jev-seo

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.

FIG. 01 audit — batch on-page proof LIVE

Real output shape. The line about to change flashes amber before it lands; red is reserved for flagged defects.

FIG. 02 rank — drift trace

Ballistic needles: sweep, overshoot, settle. Green is good — red would mean the page fell.

FIG. 03 robots — AI crawler radar

Five generative indexers, one pass.

The stack that costs $130/month doesn't do this

Zero subscriptions

Scrapes DuckDuckGo HTML and suggest endpoints directly. No credit card, no paid API key, no DataForSEO top-up. The bill is ₹0 forever.

No hallucinated advice

TypeSafe Jev System One scores with typed Choice / Score / Noul primitives. Deterministic judgments, not chatbot essays. What it flags is real.

Fast and local

A native Rust binary under 30MB RAM. Audits hundreds of markdown and HTML files in under a second. Rank history lives in one local SQLite file.

Agent native

A stdio JSON-RPC 2.0 MCP server feeds the same 8 tools into Claude Code, Gemini CLI, and Antigravity. SEO as a capability, not a dashboard.

Ten 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.

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.

Set up in two lines

# 1 — install (crates.io)
$ cargo install jev-seo

# 2 — free oracle key for semantic scoring
$ export TYPESAFE_API_KEY=your_key_here

No credit card. No hosted dashboard. No telemetry. One binary, one local SQLite file, 30MB of RAM.
