Bearer Token Grabber

About

Bearer Token Grabber captures Bearer tokens from HTTP requests on any webpage — no DevTools required.

Built for developers who work with authenticated APIs, OAuth flows, and JWTs daily. Stop manually digging through Network tabs.

TOKEN CAPTURE
• Automatically intercepts fetch() and XMLHttpRequest calls
• Captures Bearer tokens from Authorization headers
• Smart filtering ignores SignalR, WebSockets, analytics, and health checks

JWT INTELLIGENCE
• Decodes JWT payload automatically — view claims inline
• Color-coded expiry indicator (green/orange/red)
• Displays issuer, subject, audience, scopes, email, and more

COPY & EXPORT
• Copy Token — just the JWT value
• Copy with Bearer — includes "Bearer " prefix
• Copy as cURL — full curl command with Authorization header and URL
• Keyboard shortcut: Ctrl+Shift+B / Cmd+Shift+B

PRODUCTIVITY
• Auto-copy mode — new tokens copied to clipboard automatically
• Token history — last 10 unique tokens per tab
• Domain grouping — filter by API domain
• Badge notification when new token captured
• Dark and light theme

PRIVACY
• All data stays in your browser — nothing sent externally
• Session storage only — tokens cleared when tab/browser closes
• No analytics, no tracking, no telemetry
• Open source (MIT License)

PERMISSIONS EXPLAINED
• scripting: Read captured tokens from the active tab
• activeTab: Identify the current browser tab
• storage: Remember your theme and auto-copy preference

Perfect for API development, OAuth debugging, token monitoring, and daily development workflows.
