Frequently Asked Questions
Do I need to replace Epic Online Services to use Extend?
No. Extend is designed to work alongside Epic Online Services. You continue using EOS for core online features while Extend handles custom backend logic that does not belong in the client.
Is this an official Epic Online Services integration?
Yes. AccelByte is an official Epic Online Services partner, and Extend is built and supported as part of the EOS partner ecosystem.
Can I develop and debug Extend code locally?
Yes. Extend supports local development and testing, with logs and runtime visibility available once deployed.
Do I have to migrate my EOS data to AccelByte?
No. AccelByte Extend acts as a logic layer. You keep your Epic Identity and core data while using Extend to handle the custom backend processing your game requires.
How is Extend priced?
Extend pricing is based on the VM-hours used by the server your code runs on and designed to scale with how much backend logic you run. You can get started with a free trial, with no credit card required. Learn more about Extend pricing.
