ZensInk
Free SEO toolkit for indie builders. Four CLI tools for keyword research, volume analysis, ranking data, and competitor gaps — zero dependencies, Python 3.10+ stdlib only. A Pro engine automates the full pipeline from seed keywords to prioritized content plan.
Why
Ahrefs costs $108/month. SEMrush starts at $129.95. For a solo builder or a two-person team, that’s rent money. The best SEO tools should be free, fast, and scriptable — not locked behind a dashboard you barely use.
The Free Toolkit
Four MIT-licensed CLI tools. Zero dependencies. Clone and run.
Keyword Research

Self-Tested on Echoir
We ran the full audit pipeline on Echoir, our AI divination platform. The priority matrix surfaced 23 immediately actionable content targets — long-tail clusters like “yes or no tarot” with solid demand and thin competition. The audit output is included with the Pro package as a real-data case study.
