Announcing the end-of-support for the AWS Copilot CLI

This article announces the end-of-support for AWS Copilot CLI on June 12, 2026, and provides migration guidance to alternative AWS container deployment solutions.

• AWS Copilot CLI reaches end-of-support June 12, 2026; remains open-source on GitHub
• Copilot supported six service patterns: Load Balanced Web, Request-Driven Web, Backend, Worker, Scheduled Job, Static Site
• Amazon ECS Express Mode offers simplified deployment with automatic infrastructure provisioning and HTTPS/TLS
• AWS CDK L3 constructs provide infrastructure-as-code with full customization and type-safe definitions
• Migration paths include adopting existing CloudFormation templates or deploying with Express Mode or CDK
• Express Mode supports up to 25 services per load balancer with cost optimization benefits
• CDK enables multi-language support, testing, and reusable infrastructure patterns across teams
• Migration steps: inventory applications, prepare container images, select approach, deploy, validate, update CI/CD

AWS recommends migrating Copilot users to ECS Express Mode for simplicity or AWS CDK for advanced customization, both providing improved operational visibility and AWS ecosystem integration.
