FAQ
What happens when I exceed 50K SaaS calls?+
Pay ¥0.02/call, or upgrade to Enterprise (unlimited calls). No service interruption on overage — settled monthly.
What's the difference between open-source SDK and SaaS?+
Open-source SDK only includes client-side signing/calling code — you implement the backend yourself. SaaS subscription calls um.yunjii.cn API directly, backend maintained by us, ready out of the box.
What code is included in the private license?+
Complete PHP backend + Next.js frontend + docs source + deploy scripts. Delivered under NDA, can be modified, but not resold.
Is migrating from SaaS to private hard?+
No. Database schema is fully compatible, SDK calls are identical. We provide migration scripts + 1-on-1 technical support, averaging 2 days to complete.
Is there a free trial?+
SaaS subscription has a 14-day free trial, no credit card required. All features are open during trial, data is retained for 30 days after expiry for renewal.
