Bytecode Viewer is a Java reverse engineering suite with a GUI that includes Java and APK decompilers, bytecode editors and a compiler. It supports loading classes, jars and Android APKs, and is released as free and open source under GPL v3.
A family of online interpreters for a growing list of practical and recreational programming languages. Users pick a language and type code, which is sent to a sandboxed TIO arena for execution and results returned to the browser. Code and input can be shared through a client-side permalink. The web app is free of charge, ad-free, and does not use tracking cookies.
OverAPI.com is a site that collects all the cheat sheets. It organizes reference sheets for programming languages, frameworks, and developer tools, listing topics from Python and JavaScript to HTML, SQL, and Linux.
JavaDecompiler provides an online interface for extracting source code from .class and .jar binary files. It presents several Java decompilers, including CFR, JD, Procyon, Fernflower and JAD, with notes on each. The site also links to an APK decompiler and a knowledge base. JAD is listed for historical reasons only.
CheatSheets.zip is a repository of quick reference sheets and cheat sheets for developers, described as crafted by the open community. It lists cheat sheets covering topics such as AI tools, programming languages, operating systems, databases and keyboard shortcuts.
WhichJDK is a site giving independent recommendations on which version of the JDK to use. It notes that OpenJDK is the open source reference implementation of the Java SE specification, while binary distributions are provided by different vendors and differ in licenses, commercial support, supported platforms and update frequency. It recommends Adoptium Eclipse Temurin 25.
