Post to Reddit from OpenClaw

OpenClaw can submit text, link, image, and video posts to subreddits through the Postiz skill. You message OpenClaw with the subreddit and post idea, and it calls the Postiz CLI to check whether a flair is required, fetch the live flair list, and schedule the submission.

✓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

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 Reddit content through Postiz, so nothing waits on a manual trigger.

openclaw automations (cron)

openclaw automations create "0 9 * * 1-5" \
  "Check ~/content/reddit for a new post, look up the required flair for the target subreddit with postiz integrations:trigger, and schedule it for 9am." \
  --name "Reddit daily post" \
  --session isolated \
  --announce --channel telegram \
  --to "<your chat id>"

# openclaw cron is an alias for the same command

✓Cron jobs for hands-free daily posting schedules
✓Structured JSON output lets OpenClaw verify each step succeeded
✓Flair discovery and application handled automatically per subreddit

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 Reddit from Claude Code.

Claude Code

by Anthropic

Claude reads the Postiz skill so it knows what it can do, then autonomously discovers your Reddit integration, checks flair requirements, and schedules posts to the right subreddits.

Claude Code

> Post to r/programming and r/webdev
  about our new feature, schedule for
  tomorrow morning

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

Reddit + Other Platforms

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

Example

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

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

What can you ask OpenClaw to do on Reddit?

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

Link post with flair

Send to OpenClaw

> Post our changelog to r/selfhosted as a link post with the Release flair, scheduled for Monday at 9am.

Check flairs first

Send to OpenClaw

> Which flairs does r/programming require? Then post this write-up there as a text post with the right flair.

Multi-subreddit

Send to OpenClaw

> Post this tutorial to r/webdev and r/javascript at 10am, using the Tutorial flair on each.

Reddit rules OpenClaw has to follow

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

✓Every target subreddit needs a title, a type (self, link, image, or video), and an is_flair_required flag. OpenClaw fills these from your message, so include the subreddit and post type.
✓Some subreddits require a flair. OpenClaw fetches the live flair list through Postiz before posting, but it needs the flair template ID, not just a name.
✓Reddit titles are capped at 300 characters. Ask OpenClaw for a short, descriptive title and keep the detail in the body.
✓Cross-posting the same text to many subreddits quickly can trigger spam filters. Space out submissions or tailor the body per subreddit.

OpenClaw and Reddit: frequently asked questions

How do I post to Reddit from OpenClaw?

Install the Postiz skill in OpenClaw, run postiz auth:login, and connect your Reddit account in Postiz. Then message OpenClaw with the subreddit, post type, title, and time. It checks flair requirements, runs postiz posts:create, and confirms the scheduled submission. Ask for a draft to review first.

Can OpenClaw pick the right flair on Reddit?

Yes. Reddit flairs are exposed as a platform trigger in Postiz. OpenClaw runs postiz integrations:trigger to fetch the subreddit's live flair list, matches the one you named, and passes its ID in the flair setting. If the subreddit requires a flair, OpenClaw will ask you to choose one.

Can OpenClaw post to several subreddits at once?

Yes. The subreddit setting is an array, so one Postiz post can target multiple communities with their own title, type, and flair. Ask OpenClaw to post to two or three subreddits and it builds one entry per community. Space them out when a subreddit is strict about repeats.

Does OpenClaw need Reddit API credentials?

No. Postiz owns the Reddit OAuth connection, and OpenClaw only runs the Postiz CLI. You authenticate OpenClaw with postiz auth:login or a Postiz API key. There is no Reddit app registration, client ID, or rate-limit handling for you to manage.

Can OpenClaw post to Reddit on a schedule?

Yes. Create an OpenClaw automation with a cron expression and a prompt that reads your queue, resolves the flair through Postiz, and schedules the submission. Keep a human in the loop by asking OpenClaw to create drafts you approve in the Postiz calendar.
