Evensee - Auth Capture

About

Chrome extension that captures authentication headers from browser network requests with one click. Ready-to-paste JSON for Playwright & AI coding agents.

The Problem
When working with AI coding agents (Claude, Cursor, Copilot) that can browse the web via Playwright, they can't access sites where you're logged in. Sharing passwords is unsafe.

Evensee captures your auth headers in one click and formats them as ready-to-use JSON for page.setExtraHTTPHeaders() or context.addCookies().

Features
One-click capture — click Capture, page reloads, headers are captured
Multi-origin grouping — headers grouped by actual request domain (API, CDN, etc.)
Smart filtering — tracking cookies & analytics domains automatically excluded
Auto-stop — stops listening after strong auth headers are captured
Copy as JSON — ready to paste into Playwright scripts or AI agent prompts
Collapsed view — shows max 3 headers per site, expandable with "Show more"
Security
Memory only — headers stored only in service worker memory, never persisted to disk
Auto-clear — configurable timer (5m / 30m / 60m / manual)
Clipboard auto-clear — clears clipboard after copy (30s / 2m / off)
Zero network — extension makes zero outbound requests, ever
On-demand only — no background monitoring, listeners active only during capture
Domain + tab scoped — captures only for the specific tab you clicked
