Boost Messages

Thank boosters with a designed message and a banner generated from their avatar, plus an optional private DM, and a test button that sends the real thing.

When somebody boosts the server, Arclo posts a message with a banner drawn at that moment from their avatar and your artwork. Nothing is pre-rendered.

Setting it up

Switch it on
Community → Boost Messages.
Pick a channel
Arclo needs Send Messages, Embed Links and Attach Files there.
Choose a theme
18 ready-made banner designs across 6 categories. Picking one replaces the banner's whole layout (the message is untouched), so choose before you start customizing it.
Edit the banner
In the banner studio. Move the avatar, change the text, swap the artwork.
Or upload your own
Upload image replaces the generated banner with yours (PNG, JPG, WebP or GIF, up to 8 MB). It is sent as it is, so a GIF stays animated and it is never recolored. The Banner switch turns the image off entirely.
Write the message
The standard message editor, in Components V2 (the default) or a Traditional Embed.
Send yourself a test
Send test message posts the real message to the real channel within about ten seconds, with your account as the booster and a small Test boost message line above it. It sends what the editor shows, unsaved changes included, and with the DM switched on it sends that to you too. The system has to be switched on first.

The banner is drawn at send time, with that member's avatar.

The private DM

Booster DM is an optional thank-you sent to the booster directly. It is off by default and is a separate design from the channel message: always a classic embed with its own color (random color included), while the banner stays with the channel message. If their DMs are closed the channel message still posts, and the log records Boost DM failed.

Matching your embed color

Recolor to embed color sits beside the theme library and is on by default. It repaints every chromatic part of the banner, the vector layers and the pixels of the artwork, in your embed color's hue, while each part keeps its own saturation and lightness. A cyan embed really does mean a cyan banner, including its background. Grays are left alone, a near-gray embed color recolors nothing, and an uploaded image is never recolored. With a random embed color, each banner follows the color that message drew.

Placeholders

Placeholder	Becomes
`{user}`	Mentions the booster
`{username}`	The booster's username
`{display_name}`	The booster's display name
`{user_id}`	The booster's Discord id
`{server}`	The server name
`{boost_count}`	Total boosts on the server
`{boost_level}`	The server's boost level (0–3)
`{member_count}`	The server's member count
`{avatar}`	Booster avatar URL, for icon fields
`{server_icon}`	Server icon URL, for icon fields

Banner text takes the same placeholders apart from the mention and the image URLs. {user} written there prints the display name, because an image cannot ping anybody.

Detection

No Discord setting is required for a first boost

Arclo notices a boost from the member update itself (their boosting since date appearing), and Discord's own boost system message is a second path. The two never double-post: one member is thanked at most once in any ten minutes. A member who is already boosting and adds another boost changes nothing on their member, so that boost is only seen through Discord's system message. Keep Send a message when someone boosts this server on in Discord's System Messages settings if you want repeat boosts thanked too.

Logging

Four actions through the Boost logger: Boost thanked, Boost message failed, Boost DM sent and Boost DM failed. They are exactly what the send path decides, so no switch on the page is dead. Switch it on from this page or from Logging.

Still stuck? Ask in the support server: somebody there has almost certainly configured this before.
