It is released under the MIT licence. A commercial or hosted edition starts at $19 per month. Prices are published openly on the vendor's own pricing page. Pricing changes often, so verify at source before relying on it.","source":"https://expo.dev/pricing","question":"Is Expo free to use?","confidence":0.6},{"answer":"Expo supports the web, iOS, Android and a command-line interface. Platforms we have not confirmed are simply not listed here rather than ruled out.","source":"https://expo.dev/pricing","question":"What platforms does Expo support?","confidence":0.6},{"answer":"We have only confirmed a cloud / SaaS deployment for Expo, so it appears to be vendor-hosted. If a self-hosted option exists we have not found it documented publicly.","source":"https://expo.dev/pricing","question":"Can Expo be self-hosted?","confidence":0.6},{"answer":"We have confirmed 10 integrations for Expo, including Slack, maestro, Fastlane, Xcode, Android Studio, ADB, Metro and Webpack, plus 2 more. This is what we could verify from public sources, so the vendor may support others we have not indexed.","source":"https://expo.dev/pricing","question":"What does Expo integrate with?","confidence":0.6},{"answer":"We have independently confirmed SOC 2 and GDPR for Expo. Certifications we do not list are ones we have not been able to verify from public sources, which is not the same as Expo not holding them.

Pricing is quoted on request, across 2 plans (Extended Security Maintenance and Premium Security Maintenance), so the figure depends on your seat count and requirements. We record this as a pricing-transparency signal rather than guessing a number.
