There can only be One File. Map networks, smart homes, sports plays, mind maps, infrastructure or anything with nodes and connections. Animated zones, replay video export, enterprise encryption, full styling. Works offline, opens anywhere, saves into itself.

The Networkening edition adds live status monitoring and icons from selfh.st/icons, MDI, and Simple Icons. Still one file.

*TheOneFile_Verse adds an easily deployable, Docker based, real time collaboration wrapper that enables multiple users to create, edit and share together!

Docker & TheOneFile_Verse

docker run -d -p 10101:10101 -v theonefile-data:/app/data ghcr.io/gelatinescreams/theonefile_verse:latest

Or with docker compose, create a docker-compose.yml:

services:
  theonefile_verse:
    image: ghcr.io/gelatinescreams/theonefile_verse:latest
    ports:
      - "10101:10101"
    volumes:
      - ./data:/app/data
    restart: unless-stopped

Then run:

docker compose up -d

Security & Encryption

Industry Standard Protection:

• AES 256 GCM encryption (authenticated encryption with 256 bit keys)
• PBKDF2 key derivation with:
  • 200,000 iterations (protection against brute force attacks)
  • SHA 256 hashing algorithm
  • Cryptographically secure random 16 byte salt per file
  • Unique 12 byte initialization vector (IV) per encryption
• Browser native Web Crypto API no third party encryption libraries
• Zero server communication all encryption/decryption happens locally in your browser
• Password confirmation required before saving encrypted files
• Non recoverable no backdoors, no password reset, no recovery options
  • If you forget your password, your data is permanently inaccessible
  • This is a feature, not a bug so your data stays protected
• 3 attempt limit on decryption to prevent brute force attempts
• Encrypted data format: Salt + IV + ciphertext embedded directly in the HTML file

Mobile Experience

• Completely rewritten mobile UI in version 3.0
• Resizable mobile footer with drag handle for custom panel sizing
• Touch optimized controls throughout the interface
• Mobile bulk operations modal for efficient multi node editing with Lock and Group buttons
