Frequently Asked Questions

? Is Weblate hard to install?

Weblate simplifies deployment via Docker Compose or Kubernetes, making setup accessible for most users. Traditional Python/Django setups require dependencies, but detailed docs guide you through every step.

? Is it a good alternative to Crowdin or Lokalise?

Yes—Weblate matches core features (collaboration, VCS integration) but as open-source self-hosted software. It’s ideal for teams prioritizing data ownership over proprietary SaaS subscriptions.

? Is Weblate completely free?

The self-hosted core is 100% free under GPLv3. A hosted Weblate Cloud option exists with paid plans, but all self-hosted features (including advanced tools) are available at no cost.
