Developer builds Chrome extension to prevent screen-share mishaps and data leaks

·23 views

A developer created ScreenGuard, a Chrome extension, after a viral post described a founder accidentally opening an adult website while screen-sharing with a CEO. The extension works locally in the browser and offers two core features: warnings before potentially risky or phishing-style links open, and a screen-share protection mode that blurs sensitive data such as API keys, email addresses, and payment details. The tool is designed to intervene only when necessary, avoiding constant permission prompts that could frustrate users during normal browsing. ScreenGuard is free and currently at version 1.0.15, with the developer actively seeking feedback from professionals who frequently share their screens. The creator is targeting developers, founders, educators, and sales teams, and wants to refine the product before expanding its feature set.

Scaffoldr Proposes Product-Based Project Starters Over Stack-Based Scaffolding

The author argues that existing tools like create-next-app, create-t3-app, and SaaS starter kits organize project setup around technology stacks or fixed product templates. Modular scaffolders ask which technologies to use, while starter kits lock developers into someone else's choices, which can drift over time. The proposed Scaffoldr tool would instead let developers specify a product type, such as ticketing, with swappable modules for payments, databases, auth, and email. The author notes that African payment providers like Paystack are often overlooked, and the project is not yet built, with maintenance and developer interest remaining open challenges.

Yonto Player moves its source contract into JavaScript plugins on QuickJS

The Yonto Player TV app connects to media servers and folders through a single ContentSourceAdapter interface. Its source contract began as an HTTP API backed by a hosted service, but that required someone to run and update a middle layer whenever a media server changed its fields. The developer kept the contract's JSON shapes as the single definition and made transport an implementation detail, allowing sources to run as JavaScript plugins inside the app. Each plugin is one file whose manifest, declaring its identity and permitted hosts, is read as plain text, and it exposes required functions such as search and getMediaList. Plugins reach the outside world only through a restricted global object, which limits them to requests, configuration, a small cache, logging and parsing helpers.
