Post the same message to multiple Discord servers at once: tools compared (2026)

Prompt template

List my Discord servers and their self-promotion, showcase or announcement channels, then post this message from my own account in the channels I pick: your message. Do a dry run in each channel first, then send it and give me the link of each message.

Overview

Indie developers, creators, event organizers and community managers often share one piece of news in many Discord servers: a launch, a new version, an event, a giveaway, a job post. They are members of these servers, not admins, and each server has its own place for it: #self-promo, #showcase, #events or a partners channel.

They want the post to go out in every server where it belongs, under their own name, with a link to each post so they can answer the replies. They do not want to open ten servers, find the right channel in each one and paste the same text ten times.

Why it's hard

  • Every cross-posting tool assumes that you manage the servers. Xenon's sync says you "need to be an administrator on both servers". CloudMod's Channel Mirror needs the Manage Webhooks permission. PostRite lists "Only servers where you have Administrator or Manage Server permission". SocialMate's bot needs Manage Server on each server, and SocialMate's own guide says that webhooks work for servers you own, not for servers where you are only a member. FoPost connects "every server you manage" through a webhook URL.
  • Discord's own Channel Following goes the other way. It only works from an announcement channel, and announcement channels are only available to Community servers. The server that receives the posts must follow you, and only a person with Manage Webhooks there can do it. The posts come from a bot named after your server, and Discord allows 10 publishes per hour.
  • By hand, it is one server at a time. For each server, you find the channel where self-promotion is allowed, paste the message, add the image again and send it. Then you keep the links somewhere to come back to the replies.
  • A selfbot puts your account at risk. Discord's Self-Bots article says that automating a normal user account outside the OAuth2 or bot API is forbidden and can result in account termination. Selfbot tools also ask for your user token, which works like your password.
  • Posting too much looks like spam. Discord's Community Guidelines say: "Do not send unsolicited bulk messages (or spam) to others." SocialMate's guide gives the same warning: posting too often in communities you do not own can get you flagged as spam.

How Reduck does it

Your AI agent runs Reduck's Discord scripts in your own Chrome, where you are already signed in to Discord. You add no bot, create no webhook and paste no token, and each message goes out under your own name.

  1. It finds the right channels. whoami confirms which Discord account the browser uses. list_servers lists your servers, and list_channels gives the name, category and link of each channel in one server. Your agent shows you the channels whose names fit, such as #self-promo or #showcase, and you pick.
  2. It checks before it sends. post_message has a dry run: it opens the channel, prepares the message and any file, and sends nothing. If a channel does not open for your account, the run stops with an error.
  3. It posts as you, one channel after the other. post_message posts the text, up to 2000 characters, with one file if you add one. It returns the message id and the time, so your agent gives you the link of each post. For a forum channel, create_forum_post creates a post with a title and an opening message.
  4. It adapts the text when you ask. Each post is its own call, so the agent can change the language, the tags or the length for one server.
  5. It fixes mistakes. edit_message replaces the text of your own message, and delete_message deletes a message.

What you get: your message in every server you picked, under your name, also in servers where you are only a member, with one link per post to follow the replies.

Post where you are welcome

The same message in many servers is useful news or spam, depending on where it goes. Before your agent posts:

  • Pick channels made for it. Self-promotion, showcase, events or partners channels, not general chat.
  • Read each server's rules. A server can allow self-promotion in one channel only, or only for its active members. The rules are often in a #rules channel or in the pinned messages.
  • Post once per server. One channel in each server, not every channel.
  • Keep the pace of a person. A few servers, not a mass post, and no unsolicited DMs.

How to start

  1. Create a free account at reduck.ai.
  2. Install the Reduck extension in Chrome and pair it.
  3. Connect Reduck to your agent: docs.reduck.ai.
  4. Ask: "List my Discord servers and their self-promotion, showcase or announcement channels, then post this message from my own account in the channels I pick: {your message}. Do a dry run in each channel first, then send it and give me the link of each message."

When you already have the channel links, the Reduck CLI posts in all of them, one after the other. Sign in once with login or set REDUCK_API_KEY, and stay signed in to Discord in that Chrome, in one tab only:

npx @reduck-ai/cli@latest run --sequential --script reduck/discord.com/post_message channelUrl=https://discord.com/channels/SERVER_A/CHANNEL_ID "message=Version 2.0 is out: https://example.com" --script reduck/discord.com/post_message channelUrl=https://discord.com/channels/SERVER_B/CHANNEL_ID "message=Version 2.0 is out: https://example.com" --script reduck/discord.com/post_message channelUrl=https://discord.com/channels/SERVER_C/CHANNEL_ID "message=Version 2.0 is out: https://example.com"

Tools to post the same message to multiple Discord servers, compared

As each tool's own page describes it, read on October 30, 2026. "Not documented" means we did not find it on their page.

