OpenJDK Reviews in 2026

Audience

Developers looking for a free and open source implementation of the Java platform

About OpenJDK

The place to collaborate on an open-source implementation of the Java platform, standard edition, and related projects. Download and install the latest open-source JDK. Oracle’s free, GPL-licensed, production-ready OpenJDK JDK 21 binaries for Linux, macOS, and Windows are available, Oracle’s commercially-licensed JDK 21 binaries, based on the same code, are available as well. Browse the code on the web, clone a repository to make a local copy, and contribute a patch to fix a bug, enhance an existing component, or define a new feature. OpenJDK provides source code that developers can use to build their binaries. Consequently, users are responsible for compiling the code and generating the Java runtime tailored to their specific platform. The JDK is a complex software project. Building it requires a certain amount of technical expertise, a fair number of dependencies on external software, and reasonably powerful hardware.

VSCodium

Microsoft’s vscode source code is open source (MIT-licensed), but the product available for download (Visual Studio Code) is licensed under this not-FLOSS license and contains telemetry/tracking. The VSCodium project exists so that you don’t have to download+build from source. This project includes special build scripts that clone Microsoft’s vscode repo, run the build commands, and upload the resulting binaries for you to GitHub releases. These binaries are licensed under the MIT license. Telemetry is disabled. Note for Mac OS X Mojave users, if you see “App can’t be opened because Apple cannot check it for malicious software” when opening VSCodium the first time, you can right-click the application and choose Open. This should only be required the first time opening on Mojave. The most up-to-date information on migrating from Visual Studio Code and other quirks you might encounter are documented.
