Mockly's Slack chat generator recreates the real client's flat message rows: channel headers, avatars, presence dots, grouped messages, always-on timestamps, light and dark themes, and PNG or video export.
Click to add messages, and add senders with names and avatars for a busy channel feel.
Set the channel name, adjust timestamps, and switch light or dark theme.
Hit Export for a PNG mockup or a chat video.
Messages render as flat, left-aligned rows with avatars and bold usernames, Slack's layout rather than chat bubbles.
Channel name with the # prefix, pin and headphone icons, and a "Message #channel" input that follows your channel name.
A green presence dot next to the sender's avatar, and always-visible 24-hour timestamps on the first message of each run.
Consecutive messages from the same person group under one name and avatar, like the real client.
Light and dark themes that mirror Slack's palette, plus device frame and PNG or video export.
