Eclipse Che vs IntelliJ IDEA

Eclipse Che is an open-source development environment that runs IDEs in Kubernetes. Users create workspaces from a Git repository or sample, then access them online through a browser. Visual Studio Code and JetBrains IDEs are available. Workspace definitions use Devfiles, YAML files that can be versioned with application source code, and a devcontainer configuration is listed. GitHub, GitLab, and Bitbucket identities can connect through OAuth. Teams can share a development setup by URL, and Che can run on public or private Kubernetes clusters, including self-hosted deployments. Access uses OIDC authentication and Kubernetes RBAC authorization. Enterprise support includes air-gapped networks, TLS certificates, proxies, and FIPS. Code is cloned to persistent storage by default, but other file changes disappear when a workspace stops unless stored on a persistent volume. Che is free, with no stated usage limits.

IntelliJ IDEA is an IDE for professional Java and Kotlin development, available on Windows, macOS, and Linux. It offers context-aware completion, static analysis, and automated refactoring. The JVM debugger includes breakpoints, variable inspection, expression evaluation, and step-by-step execution. Gradle and Maven integrations cover building, packaging, testing, and deployment, while version-control support includes Git, Mercurial, Perforce, and Subversion. Users can process GitHub pull requests in the IDE, and plugins from JetBrains Marketplace add support for other languages, frameworks, and technologies. Core Java and Kotlin functionality remains free after the included 30-day Ultimate trial ends. The Ultimate subscription adds advanced tools and integrations and costs $100.00 for the first year, $199.00 for the second year, and $159.00 per year from the third year onward. Listed minimum hardware is a 4-core x86_64 or arm64 CPU, 8 GB total RAM, and 10 GB of disk space. Users can choose in IDE settings whether to share anonymous usage data.
