About Cloud9 IDE

Cloud9 IDE was one of the original browser-based development environments, pairing a web editor, terminal, and Linux workspace before cloud dev environments became mainstream. Its standalone c9.io product was absorbed into AWS Cloud9 after the acquisition, so the historical page should now frame Cloud9 as a legacy cloud IDE lineage rather than an active new-customer option.

The write-time source check found AWS documentation stating that AWS Cloud9 is no longer available to new customers, while existing customers can continue using the service. That exact new-customer closure note is the key trust signal for readers who still search for Cloud9 in 2026.

Teams looking for a current path should evaluate AWS IDE Toolkits, AWS CloudShell-style workflows, local IDEs connected to cloud resources, or cloud IDE products such as GitHub Codespaces and Gitpod. Keep this page for migration and historical context, not as a recommendation to start a fresh Cloud9 workspace.

Pricing & Platform Specs

Pricing Summary

No additional software charge for the AWS Cloud9 IDE itself ($0 license fee). Customers pay standard AWS infrastructure rates for underlying Amazon EC2 compute instances and Amazon EBS storage volumes provisioned to host the environment. Note: AWS closed new customer onboarding for Cloud9 in July 2024, but existing customers continue to be supported.

Supported Platforms

Was: browser IDE on c9.io/AWS Cloud9; successor paths include AWS IDE Toolkits, CloudShell-style workflows, local IDEs, Codespaces, and Gitpod.

Why it was discontinued

discontinued July 25, 2024

Cloud9’s standalone c9.io era ended after the AWS acquisition, and AWS Cloud9 itself is now a legacy service. AWS documentation states that Cloud9 is no longer available to new customers, while existing customers can continue to use it as normal. The practical replacement path is migration to current AWS developer tools or modern cloud IDEs rather than a revived Cloud9 product.

use instead: GitHub Codespaces, Gitpod, StackBlitz
