Build an OpenClaw Reddit Bot: Monitor and Engage Automatically
Reddit is one of the richest sources of real-time information on the internet. Whether you are tracking mentions of your product, monitoring industry trends, or curating content for your team, manually checking subreddits is tedious. With OpenClaw, you can build a bot that monitors Reddit, filters relevant content, creates digests, and delivers them to you automatically.
This guide covers setting up the Reddit skill, configuring monitoring, and building useful automation workflows.
OpenClaw Reddit bot overview
What You Can Build
With OpenClaw and the Reddit skill, you can:
Monitor keywords across all of Reddit or specific subreddits
Track subreddits for new posts matching your interests
Create daily/weekly digests of relevant posts
Curate content by having the AI filter noise and summarize valuable posts
Get real-time alerts when specific topics appear
Research by asking your agent to find and summarize Reddit discussions
Important note: This guide uses the read-only Reddit skill. We are monitoring and reading public content, not posting comments or creating posts. Reddit's API terms restrict automated posting, and we respect that.

Reddit API setup steps
Keyword Monitoring
Basic Keyword Alerts
Monitor Reddit for mentions of specific terms:
openclaw cron add --name "reddit-keyword-monitor" "*/30 * * * *" \
"Search Reddit for new posts (last 30 minutes) mentioning these keywords:
- 'openclaw'
- 'ai agent framework'
- 'self-hosted ai assistant'
For each relevant result:
- Title and subreddit
- Post score and comment count
- Link to the post
- Brief summary (1-2 sentences)
Only notify me if there are results. Send via Telegram.
Ignore posts with score below 5 (likely spam)."
Brand Monitoring
Track mentions of your product or company:
openclaw cron add --name "brand-monitor" "0 * * * *" \
"Search Reddit for mentions of 'Inbounter' or 'inbounter.com' in the last hour.
Categorize each mention:
- Positive: Praise, recommendation, success story
- Neutral: Question, comparison, informational
- Negative: Complaint, bug report, criticism
For negative mentions, send an URGENT notification with the full post content.
For all others, include in the daily digest."
Competitor Monitoring
openclaw cron add --name "competitor-watch" "0 9,15,21 * * *" \
"Check Reddit for posts about these competitors: [competitor1], [competitor2].
Focus on:
- Feature announcements
- User complaints (opportunities for us)
- Pricing discussions

Summarize findings and send to my Telegram."
Subreddit Tracking
Daily Subreddit Digest
Get a curated summary of subreddits you care about:
openclaw cron add --name "reddit-daily-digest" "0 8 * * *" \
"Create a daily Reddit digest from these subreddits:
r/selfhosted — Top 5 posts from the last 24 hours
r/homelab — Top 5 posts
r/LocalLLaMA — Top 5 posts
r/artificial — Top 3 posts
r/MachineLearning — Top 3 posts
For each post:
- Title (linked to post)
- Score and comment count
- 2-3 sentence summary
- Why it might interest me (based on my interests in SOUL.md)
Skip memes, low-effort posts, and repeated topics from yesterday.
Send the digest to my Telegram and email it via Inbounter."
The email digest through Inbounter creates a nicely formatted newsletter-style email you can read at your own pace.
Niche Subreddit Deep Dive
For subreddits closely related to your work:
openclaw cron add --name "selfhosted-deep-dive" "0 18 * * *" \
"Review today's posts on r/selfhosted:

Content Curation
AI-Filtered Content Feed
The real power is using AI to filter signal from noise:

"Review the top 50 posts from the last 24 hours across:
r/programming, r/webdev, r/devops, r/golang, r/typescript
Apply these filters:
1. INCLUDE: Technical deep-dives, architectural insights, new tools worth knowing
2. INCLUDE: Posts with 100+ upvotes (community-validated quality)
3. EXCLUDE: Job postings, memes, rants without substance
4. EXCLUDE: Posts I have already seen (check past digests in Obsidian)
Rank the remaining posts by relevance to my interests.
Present the top 10 with summaries.
Send to Telegram and save to Obsidian Inbox/."

