A game dev terminal that knows your project cold.

Your GDD stays loaded. Claude reads it before every session, along with your stack, your tasks, and last session's notes.

$9 early access · No subscription · Windows (Mac & Linux coming)

DevForge is a structured UI that wraps AI coding tools. It's not a game engine and it's not going to design your game. You make the design decisions. DevForge handles context, modes, and version control so Claude stays focused on your project.

Your GDD Runs the Show

Claude reads your design doc before every prompt. Your vision stays intact whether you're writing code, testing balance, or drafting store copy.

14 Modes, 14 Jobs

DISCUSS talks design. IMPLEMENT writes code. PITCH stress-tests your scope. Each mode gives Claude one job and the right context for it.

Git Safety Net

Session branches, safety snapshots, one-click undo. Built for people who don't touch git and don't want to learn.

Nothing Gets Lost

Your session notes, task progress, project rules, and GDD sections ship with each prompt. You pick up exactly where you stopped.

Claude Learns Your Rules

After each session, Ollama reads the transcript and suggests project rules: corrections, conventions, gotchas you hit during the session. Accept, edit, or reject each one. Claude reads them next session.

Watch Claude Work

A live activity feed shows every file read, edit, and bash command. Toggle the thinking display to see Claude's reasoning. Press Escape to stop mid-execution.

Two themes.

DevForge in SNES Light theme — SNES Light

14 modes. One job each.

Analog Mode for tabletop design.

Toggle Analog in the footer and all 14 modes shift to tabletop. IMPLEMENT writes rules text and component specs instead of code. DEBUG finds rules contradictions. QA audits component consistency and first-play clarity. MARKETING writes Kickstarter pages and BoardGameGeek listings.

Design a board game with Analog on, then flip it off and use Implement to build the digital version. Your GDD carries over.

START. Work. END.

START

Creates a safety snapshot and optionally a session branch. If Ollama is running, it summarizes your project state so Claude starts oriented.

Work

Pick a mode, type what you want, send. Your project context ships with each prompt. The diff viewer, task panel, and git status refresh after each response.

END

Review all changes in the diff viewer. Write session notes (free via Ollama, or use Claude). Undo the entire session back to the snapshot if anything went wrong.

Up to 4 sessions at once.

Click + on the terminal tab bar to open a parallel session. Each tab gets its own git worktree, its own branch, its own Claude session with resume. You work on multiple tasks and they stay isolated. When you're done, MERGE folds changes back into your main branch. CLOSE discards.

Capped at 4 tabs since each one burns tokens independently. Tab switching is instant. Each terminal keeps its full scrollback.

There's also a separate BUILD/TEST terminal (toggle with the BUILD button) that runs your project's build and test commands apart from Claude's output. Stack-aware: cargo build for Rust, npm run build for HTML/Phaser, and so on.

Built-in tools.

BookFinder General

MCP server for Research mode. Hit BOOK SEARCH and Claude searches Anna's Archive, downloads the best match, extracts text, and summarizes findings for your project. Summaries save to the knowledge bank and show up in future prompts. Optional, free.

Anti-Slop Filter

10-rule post-processing system applied to share summaries, Marketing output, and AI-generated session notes. Strips em dashes, filler phrases, passive voice, and false agency. Your writing sounds like you wrote it.

Ollama (Free Local AI)

Optional. Runs locally so you don't burn provider tokens: AI Notes, smart context briefings, prompt expansion, smart routing, diff descriptions, GDD suggestions, project rule extraction, and an ASK bot with live visibility into Claude's current task. Ask "what is Claude working on?" mid-session and get a real answer. Everything works without Ollama. You just lose the free stuff.

47 skills. Injected when relevant.

33 digital: Roguelike architecture, platformer mechanics, state machines, collision detection, camera systems, pathfinding, dialogue trees, save/load, inventory, animation, audio, particles, shaders, OWASP security auditing, WCAG accessibility, visual diagrams & charts, plus stack-specific patterns for all 16 platforms.

14 analog: Rules writing, component design, balance & probability, hex maps, area movement, point-to-point maps, solitaire bot systems, wargame scale, VASSAL modules, Tabletop Simulator mods, print & play layout, Nandeck card layout.

16 platforms.

Godot 4, Unity, Unreal, Rust, Python, Love2D, GameMaker, RPG Maker, Phaser 3, HTML5, PICO-8, GB Studio, NES, Game Boy, Genesis, GBA. Plus a stack-agnostic "Undecided" option where FORGE recommends the right platform after learning your game. DevForge injects stack-specific build commands, docs links, and coding conventions into your prompts.

Built for Claude Code. Open to others.

Claude Code is the tested, recommended provider. You get session resume, streaming JSON output, direct file editing, context window tracking, and cost reporting. DevForge detects your CLI version at startup and warns you if an update changes something.

Aider, Codex CLI, and Gemini CLI are configured and the architecture supports them, but they haven't been tested in real workflows yet. For providers without session memory, DevForge injects heavier context: session notes, conversation log, GDD sections, code map.

Looking for testers willing to try DevForge with Aider, Codex, or Gemini and report back. Free access for multi-provider testers.

Windows today. Mac and Linux next.

DevForge is developed and tested on Windows. Tauri 2 builds for all three platforms, and there's nothing Windows-specific in the codebase, but Mac and Linux haven't been tested yet.

On Mac or Linux and willing to test? Free access for platform testers who report bugs.

Everything else.

Voice Profile Paste writing samples into Marketing mode. You get output in your voice.
Code Map Auto-generated file structure summary. Claude doesn't waste tokens exploring your repo.
Phase Tracker Visual progress bar parsed from your task list checkboxes.
Scope Meter Auto-calculated from lines of code, file count, git commits, GDD size, tasks, and stack. Ships with every prompt as a guardrail. Switches to manual target mode in Forge.
Knowledge Banks Per-project storage for Research, QA, Marketing, and Instruct, plus a global cross-project bank.
PDF Export One-pagers, press kits, and save-as-PDF from Marketing mode.
Session Transcripts Every Claude response saved as markdown. Browse, rename, filter, or delete past transcripts. Load any transcript as context for your next prompt.
Diagram Generation Quick actions in 8 modes to generate architecture diagrams, flowcharts, infographics, and comparison charts as PNG. Mention "diagram" or "chart" in any task and the render skill auto-injects.
Cost Tracking Footer shows "WORK DONE: $X.XX" with color-coded daily spend. Per-project totals so you see which games get the most AI investment. DevForge tracks usage against your existing AI subscription. No separate billing.
/CONTEXT Live session state: model, CLI version, context window usage bar (color-coded), token breakdown including cache hits, session cost.
/USAGE Today's and last 7 days' cost, tokens, sessions, daily average. Powered by ccusage.
CLI Resilience DevForge detects your provider's CLI version at startup. If an update introduces breaking changes, you get a warning in the log panel instead of silent failures.
Two Themes CRT Dark (retro terminal) and SNES Light (Super Nintendo palette).
Oryx Sprites + SFX 14 pixel art characters with idle, running, success, and error animations. 8-bit sound effects. All toggleable.
