Quick start

CLI

fairpipe validate \
  --csv data.csv \
  --y-true y_true \
  --y-pred y_pred \
  --sensitive gender \
  --with-ci

fairpipe run-pipeline --config config.yml --csv data.csv --output-dir artifacts/

Python

from fairpipe import load_data
from fairpipe.metrics import FairnessAnalyzer

df = load_data("data.csv")
analyzer = FairnessAnalyzer(min_group_size=30)
result = analyzer.demographic_parity_difference(
    y_pred=df["y_pred"],
    sensitive=df["gender"],
    with_ci=True,
)
print(result.value, result.ci)

CLI commands, YAML configuration, workflow orchestration, training, monitoring, and the optional REST API are documented on the docs site and in docs/api.md.

CI/CD Integration

Add fairness validation to every pull request with the companion GitHub Action:

# .github/workflows/fairness-check.yml
name: Fairness Check
on: [pull_request]

jobs:
  fairness:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: SvrusIO/fairpipe-action@v1
        with:
          csv: data/predictions.csv
          y-true: y_true
          y-pred: y_pred
          sensitive: gender
          threshold: "0.05"
          metric: "equalized_odds_difference"
          fail-on-violation: "true"

Point csv at your predictions file. If equalized odds difference exceeds 0.05, the PR is blocked. A full fairness report is written to the Actions job summary — metric values, confidence intervals, group breakdowns — permanently attached to the commit.
