Finally, a GUI for certificate management. No more checking if CertBot actually ran. CertKit gives you one dashboard to see every cert, every renewal, every domain—before they expire and ruin your weekend. Built after the third production outage from a failed ACME challenge that nobody noticed.

Just point a DNS CName at us, and we’ll automatically discover, provisioning, validation, renewal, and deployment of certificates. Through an actual UI that can be easily monitored. Supports wildcards, multi-domain, whatever complexity you've accumulated over the years. No DNS API keys to leak. No cron jobs to debug. No Kubernetes required.

Built by the TrackJS team who are known for building simple and reliable tools that Just Work™️.

CertKit is free while in beta. Help us shape the future of SSL Certificate Management.

GitHub Skyline features and specs

  • Visual Representation
    GitHub Skyline offers a unique 3D visual representation of a user's contributions, making it easier to understand and analyze contribution patterns over time.
  • Engagement
    The 3D view and interactive design of Skyline can increase user engagement by providing a more immersive experience when viewing contribution activity.
  • Sharing and Presentation
    Skyline images can be shared on social media and other platforms, giving users a visually appealing way to showcase their GitHub activity and accomplishments.
  • Motivation
    Seeing contributions in a 3D landscape format can motivate users to maintain or increase their activity to improve their skyline visualization.

Possible disadvantages of GitHub Skyline

  • Limited Usefulness
    The 3D representation may not be as useful for serious analysis as traditional contribution graphs, which provide more detailed and comprehensive insights.
  • Computational Requirements
    The 3D rendering of contributions can be computationally intensive, potentially causing performance issues on less powerful devices.
  • Accessibility
    The reliance on 3D visualization can create accessibility challenges for users with visual impairments or those who use screen readers.
  • Novelty Factor
    As a relatively novel feature, some users might view GitHub Skyline as more of a gimmick than a tool of substantial value.

  • SSL Certificate Lifecycle
    Request, renew, and remove certificates without code changes or command line
  • SSL Certificate Monitoring
