OpenDoor OWASP is a multifunctional console website scanner.
This application finds possible login entry points, Index of/ directories, web shells, restricted access points, subdomains, hidden data, and large backup files.
Scanning is performed using both the built-in dictionary and external dictionaries.
Anonymity and speed are provided through the use of proxy servers.
The software is written for informational purposes and is released as an open-source product under the GPL license.
The project is part of BlackArch Linux and is maintained and supported by the community.

• Built-in dictionaries
  • Directories: 115092
  • Subdomains: 1507134

v5.11.0 (28.04.2026)

• (feature) added smart auto-calibration via --auto-calibrate
• (feature) added baseline filtering for soft-404, wildcard and catch-all responses
• (feature) added --calibration-samples to control the number of random calibration probes
• (feature) added --calibration-threshold to control calibration match strictness
• (feature) added multi-signal calibration signatures based on status code, OpenDoor bucket, normalized body hash, HTML skeleton hash, title, redirect target, stable headers, size, word count and line count
• (feature) added calibrated result bucket for responses filtered by auto-calibration
• (enhancement) auto-calibration remains strict opt-in and does not change default scan behaviour when disabled
• (enhancement) auto-calibration forces HEAD to GET only when enabled because response body analysis is required
• (enhancement) dynamic response fragments such as UUIDs, timestamps, long numeric IDs, nonce and CSRF-like values are normalized before hashing
• (enhancement) calibration matches now preserve calibration_score and calibration_reason in detailed report items
• (enhancement) calibration baseline is persisted in session checkpoints and restored on resume
• (enhancement) auto-calibration options are preserved for wizard and session resume flows
• (enhancement) blocked WAF probe responses are skipped during calibration baseline creation
• (enhancement) failed calibration probes no longer stop the scan; OpenDoor safely continues without a usable baseline
• (enhancement) CI/CD --fail-on-bucket remains compatible with auto-calibration and can explicitly target the calibrated bucket
• (tests) added unittest coverage for calibration signatures, normalization, scoring, matching and fallback paths
• (tests) added regression coverage for Browser calibration runtime, session persistence and controller orchestration
• (tests) full unittest suite passes after integration (999 tests)
• (tests) coverage gate passes at 98%

Install PIP

python3 -m ensurepip --upgrade
python3 -m pip install --upgrade pip

Global installation from PyPI

Use this if you want the package available as a normal Python CLI tool.

Linux / macOS

python3 -m pip install --upgrade opendoor
opendoor --host http://www.example.com

Windows (PowerShell)

winget install Python.Python.3.14
py -m pip install --upgrade pip
py -m pip install --upgrade opendoor

opendoor --host http://www.example.com

Global installation with pipx (recommended for end users)

macOS / Homebrew

brew install pipx
pipx ensurepath
pipx install opendoor

opendoor --host http://www.example.com

Linux / generic environments

Install pipx with your system package manager or preferred Python tooling, then:

pipx ensurepath
pipx install opendoor

opendoor --host http://www.example.com

Windows (PowerShell)

winget install Python.Python.3.14
py -m pip install --user pipx
py -m pipx ensurepath

# Reopen PowerShell after ensurepath
pipx install opendoor

opendoor --host http://www.example.com

pipx is the preferred option when you want an isolated CLI installation without managing a project virtual environment manually.

Local installation and run

Use this mode if you want to run OpenDoor directly from the repository without installing it globally.

Linux / macOS

git clone https://github.com/stanislav-web/OpenDoor.git
cd OpenDoor/
python3 -m pip install -r requirements.txt
chmod +x opendoor.py

python3 opendoor.py --host http://www.example.com

Windows (PowerShell)

git clone https://github.com/stanislav-web/OpenDoor.git
cd OpenDoor
py -m pip install -r requirements.txt

py opendoor.py --host http://www.example.com

Local development installation

Use this mode if you are developing, testing, or changing the project locally.

Linux / macOS

git clone https://github.com/stanislav-web/OpenDoor.git
cd OpenDoor/
python3 -m venv .venv
source .venv/bin/activate
python -m pip install --upgrade pip setuptools wheel
python -m pip install -r requirements-dev.txt
python -m pip install -e .

opendoor --host http://www.example.com

Windows (PowerShell)

git clone https://github.com/stanislav-web/OpenDoor.git
cd OpenDoor
py -m venv .venv
.\.venv\Scripts\Activate.ps1
python -m pip install --upgrade pip setuptools wheel
python -m pip install -r requirements-dev.txt
python -m pip install -e .

opendoor --host http://www.example.com

Installation from source for OS distributions / maintainers

This flow is intended for Linux distributions, package maintainers, and release pipelines.

Linux / macOS

git clone https://github.com/stanislav-web/OpenDoor.git
cd OpenDoor/
python3 -m pip install --upgrade build
python3 -m build

Windows (PowerShell)

git clone https://github.com/stanislav-web/OpenDoor.git
cd OpenDoor
py -m pip install --upgrade build
py -m build

This flow is preferable for Linux distributions and package maintainers because:

• source package and wheel are generated through the standard Python build backend
• installation can be managed by the distribution package manager
• updates can be delivered together with OS package updates
• no legacy setup.py install flow is required

The package is already present in BlackArch Linux, and this build layout is intended to make packaging for other Linux distributions easier as well.

PyPI installation

Linux / macOS:

python3 -m pip install --upgrade opendoor

Windows:

py -m pip install --upgrade opendoor

pipx installation

pipx upgrade opendoor

Source checkout

Linux / macOS:

git pull
python3 -m pip install -e .

Windows:

git pull
py -m pip install -e .
