开源的 4K 壁纸软件有哪些？

[tuoniaoguoce]

毕竟不能浪费了这块 4K 的屏幕。

[qinghuazs]

花见？

[Magicdove]

我都到壁纸网站下载到本地看

[Frankcox]

unsplash, wallhaven.cc

[julio867]

以前逛 wallhaven ，现在定期到 unsplash 找自己喜欢的，然后批量下载，自己还专门写了一个浏览器扩展方便获取原图地址，然后迅雷批量下~~😄

[xiangshuaaaa]

@julio867 扩展发布了嘛，白嫖下（ bushi ）

[julio867]

@xiangshuaaaa 注册开发者比较麻烦，目前仅自己在本地使用~

之前放了一个 wallhaven 的在 github 上：
https://github.com/zoujia/WallhavenAssistant （写的不好，只保证了能用😅）

unsplash 的抽空再把它放到 github 上吧~

[since2021]

偶尔去 reddit 上自己找

[mohuani]

https://paper.meiyuan.in/ 我用的这个

[Weyeeep]

只用过 unsplash

bing wallpaper 每天换新

[565656]

win11 自带了 设置 windows 聚焦每天自动换

[timothyye]

做过一个 bing wallpaper 的开源项目
https://github.com/TimothyYe/bing-wallpaper

[fuyun]

https://www.ifuyun.com/wallpaper 除了壁纸，还有壁纸背后的故事，支持中英文，支持全文搜索。
前台开源（ https://github.com/ifuyun/ifuyun.com ），API 闭源。

[JensenQian]

壁纸我用的 steam 上 19 块小红车
不过不认识的别乱下，最近在闹赛博梅毒

[senzyo]

那得推荐一下 https://github.com/rocksdanister/lively ，完全能替代 Wallpaper Engine

楼上的好东西，感谢分享

pexels 和 unsplash 有提供 API, 你自己註冊一個開發者帳號(免費), 然後寫一個腳本自動獲取就可以了.

我自己是使用 shell + crontab 實現定期獲取隨機圖片並設置爲桌面背景.
