Why it exists

Purpose

Every Hero Studios product needs intelligence — and it should come from one place that works today. Hero Code is an autonomous AI software engineering agent: describe a project in plain English and it designs, writes, and debugs real code for you — through the seven-slot HERO sequence or your own provider keys. It is the shared AI backbone of the ecosystem and the developer tool that powers everything else.

Who it's for

Developers who want an AI engineering team inside an IDE, Minecraft modders and game creators (skills for Minecraft modding, Godot and Blockbench), makers prototyping ideas fast, and every Hero Studios product that will consume the shared intelligence layer.

Key capabilities

Autonomous project building

Describe a project in plain English — the agent designs it and writes real multi-file code straight into your workspace, in Chat, Build, Review or Plan mode.

The HERO sequence

Seven specialist slots — NOVA, FORGE, SAGE, LENS, SCRIBE, ATLAS, SWIFT — resolved server-side to the best available engine, with metering and honest credits.

18 built-in skills

Minecraft modding, Godot, Blockbench and more — with built-in web search while it works.

A full IDE

27 languages with syntax highlighting, right-click Ask AI, terminal, Git, debugger, extensions marketplace and voice input.

One ecosystem

The shared intelligence layer every Hero Studios product consumes — CraftPilot first.

Features

Hero Agent — feature registry

22 features across 5 categories — 21 live, 1 planned. Every feature carries its real lifecycle.

HERO Sequence 3 features

7-slot HERO sequence live

NOVA, FORGE, SAGE, LENS, SCRIBE, ATLAS and SWIFT — seven specialist slots the server resolves to the best available engine. No vendor model ids anywhere in the UI.

Chat modes with Plan cards live

Chat, Build, Review and Plan — Plan lays out typed plan cards before a line is written, Build streams typed progress cards while files land in your workspace.

Command palette live

Ctrl+K opens the 68-entry command palette — every action, one keystroke away.

Chat & workspace 3 features

ChatsBar + conversations live

Left-rail ChatsBar with real, server-persisted conversations (D1), stable message ids, and Ctrl+B / Ctrl+N to toggle the bar and start a new chat.

Hero Memories live

Memories are extracted automatically, stored server-side and injected into later chats — manage them in the Memory Panel (Ctrl+M): edit, delete, export, opt out.

Chat dock live

Ctrl+Shift+C detaches the conversation into a docked pane while you edit.

Models & plans 3 features

Server-side metering live

Premium slot gates (401/402), a truthful credits_remaining counter and a per-slot usage chart in Plans — every slot call is metered honestly.

Encrypted BYOK keys live

Bring-your-own keys are encrypted at rest (PBKDF2-derived Fernet) and sent directly to the provider you chose — never logged or telemetried.

Plans & checkout planned

Free / Pro / Enterprise plans with upgrade at checkout on herostudios.dev — the shared plan syncs to the Agent within a minute. Coming next.

Editor & tools 8 features

27 languages, syntax highlighting live

27 programming languages with syntax highlighting in a VS Code-style IDE — see the docs language matrix for the honest per-capability scope.

Right-click Ask AI live

Right-click any code — ask the active slot to explain, fix, or improve it in place.

Built-in terminal live

A real terminal running shell commands against your workspace.

Git integration live

Version control from inside the IDE.

Built-in debugger live

Step through and debug your projects without leaving the agent.

Extensions marketplace live

Install and manage plugins from the built-in extensions marketplace.

Web search live

Built-in web search — the agent researches docs, APIs and errors while it works.

Voice input live

Dictate prompts with the Web Speech API, with Whisper transcription fallback in the desktop shell.

Getting started 5 features

18 built-in skills live

18 built-in skills (game modding, Blockbench, Godot, and more) that specialise the agent per domain.

Browser app — live now live

agent.herostudios.dev is live: no install, no setup, your workspace in the browser.

Desktop app (Windows) beta-not-published

Windows installer built locally (0.8.0) — not published yet; browser version is live now. macOS and Linux installers are still planned.

Interactive tutorial live

An interactive tutorial walks beginners from zero to their first AI-built project.

herostudios.dev integration live

Quick start

Get started with Hero Agent in minutes

Follow these steps — most installs take under five minutes.

Step 1

Launch in the browser — open agent.herostudios.dev and sign in with your herostudios.dev account if you want cloud sync. No install needed; the Windows desktop installer is built locally (0.8.0) but not published yet.

Step 2

First run: create a project, then pick a mode in the composer — Chat, Build, Review or Plan.

Step 3

Choose your slot from the HERO sequence — NOVA for everyday chat, FORGE for building, SAGE for reasoning, LENS for review, SCRIBE for docs, ATLAS for long context, SWIFT for speed.

Step 4

Describe your project — the agent writes real files that appear in the explorer instantly. Plan mode lays out typed plan cards before a line is written; Build streams typed progress cards while it works.

Step 5

Work in the IDE: edit with syntax highlighting across 27 languages, run commands in the terminal, use Git and the debugger, and right-click any code to Ask AI to explain, fix or improve it.

Step 6

Keep your context: the ChatsBar (Ctrl+B) keeps every conversation, Ctrl+N starts a new one, and Ctrl+M opens the Memory Panel to edit, delete, export or opt out of memories.

Step 7

Follow the interactive tutorial if you are new — it walks from zero to your first AI-built project — then install extra capabilities from the extensions marketplace.

FAQ

Questions, answered

What is Hero Code?

Hero Code is Hero Agent's product name — an autonomous AI software engineering agent that designs, builds and debugs entire projects from a plain-English description, with a full IDE around it.

What is the current version?

0.8.0 — released 2026-11-05 on the stable channel. Every older release stays visible in the changelog and on the releases page as history.

What are the chat modes?

Chat (talk it through), Build (write the files), Review (find problems with scored findings) and Plan (lay out typed plan cards before any code is written). You switch modes in the composer.

Do I need my own API keys?

No. The sequence slots are hosted — NOVA, FORGE, SCRIBE and SWIFT are included on the free plan, metering gates the premium slots. BYOK is optional: if you bring a key it is encrypted at rest and sent directly to your provider, never logged or telemetried.

What do the 18 built-in skills cover?

They specialise the agent for real domains — Minecraft modding, Godot, Blockbench and more — and the extensions marketplace adds more.

Which programming languages are supported?

27 programming languages with syntax highlighting in the editor. The docs language matrix is honest about scope: highlighting ✓; language servers, formatters and per-language debug adapters are not shipped — Ask AI does that work.

What developer tools are built in?

A real terminal, Git, a debugger, right-click 'Ask AI' for explain/fix/improve, voice input, and an extensions marketplace for plugins.

Is it released?

Yes — 0.8.0 is the current release on the stable channel (2026-11-05). The browser app at agent.herostudios.dev is live now and is the supported path today.

Is there a desktop app?

The Windows installer is built locally (0.8.0) but not published yet — there are no public desktop binaries to download today, so use the browser version, which is live now. macOS and Linux installers are planned. The desktop shell wraps the same local app (Python backend plus React IDE).

Does it work with Minecraft?

Yes — it is Minecraft-specialised through built-in skills (Minecraft modding, Blockbench, and Godot for game projects) plus web search, and it is the planned AI backbone for CraftPilot and other Hero Studios products.

How does it relate to the rest of the ecosystem?

It is the shared intelligence layer — CraftPilot's assistant is the first planned consumer, followed by Hero Client and Redstone Debugger AI features.

Compatibility & limitations

What to know
