The plugin is a benign bar widget that fetches CNN's Fear & Greed index once daily via a fixed curl command, caches the result locally, and displays it. The deterministic scan flagged sudo/apt-get in the CI workflow, but that is only for GitHub Actions and is not part of the installed plugin. No malicious, obfuscated, or harmful behavior was found in the runtime code.

  • The CI workflow uses sudo apt-get, but this runs only in GitHub Actions and does not affect users installing the plugin.
  • The plugin uses a browser-like user agent and referrer to access CNN's undocumented endpoint, which is a policy/availability concern but not a security risk.
How this check works

This review combines the deterministic scan (the rule-based results above) with an independent look at the plugin's code by a language model. The model reads a trimmed sample of the repository's files, the manifest, and the README, then gives a plain-language risk level and a recommendation: install (no notable danger), review (look closer first), or avoid (clearly dangerous).

It runs on the same analyzed commit as the deterministic scan and is strictly advisory — it is not a security guarantee and never blocks a plugin by itself. A human moderator still reviews plugins before they are listed.

AI advisory only — automated analysis, not a security guarantee.

Market Fear & Greed for Omarchy

An Omarchy bar widget for the US stock-market Fear & Greed Index published by CNN.

Market Fear & Greed panel

Animation showcase

These representative readings use the default Full animation mode. Neutral is intentionally still, while Fear and Greed become more intense toward their extremes.

Extreme Fear · 10 Fear · 35
Extreme Fear with a tall, turbulent fire bed Fear with a lower moving fire bed
Neutral · 50 Greed · 65
Neutral state without particles Greed with falling coins and banknotes
Extreme Greed · 100
Extreme Greed with dense falling coins and banknotes

What it shows

  • The latest index as a color-coded gauge.
  • A glowing, continuously moving fire bed for Fear readings.
  • Tumbling gold coins with occasional fluttering banknotes for Greed readings.
  • Previous close, one week ago, one month ago, and one year ago as colored numbers.
  • CNN's publication timestamp so weekends and market holidays are clear.
  • The last good value when CNN is temporarily unavailable.

Left-click the bar value to open the panel. Right-click the bar value, click Source: CNN, or press Enter/Space while the panel is focused to open CNN's official index page. Escape closes the panel.

The widget's Animation setting controls the effect:

  • Full is the default playful animation.
  • Subtle halves the particle rate and lowers the opacity.
  • Off keeps the gauge completely static.

Neutral readings do not show particles. Animation stops and clears as soon as the panel closes, so the bar does no continuous particle work in the background.

There is deliberately no manual refresh. The plugin makes at most one data request in any rolling 24-hour period, including across shell and machine restarts.

Install

Requires Omarchy 4 (Quattro), Qt SVG, curl, and flock from util-linux. These are part of a standard Omarchy installation.

omarchy plugin add https://github.com/davidojedalopez/omarchy-fear-greed.git --enable --yes

The widget defaults to the center section. Move it with Omarchy's bar settings if you prefer another position.

Update

omarchy plugin update io.github.davidojedalopez.fear-greed

Remove

omarchy plugin remove io.github.davidojedalopez.fear-greed --yes

Cached public index data is stored separately at:

${XDG_CACHE_HOME:-$HOME/.cache}/omarchy/plugins/io.github.davidojedalopez.fear-greed/

It may be deleted after removing the plugin.

Data, privacy, and network behavior

The widget makes one HTTPS request per 24 hours to CNN's first-party data host:

https://production.dataviz.cnn.io/index/fearandgreed/graphdata

The endpoint currently rejects ordinary API clients with HTTP 418, so the request includes a browser-like user agent and CNN's index page as its referrer. The URL, headers, timeouts, and response-size limit are fixed in the source; none are user-controlled.

The plugin sends no credentials or local data. It has no telemetry, analytics, listeners, background services, or privileged operations. It stores only the normalized public score, comparisons, timestamps, and last-attempt time in the local cache. The full CNN response and command errors are not persisted.

Important source limitation

CNN does not publish a supported developer API or redistribution license for this index. The endpoint above is an internal feed used by CNN's page. It may change, return HTTP 418, block automated clients, or disappear without notice. Fetching once daily reduces load but does not make the integration supported by CNN.

This is an unofficial third-party plugin. It is not affiliated with or endorsed by CNN, Warner Bros. Discovery, Omarchy, 37signals, or the Omarchy Plugins community marketplace. CNN owns its names, marks, index, and associated rights. The MIT license in this repository covers only this plugin's original code.

The index and this plugin are informational only and are not financial or investment advice.

Troubleshooting

  • -- means no valid cached reading is available yet.

  • stale means the panel is showing the last good reading after a failed daily request.

  • A blocked request is reported as CNN blocked the data request; the plugin will not attempt another request for 24 hours.

  • Validate an installation with:

    omarchy plugin validate "$HOME/.config/omarchy/plugins/io.github.davidojedalopez.fear-greed"
omarchy-shell shell ping
