Usage

Usage: kleinanzeigen-bot COMMAND [OPTIONS]

Commands:
  publish  - (re-)publishes ads
  verify   - verifies the configuration files
  delete   - deletes ads
  update   - updates published ads
  download - downloads one or multiple ads
  extend   - extends active ads that expire soon (keeps watchers/savers and does not count towards the monthly ad quota)
  update-check - checks for available updates
  update-content-hash – recalculates each ad's content_hash based on the current ad_defaults;
                      use this after changing config.yaml/ad_defaults to avoid every ad being marked "changed" and republished
  create-config - creates a new default configuration file if one does not exist
  diagnose - diagnoses browser connection issues and shows troubleshooting information
  --
  help     - displays this help (default command)
  version  - displays the application version

Options:
  --ads=all|due|new|changed|<id(s)> (publish) - specifies which ads to (re-)publish (DEFAULT: due)
        Possible values:
        * all: (re-)publish all ads ignoring republication_interval
        * due: publish all new ads and republish ads according the republication_interval
        * new: only publish new ads (i.e. ads that have no id in the config file)
        * changed: only publish ads that have been modified since last publication
        * <id(s)>: provide one or several ads by ID to (re-)publish, like e.g. "--ads=1,2,3" ignoring republication_interval
        * Combinations: You can combine multiple selectors with commas, e.g. "--ads=changed,due" to publish both changed and due ads
  --ads=all|new|<id(s)> (download) - specifies which ads to download (DEFAULT: new)
        Possible values:
        * all: downloads all ads from your profile

Limitation of download: It's only possible to extract the cheapest given shipping option.

Configuration

All configuration files can be in YAML or JSON format.

Installation modes (portable vs. system-wide)

On first run, the app may ask which installation mode to use. In non-interactive environments (CI/headless), it defaults to portable mode and will not prompt.

The --config and --logfile flags override only their specific paths. They do not change the chosen installation mode or other mode-dependent paths (downloads, state files, etc.).

1. Portable mode (recommended for most users, especially on Windows):

   • Stores config, logs, downloads, and state in the current directory
   • No admin permissions required
   • Easy backup/migration; works from USB drives

2. System-wide mode (advanced users / multi-user setups):

   • Stores files in OS-standard locations
   • Cleaner directory structure; better separation from working directory
   • Requires proper permissions for user data directories

OS notes (brief):

• Windows: System-wide uses AppData (Roaming/Local); portable keeps everything beside the .exe.
• Linux: System-wide follows XDG Base Directory spec; portable stays in the current working directory.
• macOS: System-wide uses ~/Library/Application Support/kleinanzeigen-bot (and related dirs); portable stays in the current directory.

1) Main configuration ⚙️

The main configuration file (config.yaml) is required to run the bot. It contains your login credentials and controls all bot behavior.

Quick start:

# Generate a config file with all defaults
kleinanzeigen-bot create-config

# Or specify a custom location
kleinanzeigen-bot --config /path/to/config.yaml publish

Minimal config.yaml:

# yaml-language-server: $schema=https://raw.githubusercontent.com/Second-Hand-Friends/kleinanzeigen-bot/main/schemas/config.schema.json
login:
  username: "your_username"
  password: "your_password"

📖 Complete Configuration Reference →

Full documentation including timeout tuning, browser settings, ad defaults, diagnostics, and all available options.

2) Ad configuration 📝

Each ad is defined in a separate YAML/JSON file (default pattern: ad_*.yaml). These files specify the title, description, price, category, images, and other ad-specific settings.

Quick example (ad_laptop.yaml):

# yaml-language-server: $schema=https://raw.githubusercontent.com/Second-Hand-Friends/kleinanzeigen-bot/main/schemas/ad.schema.json
active: true
title: "Gaming Laptop - RTX 3060"
description: |
  Powerful gaming laptop in excellent condition.
  Includes original box and charger.
category: "Elektronik > Notebooks"
price: 450
price_type: NEGOTIABLE
images:
  - "laptop/*.jpg"  # Relative to ad file location (or use absolute paths); glob patterns supported

📖 Complete Ad Configuration Reference →

Full documentation including automatic price reduction, shipping options, category IDs, and special attributes.

3) Using an existing browser window (Optional)

By default a new browser process will be launched. To reuse a manually launched browser window/process, you can enable remote debugging. This is useful for debugging or when you want to keep your browser session open.

For detailed instructions on setting up remote debugging with Chrome 136+ security requirements, see Browser Troubleshooting - Using an Existing Browser Window.

Browser Connection Issues

If you encounter browser connection problems, the bot includes a diagnostic command to help identify issues:

For binary users:

kleinanzeigen-bot diagnose

For source users:

pdm run app diagnose

This command will check your browser setup and provide troubleshooting information. For detailed solutions to common browser connection issues, see the Browser Connection Troubleshooting Guide.
