A nine-year marketing veteran has open-sourced the Claude Code agent setup they use to manage 35 client accounts solo, covering ad management, SEO, website builds, and content workflows.
The repo, called Agents4Marketing, is built entirely on top of a Claude Code subscription. Rather than stitching together a dozen SaaS tools, the approach uses Claude's coding agent as the central hub, with prompt configurations and agent definitions for specific marketing tasks. The idea is straightforward: instead of hiring specialists for each channel, you configure AI agents that handle the repeatable parts of campaign management, keyword research, and site optimization.
It is still early. The project just launched and has minimal community traction so far. There is no documentation on reliability across different industries, and running 35 accounts through a single Claude Code subscription raises questions about rate limits and cost at that volume. But the concept is sound, and the repo gives a concrete look at how one practitioner structures agent-based marketing work in practice. For freelancers and small agency owners already paying for Claude, it is worth poking through the repo to see how the agent configurations are organized. At minimum, it is a useful reference for anyone building their own Claude Code workflows for client work.
