Developer Tools brings a practical toolbox of everyday development utilities directly into IntelliJ-based IDEs. It keeps common tasks such as encoding data, transforming text, validating JSON, generating identifiers, inspecting archives, formatting code and SQL, and checking certificates inside the IDE, so you do not need to switch to separate web tools or command-line snippets.

The full toolbox is available in both a persistent tool window and a standalone dialog. Tools can have multiple named workbenches, so you can keep separate inputs and configurations for different tasks. Frequently used text operations are also available from the editor popup menu and as intentions; depending on the action, they work on selected text or on the Java/Kotlin string or identifier at the caret.
Plugin settings are available in IntelliJ IDEA's settings/preferences under Tools | Developer Tools.
The tool window is available through View | Tool Windows | Developer Tools. Inputs, selected tools, expanded menu groups, and tool configuration are stored per project.
The dialog is available from IntelliJ IDEA's main menu under Tools | Developer Tools.
To add the "Open Dialog" action to the main toolbar, enable it in IntelliJ IDEA's settings/preferences under Tools | Developer Tools, or add it manually via Customize Toolbar... | Add Actions... | Developer Tools.
Dialog inputs, selected tools, expanded menu groups, and tool configuration are stored at the application level.
This plugin is not treated as a library, so code changes do not necessarily follow semantic versioning rules.
