Features

• Multi-source Library — Unsplash, Pixabay, Pexels, Wallhaven + custom API & local folders
• Visual Tuning — Blur, brightness, saturation, hue adjustments; dark/light theme aware
• Smart Rotation — Time windows, interval auto-change, command palette quick switch
• Performance — Async loading, caching, minimal impact on editor responsiveness

Installation

Requires Obsidian 1.11.4 or later.

Marketplace (Pending)

Currently in Obsidian review queue. Track: obsidian-releases#7359

BRAT

1. Install BRAT
2. Add beta plugin → https://github.com/sean2077/obsidian-dynamic-theme-background
3. Enable in settings

Manual

1. Download main.js, manifest.json, styles.css from Releases
2. Create .obsidian/plugins/obsidian-dynamic-theme-background/
3. Place files inside, restart Obsidian, enable

Quick Start

1. Add Sources — Local images or API providers (Unsplash / Pixabay / Pexels / Wallhaven / Custom)
2. Set Rotation — Interval + optional time windows (morning / day / night)
3. Control — Status bar clicks or Command Palette (dtb) to switch, save & fetch

Status Bar:

• Left Click → Random wallpaper
• Middle Click → Open settings
• Right Click → Save current background

Network and Privacy

• Local images, colors, and gradients work without provider requests. Enabling a wallpaper provider, using a custom JSON endpoint, or applying/saving a remote image can contact the configured third party; that service's terms and privacy policy apply.
• Provider keys, tokens, and every custom-header value are stored through Obsidian SecretStorage. The plugin's data.json contains only non-secret settings and SecretStorage IDs, not those credential values.
• Custom API query credentials must use Secret query parameters. The raw Extra parameters JSON accepts only non-secret string, number, and boolean values; those parameters are appended to the custom endpoint at request time.
• On the first load after upgrading, legacy plaintext credentials are copied to SecretStorage before data.json is replaced. If any secret write fails, the old data.json is left unchanged and plugin startup stops so credentials are not lost or partially migrated.
• Secrets can be shared across plugins or configurations, so deleting a DTB API removes only its reference and does not delete the Obsidian-owned secret.
• The plugin has no telemetry or analytics. Diagnostic logging sanitizes credential-bearing URLs and headers, bounds nested data, and does not intentionally log API keys or tokens.
• Saving a remote wallpaper is an explicit action and writes only to the validated vault-relative folder selected in plugin settings.

Notes

• Optimized for dark themes; light themes may need parameter adjustments
• Uses Obsidian CSS variables — compatible with most themes
• If your theme defines custom backgrounds, choose one or the other to avoid conflicts
