Pass secrets through your shell environment rather than committing them into a config file.

What tools does DLBrowser expose?

This server runs as a local package. We only query remote servers for their tool list — asking this one would mean executing it, so its tools are listed in the documentation below.

What the code can do

Source analysis currently covers npm packages only. This server ships as a Python package, which needs a different parser.

Before you install

Signals gathered from the source repo and package registry — not a safety verdict.

What it can reach

Runs code on your machine — Executes as a local process with your user's permissions, including filesystem access.
Downloads at launch — The package is fetched from its registry each run unless you pin a version.

Documentation

Full README

DLBrowser

Your AI agent is blind to the half of the web that fights back.

Cloudflare, captchas, and JavaScript walls block the tools agents use to browse — silently. DLBrowser is the one that gets through. One line. Self-healing. Metered to the credit.

bash

npx dlbrowser connect --key dlb_xxx

*Wires DLBrowser into Claude Code, Cursor, Windsurf, Cline & Codex in one command. Your agent gets 11 web tools that actually reach the page.*

The 60-second try

bash

pip install dlbrowser
dlbrowser fetch https://example.com

Every fetch tells you which backend got through and how long it took — because the engine picks the cheapest one that works and only escalates when a site fights back:

json

{ "success": true, "backend": "curl_cffi", "load_time": 0.03, "blocked": false }

And every run is metered against a plan, in the open — no surprise invoice:

json

{ "plan": "scout", "remaining_daily": 497, "remaining_monthly": 2497,
  "upgrade_url": "https://dekryptlabs.github.io/dlbrowser/pricing.html" }

That's a real response from the live gateway. Start free — 2,500 credits, no card.
