A kanban board that orchestrates AI coding agents. Point it at your local projects, describe what you want built, and PlateSpinner spawns headless AI sessions (Claude Code, Codex, or Gemini CLI) to generate tasks, plan implementations, write code, and commit changes — while you watch from a drag-and-drop board.
How It Works
PlateSpinner manages a three-phase pipeline for each task:
1. Propose
Describe what you want ("add dark mode", "refactor the auth module", "find and fix bugs") and PlateSpinner spawns a read-only AI session that analyzes your entire codebase. It returns a structured list of tasks, each with a title, description, rationale, and effort estimate. Tasks appear in the Proposed column.
You can also use built-in prompt templates like the "Pareto" templates, which ask the AI to identify the highest-impact improvements across your codebase.
2. Plan
Click Plan on any proposed task. PlateSpinner spawns another read-only AI session that produces a concrete implementation plan — specific files to change, functions to write, tests to add. The plan is stored on the task card and visible before you commit to execution.
3. Execute
Click Execute and PlateSpinner spawns a full-access AI session with write permissions (Read, Write, Edit, Bash). The agent follows the plan, writes code, runs tests, and commits. You see real-time progress via WebSocket — files changed, insertions/deletions, agent output streaming live.
After execution:
- Diffs are captured and viewable in the built-in diff viewer
- Branch-per-task mode (configurable) creates an isolated branch like
kanban/task-a1b2c3d4-add-dark-mode - Auto-test can run your project's test suite after each commit
- Cost tracking records token usage and dollar cost per task and per project
You review the changes, then push when ready.
The Autoclicker
The autoclicker is PlateSpinner's fully autonomous mode. Enable it per-project and it runs a continuous loop:
- An AI judge analyzes the project state (existing tasks, git history, test results, budget)
- The judge decides what to do next: propose new tasks, plan an existing one, or execute
- PlateSpinner carries out the decision, then loops back to the judge
It's like Cookie Clicker for your codebase — you enable it and watch the tasks flow through the pipeline. Configurable parallelism (up to 10 concurrent agents), per-project budget caps, and automatic backoff on failures keep it from going off the rails.
Prerequisites
- Node.js 18+
- At least one AI CLI tool installed and on your PATH:
- Claude Code — recommended, supports structured output and tool control
- Codex CLI — optional
- Gemini CLI — optional
PlateSpinner spawns these as headless child processes. It doesn't call any cloud APIs directly — it invokes the CLI tools the same way you would from a terminal, just non-interactively.
Quick Start
git clone https://github.com/moridinamael/platespinner.git
cd platespinner
npm install
npm startOpen http://localhost:3001, click Add Project, and point it at a local codebase directory.
Development
Run the frontend (Vite) and backend (Express) concurrently with hot reload:
- Frontend:
http://localhost:5173(proxies API/WebSocket to backend) - Backend:
http://localhost:3001
Run tests:
Configuration
Copy .env.example to .env and adjust as needed:
| Variable | Default | Description |
|---|---|---|
PORT |
3001 |
Server port |
RAILWAY_BIN |
railway |
Path to Railway CLI binary |
DEBUG_AUTOCLICKER |
off | Enable debug logging for autoclicker judgment agent |
Per-Project Settings
Each project has its own configuration accessible in the UI:
- Branch strategy —
branch-per-task(isolated branches) ordirect(commit to current branch) - Auto-test on commit — automatically run tests after each execution
- Test command — override auto-detected test framework
- Budget limit — cap total spend per project (blocks execution when reached)
- Model selection — choose which AI model to use (Claude Opus, Gemini Pro, GPT Codex)
Features
- Drag-and-drop kanban board — reorder tasks and projects, move tasks between columns
- Command palette (
Ctrl+K) — quick access to actions and navigation - Keyboard shortcuts — navigate and act without the mouse
- Dark / light theme — respects system preference, toggleable
- Real-time streaming — WebSocket updates show agent progress, git status, and cost as execution happens
- Diff viewer — review every line of AI-generated changes before pushing
- Agent replay — inspect the full agent conversation for debugging
- Batch operations — select multiple tasks and plan/execute/dismiss them at once
- Execution queue — tasks queue up per-project and auto-advance when the previous one finishes
- Cost tracking — per-task and per-project cost breakdowns with budget alerts
- Test framework detection — auto-discovers npm/pytest/cargo/go/make test setups
- Notifications — Slack, Discord, email, webhooks, and browser notifications for task completion, failures, budget alerts, and daily digests
- Plugin system — extend with custom hooks, tools, parsers, and validators (see plugins/README.md)
- Crash recovery — tasks stuck in transient states (executing, planning, queued) are automatically recovered on server restart

Supported AI Models
| Model | Provider | Input / Output Cost |
|---|---|---|
| Claude Opus 4.6 (default) | Claude Code | $15 / $75 per 1M tokens |
| Gemini 3.1 Pro | Gemini CLI | $2.50 / $15 per 1M tokens |
| GPT-5.3 Codex | Codex CLI | $5 / $15 per 1M tokens |
Models are selectable per-task. Generation and planning phases run in read-only mode regardless of model.