Reduck You Yes, every channel where you can write Nothing beyond your membership One by one, with edit_message and delete_message There is a free tier
Discord Channel Following A bot named after the source server No, the other server must follow you Source: an announcement channel of a Community server. Other server: Manage Webhooks Edits update the copies. A delete leaves "[Original Message Deleted]" Free, 10 publishes per hour
Xenon sync The original author's name and avatar No Administrator on both servers Carried over to the copy Premium only: $5.99, $10.99 or $15.99 per month
CloudMod Channel Mirror A webhook No Manage Webhooks Carried over to the copies Free plan (main server plus 3 sub-servers). Link $3.99, Network $7.99 per month
FoPost A webhook No, "every server you manage" A webhook URL per channel Not documented "Starting is free", paid prices not on its Discord page
PostRite Its bot, or a webhook No, "Only servers where you have Administrator or Manage Server permission" The bot installed, or a webhook per channel Not documented No free plan, 14-day trial. Basic $4.99 per month for 250 posts, each destination counts as one post
SocialMate Its bot No, its guide says servers you own or manage Manage Server for its bot Not documented "Free forever" account, multi-server posting on all plans
Webhooks with Zapier or Make The webhook's name and avatar No Admin access to create each webhook Not documented Depends on the automation tool
Selfbot with your user token You Yes Nothing Yes Forbidden by Discord: risk of account termination

Where the others are stronger: a mirror such as Xenon or CloudMod copies every new message by itself, carries edits and deletes over, and runs when your computer is off. Channel Following is built into Discord and free for your own community. FoPost also schedules and repeats posts, and PostRite schedules them. Reduck is for a post that must come from you, in servers that you do not manage, from an agent that also finds the right channel and adapts the text for each server.

FAQ

Yes, and the right one depends on your role in each server. If you manage the servers, a bot or a webhook tool such as Xenon, CloudMod, FoPost, PostRite or SocialMate copies or sends the message to each of them. If you are only a member, these tools do not work, because each one needs admin rights, Manage Server or Manage Webhooks in every server. Reduck then posts the message from your own account, one channel after the other, in every channel where you can write.
Yes, with Reduck, in every channel where your account can already write. post_message acts in your own Chrome, like you would by hand, so it needs no bot, no webhook and no permission beyond your role as a member. If a channel does not open for your account, post_message stops with an error and posts nothing there.
Yes. Reduck adds no bot to any server and creates no webhook. Your agent posts from the Discord tab you are signed in to, so each message shows your name and avatar, with no bot tag. A bot or a webhook can only post in servers where someone who manages the server added it.
It can, if the posts are spam. Discord's Community Guidelines say: "Do not send unsolicited bulk messages (or spam) to others." Discord's Self-Bots article also says that automating a normal user account outside the OAuth2 or bot API is forbidden and can result in account termination. Reduck acts in your own browser, one message at a time, with no token and no change to the Discord client, but it is still automation of your account, and we cannot promise that Discord will never flag it. Post only where each server's rules allow it, once per server, at the pace of a person.
Channel Following works the other way. You publish in an announcement channel of your own Community server, and other servers choose to follow it. Each following server needs a person with the Manage Webhooks permission to add it, the posts come from a bot named after your server, and Discord allows 10 publishes per hour. You cannot use it to post in a server that does not follow you.
Yes. Reduck posts as you, with your username and avatar. Xenon's sync keeps the original author's name and avatar on the copy, CloudMod and FoPost post through webhooks, and Channel Following posts come from a bot named after the source server.
Yes. Each post is its own post_message call, so your agent can adapt the message to each server: another language, the server's own tags, a shorter version for a busy channel. A mirror bot copies the same message everywhere.
Yes, one file per message, with the text as its caption. A message has at most 2000 characters. post_message refuses empty messages and forum channels: for a forum, create_forum_post creates a post with a title of up to 100 characters and an opening message.
Yes, one by one, from the links your agent gives you. edit_message replaces the text of your own message, and Discord shows an "(edited)" tag. delete_message deletes a message from its channel link and message id. A mirror bot such as Xenon or CloudMod carries edits and deletes over to the copies by itself.
Yes, when something runs the send on that schedule. Reduck has no scheduler of its own. In Claude Code, /loop followed by an interval and the prompt runs it again while Claude Code stays open, or a cron job can call the Reduck CLI at a fixed day and time.
Reduck posts in each channel of your list, one after the other, because Discord allows one active tab per account. Each channel is one run. The real limit is each server's rules: a few servers where your post is welcome is better than many where it is not.
No. The scripts run in your own Chrome, so your computer, Chrome and Discord must be open while the posts go out. Keep Discord open in one tab only. A hosted bot or a webhook tool sends from its own servers, also when your computer is off.
Yes. Reduck connects to Claude, ChatGPT, Cursor and any other MCP client, and it has a CLI and a REST API. Posting, editing and deleting are marked as writes, so a client that asks before a write asks you first.
