Message sync and device recovery

Ordering, delivery receipts, unread counts, and reconnect synchronization need explicit rules. Offline sends must not create duplicate messages when a connection returns.

Is end-to-end encryption part of basic chat

No. Key management, device verification, backups, and recovery require specialist design. Do not label ordinary transport encryption as end-to-end encryption.

A cheaper way to start with Superapp

Build a focused version yourself before commissioning a full custom project. Superapp Pro is $25 a month; the subscription covers its plan allowance, while your time, extra usage, integrations, hosting, and specialist work remain part of the budget. A Superapp site is an alternative implementation, not a guarantee of WordPress or Shopify compatibility.

Sources and methodology

Rates are global marketplace benchmarks, not US-only agency quotes. Freelancer and agency ranges overlap because they describe different samples. WordPress.com Personal and Shopify Basic use annual billing, exclude introductory promotions and taxes, and replace the hosting budget. Feature hours and recurring budgets are our explicit planning assumptions.
