How It Works

Find Your Lemmy Integration

List your connected accounts and grab your Lemmy integration ID. You can also fetch available settings to see what options are supported.

Discovery

# List all integrations
postiz integrations:list

# Filter for Lemmy
postiz integrations:list | jq \
  '.[] | select(.identifier=="lemmy")'

# Get Lemmy settings schema
postiz integrations:settings <lemmy-id>

Choose Your Communities

Identify the Lemmy communities you want to post to. Each community requires a name, ID, and a post title. You can optionally include a URL for link posts.

Configuration

# Example community configuration
# subreddit = community name
# id = community ID from your instance
# title = post title (required, min 2 chars)
# url = optional link URL

echo '{
  "subreddit": [
    {
      "value": {
        "subreddit": "technology",
        "id": "comm-123",
        "title": "Great article on AI",
        "url": "https://example.com/article"
      }
    }
  ]
}'

Create Your Post

Schedule a Lemmy post with your content, target communities, and optional link URL. Posts can target one or multiple communities at once.

Also Works with Claude Code

Postiz Agent works as a CLI tool with any AI agent that can execute shell commands — including Anthropic's Claude Code.

Claude Code

by Anthropic

Claude reads the SKILL.md file to learn all available Postiz commands, then autonomously discovers your Lemmy integration, composes your post with the right community settings, and schedules it.

Claude Code

> Post an article about our new release
  to the technology and opensource
  communities on Lemmy

Claude will automatically run:
  postiz integrations:list
  postiz posts:create \
    -c "We just launched v2.0!" \
    -s "2025-03-02T09:00:00Z" \
    --settings '{"subreddit":[
      {"value":{"subreddit":"technology",
        "id":"comm-123",
        "title":"New Release v2.0",
        "url":"https://blog.example.com"}},
      {"value":{"subreddit":"opensource",
        "id":"comm-456",
        "title":"Open Source Release v2.0",
        "url":"https://blog.example.com"}}
    ]}' \
    -i "lemmy-id"

Lemmy + Other Platforms

Schedule the same content to Lemmy and other platforms in a single command. Each platform gets its own settings.

Terminal

# Post to Lemmy and Reddit simultaneously
postiz posts:create \
  -c "Check out our new open-source project! #opensource" \
  -s "2025-03-01T09:00:00Z" \
  --settings '{
    "subreddit": [
      {
        "value": {
          "subreddit": "technology",
          "id": "comm-123",
          "title": "New open-source social media tool"
        }
      }
    ]
  }' \
  -i "lemmy-id,reddit-id"

# Batch schedule a week of Lemmy content
for day in 1 2 3 4 5; do
  postiz posts:create \
    -c "Day $day community highlight! #fediverse" \
    -s "2025-03-0${day}T10:00:00Z" \
