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
Connect to WhatsApp, Telegram, Slack, Discord, Microsoft Teams, and more. Message NanoClaw from wherever you already communicate.
Memory & Context
Schedule recurring tasks with cron jobs. NanoClaw can publish your casts on a schedule without you having to ask each time.

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

Claude reads the Postiz skill so it knows what it can do, then autonomously discovers your Warpcast integration, composes your cast with optional channel targeting, and publishes it to Farcaster.

You can ask NanoClaw for anything Postiz supports on Warpcast: 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.
Cast into a channel
Say to NanoClaw
> @Andy cast "Shipped scheduling for agents today" into the /dev channel on Warpcast at 11am
NanoClaw: Sets the channel ID under the subreddit array and schedules for 11:00 AM.Cast with image
Say to NanoClaw
> @Andy post the launch graphic as a cast on Warpcast tomorrow morning with a one-line caption
NanoClaw: Uploads the image through Postiz and schedules the cast to your feed.Mirror from X
Say to NanoClaw
> @Andy every time I schedule a launch tweet, also cast the same text to Warpcast
NanoClaw: Schedules a matching Warpcast cast alongside the X post in Postiz.What should I know before posting to Warpcast from NanoClaw?
Warpcast 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.
- ✓Channel targeting uses the subreddit array for historical reasons: [{value: {id}}] where id is the Farcaster channel ID. Leave it empty to cast to your main feed.
- ✓Casts are short-form. Keep them concise and put links at the end so the frame or link preview renders cleanly.
- ✓Media is uploaded through Postiz first. Send the image in chat or reference a file path in the NanoClaw container.
- ✓Warpcast is a Farcaster client. Your casts are published to the Farcaster network and visible in other clients too.
Frequently asked questions about NanoClaw and Warpcast
How do I post to Warpcast from NanoClaw?
Install the Postiz skill in NanoClaw with npx skills add gitroomhq/postiz-agent, run postiz auth:login, and connect Warpcast in Postiz. Then message NanoClaw with the cast text, an optional channel, and a time. It creates the cast through Postiz and confirms when it is scheduled.
Can NanoClaw cast into a specific Farcaster channel?
Yes. Name the channel, such as /dev or /design, and NanoClaw places its ID in the channel targeting array so the cast lands in that channel rather than only your feed. If you skip the channel, the cast goes to your main feed. You can target a different channel per cast.
Is Warpcast the same as Farcaster?
Farcaster is the decentralized social protocol; Warpcast is the most popular client for it. Postiz connects through Warpcast, and casts you publish appear on the Farcaster network in any client. When NanoClaw says it posted to Warpcast, the cast is on Farcaster.
Can NanoClaw mirror my X posts to Warpcast?
Yes. Ask NanoClaw to include Warpcast whenever it schedules a post to X, or set up a recurring job that casts from the same content source. Each Postiz request can hold an X entry and a Warpcast entry with their own settings, so both publish at the same time.
Does NanoClaw need my Farcaster signer or recovery phrase?
No. Warpcast is connected to Postiz once through its authorization flow in the Postiz dashboard, and Postiz holds that connection. NanoClaw authenticates to Postiz with postiz auth:login or a POSTIZ_API_KEY. Never share a recovery phrase with any agent or chat app.
Post to other platforms from NanoClaw
The same Postiz skill covers 30+ channels. Start from the NanoClaw social media automation guide or jump to a platform that pairs well with Warpcast.
