Describe any plugin in plain English. StackNest generates the Java, compiles it against the real Paper API, auto-fixes any errors (up to 5 passes), and delivers a server-ready .jar — not a code snippet that breaks in production.
Every generation is compiled against the real Paper API, statically analysed, auto-healed if needed, and packaged as a .jar — not a code snippet. No compiler setup. No Java experience needed.
Complex plugins follow real backend patterns: layered manager classes, async-safe player data loading with CompletableFuture dedup maps, bounded write queues, config-driven backpressure semaphores, stale-task guards after /reload, and copy-on-write data snapshots. Not AI toy output — actual senior-level code.
Describe your plugin in plain English. StackNest generates the Java source, compiles it against the real Paper API, runs static analysis, and packages a .jar that drops straight onto your server. No compiler setup. No boilerplate. No guesswork.
When a generation misses the mark, the system reads compile and YAML feedback, then retries with targeted corrections instead of forcing you to start over.
AutomaticFree usage is optimized for fast generation. Paid plans unlock higher-quality cloud reasoning, deeper repair flows, and better reliability for larger plugin requests.
Free & PremiumBrowse examples, inspect outputs, and publish your own projects so other server owners can learn from real prompts, real plugin structures, and working releases.
NewReview and refine generated files in the browser with syntax highlighting, multi-file tabs, JAR export, and source downloads when you want to continue locally.
NewUse /generate and /validate inside your Discord server without opening a browser. Great for server teams where the conversation is already in Discord. Plus: generate a full Discord bot, deploy it to StackNest hosting, and manage it from your dashboard.
Paste server logs or upload crash output to get a cleaner diagnosis, likely causes, and actionable next steps without digging through stack traces manually.
NewDownload a ready-to-test JAR, keep the source for manual edits, or move into your normal Paper workflow when a project outgrows one-click generation.
Switch to Mod mode in the generator, pick your loader and Minecraft version, and get a complete Java mod — main class, metadata file, Gradle build config, and feature stubs like custom items, blocks, commands, and events.
NewAfter generating a plugin, Starter and above can click Test on Server to boot a real Paper 26.1 instance, load the plugin, and get a structured report — errors, warnings, stack traces, and AI-powered fix hints — all in under 60 seconds. No server required on your end.
Starter+Two new modes for non-Java workflows. Skript generates Paper-compatible .sk scripts with correct indentation, event syntax, and variable scopes — based on the full Skript 2.x docs. Datapacks output a complete file tree: pack.mcmeta, functions, advancements, recipes, loot tables, and scoreboard logic ready for MC 1.21+.
The most complete AI Minecraft plugin generator: Paper, Folia, Spigot, Velocity, Fabric, Forge, NeoForge, Skript, and vanilla datapacks — all from one place.

Every generation runs through 12 verified stages: live API search, AI generation, real javac compilation, static analysis, YAML validation, quality review, and up to 5 auto-fix passes. The JAR you get has been compiled and healed before it reaches you.
No credit card required to get started. Upgrade any time for higher limits and cloud AI features.
After generating code, StackNest compiles it with real javac against the Paper API. If there are errors, the exact compiler output is fed back to the AI with a targeted instruction to fix only the broken lines — not regenerate from scratch. This loop repeats up to 5 times automatically. Most plugins reach zero errors by pass 2 or 3. You never see a broken generation.
ChatGPT and GitHub Copilot produce code snippets — they don't compile them, package them as a .jar, or validate the plugin.yml. StackNest runs a 12-step pipeline: live Paper API search, AI generation, real javac compilation, static analysis, YAML validation, quality review, and up to 5 auto-healing passes. What you download loads directly onto a Paper server and runs — no debugging, no missing imports, no broken descriptors.
Yes. The StackNest Discord bot supports /generate and /validate slash commands. Type your plugin description into Discord, get the generated code back in the channel, and use /validate to run a deep code review — all without leaving Discord. Join the server at discord.gg/vebvd8PRzv and link your account to get started.
Yes. Every generation runs through a real Java compiler (javac) against the PaperMC API. If compilation fails, the feedback loop automatically heals the code and retries up to 5 times. Plugins marked "Compiled Successfully" have 0 errors and are ready to drop into your server.
StackNest targets Paper 26.1 by default and also supports Paper 1.21.x compatibility workflows, Folia, proxy-oriented builds, and Skript generation for faster scripting use cases. If you need a specific target, say so directly in the prompt.
Yes. StackNest now supports source migration for older plugins. Upload a source ZIP or provide a GitHub repository URL and StackNest applies mechanical upgrade fixes for modern Paper APIs (including deprecated import swaps and version updates), then returns a downloadable migrated source bundle with a clear diff of what changed.
Free requests prioritize fast, cost-efficient generation. Paid plans unlock stronger cloud reasoning, better recovery for larger requests, and deeper validation tooling. The platform automatically chooses the best available path for the plan you are on.
Absolutely. Every generated plugin can be opened in the built-in web editor, which provides Java and YAML syntax highlighting, multi-file tabs, one-click deployable JAR download, and optional source ZIP export — no local tooling required.
Yes. Free accounts get 3 full plugin generations per month and 20 prompt previews. Starter, Pro, and Studio raise limits and unlock stronger generation, support, and collaboration features as your usage grows.
Yes. Switch to Mods mode in the generator using the pill toggle at the top of the composer. Choose your mod loader (Fabric, Forge, or NeoForge) and Minecraft version, select feature chips like custom items, blocks, commands, or events, then hit Generate. The output includes a main Java class, the mod metadata file (fabric.mod.json or mods.toml), and a Gradle build stub. Mod generation uses the cloud AI tier for better quality results.
Join the StackNest Discord to use /generate and /validate slash commands directly in your server — no browser needed. Also get prompt help, product updates, and support when a generation needs another pass.

StackNest is the only AI Minecraft plugin generator that runs a complete build pipeline end-to-end. Unlike pasting code out of ChatGPT, StackNest compiles every generation against the real Paper 26.1 API, runs static analysis for deprecated methods and missing registrations, validates the plugin.yml descriptor, and then auto-fixes any compile errors through up to five targeted AI repair passes — all before the JAR reaches your download button.
Generation works across the full modern Minecraft ecosystem: Paper and Spigot plugins, Folia multi-threaded plugins, Velocity and BungeeCord proxy plugins, Fabric mods, Forge and NeoForge mods, Skript scripts, and vanilla datapacks. Whether you need a shop plugin, a custom levelling system, a Folia-safe minigame, or a complete economy suite — describe it in plain English and StackNest handles the rest.
Server owners have generated over 10,000 plugins and mods with StackNest. The community gallery lets you browse real examples, and the built-in plugin editor lets you refine any generated file in the browser. Need to migrate a legacy 1.16 plugin? Upload the ZIP and StackNest applies modern Paper API changes automatically.
