BlurShield

BlurShield automatically blurs sensitive information on every website you visit. Built for developers, cloud engineers, and anyone who does screen sharing, demos, or recordings. Supports Azure, AWS, GCP, OpenAI, and Anthropic patterns out of the box, plus general sensitive data like emails, IP addresses, phone numbers, street addresses, credit cards, and API keys. Key features: - Active on all pages by default, no per-site setup needed - Multi-cloud support (Azure, AWS, GCP, OpenAI, Anthropic) - Framework-safe - uses CSS blur on parent elements, never modifies the DOM - Add your own custom keywords or regex patterns - Personal info protection - your emails and IPs are always masked - Adjustable blur intensity with optional reveal on hover - Per-site bypass list for sites where masking isn't wanted - Import/export your configuration as JSON - No data collection, no analytics, no network requests - Runs entirely in your browser Built as a Manifest V3 replacement for azure-mask, extending beyond Azure to cover all major cloud providers and general sensitive data.
