Doorstop is a requirements management tool that facilitates the storage of textual requirements alongside source code in version control.

When a project leverages this tool, each linkable item (requirement, test case, etc.) is stored as a YAML file in a designated directory. The items in each directory form a document. The relationship between documents forms a tree hierarchy. Doorstop provides mechanisms for modifying this tree, validating item traceability, and publishing documents in several formats.

Doorstop is under active development and we welcome contributions. The project is licensed as LGPLv3. To report a problem or a security vulnerability please raise an issue. Additional references:



  • Python 3.9+
  • A version control system for requirements storage


Install Doorstop with pip:

$ pip install doorstop

or add it to your Poetry project:

$ poetry add doorstop

After installation, Doorstop is available on the command-line:

$ doorstop --help

And the package is available under the name 'doorstop':

$ python
>>> import doorstop
>>> doorstop.__version__


Switch to an existing version control working directory, or create one:

$ git init .

Create documents

Create a new parent requirements document:

$ doorstop create SRD ./reqs/srd

Add a few items to that document:

$ doorstop add SRD
$ doorstop add SRD
$ doorstop add SRD

Create a child document to link to the parent:

$ doorstop create HLTC ./tests/hl --parent SRD
$ doorstop add HLTC

Link items between documents:

$ doorstop link HLTC001 SRD002

Publish reports

Run integrity checks on the document tree:

$ doorstop

Publish the documents as HTML:

$ doorstop publish all ./public
