Capability parity
Every method each SDK exposes is tested (see coverage). Surface differs by
design: Python additionally ships a full MCP client (b4n1web.mcp), so it
covers the whole tool surface; JS/C#/Java/Ruby/PHP/Go wrap the CLI binary
(core flows). Cells below are measured against each SDK's actual source
(b4n1-web 0.16.0), not aspirational: explicit rounding — ✓ implemented ·
· not implemented · mcp available through the bundled MCP server.

Full parity = one MCP client per SDK (JS/CS/Java) — tracked as tasks; the Ruby/PHP/Go interaction gaps (click/type, device emulation, file transfer, cookies/frames) are their own parity tasks.
Browser Modes
Mode | Description | RAM | Startup |
Light | HTTP fetch + HTML parsing | ~15MB | Instant |
JS | Light + JavaScript extraction | ~15MB | Instant |
Render | Full Chromium + screenshots | ~100MB | ~2s |
Features
35 MCP tools for AI agent integration
4 language SDKs (Python, JS, Java, C#) with bundled binary
Self-contained binary ~12MB, no dependencies
Static linking (musl) — works on any Linux, no glibc required
Three modes: Light (instant), JS (scripts), Render (Chromium)
Security shield: domain filtering, safe browsing
Network interception: block resources, mock responses
MCP Server: stdio transport, no port needed
Link extraction: get_links MCP tools + getLinks() in every SDK (one-shot fetch without a browser instance)
--licenses flag: prints the bundled license + third-party notices, no key required
