### [Ebrowser](https://github.com/torappinfo/ebrowser) as alternative to [uweb browser](https://github.com/torappinfo/uweb)
Ebrowser is the minimal browser with the philosophy of [Android uweb browser](https://gitlab.com/jamesfengcao/uweb).

- lightweight (less than 20k bytes) without bundled electron.
- much less memory footprint than edge/chrome browser and highly performant.
- keyboard (command line) friendly.
- 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.
