Best for
  • AI agents and browser automation projects that need to access heavily protected websites.
  • Developers who need clean, reproducible page extraction and site crawling.
  • Teams that value open-source and auditable stealth technology.
  • Frontend developers who want AI-assisted web debugging and performance analysis
  • Scenarios that need browser automation and performance diagnostics in the same tool
Not for
  • Use cases requiring strict compliance with website terms of service; stealth techniques may violate ToS.
  • Users needing multiple simultaneous personas or highly configurable fingerprints (current CLI limits one persona per launch).
  • Native binaries on macOS or ARM platforms; must run via Docker.
  • Cases that only need to scrape page text without performance analysis or complex interaction (a lighter scraping tool is a better fit)
Required permissions
  • Launches a local Chromium browser process and exposes a CDP endpoint on a local port (e.g., 9222).
  • Assumes full control of the browser via MCP tool calls: navigation, clicks, typing, etc.
  • May access localhost or private IPs, but is SSRF-guarded by default; set TILION_ALLOW_PRIVATE_EGRESS=1 to allow.
  • Requires a local Chrome browser instance to run
  • navigate_page can visit any URL; type_text/fill_form and similar tools can enter arbitrary content into the page
Risks and side effects
  • Use of stealth techniques may violate website terms of service and carry legal risks.
  • Even with fingerprint correction, advanced detection can still flag the browser, especially with datacenter IPs.
  • The browser process consumes CPU and memory; concurrent sessions may impact system performance.
  • Browser automation tools can access and manipulate the content of open pages — use only in a trusted development/test environment
  • performance_start_trace and similar tracing tools continuously record browser activity — avoid leaving them running on pages containing sensitive information
