Also Works with OpenClaw

Postiz Agent works as a CLI tool with any AI agent that can execute shell commands — including OpenClaw, the open-source personal AI agent.

🦀

OpenClaw

Open-source AI agent

Claude reads the SKILL.md file to learn all available Postiz commands, then autonomously discovers your Dev.to integration, uploads your cover image, applies tags and organization settings, and publishes the article.

OpenClaw

> Publish my React tutorial to Dev.to
  under our org with a cover image,
  tag it with react and webdev

Claude will automatically run:
  postiz integrations:list
  postiz upload ./cover.png
  postiz posts:create \
    -c "$(cat react-tutorial.md)" \
    -s "2025-03-02T09:00:00Z" \
    --settings '{"title":
      "React Tutorial",
      "main_image":{"id":"...",
        "path":"uploaded-url"},
      "organization":"org-id",
      "tags":[...]}' \
    -i "devto-id"

Dev.to + Other Platforms

Publish the same article to Dev.to and other platforms in a single command. Each platform gets its own settings.
