Stealth - Secure, Peer-to-Peer, Private and Automateable Web Browser/Scraper/Proxy

Tholian® Stealth is the Web Browser/Scraper/Proxy for Automation and the Web of Knowledge.

Its design goals are increased Privacy, increased Automation, adaptive Semantic Understanding and efficient bandwidth usage, no matter the cost.

It is built by a former contributor to both Chromium and Firefox, and is built out of personal opinion on how Web Browsers should try to understand the Semantic Web.

Stealth empowers its Users, not Website Developers that could (,will ,and did) abuse technologies to compromise the freedom and rights of Web Browser End-Users.

Downloads / Releases

Stealth is currently in the Prototype Stage. Non-Developing Users won't enjoy it much, as things are quite buggy and incomplete for the moment.

However, due to the concept of using node.js and focussing on a privacy-oriented audience, Stealth will initially be released for MacOS and GNU/Linux.

Features

Stealth is both a Web Scraper, Web Service and Web Proxy that can serve its own User Interface ("Browser UI") that is implemented using Web Technologies.

It is secure by default, without compromise. It only supports DNS via HTTPS, and uses explicitely https:// first, and fallsback to http:// only when necessary and only when the website was not MITM-ed.
It offers intelligent Error Page wizards that guide the user through scenarios when things are broken, from no domain resolved to download snapshot via web archive.
It is peer-to-peer and always uses the most efficient way to share resources and to reduce bandwidth, which means downloaded websites are readable even when being completely offline.
It uses blacklist-based Blockers that is on feature-parity with AdBlock Plus, AdGuard, Pi-Hole, uBlock Origin and uMatrix (in the sense of "all of the above").
It uses Optimizers to render only the good parts of HTML and CSS. These Optimizers make sure that no Client or Peer ever receives any malicious or unwanted content, and it is written on-filesystem-cache (which is shared later to other peers) to ensure that particularly. All Optimizers are applied across all Site Modes, and the Site Modes decide what content or media is included.
It uses whitelist-based Site Modes that decide what to load, with incrementally allowed features (or media types). By default, Stealth will load nothing. The Site Mode next to the address bar decides what is loaded.
It uses whitelist-based Site Beacons that allow specific elements on a Site to be extracted as Knowledge - which in return help to train the Browser to understand future similar Sites on the web more easily. This can be seen as a learning mechanism that is similar to the "Reader Mode" in other Browsers, but whilst delivering the cleaned content to all connected Clients and Peers (including Smartphones and Tablets).
It never requests anything unnecessary. The cache is persistent until the user tells it to refresh the Site manually (or a scheduled Download task runs for that URL).
It uses trust-based Peers to share the local cache. Peers can receive, interchange, and synchronize their downloaded media. This is especially helpful in rural areas, where internet bandwidth is sparse; and redundant downloads can be saved. Just bookmark Stealh as a Web App on your Android phone and you have direct access to your downloaded wikis, yay!
It can double-function as a Content-Auditing and Content-Filtering Web Proxy inside other Web Browsers, which allows corporate-like setups with a shared peer-to-peer Cache and a local Web Archive of the Internet.
It has intelligent error handling. In case a website is not available anymore, the stealth:fix-request error page allows to download websites automagically from trusted Peers or from the Web Archive.
This ain't your Mama's Web Browser. It completely disables to load ECMAScript in order to improve Privacy. Stealth also does not support Web Forms or any Web API that could potentially send data to the website.
Stealth can be scripted as a Web Scraper inside node.js. The Browser is completely free-of-DOM, so every single task and interaction that the Browser UI does can be implemented in an automateable and programmable manner, even remotely through trusted Peers using Stealth's peer-to-peer network services.

Stealth Guide (for Hackers?)

The Guide is currently meant for Developers that are new to the Project. It explains all necessary topics to quickly get started to hack around with Stealth and modify it to fit your needs.

A User's Guide probably will arrive at a later point in time, as Stealth currently has no public release yet.

Quickstart

If you don't wanna deal with the native build toolchain, this is how to get started as quickly as possible:

Install node.js version 10+.
Install Ungoogled Chromium version 70+.
(Only MacOS) Alternatively Install Safari version 12+.
(Only Linux) Alternatively Install electron version 8+.
(Only Linux) Alternatively Install gjs and WebKit2 GTK version 4+.

git clone https://github.com/tholian-network/stealth.git;
cd ./stealth;

# Make everything
node ./make.mjs;

# Start Stealth Service (optional debug flag)
node ./stealth/stealth.mjs --debug=true;

# Open as Progressive Web App
node ./browser/browser.mjs;

IMPORTANT: On Android, Stealth can be used by visiting the URL and bookmarking it as a Web App. The Stealth Icon will appear on your home screen, and it will behave like a native offline-ready mobile app.

Roadmap

The current roadmap is a mixture of the /issues section on GitHub/GitLab and the features that are going to be implemented in the near future which are put together in the ROADMAP.md file.

As this project in its current form is highly experimental software, those features can change very rapidly; and lead to at least partial refactors of the codebase as well.

If you have Problems, Suggestions or Ideas that would fit into Stealth, please open up an Issue and we'll be happy to talk about it :)
