SmsForwarder
Monitors Android mobile phone text messages, calls, and notifications
SmsForwarder is an Android application designed to monitor incoming communications such as SMS messages, phone calls, and app notifications, and then automatically forward them to configured destinations based on user-defined rules, making it ideal for remote monitoring, backup, or automation scenarios. Users can set custom logic so that certain messages or notifications trigger forwarding to group chat bots (like DingTalk or enterprise WeChat), webhook endpoints, email, push services (PushPlus, Bark), Telegram bots, and other channels, allowing flexible integration with communication workflows. In addition to basic forwarding, the app’s rule-based engine can filter messages, enabling selective forwarding based on content, sender, or event type, and it can even push details like call logs or device battery status. The tool’s functionality extends to remote control features, which allow a paired server or client to query messages, calls, contacts, and more. -

Goofy
Desktop client for Facebook Messenger
Goofy is a macOS client for Facebook Messenger. But unlike most other clients, it does not use any of Facebook's APIs, but is basically a single-site browser that injects a little CSS and JS into messenger.com to make it a little more app-like. Feel free to create issues on this repo for feature requests of any kind. However, some features may not be possible due to the way this application is working. Also, I don't want this to be a feature-bloated monster, but a slick and small app. Depending on the number of contributors and the progress of this app, I will schedule releases from time to time, which will then be distributed on goofyapp.com. To debug, there's a VSCode launch.json that can be used to debug the Electron app. To debug the Facebook JavaScript changes you'll need to use the Chrome Web Inspector. -
