Crawls auto-save continuously to ~/.bluesnake — there is no Save button, and closing the app never loses a crawl.

The desktop app — the human view of the same engine your scripts and agents drive.

One engine

Run it however you work.

People, terminals, and AI agents all reach for the same crawler — and read back the exact same results.

01

In the desktop app

A calm window for browsing crawls, resuming runs, and comparing them side by side. Click, don't type.

for people who like a GUI
02

From one command

A single, portable program — no runtime, no install ceremony. Schedule it, repeat it, fold it into your workflow.

$ bluesnake crawl …
03

Inside your AI agent

Ask an AI tool to crawl a site and it just can — Bluesnake speaks plain text and clean data, the things agents understand.

Claude Code · Codex · Cowork
Built for AI agents

The first crawler your AI can actually drive.

Older crawlers bury their settings in a locked binary file only the app can open. Bluesnake keeps everything in plain text and runs from a single command — so the AI tools you already work in can set up a crawl, run it, and read the results without you lifting a finger.

No plugins, no glue codeIf your agent can run a command, it can run Bluesnake. Nothing to wire up.
Plain-text settings, not a locked fileYour agent reads and edits a crawl's setup the same way it edits any text.

What it does

A thorough crawl, every time.

Point it at a site or a list of URLs. Bluesnake follows the links, records what it finds, and hands you the data to work with.

Whole-site or list mode

Spider an entire site from one URL, or audit a fixed list — including straight from an XML sitemap.

Links, titles & status codes

Every page's title, redirects, and 200 / 404 / 3xx status — plus the link map of how it all connects.

Renders JavaScript

Headless Chrome under the hood, so JS-heavy sites and single-page apps get crawled properly.

Obeys robots.txt

Respects the rules of every site you crawl, with a built-in tester to debug them live.

Exports & sitemaps

Send results to CSV, JSON, JSONL or XLSX — or turn any crawl into a clean XML sitemap.

Compare two crawls

Diff a fresh crawl against an earlier one to see exactly what was added, removed, or changed.

Coming soonBuilt-in SEO checks & scoring — graded issues and priorities, layered on the same crawl engine.
Get started

Your next crawl is one click — or one command — away.

Free, forever. Grab the desktop app, or drop the binary into your terminal in seconds.
