Valetkey, the valet key for coding agents

valetkey.dev Observed source

Editorial interest 79/100 Selection signal · not a rating of the site

A developer tool that lets coding agents use short-lived signed-in application sessions without exposing passwords or secret keys.

Landing page captured for the 2026-08-25 issue.

Field notes

Valetkey models authenticated browser access as a scoped handoff rather than a credential handoff. Developers define personas, keep provider secrets in an age-encrypted vault, and run `valetkey login` to produce a session for a managed Chrome profile or a Playwright storage-state file. The page also describes an MCP path for Claude Code, Codex, and Cursor, with a stated 60-minute expiry, development-origin cookie pinning, and audit logging.
