Publish to Dev.to from OpenClaw

OpenClaw can publish and schedule Dev.to articles through the Postiz skill. You send OpenClaw the article or its source link, and it calls the Postiz CLI to set the title, upload a cover image, add up to four tags, pick an organization, and attach a canonical URL back to your original post.

⏰

Proactive Automation

Schedule recurring tasks with cron jobs. OpenClaw can publish your Dev.to articles on a schedule without you having to ask each time.

How Postiz Becomes an OpenClaw Skill

When you install Postiz Agent globally, OpenClaw automatically discovers it by reading the bundled SKILL.md file. This file tells OpenClaw what commands are available, what environment variables are needed, and how to compose Dev.to articles with the right settings.

✓Install from ClawHub with one command: openclaw skills install @nevo-david/postiz
✓OpenClaw reads the SKILL.md and learns all Postiz commands
✓Run openclaw skills check to confirm the postiz binary and credentials are in place
✓Skills are loaded on-demand, keeping the agent context clean
✓Works with any LLM backend: Claude, GPT, Gemini, Llama, and more

Install from ClawHub

# Install the Postiz skill from ClawHub
openclaw skills install @nevo-david/postiz

# Or with the skills CLI
npx skills add gitroomhq/postiz-agent

# Sign in with OAuth2 (or set POSTIZ_API_KEY)
postiz auth:login

# Verify OpenClaw sees it

Dev.to Publishing with OpenClaw

Message OpenClaw from any platform — it reads the Postiz skill, discovers your Dev.to integration, and handles the entire publishing workflow autonomously.

🦀

From Any Chat App

WhatsApp, Telegram, Slack, Discord...

Send a message to OpenClaw from your favorite chat app. It runs as a persistent daemon on your machine, so it picks up your message, discovers your Dev.to account via Postiz, formats the article, and publishes it — all while you go about your day.

WhatsApp / Telegram

You: Publish my TypeScript tips article
  to Dev.to under our org, use the
  cover image from ~/images/ts-tips.png

OpenClaw: Got it! Here's what I'll do:
  1. Upload ts-tips.png as cover image
  2. Read your draft from ~/drafts/ts.md
  3. Publish under your organization

  Done! Your Dev.to article is live.
  Post ID: abc-123

Scheduled & Proactive

openclaw automations for recurring content

OpenClaw automations run on cron expressions in an isolated session and can announce results to a chat channel. Create one that drafts and schedules your Dev.to content through Postiz, so nothing waits on a manual trigger.

openclaw automations (cron)

openclaw automations create "0 9 * * 1-5" \
  "Check ~/content/devto for a new Markdown article, publish it to Dev.to with cover.png, a canonical URL to the original, and up to four tags, scheduled for 10am." \
  --name "Dev.to daily post" \
  --session isolated \
  --announce --channel telegram \
  --to "<your chat id>"

# openclaw cron is an alias for the same command

Why OpenClaw + Postiz for Dev.to

OpenClaw's skill system makes Postiz a natural fit. The agent reads the SKILL.md to understand every available command, then autonomously chains them together for Dev.to workflows.

✓Message from WhatsApp to publish a Dev.to article — no terminal needed
✓Cron jobs for hands-free weekly publishing schedules
✓Structured JSON output lets OpenClaw verify each step succeeded
✓Cover images uploaded and attached automatically
✓Cross-post to Dev.to + other platforms in a single conversation
✓Model-agnostic — works with Claude, GPT, Gemini, or open-source LLMs

Also Works with Claude Code

Postiz works with any AI agent that can run commands or call MCP tools — you ask, the agent does the work. That includes Anthropic's Claude Code, which has its own guide for posting to Dev.to from Claude Code.

Claude Code

by Anthropic

Claude reads the Postiz skill so it knows what it can do, then autonomously discovers your Dev.to integration, uploads your cover image, applies tags and organization settings, and publishes the article.

Claude Code

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

Claude: Done! Scheduled on Dev.to for
  tomorrow at 9:00 AM.

Dev.to + Other Platforms

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

Example

> Post "Excited to announce our new feature!" to
  Dev.to and LinkedIn tomorrow at 9am, then schedule
  a daily tip on Dev.to every weekday at 10am

OpenClaw: Done! Scheduled:
  - Dev.to + LinkedIn: tomorrow 9:00 AM
  - Daily tips on Dev.to: Mon-Fri 10:00 AM

What can you ask OpenClaw to do on Dev.to?

These are real messages you can send OpenClaw from WhatsApp, Telegram, Slack, or Discord. OpenClaw maps each one to the right Postiz command and Dev.to settings.

Org post with cover

Send to OpenClaw

> Publish this tutorial to Dev.to under the Postiz organization tomorrow at 10am, use cover.png, tags: javascript, cli, opensource, ai.

Canonical cross-post

Send to OpenClaw

> Cross-post my engineering blog article to Dev.to with the canonical link set to the original.

Series

Send to OpenClaw

Dev.to rules OpenClaw has to follow

Postiz enforces these Dev.to constraints when OpenClaw creates a post. Knowing them up front avoids a failed request.

✓The title is required. Postiz accepts up to four tags, and Dev.to tags must be lowercase single words.
✓Cover images are passed as an uploaded file with an id and path. Send the image with your request so OpenClaw can upload it first.
✓Set canonical whenever you republish from your own blog to avoid duplicate-content issues.
✓Posting under an organization needs the organization ID. Ask OpenClaw to list your Dev.to organizations before publishing.

OpenClaw and Dev.to: frequently asked questions

How do I publish to Dev.to from OpenClaw?

Install the Postiz skill in OpenClaw, run postiz auth:login, and connect your Dev.to account in Postiz. Then send OpenClaw the article in Markdown with a title, tags, and time. OpenClaw runs postiz posts:create with the Dev.to settings and confirms the schedule.

Can OpenClaw add a cover image to a Dev.to article?

Yes. Send the image with your message. OpenClaw uploads it through postiz upload, then passes the file id and path in the main_image setting. Dev.to displays it as the article cover in feeds and at the top of the post.

Can OpenClaw publish under my Dev.to organization?

Yes. Postiz exposes your Dev.to organizations, and OpenClaw passes the organization ID in the organization setting. Ask "which Dev.to organizations can I post under?" and OpenClaw lists them before publishing to the one you name. Without an organization, the article posts under your personal profile.

Does OpenClaw need a Dev.to API key?

No. Postiz holds the Dev.to connection, and OpenClaw only runs the Postiz CLI. You authenticate OpenClaw with postiz auth:login or a Postiz API key, so no Dev.to API key is stored in OpenClaw's configuration. Revoke access from Postiz at any time and OpenClaw loses it as well.

Can OpenClaw cross-post my blog to Dev.to automatically?

Yes. Create an OpenClaw automation with a cron expression and a prompt that checks your content folder, publishes new articles to Dev.to with a canonical URL, and schedules them. Ask for drafts if you want a human to approve before publishing.
