Semaphore lets you test and deploy code at the push of a button with hosted continuous integration and delivery.

After you push code to GitHub, it quickly runs your tests on a platform with first-class Docker support and 100+ tools preinstalled. Semaphore lets you parallelize your builds, get feedback right inside pull requests, and deploy more often in a unified workflow. Already trusted by thousands of businesses around the globe, it can help your team move faster too.

Lucidchart empowers you and your team to create and collaborate on architecture diagrams, mockups, user flows, flowcharts, and other visuals in real time.

With Lucidchart, you can include these visuals in GitHub so team members can quickly understand an issue or pull request. Simply insert a public link to the Lucidchart document—the link will unfurl to show a preview, and unlike static diagrams, the link ensures that users always have access to the current version of the visual.
