I made a Stream Deck plugin that throws confetti, fireworks and a full-screen "GAME OVER" over your Mac screen. Native, 200 KB, no extra apps

Hey all, sperandev here. I built Screen FX, a Stream Deck plugin that puts effects right on top of whatever's on your screen. Press a key and: - 🎉 Confetti: side cannons, burst, rain or fireworks, with custom palettes - 🔥 Stage pyrotechnics: flamethrowers, cold sparks, fire columns. Hold the key to keep it firing - 🛑 Full-screen sign: a "GAME OVER" (or any text) stamp with a voice announcer (arcade, demonic, movie trailer, robot, megaphone) - 💸 Money rain, ❤️ hearts, 🐾 flying critters

AI 分析

痛点:Stream Deck/macOS 用户想要一键在真实屏幕上叠加彩带、烟花、GAME OVER 等特效,但现有方案依赖 OBS 浏览器源或 Electron 后台应用,笨重且不能覆盖任意应用。

目标用户:Stream Deck 用户、直播主、教师、会议演示者、内容创作者,尤其是 macOS 用户。

证据:It's on the Elgato Marketplace for $3.50 one-time. / most overlay tools need OBS browser sources or an Electron app running in the background. This one is a single native Swift binary (~200 KB, Apple Silicon + Intel).

变现:一次性付费 $3.50 上架 Elgato Marketplace;可扩展为 Pro 版、特效包订阅、自定义品牌广告模板或企业会议/课堂授权。

MVP:用 Swift 写一个 macOS 透明点击穿透悬浮层 + Stream Deck SDK 插件,先支持 3 种特效(彩带、GAME OVER 文字、计时器),内置合成音效,打包约 200KB 原生二进制,上架 Elgato Marketplace 定价 $3.50。

竞品:OBS 浏览器源/插件、Streamer.bot、Muxy、Own3d 特效、Elgato Marketplace 上其他 Stream Deck 特效插件

摘要:sperandev 发布 Screen FX,一个 macOS 原生 Stream Deck 插件,可在任意屏幕应用上叠加彩带、烟花、GAME OVER、计时器等特效,单文件约 200 KB,无 Electron/OBS。已在 Elgato Marketplace 以 $3.50 一次性售卖,面向直播、会议、课堂和录屏场景。
