Is there any estimated timeframe for customer account ui extension, when the same will be available

[Amarjyt]

I build a customer account ui extension  to show some custom data from external api on account page. By what time shopify will make it available for live stores. 
and also suggest alternate way to show custom data for logged in users

Thanks

Hey @Amarjyt, there's no specific date yet, but Customer Account UI Extensions are expected to be publically available in December (https://shopify.dev/docs/apps/build/customer-accounts#release-timeline). Other than through this, the only way I am aware of to show custom data would be somewhere else on the storefront using Liquid code.
