Presenton Cloud

⚡ Running Presenton

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 shared FastAPI backend in 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 5001:80 -v "./app_data:/app_data" ghcr.io/presenton/presenton:latest

    Windows (PowerShell):

    docker run -it --name presenton -p 5001:80 -v "${PWD}\app_data:/app_data" ghcr.io/presenton/presenton:latest
  • Open Presenton

    Open http://localhost:5001 in the browser of your choice to use Presenton.

    Note: You can replace 5001 with any other port number of your choice to run Presenton on a different port number. If you use Docker Compose, set PRESENTON_HTTP_HOST_PORT, for example PRESENTON_HTTP_HOST_PORT=8080 docker compose up production.

⚙️ Deployment Configurations

The lists below match the environment variables forwarded in this repository’s docker-compose.yml (production, production-gpu, development, and development-gpu). Put values in a .env file next to the compose file, or export them before docker compose up. The Electron app backend can read the same names when run outside Docker.

Other optional variables exist in code (for example advanced Mem0 paths, LiteParse runners, or FAST_API_INTERNAL_URL when Next.js and FastAPI are not same-origin); they are not wired in docker-compose.yml. Supported names are discoverable from servers/fastapi/utils/get_env.py and the Next.js server utilities under servers/nextjs/.

  • OLLAMA_MODEL: Model name in Ollama (e.g. llama3.2:3b).
  • START_OLLAMA=[true/false]: Container entrypoint (start.js): optional install + ollama serve. Default false (development / production compose).

Presentation memory (Mem0 OSS)

Mem0 uses local Qdrant + SQLite (OSS); memory is scoped per presentation.

By default the Docker runtime now points Mem0 at a local Ollama-compatible LLM endpoint, so it no longer needs an OpenAI key just to initialize. If you want to use OpenAI instead, set MEM0_LLM_BASE_URL/MEM0_LLM_API_KEY to your OpenAI-compatible endpoint and key. Docker images install the default spaCy model (en_core_web_sm) during build so Mem0 can start without extra setup on each run.

VariablePurpose
MEM0_ENABLEDtrue/false (compose default true).
MEM0_LLM_MODELMem0 LLM model name (compose default llama3.1:latest or OLLAMA_MODEL).
MEM0_LLM_API_KEYMem0 LLM API key placeholder for OpenAI-compatible clients (compose default ollama).
MEM0_LLM_BASE_URLMem0 LLM base URL (compose default OLLAMA_URL or http://host.docker.internal:11434).
MEM0_DIRRoot directory (compose default /app_data/mem0).
MEM0_EMBEDDER_PROVIDEREmbedder backend (compose default fastembed).
MEM0_EMBEDDER_MODELModel id (compose default BAAI/bge-small-en-v1.5).
MEM0_EMBEDDING_DIMSVector size (compose default 384).
MEM0_SPACY_MODELOptional spaCy model override (default en_core_web_sm).
MEM0_REQUIRE_SPACY_MODELKeep as true (default). Set to false only if you intentionally want Mem0 to run without spaCy lemmatization.

Document parsing (LiteParse)

VariablePurpose
LITEPARSE_DPIOCR render DPI (compose default 120).
LITEPARSE_NUM_WORKERSWorker count (compose default 1).

Database

  • DATABASE_URL: SQLAlchemy URL; if unset, the app falls back to SQLite under app data.
  • MIGRATE_DATABASE_ON_STARTUP: Compose sets true for all services so migrations run on startup.

Image generation

These variables match docker-compose.yml. IMAGE_PROVIDER selects the backend (pexels, pixabay, gemini_flash, nanobanana_pro, dall-e-3, gpt-image-1.5, comfyui, open_webui). Use OPENAI_API_KEY for OpenAI image modes and GOOGLE_API_KEY for Gemini image modes (same keys as the LLM section).

  • DISABLE_IMAGE_GENERATION=[true/false]: Disable slide image generation.
  • IMAGE_PROVIDER: Provider id (see enum above).
  • PEXELS_API_KEY: Pexels stock images.
  • PIXABAY_API_KEY: Pixabay stock images.
  • DALL_E_3_QUALITY=[standard/hd]: Optional for dall-e-3 (default standard).
  • GPT_IMAGE_1_5_QUALITY=[low/medium/high]: Optional for gpt-image-1.5 (default medium).
  • COMFYUI_URL / COMFYUI_WORKFLOW: Self-hosted ComfyUI workflow JSON.
  • OPEN_WEBUI_IMAGE_URL / OPEN_WEBUI_IMAGE_API_KEY: Open WebUI–compatible image endpoint.
  • OPENAI_COMPAT_IMAGE_BASE_URL / OPENAI_COMPAT_IMAGE_API_KEY / OPENAI_COMPAT_IMAGE_MODEL: Required if using openai_compatible to send image requests to any OpenAI-compatible /v1/images/* endpoint (LiteLLM, Azure, vLLM Gateways, etc.).

