Most "best scheduler" lists stop at Instagram and LinkedIn. Founders who ship still need a **community Discord** announcement and a **team Slack** update on the same calendar as X and LinkedIn. The 2026 filter for that job is simple: native Discord publish and native Slack publish in one workspace, not Zapier duct tape and not a second bot.

## Short answer

For solo founders and small teams who announce in Discord **and** Slack alongside public networks, **DunSocial** is the direct fit. Discord and Slack are both generally available on the flat **USD 20/mo** or **USD 192/yr** plan (14-day trial; 1 seat included; extra seats **$8/mo**), with the same AI Memory, Voice Presets, hosted MCP (**53 tools**), [CLI](/cli), and human confirm-before-publish flow as every other network.

Connect one Discord server and one Slack team per workspace, pick the channel when you compose, and schedule beside X, LinkedIn, Instagram, Threads, Bluesky, Reddit, Pinterest, and YouTube Shorts (TikTok limited beta). Slack as a **publish destination** is a separate app from the Slack chat agent. Start at [app.dunsocial.com/login](https://app.dunsocial.com/login), or read [/platforms/discord](/platforms/discord) and [/platforms/slack](/platforms/slack).

| Tool | Discord publish? | Slack publish? | Entry price unit (14 Sep 2026) | MCP/CLI? | Best when |
| --- | --- | --- | --- | --- | --- |
| DunSocial | Yes (GA; one server/workspace) | Yes (GA; one Slack team/workspace; publish app ≠ chat agent) | USD 20/mo or USD 192/yr; seats $8/mo; 14-day trial | Yes. **53** MCP tools + CLI included | Founders who need Discord + Slack on one calendar with memory and human confirm |
| Buffer | No native channel (Zapier/IFTTT only) | No native channel (notifications/automations only) | Free (3 channels); Essentials from ~USD 5/channel/mo billed yearly | MCP yes; CLI via Buffer API ecosystem | Queue + composer strength on public networks; free start |
| Later | No (not in published network list) | No | Starter from Later pricing (Social Set model) | No first-party MCP found | Instagram-led visual planning |
| Typefully | No | No | From ~USD 12.50–19 per social set / mo (plan-dependent) | MCP yes | Text-first writing on X, LinkedIn, Bluesky, Threads |
| Postiz | Yes (documented Discord channel) | Yes (documented Slack channel) | Hosted Standard USD 29/mo (5 channels); self-host free | MCP + API on paid/hosted | Wide channel set or self-host preference |
| Publer | No native publish network | No native (Slack/Discord via Zapier notify patterns) | Professional from low per-account base | MCP beta / gated on higher access | Account-priced broad public networks |
| Hootsuite / Sprout | No native Discord publish | Slack as collaboration/notifications, not a publish destination | Suite pricing (often ~USD 99+/user/mo band) | Hootsuite Perch MCP for social publish | Inbox, listening, enterprise approval workflows |

## Why Discord + Slack in the same scheduler matters

A launch is rarely one post. You want the public thread on X or LinkedIn, the community note in Discord, and the internal heads-up in Slack to land from one draft and one calendar view. When those destinations live in separate tools, copy drifts, times slip, and someone still has to paste into Discord at ship time.

DunSocial treats Discord and Slack as first-class publish destinations on the same flat plan as the other generally available networks. You compose once, adapt per network, schedule the channels you need, and keep AI Memory and Voice Presets consistent across the campaign. For Discord-only readers, the companion post [best social media scheduler for Discord](/blog/best-social-media-scheduler-for-discord) still helps; this page is the combined Discord **and** Slack buying guide.

## DunSocial for Discord and Slack

### Discord

Authorize the DunSocial bot on **one Discord server** per workspace. Pick a text or announcement channel at compose time. Limits from the live platform page: **2,000 characters**, up to **10 attachments**, **25 MB** total request. Text and attachments only (no embed builder, forums, or polls in this version). Full detail: [/platforms/discord](/platforms/discord).

Discord is generally available, not a waitlist beta. Adding it does not change the USD 20 plan price. Over MCP, assistants can `list_discord_channels` then `schedule_discord_post` or `publish_discord_now` on the same connected server as the web app.

