We created Scorecards to give consumers of open-source projects an easy way to judge whether their dependencies are safe.
Scorecards is an automated tool that assesses a number of important heuristics ("checks") associated with software security and assigns each check a score of 0-10. You can use these scores to understand specific areas to improve in order to strengthen the security posture of your project. You can also assess the risks that dependencies introduce, and make informed decisions about accepting these risks, evaluating alternative solutions, or working with the maintainers to make improvements.
The inspiration for Scorecards’ logo: "You passed! All D's ... and an A!"
-
Automate analysis and trust decisions on the security posture of open source projects.
-
Use this data to proactively improve the security posture of the critical projects the world depends on.
Scorecards has been run on thousands of projects to monitor and track security metrics. Prominent projects that use Scorecards include:
We run a weekly Scorecards scan of the 1 million most critical open source projects judged by their direct dependencies and publish the results in a BigQuery public dataset.
This data is available in the public BigQuery dataset
openssf:scorecardcron.scorecard-v2. The latest results are available in the
BigQuery view openssf:scorecardcron.scorecard-v2_latest.
You can query the data using BigQuery Explorer by navigating to Add Data > Pin a Project > Enter Project Name > 'openssf'
You can extract the latest results to Google Cloud storage in JSON format using
the bq tool:
# Get the latest PARTITION_ID
bq query --nouse_legacy_sql 'SELECT partition_id FROM
openssf.scorecardcron.INFORMATION_SCHEMA.PARTITIONS WHERE table_name="scorecard-v2"
AND partition_id!="__NULL__" ORDER BY partition_id DESC
LIMIT 1'
# Extract to GCS
bq extract --destination_format=NEWLINE_DELIMITED_JSON
'openssf:scorecardcron.scorecard-v2$<partition_id>' gs://bucket-name/filename-*.json
The list of projects that are checked is available in the
cron/data/projects.csv
file in this repository. If you would like us to track more, please feel free to
send a Pull Request with others. Currently, this list is derived from projects
hosted on GitHub ONLY. We do plan to expand them in near future to account for
projects hosted on other source control systems.
The easiest way to use Scorecards on GitHub projects you own is with the Scorecards GitHub Action. The Action runs on any repository change and issues alerts that maintainers can view in the repository’s Security tab. For more information, see the Scorecards GitHub Action installation instructions.
To run a Scorecards scan on projects you do not own, use the command line interface installation option.
Platforms: Currently, Scorecards supports OSX and Linux platforms. If you are using a Windows OS you may experience issues. Contributions towards supporting Windows are welcome.
Language: You must have GoLang installed to run Scorecards (https://golang.org/doc/install)
To install Scorecards as a standalone:
- Visit our latest release page and download the correct binary for your operating system
- Extract the binary file
- Add the binary to your
GOPATH/bindirectory (usego env GOPATHto identify your directory if necessary)
You can use Homebrew (on macOS or Linux) to install Scorecards.
brew install scorecard| Package Manager | Linux Distribution | Command |
|---|---|---|
| Nix | NixOS | nix-shell -p nixpkgs.scorecard |
| AUR helper | Arch Linux | Use your AUR helper to install scorecard |
GitHub imposes api rate limits on unauthenticated requests. To avoid these limits, you must authenticate your requests before running Scorecard. There are two ways to authenticate your requests: either create a GitHub personal access token, or create a GitHub App Installation.
- Create a GitHub personal access token.
When creating the personal access token, we suggest you choose the
public_reposcope. Set the token in an environment variable calledGITHUB_AUTH_TOKEN,GITHUB_TOKEN,GH_AUTH_TOKENorGH_TOKENusing the commands below according to your platform.
# For posix platforms, e.g. linux, mac:
export GITHUB_AUTH_TOKEN=<your access token>
# Multiple tokens can be provided separated by comma to be utilized
# in a round robin fashion.
export GITHUB_AUTH_TOKEN=<your access token1>,<your access token2>
# For windows:
set GITHUB_AUTH_TOKEN=<your access token>
set GITHUB_AUTH_TOKEN=<your access token1>,<your access token2>OR
- Create a GitHub App Installation
for higher rate-limit quotas. If you have an installed GitHub App and key
file, you can use the three environment variables below, following the
commands (
setorexport) shown above for your platform.
GITHUB_APP_KEY_PATH=<path to the key file on disk>
GITHUB_APP_INSTALLATION_ID=<installation id>
GITHUB_APP_ID=<app id>
These variables can be obtained from the GitHub developer settings page.
scorecard is available as a Docker container:
The GITHUB_AUTH_TOKEN has to be set to a valid token
docker run -e GITHUB_AUTH_TOKEN=token gcr.io/openssf/scorecard:stable --show-details --repo=https://github.com/ossf/scorecardTo use a specific scorecards version (e.g., v3.2.1), run:
docker run -e GITHUB_AUTH_TOKEN=token gcr.io/openssf/scorecard:v3.2.1 --show-details --repo=https://github.com/ossf/scorecardScorecards can run using just one argument, the URL of the target repo:
$ scorecard --repo=github.com/ossf-tests/scorecard-check-branch-protection-e2e

Scorecards also produces an aggregate score, which is a weight-based average of the individual checks weighted by risk.
- “Critical” risk checks are weighted at 10
- “High” risk checks are weighted at 7.5
- “Medium” risk checks are weighted at 5
- “Low” risk checks are weighted at 2.5
See the list of current Scorecards checks for each check's risk level.

For projects in the --npm, --pypi, or --rubygems ecosystems, you have the
option to run Scorecards using a package manager. Provide the package name to
run the checks on the corresponding GitHub source code.
For example, --npm=angular.
To run only specific check(s), add the --checks argument with a list of check
names.
For example, --checks=CI-Tests,Code-Review.
There are three formats currently: default, json, and csv. Others may be
added in the future.
These may be specified with the --format flag. For example, --format=json.
If you have what looks like a bug, please use the Github issue tracking system. Before you file an issue, please search existing issues to see if your issue is already covered.
The following checks are all run against the target project by default:
