Zero-cost SEO & GEO search radar. Proofs your search presence the way a printer proofs a sheet — no dashboard, no $130/month, no hallucinated advice.

jev-seo is a free, MIT-licensed, open source alternative to Semrush and Ahrefs ($130+/month) that audits local files, validates schema, checks robots.txt, and scores AI citation likelihood. One Rust binary under 30MB RAM, hundreds of files audited in under a second, sixteen commands, zero subscriptions, zero paid data APIs.

Agent native

A stdio JSON-RPC 2.0 MCP server feeds the same 19 tools into Claude Code, Gemini CLI, and Antigravity. SEO as a capability, not a dashboard.

Sixteen commands, no dashboard

Every tool proofs something measurable. Terminal in, verdict out.

Reasons Jev: the oracle is a decision engine, not a chatbox

Conversational LLMs write you a confident paragraph you then have to verify. Jev answers machine-native questions with machine-native types.

Fan-outone state, many questions, one request. 10x fewer round trips, 12x cheaper

Jev hates being asked for arithmetic or word counts. The CLI does the math; Jev does the judgment. That split is the whole architecture.

JEV SEALDECISION ENGINE, NOT CHATBOX

Proof the sheet before it ships

The audit reads your content the way a proofreader reads a galley. These are real patterns it catches:

em-dash density

"The—admittedly—fragile—stack—" ✗ 3 per 500 words

over 2 per 500 words = editorial tic. Flagged.

AI vocabulary

"delve · leverage · testament · foster · seamless" ✗ 4 hits

17 known boilerplate crutches. Stripped automatically.

heading hierarchy

H1 → H3, no H2 ✗ skip-level

illegal jump in the outline. Caught.

orphan pages

/blog/seo-for-vercel has 0 inbound links ✗ orphan

the link graph finds it. You fix the path.

cannibalization

3 pages target "rust grep" ✗ collision

keyword stems colliding. One winner per stem.

schema deprecation

"HowTo" schema present ✗ deprecated

no rich result. Migrate to the current type.

Direct answers, no hedge

The same plain declarative copy AI search engines quote. Short question, shorter answer.

Is jev-seo free?

Yes. jev-seo is MIT-licensed open source and costs zero subscriptions. It scrapes free DuckDuckGo endpoints and audits local files, so there is no paid API key required.

What does GEO mean in jev-seo?

GEO stands for Generative Engine Optimization: making content likely to be cited by AI search engines such as Gemini Overviews, Perplexity, and SearchGPT. jev-seo scores citation likelihood from 1 to 10 with TypeSafe Jev.

Does jev-seo need a credit card or paid API?

No. The only optional key is a free TypeSafe API key for semantic scoring. Ranking history, audits, schema validation, and SERP inspection all run locally with zero cost.

jev-seo vs Semrush or Ahrefs?

Semrush and Ahrefs are hosted dashboards that cost over $130 a month. jev-seo is a native Rust CLI and MCP server that audits local files, validates schema, checks robots.txt, and scores GEO citations — one binary, under 30MB RAM.

How do I install jev-seo?

cargo install jev-seo, or download the release binary for Windows, macOS, or Linux from GitHub Releases.

Does jev-seo collect my data?

No analytics, no telemetry. Audits read local files, rank history stays in one local SQLite database, and only semantic scoring calls reach the TypeSafe API with content you explicitly pass.
