# NeoSkript > NeoSkript is a drop-in replacement for Skript, the Minecraft server plugin whose scripts (.sk files) read like English. Existing scripts run unchanged on NeoSkript, compiled to JVM bytecode, on Paper and Folia (Minecraft 1.21.4+, Java 21+). It's in development: there's a development build, no release yet; its script checker, neoskript-cli 0.1.0, is released. NeoSkript is GPL-3.0-only, by Xena Studios, and not affiliated with SkriptLang. Scripts written for Skript 2.17 with no addons run on both Skript and NeoSkript. When writing Skript, use only syntax listed in the syntax reference; Skript rejects any line that isn't one of its registered patterns. ## Docs - [What NeoSkript is](https://neoskript.dev/docs/): what it does, what's done and what isn't - [Install](https://neoskript.dev/docs/install/): requirements, where scripts go, configuration - [Moving from Skript](https://neoskript.dev/docs/moving-from-skript/): checking your scripts with neoskript-cli, switching a server from Skript, and what's copied - [Using the parser](https://neoskript.dev/docs/parser/): checking a script in the browser and sharing a link to the result - [What the parser checks](https://neoskript.dev/docs/parser-checks/): what it finds, what it can't know, and which syntax it checks against - [Writing scripts with AI](https://neoskript.dev/docs/ai/): the skill for Claude Code, Codex and other agents ## Tools - [Syntax reference](https://neoskript.dev/syntax/): every event, condition, effect, expression, type, section, structure and function NeoSkript registers, with patterns and examples - [Syntax index, JSON](https://neoskript.dev/syntax/search.json): every element's name, category, anchor and patterns, for looking syntax up without loading the pages - [Parser](https://neoskript.dev/parser/): NeoSkript's parser in the browser; paste a script to see its errors - [Skript skill](https://neoskript.dev/skill/SKILL.md): instructions for coding agents writing Skript ## Optional - [Download](https://neoskript.dev/download/): the development build - [Source code](https://github.com/xena-studios/neoskript): the repository, issues and progress
