A local-first desktop application for creating, executing, and deploying AI workflows. Build composable prompts with visual editing, a professional code editor, and package-based inheritance.
Prompd brings software engineering practices to AI prompt development. Instead of managing prompts as loose text files, Prompd treats them as structured, versioned, composable documents with typed parameters, inheritance, and dependency management.
Everything runs locally. Your API keys, prompts, and data never leave your machine. LLM calls go directly from Prompd to provider APIs with zero intermediaries.
Platform: Pre-built binaries are currently Windows only. Mac and Linux builds are coming soon. You can build from source on any platform today.

- Visual Workflow Canvas - Drag-and-drop editor with 27 node types: prompts, agents, parallel execution, loops, conditionals, error handling, database queries, MCP tools, and more
- Dual Code/Design View - Switch between a WYSIWYG design editor and Monaco code editor with IntelliSense, syntax highlighting, and package completions
- 10 LLM Providers - OpenAI, Anthropic, Google Gemini, Groq, Mistral, Cohere, Together AI, Perplexity, DeepSeek, and local Ollama — plus any OpenAI-compatible endpoint
- Package Inheritance - Prompts can inherit from and extend other prompts, just like classes in software:
inherits: "@prompd/core@1.0.0/prompts/base.prmd" - Execution History - Track every run with cost tracking, success rates, timing, and full input/output history
- MCP Integration - Connect to Model Context Protocol servers for tool discovery and execution
- Workflow Deployment - Package and deploy workflows as persistent background services with cron scheduling and webhook triggers
- Registry - Search, install, and publish prompt packages via PrompdHub
- Offline Support - Full functionality without internet after initial setup
- Database Nodes - Query MongoDB, PostgreSQL, MySQL, SQLite, and Redis directly from workflows

Prerequisites: Node.js 18+
# Clone the repository
git clone https://github.com/Prompd/prompd-app.git
cd prompd-app
# Build local packages (required before frontend)
cd packages/scheduler && npm install && npm run build
cd ../react && npm install && npm run build
# Launch the desktop app
cd ../../frontend && npm install
npm run electron:devThe app opens with a setup wizard that walks you through configuring your first API key and creating a prompt.
| Extension | Description | Structure |
|---|---|---|
.prmd |
Prompt files | YAML frontmatter + Markdown body |
.pdflow |
Workflow definitions | YAML with visual node/edge data |
.pdpkg |
Package archives | ZIP bundles with manifest.json |
All file references (inherits:, context:, {% include %}) resolve relative to the containing file's directory.
| Component | Technology |
|---|---|
| Frontend | React 18 + TypeScript + Vite |
| Desktop | Electron 40 |
| State | Zustand with Immer |
| Code Editor | Monaco Editor |
| Workflow Canvas | XYFlow (React Flow) |
| Prompt Compiler | @prompd/cli |
| Backend (optional) | Node.js + Express + MongoDB |
User Action -> Electron IPC -> Local Execution
-> Direct HTTPS to LLM APIs
-> @prompd/cli for compilation
-> SQLite for deployment state
The backend API is optional and only used for provider/model list updates, registry package search, and cloud sync features. All core operations (compilation, execution, file management, scheduling) run entirely in the Electron main process.
