Demo videos for dev tools

A developer-tool video can show a command, the work it triggers, and the output a developer needs to check. Legible code and accurate behavior matter more than decorative terminal effects.

These scenes use Relay, a fictional product from our example library. Click any one to play it with sound.

Keep code and output readable.

Install commands, configuration, and output should match a working example. We leave enough time to read the important lines and remove unrelated console output from the framing.

Open full-size image in a new tab. Terminal demonstration showing git push origin main, enumerating eleven objects, counting eleven of eleven, and delta compression using up to ten threads.
This frame from the git-push lesson keeps the command and its first output lines together. A viewer can connect the action to enumeration and counting before the lesson introduces the next stage.Film still · staged exampleView full size ↗Full source film ↗

One run can explain the tool.

An install followed by a handled request can establish the basic workflow. Include a second run if it explains an error, a cache hit, or a changed configuration.

Open full-size image in a new tab. Close terminal view of bun test retry. The transient-failure test passes, the maximum-attempts test fails, an expectation error is printed, and the summary reads one pass and one fail.
The retry test reports one pass and one failure, with the failing behavior named above the summary. This is the state a second run must visibly change when an error recovery belongs in the demonstration.Film still · staged exampleView full size ↗Full source film ↗
