You can run Presenton in two ways: Docker for a one-command setup without installing a local dev stack, or the Electron desktop app for a native app experience (ideal for development or offline use).

Option 1: Electron (Desktop App)

Run Presenton as a native desktop application. LLM and image provider (API keys, etc.) can be configured in the app. The same environment variables used for Docker apply when running the bundled backend.

Prerequisites: Node.js (LTS), npm, Python 3.11, and uv (for the Electron FastAPI backend in electron/servers/fastapi).

• Setup (First Time)

  cd electron
  npm run setup:env

  This installs Node dependencies, runs uv sync in the FastAPI server, and installs Next.js dependencies.

• Run in Development

  npm run dev

  This compiles TypeScript and starts Electron. The backend and UI run locally inside the desktop window.

• Build Distributable (Optional) To create installers for Windows, macOS, or Linux:

  npm run build:all
  npm run dist

  Output files are written to electron/dist (or as configured in your electron-builder settings).

Option 2: Docker

• Start Presenton Linux/MacOS (Bash/Zsh Shell):

  docker run -it --name presenton -p 5000:80 -v "./app_data:/app_data" ghcr.io/presenton/presenton:latest

  Windows (PowerShell):

  docker run -it --name presenton -p 5000:80 -v "${PWD}\app_data:/app_data" ghcr.io/presenton/presenton:latest

• Open Presenton

  Open http://localhost:5000 in the browser of your choice to use Presenton.

  Note: You can replace 5000 with any other port number of your choice to run Presenton on a different port number.

These settings apply to both Docker and the Electron app's backend. You may want to directly provide your API KEYS as environment variables and keep them hidden. You can set these environment variables to achieve it.

• CAN_CHANGE_KEYS=[true/false]: Set this to false if you want to keep API Keys hidden and make them unmodifiable.
• LLM=[openai/google/anthropic/ollama/custom]: Select LLM of your choice.
• OPENAI_API_KEY=[Your OpenAI API Key]: Provide this if LLM is set to openai
• OPENAI_MODEL=[OpenAI Model ID]: Provide this if LLM is set to openai (default: "gpt-4.1")
• GOOGLE_API_KEY=[Your Google API Key]: Provide this if LLM is set to google
• GOOGLE_MODEL=[Google Model ID]: Provide this if LLM is set to google (default: "models/gemini-2.0-flash")
• ANTHROPIC_API_KEY=[Your Anthropic API Key]: Provide this if LLM is set to anthropic
• ANTHROPIC_MODEL=[Anthropic Model ID]: Provide this if LLM is set to anthropic (default: "claude-3-5-sonnet-20241022")
• OLLAMA_URL=[Custom Ollama URL]: Provide this if you want to custom Ollama URL and LLM is set to ollama
• OLLAMA_MODEL=[Ollama Model ID]: Provide this if LLM is set to ollama
• CUSTOM_LLM_URL=[Custom OpenAI Compatible URL]: Provide this if LLM is set to custom
• CUSTOM_LLM_API_KEY=[Custom OpenAI Compatible API KEY]: Provide this if LLM is set to custom
• CUSTOM_MODEL=[Custom Model ID]: Provide this if LLM is set to custom
• TOOL_CALLS=[Enable/Disable Tool Calls on Custom LLM]: If true, LLM will use Tool Call instead of Json Schema for Structured Output.
• DISABLE_THINKING=[Enable/Disable Thinking on Custom LLM]: If true, Thinking will be disabled.
• WEB_GROUNDING=[Enable/Disable Web Search for OpenAI, Google And Anthropic]: If true, LLM will be able to search web for better results.

You can also set the following environment variables to customize the image generation provider and API keys:

• DISABLE_IMAGE_GENERATION: If true, Image Generation will be disabled for slides.
• IMAGE_PROVIDER=[dall-e-3/gpt-image-1.5/gemini_flash/nanobanana_pro/pexels/pixabay/comfyui]: Select the image provider of your choice.
  • Required if DISABLE_IMAGE_GENERATION is not set to true.
• OPENAI_API_KEY=[Your OpenAI API Key]: Required if using dall-e-3 or gpt-image-1.5 as the image provider.
• DALL_E_3_QUALITY=[standard/hd]: Optional quality setting for dall-e-3 (default: standard).
• GPT_IMAGE_1_5_QUALITY=[low/medium/high]: Optional quality setting for gpt-image-1.5 (default: medium).
• GOOGLE_API_KEY=[Your Google API Key]: Required if using gemini_flash or nanobanana_pro as the image provider.
• PEXELS_API_KEY=[Your Pexels API Key]: Required if using pexels as the image provider.
• PIXABAY_API_KEY=[Your Pixabay API Key]: Required if using pixabay as the image provider.
• COMFYUI_URL=[Your ComfyUI server URL] and COMFYUI_WORKFLOW=[Workflow JSON]: Required if using comfyui to route prompts to a self-hosted ComfyUI workflow.

You can disable anonymous telemetry using the following environment variable:

• DISABLE_ANONYMOUS_TELEMETRY=[true/false]: Set this to true to disable anonymous telemetry.

Note: You can freely choose both the LLM (text generation) and the image provider. Supported image providers: dall-e-3, gpt-image-1.5 (OpenAI), gemini_flash, nanobanana_pro (Google), pexels, pixabay, and comfyui (self-hosted).

Docker Run Examples by Provider

• Running Presenton with GPU Support

  To use GPU acceleration with Ollama models, you need to install and configure the NVIDIA Container Toolkit. This allows Docker containers to access your NVIDIA GPU.

  Once the NVIDIA Container Toolkit is installed and configured, you can run Presenton with GPU support by adding the --gpus=all flag:

  docker run -it --name presenton --gpus=all -p 5000:80 -e LLM="ollama" -e OLLAMA_MODEL="llama3.2:3b" -e IMAGE_PROVIDER="pexels" -e PEXELS_API_KEY="*******" -e CAN_CHANGE_KEYS="false" -v "./app_data:/app_data" ghcr.io/presenton/presenton:latest
