Snitch any URL as Markdown. Even Cloudflare/anti-bot protected. Ready for LLM.
Use snitchmd when:
- you need to feed a page to an LLM and raw HTML is too noisy for the context window;
- a plain
curlorfetchreturns an empty shell because the page is rendered by JavaScript; - the site is gated by Cloudflare, reCAPTCHA, or similar anti-bot checks;
- you want one tool that handles all three without picking a scraping engine.
snitchmd https://example.comThat's the whole job. Markdown to stdout, ready to paste into a prompt, a note, or a RAG pipeline.
Under the hood, snitchmd chains two existing projects so you don't have to: CloakBrowser renders the page past anti-bot checks, and rs-trafilatura strips it down to readable Markdown. It's a small Docker wrapper — no new scraper, no new engine.
Disclaimer: via CloakBrowser, snitchmd looks like a real browser — Cloudflare and other detectors don't flag it as a bot (test results). It can't solve the "click all the traffic lights" kind of CAPTCHAs (reCAPTCHA v2, hCaptcha).

Each successful fetch is cached on disk by URL + relevant flags. Re-running the same command reads from cache (no browser launch, no extraction).
- Location:
${XDG_CACHE_HOME:-$HOME/.cache}/snitchmd/on the host (mounted into the container as/cache). - Bypass and refresh a single URL:
snitchmd --no-cache https://example.com. - Wipe everything:
rm -rf ~/.cache/snitchmd. - Output-only flags (
--json,--html-output) don't affect the cache key, so the same URL is cached once across them.
docker pull syabro/snitchmdWhen the tool itself or its install is broken. Content-shape problems (empty output, missing sections, too much chrome) are pipeline-tuning decisions — see snitchmd --help.
| Symptom | Fix |
|---|---|
snitchmd: command not found |
Re-run the install one-liner; ensure ~/.local/bin is on PATH |
Docker is not installed or not in PATH |
Install Docker — https://docs.docker.com/get-docker/ |
Docker is installed, but the Docker daemon is not running |
Start Docker (Docker Desktop on Mac/Windows; the Docker service on Linux) |
permission denied on the Docker socket |
Add your user to the docker group, then re-login (Linux) |
| Image pull fails on first run | Check connectivity; retry with docker pull syabro/snitchmd |
--platform linux/amd64 warning on Apple Silicon |
Expected — runs under Rosetta emulation (slower but works) |
| Cache directory not writable | Fix ownership of ${XDG_CACHE_HOME:-$HOME/.cache}/snitchmd, or delete it to let it recreate |
Exit codes. 0 success, 1 runtime error (browser, network — full message on stderr), 2 extraction returned empty content (page was a loading shell, hit a wall, or has no main content).
Use --json when you need metadata such as the final URL, page title, extraction quality, and Markdown length:
snitchmd https://example.com --jsonsnitchmd --helpOpen ideas live in tasks.md in mdtask format. Browse with pnpx mdtask list (or any markdown viewer).
