ZensInk

SEO Toolkit for Indie Builders

CLI tools for keyword research, competitor analysis, and technical audits. Zero dependencies, pure Python.

English · 中文

Twenty CLI tools that cover the full SEO workflow — from discovering what people search, to clustering keywords by topic, to classifying search intent, to auditing your own site. No paid APIs. No Ahrefs. No subscriptions. Just free data sources wired together with Python.

Why

Ahrefs costs $200/month. SEMrush costs $130/month. For indie builders who just need to find keywords worth writing about, that's overkill.

zens.ink wires together free public data sources — Google Autocomplete, Bing Webmaster Tools, Google Search Console, Brave Search, Ahrefs Domain Rating — with zero Python dependencies.

Install

Option A — pip (recommended)

pip install zens-ink

After install, the zens-ink command is available globally:

zens-ink --help

Option B — git clone

git clone https://github.com/ZensInk/zens-ink-seo-package.git
cd zens-ink-seo-package

Quick Start

# Discover keywords (with a-z long-tail expansion)
zens-ink keyword_research "tarot" --expand

# Check real search volume
zens-ink keyword_volume "tarot reading" --country us

# Keyword difficulty (SERP-based, with Chinese mode)
zens-ink kd "塔罗牌" --zh

# Compare 3 competitors at once
zens-ink competitor_gap \
  --url https://yoursite.com/sitemap.xml \
  --compare https://competitor-a.com/sitemap.xml https://competitor-b.com/sitemap.xml

# Audit your build for SEO issues
zens-ink site_audit --dist dist --sitemap dist/sitemap.xml

# Check your own Google search performance
zens-ink search_performance

python3 -m zens_ink.keyword_research "tarot" --expand
python3 -m zens_ink.kd "tarot reading"
python3 -m zens_ink.site_audit --dist dist --sitemap dist/sitemap.xml

Use as Agent Skill

ZensInk works as an AI agent skill — let your AI assistant run SEO tools for you in plain language.

# Install for ClawHub / OpenClaw / Hermes compatible agents
npx skills add ZensInk/zens-ink-seo-package --skill zens-ink

Then just tell your AI: "find keywords for my tarot site" and it runs the tools for you. See SKILL.md for details.

Use as MCP Server (DSH / Claude / Codex)

ZensInk ships a built-in MCP stdio server — every tool becomes a native model tool (mcp__zensink__keyword_research, mcp__zensink__kd, ...). Pure stdlib, zero extra dependencies.

python3 -m zens_ink.mcp    # MCP stdio server on stdin/stdout

Add to DeepSeek Harness (DSH) — ~/.dsh/profiles/web/cordis.patch.yml:

- insert:
    - id: mcp-zensink
      name: '@deepseek-ai/dsh-mcp-client'
      config:
        serverName: zensink
        transport: stdio
        command: python3
        args: ['-m', 'zens_ink.mcp']
        toolCallTimeoutMs: 300000

For other MCP clients (Claude Desktop, Codex, ...), point the stdio command at python3 -m zens_ink.mcp. API keys are read from the package root .env as usual.

If the Pro package (zens_ink_pro) is installed alongside, its tools (winability, content_radar, competitor_radar, geo_score, geo_visibility, gap_deep, full_audit) are picked up automatically — the same server exposes everything available on that machine. OSS-only installs stay OSS-only.

Typical Workflow

keyword_research  →  find what people actually search
        ↓
keyword_volume    →  filter by real demand
        ↓
kd                →  pick keywords you can actually rank for
        ↓
competitor_gap    →  see what competitors already cover
        ↓
site_audit        →  make sure your pages are crawlable

Requirements

• Python 3.10+
• Zero dependencies — pure standard library
• Optional API keys (Bing, Serper, Brave, GSC) in .env — see .env.example
