Is AWS Copilot deprecated?

Yes, AWS Copilot CLI is indeed being deprecated. According to an official announcement from AWS, support for AWS Copilot CLI will end on February 3, 2025.

As of November 4, 2024, AWS Copilot CLI entered maintenance mode. During this period, it will only receive critical bug fixes and security updates. After February 3, 2025, the CLI will no longer receive any updates or bug fixes.

Regarding your existing production workloads that use Copilot, AWS has stated that existing applications using the CLI will continue to function as intended, unless there is a breaking change to how AWS services used by AWS Copilot CLI work. Such changes are uncommon and would be communicated if they were to occur.

After the end-of-support date, you will still be able to use, access, and fork the CLI on GitHub, as the repository will be archived and made read-only. However, it's important to note that no further official support or updates will be provided after this date.

Given this information, it would be advisable to start planning a migration strategy for your production workloads that currently rely on AWS Copilot. While you can continue using it after the deprecation date, you may want to explore alternative solutions that will receive ongoing support and updates from AWS in the long term.