### Slack publish

Connect the dedicated **Slack publish** app and authorize **one Slack team** per workspace. Pick a public or private channel when you compose. Limits: **4,000 characters**, up to **10 files**, **50 MB per file**. Full detail: [/platforms/slack](/platforms/slack).

Important distinction: the Slack agent in Settings drafts and schedules to **other** networks from Slack chat. Slack as a **publish destination** is a separate Slack app you connect from Compose / Connect. Do not assume one install covers both jobs.

### Same plan as the rest of the calendar

Discord and Slack sit on the same USD 20/mo or USD 192/yr workspace as X, LinkedIn, Instagram, Threads, Bluesky, Reddit, Pinterest, and YouTube Shorts, with TikTok in limited beta. Included: AI Memory, Voice Presets, hosted MCP with **53 tools**, [CLI](/cli), REST API, and human confirm before AI-written work goes live. See [/pricing](/pricing) and [/mcp](/mcp). Founder and developer paths: [/for/founders](/for/founders), [/for/developers](/for/developers).

## How other tools compare

### Buffer

Buffer remains strong on composer UX, queue management, and a real free tier. Supported publish channels on Buffer's pricing page (retrieved 14 September 2026) include LinkedIn, Threads, Pinterest, Bluesky, YouTube, X, Google Business Profile, Instagram, Mastodon, TikTok, and Facebook. Discord and Slack are not listed as native Buffer channels; Zapier and IFTTT cover notifications and cross-app flows instead. Essentials starts around **USD 5 per channel per month** on yearly billing (volume discounts apply). Official Buffer MCP is available on every plan. Pick Buffer when public-network queue and free start matter more than native Discord + Slack publish.

### Later / Typefully / Postiz / Publer

**Later** wins on visual Instagram-led calendars. Its published scheduling networks emphasize Instagram, Facebook, TikTok, LinkedIn, Pinterest, YouTube, Threads, and related creator surfaces. Discord and Slack are not documented as native Later publish destinations on write day.

**Typefully** wins on writing UX for text platforms (X, LinkedIn, Bluesky, Threads, Mastodon). It ships first-party MCP. Discord and Slack are outside that text-first set.

**Postiz** documents both [Discord](https://postiz.com/channels/discord) and [Slack](https://postiz.com/channels/slack) as scheduleable channels, with hosted Standard from **USD 29/mo** (5 channels) and a self-host option. It is a fair alternative when you want a wide channel catalog or to run your own infra. Compare price unit and confirm-before-publish habits against DunSocial's flat USD 20 workspace with brand memory.

**Publer** documents a broad public-network set (Facebook, Instagram, X, LinkedIn, Pinterest, YouTube, TikTok, Telegram, Mastodon, Threads, Bluesky, and more). Discord and Slack are not in the Publer networks list as native publish targets; Zapier patterns often notify Slack/Discord after Publer publishes elsewhere. Pick Publer when account-priced public networks fit the budget.

### Hootsuite / Sprout Social

Pick a suite when **inbox**, listening, employee advocacy, or enterprise approvals are the primary job. Hootsuite and Sprout Social integrate Slack for collaboration and notifications; that is not the same as scheduling Slack channel announcements as a social destination. Native Discord publish is not the suite buying reason. Entry price units usually sit above the indie USD 20 band. Hootsuite's Perch MCP path is for social publishing inside the Hootsuite product stack, not a Discord+Slack calendar substitute for founders.

## Practical workflow: one launch, three surfaces

1. **Draft once** in DunSocial (or via MCP/CLI) with brand Memory loaded.
2. **Adapt copy** per network: short for X, longer for LinkedIn, channel tone for Discord and Slack.
3. **Connect** Discord (one server) and Slack publish (one team) if not already connected.
4. **Schedule** the Discord channel, Slack channel, and public networks on the same calendar.
5. **Confirm** before anything AI-assisted goes live, then watch the shared queue.

Optional MCP-style prompt: list Discord and Slack channels, draft a launch note in brand voice, schedule Discord + Slack + X for the same window, and wait for human confirm. Same calendar whether you worked in the browser, Cursor, Claude, or ChatGPT.

## FAQ

Yes. Hosted MCP with **53 tools** is included, along with the CLI and API. No separate developer tier.
