| 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.
| - Scenarios where an AI assistant needs to actually drive a browser to complete a task
- Web automation testing and end-to-end verification
| - 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.
| - Simple static-text scraping (a lightweight scraper is a better fit)
- Environments sensitive to browser resource usage that can't run a full browser engine
| - 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 installing and running a browser engine (Chromium/Firefox/WebKit) locally or on a server
- browser_navigate can visit any URL; browser_evaluate can run arbitrary JavaScript in the page context
| - 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_evaluate executing arbitrary scripts carries risk if a malicious page is visited — restrict to trusted sites or an isolated environment
- Long-running browser instances consume significant memory and CPU
| - 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
