What is Groovy?
Apache Groovy is a dynamic scripting language for the JVM that adds syntactic sugar on top of Java: closures, builders, GStrings, and metaprogramming via methodMissing / propertyMissing. It powers Gradle's build DSL and the Jenkins pipeline script (the Jenkinsfile is Groovy).
Why run Groovy in the browser
The JDK + Gradle + a Groovy-aware IDE is a hefty setup for a five-line script. A browser sandbox lets you try a Groovy idiom — a closure, a GString, a builder — and see it run on the JVM without that overhead. Our execution platform compiles and runs Groovy 3.0 with the JDK toolchain in seconds.
Common Groovy tasks
Gradle build scripts (apply plugin: 'java'), Jenkins pipelines (pipeline { agent any; stages { ... } }), Spock test specifications, Grails web apps, JSON/CSV slurping with JsonSlurper and CsvMapper, and DSL design. The sandbox runs Groovy 3.0.
Getting started with Groovy 3.0
Paste a snippet — def greet = { name -> println "hi, $name" }; greet("Tutorsbot") — hit Run, see stdout. The highlighter recognises Groovy syntax: GStrings (double-quoted strings with $var interpolation), closures { x -> ... }, optional semicolons, and the safe-navigation operator ?..

Frequently Asked Questions
- Is the Groovy online compiler free?
- Yes — Tutorsbot's Groovy compiler is completely free. No account required, no installation, and no usage limits.
- Do I need to install Groovy?
- No. The Groovy compiler runs entirely in your browser. No runtime, no SDK, no PATH configuration. Open the page and start coding.
- Is my Groovy code saved between sessions?
- Yes — your code autosaves to your browser's local storage so you can resume where you left off. You can also generate a shareable URL.
- Can I share Groovy code with others?
- Yes. Click the Share button to copy a URL that encodes your script. Anyone with the link can open and run it instantly — no account required on their end.
- Is the Groovy compiler safe to use?
- Absolutely. Every program runs in an isolated sandbox. Your local system is never exposed to the executed code, and nothing is persisted after the execution window.
