Feature & Specification Comparison
Tools & Capabilities Breakdown
Leapfrog Tools (37)
session_create
Create a new isolated browser session with its own cookies and state. Returns a short session ID (e.g. s_k3m7x1) to pass to all other tools. Each session is a separate BrowserContext — no cookie leakage between sessions. Pool limit: 15 concurrent sessions. Sessions auto-expire after 30 minutes of inactivity. Use keep-alive pattern (periodic navigate or snapshot) for long-running sessions.
session_create_batch
Create multiple isolated browser sessions concurrently — 5-10x faster than sequential session_create calls. Optionally navigate each to a URL. Returns all session IDs. A single reflow positions all windows into a unified grid after all sessions are created.
session_list
List all active browser sessions with their URLs and idle times.
session_destroy
Close and clean up a browser session. Frees a pool slot.
session_save_profile
