ebrowser

Ebrowser as alternative to uweb browser

Ebrowser is the minimal suckless browser with the philosophy of Android uweb browser.

• lightweight (less than 20k bytes) without bundled electron.
• much less memory footprint than edge/chrome browser and highly performant.
• keyboard friendly with vim-style keymaps and command line support in address bar.
• global redirection to bypass censorship.
• user scripts at will. Ex. pressing "tr" to translate the page (need mapkeys.json config).
• customizable.

Note: Usually electron apps are heavyweight as they use browsers for simple things. Ebrowser uses core chromium effectively and very lightweight. Recommend to install electron separately.

Install (for Windows, MacOS and Linux)

npm install ebrowser

Run ebrowser

electron ~/node_modules/ebrowser
