Evensee - Auth Capture

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
