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.

Changelog (last changes)

v5.7.0 (22.04.2026)

• (feature) Added --fingerprint to run heuristic technology fingerprinting before the main scan.
• (feature) Added probable application stack detection for popular CMS, ecommerce platforms, frameworks, site builders, and static-site tooling.
• (feature) Added infrastructure fingerprinting for AWS (CloudFront, S3, ELB/ALB, API Gateway, Amplify), Cloudflare, Vercel, Netlify, GitHub Pages, GitLab Pages, Heroku, Azure, Google Cloud, Fastly, Akamai, and OpenResty.
• (feature) Added fingerprint summary fields to the standard report output, including application category/name/confidence and infrastructure provider/confidence.
• (ux) Fingerprinting now runs after connectivity checks and before the main scan without breaking the existing scan pipeline.
• (tests) Added regression coverage for fingerprint detection rules, runtime browser integration, controller orchestration, and report rendering.
• (tests) Full unittest suite passes after integration (679 tests).

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 .
