Frequently asked questions
What is Stringbase?+
Stringbase is an API-first translation management system (TMS) for product teams. It combines AI-powered translation with team collaboration — comments, @mentions, approval workflows, and over-the-air delivery — so your team can manage translations without spreadsheets or manual JSON file management.
How much does Stringbase cost?+
Stringbase has two plans. The Free plan includes 1 project, 1,000 keys, 5 languages, up to 5 members, and 5,000 AI translations per month. The Team plan is $49/month and includes unlimited projects, keys, languages, and members, plus 50,000 AI translations and glossary with AI enforcement.
Does Stringbase have a free plan?+
Yes. The Free plan is a real product, not a demo. You get full API access, OTA delivery, comments, @mentions, translation history, and dev/production environments. No credit card required.
How does AI translation work?+
When you add a translation key, Stringbase automatically translates it to all your configured target languages using AI. Translations appear with an “AI Translated” status and go through your team’s review workflow before being published to production.
Can I use Stringbase with my existing tech stack?+
Yes. Stringbase works with any stack — React, Next.js, Vue, Svelte, Flutter, React Native, or any other framework. The REST API returns standard JSON, so you can integrate it however you want.
What is OTA translation delivery?+
Over-the-air (OTA) delivery means your app fetches translations from Stringbase at runtime instead of bundling them at build time. When your team publishes a translation update, your users see it immediately — no app redeploy or app store review needed.
