seomachine is an open-source Claude Code workspace — structured around a CLAUDE.md configuration — purpose-built for writing long-form, SEO-optimized blog content at scale. It ships with specialized sub-agents for keyword mapping, internal linking, meta generation, title testing, and content optimization, each operating in a defined lane and passing structured output to the next stage in the pipeline. The architecture is a practical demonstration of Claude Code's multi-agent capabilities applied to a specific, high-value use case. The included real-world example is configured for a podcast company, showing how to adapt the workspace to a particular domain's content strategy. Trending with 3.7k stars and growing, it's resonating with indie builders who want to own their AI content pipeline rather than pay SaaS subscription fees for tools built on the same underlying APIs. Beyond the immediate use case, seomachine is notable as an example of the emerging "CLAUDE.md-driven workflow" pattern — using Claude Code's instruction layer to encode not just tool access but multi-stage business processes. This pattern will proliferate rapidly, and seomachine is one of the cleaner public examples of how to structure it properly.

Reviewer scorecard
“The CLAUDE.md-driven sub-agent pattern for domain-specific workflows is exactly how I want to be building things. seomachine is well-structured and the real-world example makes it immediately forkable for other verticals — this is the template I've been looking for.”
“No API to speak of. It's a publishing platform, not a developer tool. Built-in audience is the value proposition.”
“AI-generated SEO content is already flooding search results and Google is actively devaluing it. A tool that makes it cheaper to produce more AI content isn't solving the right problem — the bottleneck is quality and originality, not production throughput.”
“10% revenue share is expensive at scale, but the built-in discovery and reader network provide real value.”
“seomachine is a harbinger of the CLAUDE.md-as-business-process era — where entire workflows are encoded in agent instructions rather than software. Every content-heavy business will have a version of this within 12 months, whether they build it themselves or buy a SaaS version.”
“For small content teams and solo creators who can't afford an SEO agency, seomachine provides a genuinely capable multi-stage pipeline. The internal linking agent alone is worth the setup time — that's always been the tedious part of scaling a content site.”
“The simplest way to start writing and getting paid. The network effect brings readers you wouldn't find elsewhere.”
