What is NanoClaw?

NanoClaw is an open-source AI assistant that runs each agent in its own Docker container and is built on Anthropic's Claude Agent SDK. It was created as a smaller, easier-to-audit alternative to OpenClaw. It connects to WhatsApp, Telegram, Slack, Discord, Microsoft Teams, iMessage, and more, and supports per-group memory and recurring jobs.

📦

Container-Based

NanoClaw runs in containers for easy deployment and isolation. Spin up your social media automation agent in seconds with Docker.

💬

Multi-Platform Chat

🧠

Memory & Context

NanoClaw remembers your preferences and past interactions. It learns your posting style and content strategy over time.

How Postiz Works with NanoClaw

NanoClaw discovers Postiz through its skill system. Add the Postiz skill to your NanoClaw fork and the agent reads the SKILL.md to learn every postiz command, then runs them inside its own container when you ask.

✓Install Postiz skill with npx skills add gitroomhq/postiz-agent
✓NanoClaw reads the SKILL.md and learns all Postiz commands
✓Authenticate with postiz auth:login (OAuth device flow) or a POSTIZ_API_KEY
✓Skills are loaded on-demand, keeping the agent context clean
✓Built on Anthropic's Claude Agent SDK, running in an isolated Docker container

Install Postiz

# In your NanoClaw fork: add the Postiz skill
npx skills add gitroomhq/postiz-agent

# Sign in to Postiz (OAuth device flow)

Reddit Posting with NanoClaw

Message NanoClaw from WhatsApp, Telegram, or Slack — it discovers your integrations via Postiz, composes your content, and handles the entire posting workflow from within its container.

🐳

From Any Chat App

WhatsApp, Telegram, Slack, or Discord

Send a message to NanoClaw from your favorite chat app. It runs as a background service in an isolated container, so it picks up your message, discovers your Reddit account via Postiz, finds the right flairs, and schedules the post — all while you go about your day.

NanoClaw

You: Post to Reddit about our new
  feature launch, schedule for tomorrow

NanoClaw: Got it. I'll run this every
  weekday at 9:00 AM and schedule the
  posts through Postiz.

Does Postiz work with other agents too?

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.

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.

Can NanoClaw post to Reddit and other platforms at once?

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

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

What can I ask NanoClaw to post on Reddit?

You can ask NanoClaw for anything Postiz supports on Reddit: a single post, a scheduled batch, or a recurring job. These are prompts you would type in WhatsApp, Telegram, Slack, or Discord. @Andy is NanoClaw's default trigger word; use whatever name you gave your agent.

Text post with flair

Say to NanoClaw

> @Andy post our tutorial to r/programming as a text post titled "How we cut CI time in half" with the Tutorial flair, tomorrow at 9am

NanoClaw: Fetches flairs via integrations:settings, sets type self, applies the Tutorial flair.

Link post to several subreddits

Say to NanoClaw

> @Andy share https://postiz.com/blog/... as a link post to r/SaaS and r/artificial at 11am with fitting titles for each

NanoClaw: Builds two subreddit entries with type link and separate titles in one Postiz post.

Check flairs first

Say to NanoClaw

> @Andy what flairs does r/SaaS require before I post there?

NanoClaw: Runs postiz integrations:settings and lists the flair options and whether one is required.

What should I know before posting to Reddit from NanoClaw?

Reddit has a few rules that Postiz enforces at publish time. NanoClaw applies them when you mention them in plain language, and asks when a required value is missing.

✓Every subreddit entry needs a title and a type: self (text), link, image, or video. Link posts also need url. NanoClaw asks for whatever is missing.
✓If a subreddit requires flair, is_flair_required is true and the flair object (id and name) must be set. NanoClaw can look up valid flairs with postiz integrations:settings before posting.
✓Give subreddit names without the r/ prefix in settings. In chat you can say r/programming and NanoClaw strips it.
✓Reddit titles are capped at 300 characters, and many subreddits have their own rules on self-promotion. Keep a human reviewing what NanoClaw queues.

Frequently asked questions about NanoClaw and Reddit

How do I post to Reddit from NanoClaw?

Install the Postiz skill in your NanoClaw fork with npx skills add gitroomhq/postiz-agent, run postiz auth:login, and connect your Reddit account in Postiz. Then tell NanoClaw the subreddit, title, post type, and time. It checks the subreddit's flair options and schedules the post through Postiz.

Can NanoClaw apply the right Reddit flair automatically?

Yes. Before posting, NanoClaw can run postiz integrations:settings for your Reddit channel to fetch live flair templates for the target subreddit. If flair is required, it sets is_flair_required to true and fills in the flair id and name you asked for, or lists the options so you can choose.

Can NanoClaw post the same content to multiple subreddits?

Yes. A single Postiz Reddit post takes an array of subreddit targets, each with its own title, type, and flair. Ask NanoClaw to post to two or three communities and it builds one entry per subreddit. Be mindful of each community's rules on cross-posting and self-promotion.

Which Reddit post types can NanoClaw create?

Four types: self (text body), link (needs a url), image, and video. Say "as a text post", "as a link", or attach media, and NanoClaw sets type accordingly. Image and video posts upload the file through Postiz first. Text posts support Reddit markdown in the body.

Can NanoClaw run a recurring Reddit posting job?

Yes. Ask in chat, for example "every Monday at 10am post the weekly digest from ~/content/reddit to r/ourcommunity". NanoClaw runs on that schedule and creates the post through Postiz. Because subreddits enforce rate and content rules, keep the job to communities you moderate or have permission to post in.
