A browser your coding agent
can actually rely on.
The layer that diagnoses the page, verifies every action, and learns from every failure.
Works with Claude Code, Claude Desktop, and Cursor. Node 20+.

Agents don't fail because they're dumb.
Agents don't fail because they're dumb.
They fail because the page lied.
A modal they didn't see. A form that silently rejected them. A re-render mid-click. Splice closes the gap between what the agent intended and what the page actually did.
