PixelCI

Appearance

Getting Started ​

PixelCI is a self-hosted visual regression testing platform. It compares screenshots from your CI/CD pipeline against approved baselines and flags visual changes for review.

How It Works ​

  1. Upload Screenshots — your CI pipeline uploads screenshots after each build
  2. Automatic Comparison — PixelCI compares them against approved baselines
  3. Smart Analysis — matches against previously approved changes across branches
  4. Review & Approve — team members review changes in the web UI
  5. Build Status — CI passes if all changes are approved, fails if review is needed

Quick Start ​

1. Deploy PixelCI ​

Run the server with Docker:

bash
docker run -d \
  --name pixelci \
  -p 7924:7924 \
  -e APP_ENV=production \
  -e ENABLE_JOB_RUNNER=true \
  -e AUTH_JWT_SECRET=your-secret-key \
  -e REDIS_HOST=redis \
  -e REDIS_PREFIX=pixelci \
  -e MYSQL_HOST=mysql \
  -e MYSQL_USER=root \
  -e MYSQL_PASSWORD_SECRET=your-password \
  -e MYSQL_DATABASE=pixelci \
  -e S3_ENDPOINT=https://s3.amazonaws.com \
  -e S3_REGION=us-east-1 \
  -e S3_ACCESS_KEY_ID=your-access-key \
  -e S3_ACCESS_SECRET=your-secret-key \
  -e S3_BUCKET=pixelci \
  ghcr.io/zyno-io/pixelci:latest

Then run migrations:

bash
docker exec pixelci node . migrate:run

See the Deployment Guide for Docker Compose, Kubernetes, and full configuration reference.

2. Set Up Authentication ​

PixelCI uses GitLab OAuth for authentication. See the GitLab Setup Guide to configure OAuth and create your first app.

3. Add to Your CI Pipeline ​

yaml
visual-regression:
    stage: test
    image: ghcr.io/zyno-io/pixelci/cli:latest
    variables:
        PIXELCI_API_URL: https://pixelci.example.com
    script:
        - pixelci ./screenshots

See the GitLab Setup Guide for detailed CI configuration.

4. Review Results ​

Open the PixelCI web UI to review builds, compare screenshots, and approve changes. See the Usage Guide for a walkthrough.