Research Workflows
Ask-Based Research
Use your agent to research topics on Reddit:
You: What does Reddit think about Tailscale vs WireGuard for personal VPN?
Agent: I searched Reddit for discussions comparing Tailscale and WireGuard.
Here's what I found from 15 relevant threads:
**Consensus:**
- WireGuard is preferred by users who want full control and understand networking
- Tailscale is preferred by users who want "it just works" simplicity
- No clear "winner" — it depends on use case
**For Tailscale:**
- Dead simple setup (r/selfhosted, 342 upvotes)
- MagicDNS is a killer feature (r/homelab, 198 upvotes)
- ACL management is better than manual WG configs (r/networking, 87 upvotes)
**For WireGuard:**
- No third-party dependency (r/privacy, 256 upvotes)
- Lower overhead and faster (r/wireguard, 178 upvotes)
- Free forever, no vendor lock-in (r/selfhosted, 145 upvotes)
**Notable quotes:**
- "Tailscale is WireGuard with a nice UI and identity management" (r/devops)
- "If you need mesh networking, Tailscale. If you need a tunnel, WireGuard." (r/homelab)

Historical Trend Analysis
You: How has Reddit sentiment about Docker changed over the past year?
Agent: I analyzed top posts mentioning Docker across r/devops, r/selfhosted,
and r/programming from the past 12 months...
Building the Digest Email
For email digests via Inbounter, format the content as clean HTML:
# Add to SOUL.md
### Reddit Digest Email Format
When sending Reddit digests via email:
Use this HTML structure:
- Clean, readable design
- Each post as a card with: title (linked), subreddit, score, summary
- Categorized by topic
- "Read on Reddit" link for each post
- Footer with: number of posts scanned, filter criteria used
Subject line format: "Reddit Digest - [date] - [count] posts"
Example email the agent generates:
Subject: Reddit Digest - Apr 5, 2026 - 12 posts
Today's curated Reddit posts:
🔧 DevOps & Infrastructure
1. "We moved from Kubernetes to Docker Compose and never looked back" (r/devops, 423↑)
A team shares their experience downscaling from K8s for a 10-person startup...

Configuration Tips
Rate Limiting
Reddit API has rate limits (60 requests per minute for script apps). Configure your checks accordingly:
# config.yaml
skills:
reddit-readonly:
rate_limit:
requests_per_minute: 30 # Stay well below the limit
cache_ttl: 300 # Cache results for 5 minutes
Deduplication
Avoid showing the same post in multiple digests:
# SOUL.md
### Reddit Deduplication
Maintain a list of Reddit post IDs you have already reported.
Store in /home/user/.openclaw/data/reddit-seen.txt
Check this list before including a post in any digest or alert.
Add new post IDs after reporting.
Keep only the last 30 days of entries.
Relevance Scoring
Help the agent understand what you find interesting:
# SOUL.md
### My Reddit Interests (for relevance scoring)
High interest:
- Self-hosted software and alternatives to SaaS
- AI/ML practical applications (not hype)
- System architecture and scalability
- Developer tools and productivity
Medium interest:
- Programming language news
- Cloud provider comparisons
- Open source project announcements
Low interest:
- Job market discussions
- "What laptop should I buy" posts
- Salary comparison threads
- Language war debates
Privacy and Ethics
Respect Reddit's Terms
Use read-only access — do not automate posting or voting
Respect rate limits
Include a descriptive user agent string

Do not index or archive deleted posts
Respect author requests to remove content
Privacy and rate limiting best practices
Frequently Asked Questions
Is this allowed by Reddit's API terms?
Yes, reading public posts via the official API with proper credentials and rate limiting is explicitly supported. Automated posting and voting are restricted.
How much does the Reddit API cost?
The free tier allows 60 requests per minute for personal/script use. This is more than sufficient for monitoring and digest creation. The paid tier is for commercial applications with high volume.
Can the agent post comments on Reddit?
Technically possible but we strongly recommend against it. Reddit's community values authentic engagement. Automated comments are generally detectable and poorly received.
How do I monitor multiple subreddits efficiently?
Use Reddit's multi-subreddit syntax: r/subreddit1+subreddit2+subreddit3. This counts as one API request instead of three.
Can I track specific Reddit users' posts?
Yes, the API supports fetching a user's public posts. Useful for tracking industry thought leaders or competitors' official accounts.
How accurate is the AI's content filtering?
With good SOUL.md instructions, expect 85-90% relevance in filtered digests. The agent learns from your feedback — if you tell it a post was not relevant, it adjusts future filtering.
