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

* 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
* : 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| (download) - specifies which ads to download (DEFAULT: new)
Possible values:
* all: downloads all ads from your profile

--ads=changed| (update) - specifies which ads to update (DEFAULT: changed)
Possible values:
* changed: only update ads that have been modified since last publication
* : provide one or several ads by ID to update, like e.g. "--ads=1,2,3"

```
> **Note:** The output of `kleinanzeigen-bot help` is always the most up-to-date reference for available commands and options.
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; `--config` and `--logfile` override only their specific paths, and do not change other mode-dependent paths or the chosen installation mode behavior.
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
When executing the app it by default looks for a `config.yaml` file in the current directory. If it does not exist it will be created automatically.
The configuration file to be used can also be specified using the `--config ` command line parameter. It must point to a YAML or JSON file.
Valid file extensions are `.json`, `.yaml` and `.yml`
The following parameters can be configured:
```yaml
# yaml-language-server: $schema=https://raw.githubusercontent.com/Second-Hand-Friends/kleinanzeigen-bot/refs/heads/main/schemas/config.schema.json
# glob (wildcard) patterns to select ad configuration files
# if relative paths are specified, then they are relative to this configuration file
ad_files:
- "./**/ad_*.{json,yml,yaml}"
# default values for ads, can be overwritten in each ad configuration file
ad_defaults:
active: true

```
Slow networks or sluggish remote browsers often just need a higher `timeouts.multiplier`, while truly problematic selectors can get explicit values directly under `timeouts`.
> **Developer Note:** Remember to regenerate the schemas after changing the configuration model so editors stay in sync.
### Login Detection Behavior
The bot uses a **server-side auth probe** to detect login state more reliably:
1. **Auth probe (primary method)**: Sends a GET request to `{root_url}/m-meine-anzeigen-verwalten.json?sort=DEFAULT`
- Returns `LOGGED_IN` if response is HTTP 200 with valid JSON containing `"ads"` key
- Returns `LOGGED_OUT` if response is HTTP 401/403 or HTML contains login markers
- Returns `UNKNOWN` on timeouts, assertion failures, or unexpected response bodies
2. **DOM fallback**: Only consulted when auth probe returns `UNKNOWN`
- Looks for `.mr-medium` element containing username
- Falls back to `#user-email` ID
- Uses `login_detection` timeout (default: 10.0 seconds)
This approach reduces unnecessary re-login attempts because the server-side probe is not affected by client-side rendering delays (SPA hydration) or A/B test variations, though it may return UNKNOWN and fall back to DOM-based checks.
**⚠️ PII Warning:** HTML dumps may contain your account email or other personally identifiable information. Review files in the diagnostics output directory before sharing them publicly.
**Optional diagnostics** help troubleshoot login detection issues:
- Enable `login_detection_capture` to capture screenshots and HTML dumps when state is `UNKNOWN`
- Enable `pause_on_login_detection_failure` to pause the bot for manual inspection (interactive sessions only; requires `login_detection_capture=true`)
- Use custom `output_dir` to specify where artifacts are saved
**Output locations (default):**
- **Portable mode**: `./.temp/diagnostics/`
- **System-wide mode (XDG)**: `~/.cache/kleinanzeigen-bot/diagnostics/` (Linux) or `~/Library/Caches/kleinanzeigen-bot/diagnostics/` (macOS)
- **Custom**: Path resolved relative to your `config.yaml` if `output_dir` is specified
### 2) Ad configuration
Each ad is described in a separate JSON or YAML file with prefix `ad_`. The prefix is configurable in config file.
Parameter values specified in the `ad_defaults` section of the `config.yaml` file don't need to be specified again in the ad configuration file.