Telemetry

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

Authentication (web login)

Presenton uses a single admin account per instance. Credentials live in app_data (hashed; see userConfig.json). Pass these with -e or via .env for compose:

  • AUTH_USERNAME / AUTH_PASSWORD — Preseed the admin login on first boot (password at least 6 characters). Ignored if a user already exists unless AUTH_OVERRIDE_FROM_ENV is set.
  • AUTH_OVERRIDE_FROM_ENV=[true/false] — If true, replace stored credentials from the env vars on every FastAPI startup and rotate the session signing secret (invalidates existing sessions). Remove after a one-off rotation.
  • RESET_AUTH=[true/false] — If true, clear stored credentials on startup. Use for a single boot to recover access, then unset.

Examples

docker run -it --name presenton -p 5001:80 -v "./app_data:/app_data" ghcr.io/presenton/presenton:latest
docker run -it --name presenton -p 5001:80 -e AUTH_USERNAME=admin -e AUTH_PASSWORD=changeme123 -v "./app_data:/app_data" ghcr.io/presenton/presenton:latest
docker run -it --name presenton -p 5001:80 -e AUTH_USERNAME=admin -e AUTH_PASSWORD=changeme123 -v "${PWD}\app_data:/app_data" ghcr.io/presenton/presenton:latest
docker stop presenton && docker rm presenton && docker run -it --name presenton -p 5001:80 -e AUTH_USERNAME=admin -e AUTH_PASSWORD=newcred456 -e AUTH_OVERRIDE_FROM_ENV=true -v "./app_data:/app_data" ghcr.io/presenton/presenton:latest
docker stop presenton && docker rm presenton && docker run -it --name presenton -p 5001:80 -e RESET_AUTH=true -v "./app_data:/app_data" ghcr.io/presenton/presenton:latest
docker stop presenton && docker rm presenton && docker run -it --name presenton -p 5001:80 -e AUTH_USERNAME=admin -e AUTH_PASSWORD=changeme123 -v "./app_data:/app_data" ghcr.io/presenton/presenton:latest

Manual reset: stop the container, edit ./app_data/userConfig.json, delete AUTH_USERNAME, AUTH_PASSWORD_HASH, and AUTH_SECRET_KEY, save, and start again.

Sign out from the app: Settings → Other → Sign out.

MCP authentication

When auth is configured (AUTH_USERNAME / AUTH_PASSWORD), the MCP endpoint at /mcp now requires authentication as well.

  1. Log in once to get a bearer token:
curl -s -X POST http://localhost:5001/api/v1/auth/login \
  -H "Content-Type: application/json" \
  -d '{"username":"admin","password":"changeme123"}'

The response includes:

  • access_token (session token)
  • token_type (bearer)
  1. Configure your MCP client to send that token on every request:
{
  "mcpServers": {
    "presenton": {
      "url": "http://localhost:5001/mcp",
      "headers": {
        "Authorization": "Bearer <access_token>"
      }
    }
  }
}

Notes:

  • If you rotate credentials with AUTH_OVERRIDE_FROM_ENV=true, previously issued session tokens are invalidated.
  • MCP is not available in the Electron desktop app (PRESENTON_ELECTRON=true). Electron runs with DISABLE_AUTH=true by default, and the MCP server is disabled there to avoid auth conflicts.

Note: LLM and image variables above are forwarded from docker-compose.yml when set in .env.

  • 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 5001:80 -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
  • Using an OpenAI-Compatible Image Provider

    This routes all slide image requests through your OpenAI-compatible gateway (LiteLLM, Azure, vLLM, etc.) while keeping the text LLM configuration independent:

    docker run -it --name presenton -p 5001:80 -e IMAGE_PROVIDER="openai_compatible" -e OPENAI_COMPAT_IMAGE_BASE_URL="https://proxy.example.com/v1" -e OPENAI_COMPAT_IMAGE_API_KEY="******" -e OPENAI_COMPAT_IMAGE_MODEL="gpt-image-1" -v "./app_data:/app_data" ghcr.io/presenton/presenton:latest
