Common questions

Is B4n1Web safe?

It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed 16 days ago, and the latest version (0.12.2) reached the registry 4 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js, Python (uv), .NET on your computer.

What can I use instead?

🖥 Platform Support

8 pre-compiled binaries — works everywhere:

Platform	Architectures	Binary
Linux	x86_64, aarch64, i686	`musl` (static, no glibc)
macOS	x86_64, arm64	`universal`
Windows	x86_64, arm64	`MSVC`

Quick Start

# Install the binary

curl -sL https://raw.githubusercontent.com/B4N1-com/b4n1-web/master/scripts/install.sh | bash

Or use your preferred package manager

pip install b4n1-web npm install b4n1-web dotnet add package B4n1Web

Java: add dependency from Maven Central

from b4n1web import AgentBrowser

browser = AgentBrowser() page = browser.goto("https://example.com") print(page.markdown) browser.close()

SDK Matrix

Language	Package	Version	Binary
Python	`b4n1-web`	0.16.0	Bundled (musl)
JavaScript/TypeScript	`b4n1-web`	0.16.0	Bundled (musl)
Java	`com.b4n1:b4n1-web`	0.16.0	Bundled (musl)
C# (.NET)	`B4n1Web`	0.16.0	Bundled (musl)
Ruby	`b4n1-web`	0.16.0	Resolver (env/system/PATH)

Go	`b4n1-web/sdks/go`	0.16.0	Resolver (env/system/PATH)

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.

Capability	Python	JS/TS	C#	Java	Ruby	PHP	Go
goto (light / js / render) + page screenshot	✓	✓	✓	✓	✓	✓	✓
wait (`--wait-for` / waitForSelector)	✓	✓	✓	✓	✓	✓	✓
click / typeText	✓	✓	✓	✓	·	·	·
links (Page) + find-links-by-text	✓	✓	✓	✓	✓	✓	✓
getLinks (browser) / one-shot fetch	mcp	✓	✓	·	·	·	·
evaluate (JS execution)	✓	·	·	·	✓	✓	✓
viewport / user-agent / emulate-device	✓	✓	·	·	·	·	·
upload / download / frames / cookies	✓	·	·	·	·	·	·
binary version query (bundle == SDK)	✓	✓	✓	✓	·	·	·

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