The following parameters can be configured:
```yaml
# yaml-language-server: $schema=https://raw.githubusercontent.com/Second-Hand-Friends/kleinanzeigen-bot/refs/heads/main/schemas/ad.schema.json
active: # true or false (default: true)
type: # one of: OFFER, WANTED (default: OFFER)
title:
description: # can be multiline, see syntax here https://yaml-multiline.info/
description_prefix: # optional prefix to be added to the description overriding the default prefix
description_suffix: # optional suffix to be added to the description overriding the default suffix
# built-in category name as specified in https://github.com/Second-Hand-Friends/kleinanzeigen-bot/blob/main/src/kleinanzeigen_bot/resources/categories.yaml
# or custom category name as specified in config.yaml
# or category ID (e.g. 161/278)
category: # e.g. "Elektronik > Notebooks"
price: # price in euros; decimals allowed but will be rounded to nearest whole euro on processing (prefer whole euros for predictability)
price_type: # one of: FIXED, NEGOTIABLE, GIVE_AWAY (default: NEGOTIABLE)
auto_price_reduction:
enabled: # true or false to enable automatic price reduction on reposts (default: false)
strategy: # "PERCENTAGE" or "FIXED" (required when enabled is true)
amount: # reduction amount; interpreted as percent for PERCENTAGE or currency units for FIXED (prefer whole euros for predictability)
min_price: # required when enabled is true; minimum price floor (use 0 for no lower bound, prefer whole euros for predictability)
delay_reposts: # number of reposts to wait before first reduction (default: 0)
delay_days: # number of days to wait after publication before reductions (default: 0)
# NOTE: All prices are rounded to whole euros after each reduction step.
special_attributes:
# haus_mieten.zimmer_d: value # Zimmer
shipping_type: # one of: PICKUP, SHIPPING, NOT_APPLICABLE (default: SHIPPING)
shipping_costs: # e.g. 2.95 (for individual postage, keep shipping_type SHIPPING and leave shipping_options empty)

contact:
name:
street:
zipcode:
phone: "" # IMPORTANT: surround phone number with quotes to prevent removal of leading zeros
republication_interval: # every X days the ad should be re-published (default: 7)
# The following fields are automatically managed by the bot:
id: # the ID assigned by kleinanzeigen.de
created_on: # ISO timestamp when the ad was first published
updated_on: # ISO timestamp when the ad was last published
content_hash: # hash of the ad content, used to detect changes
repost_count: # how often the ad has been (re)published; used for automatic price reductions
```
#### Automatic price reduction on reposts
When `auto_price_reduction.enabled` is set to `true`, the bot lowers the configured `price` every time the ad is reposted. The starting point for the calculation is always the base price from your ad file (the value of `price`), ensuring the first publication uses the unchanged amount. For each repost the bot subtracts either a percentage of the previously published price (strategy: PERCENTAGE) or a fixed amount (strategy: FIXED) and clamps the result to `min_price`.
**Important:** Price reductions only apply when using the `publish` command (which deletes the old ad and creates a new one). Using the `update` command to modify ad content does NOT trigger price reductions or increment `repost_count`.
`repost_count` is tracked for every ad (and persisted inside the corresponding `ad_*.yaml`) so reductions continue across runs.
`min_price` is required whenever `enabled` is `true` and must be less than or equal to `price`; this makes an explicit floor (including `0`) mandatory. If `min_price` equals the current price, the bot will log a warning and perform no reduction.
**Note:** `repost_count` and price reduction counters are only incremented and persisted after a successful publish. Failed publish attempts do not advance the counters.
**PERCENTAGE strategy example:**
```yaml
price: 150
price_type: FIXED
auto_price_reduction:
enabled: true
strategy: PERCENTAGE
amount: 10
min_price: 90
delay_reposts: 0
delay_days: 0
```
This posts the ad at 150 € the first time, then 135 € (−10%), 122 € (−10%), 110 € (−10%), 99 € (−10%), and stops decreasing at 90 €.
**Note:** The bot applies commercial rounding (ROUND_HALF_UP) to full euros after each reduction step. For example, 121.5 rounds to 122, and 109.8 rounds to 110. This step-wise rounding affects the final price progression, especially for percentage-based reductions.
