claude-down

is claude down (again) (yes). booga check, you no cry.

claude no work? maybe you. maybe anthropic. (probably anthropic.) booga look two place same time:

• status.claude.com — what anthropic admit to.
• Downdetector — what everyone else screaming about, usually first.

or just watch the page

claude-down web
# or
claude-down site

how use

words for human

status give indicator, lil description, details from both place.

claude-down status

words for robot

json for your scripts and your little monitoring guys.

claude-down status --json

no words, just number

exit code always tell truth (see the numbers), output or not. slap -q/--quiet in CI when you only care about number.

claude-down status -q

pick your place

default check uses Anthropic and Downdetector. use subcommand or --source; --source eat commas and repeats. Downdetector may report unavailable if Cloudflare challenge automated checks.

# subcommand
claude-down anthropic
claude-down downdetector

# flag
claude-down status --source anthropic
claude-down status -s downdetector

# many
claude-down status --source anthropic,downdetector
claude-down status -s anthropic -s downdetector

pick your model

only show incident/component that name model you care about. summary AND exit code shrink to just those. like --source, --model eat commas and repeats, and every model got shortcut flag.

# shortcut
claude-down status --opus --sonnet

# --model, commas and/or repeats
claude-down status --model opus,sonnet
claude-down status -m opus -m sonnet

models: opus, haiku, sonnet, mythos, fable.

use in browser

browser-safe door, anthropic only (downdetector need real chromium, no work in browser).

import { checkAnthropic } from "claude-down/browser";

const result = await checkAnthropic();

if (result.kind === "ok") {
  console.log(result.summary.status.description);
  console.log(result.summary.status.indicator);
  console.log(result.summary.incidents);
  console.log(result.summary.components);
} else {
  console.error(result.reason);
}

the numbers

exit code = how bad. set every run (not just --quiet), worst source win.

Code	Vibe	what happen
0	all good	everything work. go back to your life.
1	meh	minor thing, or anthropic got live incident.
2	cooked	major/critical outage, or downdetector say claude down.
21	who knows	every source booga try was unreachable.

source booga no reach = unknown, NOT down. 21 only when EVERY source dead, so one flaky downdetector scrape no ruin your day.

who do all this

booga no write flag parser. booga no write --help, tab-complete, json mode, exit codes. all that dreamcli. booga just point at anthropic and shitpost.

you want make own CLI look this clean? → dreamcli

hack on it

bun install   # setup
bun run build # build
bun test      # test
