Description

Owl Browser is a high-performance, self-hosted Chromium and CEF engine built for AI agents. Rather than screenshots or DOM trees, OwlMark renders pages as compact, handle-addressable views so models browse reliably. Features built-in MCP server, natural language automation, 256 parallel contexts, and C++ source-level fingerprint spoofing. Commercial software with $0.99 14-day trial; free companion build owl-light is a Playwright drop-in (not open source).