**FIXED strategy example:**
```yaml
price: 150
price_type: FIXED
auto_price_reduction:
enabled: true
strategy: FIXED
amount: 15
min_price: 90
delay_reposts: 0
delay_days: 0
```
This posts the ad at 150 € the first time, then 135 € (−15 €), 120 € (−15 €), 105 € (−15 €), and stops decreasing at 90 €.
**Note on `delay_days` behavior:** The `delay_days` parameter counts complete 24-hour periods (whole days) since the ad was published. For example, if `delay_days: 7` and the ad was published 6 days and 23 hours ago, the reduction will not yet apply. This ensures predictable behavior and avoids partial-day ambiguity.
Set `auto_price_reduction.enabled: false` (or omit the entire `auto_price_reduction` section) to keep the existing behaviour—prices stay fixed and `repost_count` only acts as tracked metadata for future changes.
You can configure `auto_price_reduction` once under `ad_defaults` in `config.yaml`. The `min_price` can be set there or overridden per ad file as needed.
### 3) Description Prefix and Suffix
You can add prefix and suffix text to your ad descriptions in two ways:
#### New Format (Recommended)
In your config.yaml file you can specify a `description_prefix` and `description_suffix` under the `ad_defaults` section.
```yaml
ad_defaults:
description_prefix: "Prefix text"
description_suffix: "Suffix text"
```
#### Legacy Format
In your ad configuration file you can specify a `description_prefix` and `description_suffix` under the `description` section.
```yaml
description:
prefix: "Prefix text"
suffix: "Suffix text"
```
#### Precedence
The new format has precedence over the legacy format. If you specify both the new and the legacy format in your config, the new format will be used. We recommend using the new format as it is more flexible and easier to manage.
### 4) Using an existing browser window
By default a new browser process will be launched. To reuse a manually launched browser window/process follow these steps:
1. Manually launch your browser from the command line with the `--remote-debugging-port=` flag.
You are free to choose an unused port number 1025 and 65535, e.g.:
- `chrome --remote-debugging-port=9222`
- `chromium --remote-debugging-port=9222`
- `msedge --remote-debugging-port=9222`
This runs the browser in debug mode which allows it to be remote controlled by the bot.
**⚠️ IMPORTANT: Chrome 136+ Security Requirement**
Starting with Chrome 136 (March 2025), Google has implemented security changes that require `--user-data-dir` to be specified when using `--remote-debugging-port`. This prevents attackers from accessing the default Chrome profile and stealing cookies/credentials.
**You must now use:**
```bash
chrome --remote-debugging-port=9222 --user-data-dir=/path/to/custom/directory
```
**And in your config.yaml:**
```yaml
browser:
arguments:
- --remote-debugging-port=9222
- --user-data-dir=/path/to/custom/directory
user_data_dir: "/path/to/custom/directory"
```
**The bot will automatically detect Chrome 136+ and validate your configuration. If validation fails, you'll see clear error messages with specific instructions on how to fix your configuration.**
1. In your config.yaml specify the same flags as browser arguments, e.g.:
```yaml
browser:
arguments:
- --remote-debugging-port=9222
- --user-data-dir=/tmp/chrome-debug-profile # Required for Chrome 136+
user_data_dir: "/tmp/chrome-debug-profile" # Must match the argument above
```
1. When now publishing ads the manually launched browser will be re-used.
> NOTE: If an existing browser is used all other settings configured under `browser` in your config.yaml file will ignored
because they are only used to programmatically configure/launch a dedicated browser instance.
> **Security Note:** This change was implemented by Google to protect users from cookie theft attacks. The custom user data directory uses a different encryption key than the default profile, making it more secure for debugging purposes.
### Browser Connection Issues
If you encounter browser connection problems, the bot includes a diagnostic command to help identify issues:
**For binary users:**
```bash
kleinanzeigen-bot diagnose
```
**For source users:**
```bash
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](docs/BROWSER_TROUBLESHOOTING.md).
