teams able to operate their own service; cloud tiers suit teams preferring hosted service and able to match their string volume to a monthly plan. Organizations handling private projects should choose paid cloud or self-hosting rather than the public-project-only gratis hosting.

Pros and cons

Pros

• Repository-connected workflows return translations alongside code, reducing the separation between development and localization.
• Screenshots, source references, glossaries, memory, and review tools give teams several ways to improve context and consistency.
• Free self-hosting has no hosted-string, language, project, or component cap.
• Human approval remains part of optional machine and LLM suggestion workflows.

Cons

• Gratis hosted service is limited to public libre projects and one project, so it is not suitable for private work.
• Cloud capacity is measured across languages and includes the source language, which can push larger projects into higher monthly tiers.
• Self-hosting avoids those capacity caps but requires the team to install and operate Weblate.

Alternatives

Crowdin is another freemium option with a free plan and broad platform support; consider it if its supported Android, iOS, Linux, macOS, web, and Windows environments better match your team's needs.

locize may suit smaller projects looking for a defined entry allowance: its free plan includes 2,000 words, two languages, five namespaces, one user, and 100K standard CDN downloads per month.

OneSky is another freemium alternative for teams considering AI-driven quality estimation or multi-agent translation.

Tolgee is worth comparing if a free hosted allowance with 30,000 words and three seats is a closer fit; its free plan also includes standard localization features, automation, and machine translation.

Live Link Face is a free iOS and Android app, rather than a repository localization platform.

Transglot offers a free plan with 100,000 words to start, then 10,000 per month, for one project, 14 target languages, and three seats; consider it if those limits suit your team.

ECI Flow is free of charge to qualified game development companies and publishers.

Localazy may fit teams that need a free allowance of 200 source keys with unlimited seats and languages.

Verdict

Choose Weblate if your software team wants repository-connected localization with meaningful translation context and review, and either has the capacity to self-host or can budget for a cloud string tier. Its strongest case is keeping translation work in the development workflow while preserving human oversight. Look elsewhere if you need private work on a free hosted plan or a translation tool not centered on software repositories.
