On Android/GrapheneOS, Firefox/Mull/variants is the only browser with the needed proxy settings to use with i2p.
After a bit of searching, it works very well!
As i2p servers you can use “i2p”, “i2pd” (more minimal but more efficient) or “InviziblePro” which bundles some implementation of i2p.
I am using i2pd currently, and it works well.
Installed the apps with Obtainium
- Mull from the DivestOS F-Droid repo
- i2pd from the purplei2p F-Droid repo
- MullvadVPN from Github, Orbot from the guardianproject repo (as fallback if clearnet sites are used)
The browser can open .i2p and clearnet sites, using a little hack:
network.proxy.no_proxies_on to !.i2p
What is I2p?
https://en.wikipedia.org/wiki/I2P
I2P and Tor both aim to provide anonymous internet browsing but differ in their architectures and methods. Tor (short for The Onion Router) uses a system of layered encryption to route internet traffic through a network of volunteer-operated servers. This creates a series of encrypted layers (hence the onion analogy) that mask the user’s IP address and data content from any would-be observers.
In contrast, I2P uses a garlic routing technique, where multiple messages are bundled together into a single encrypted packet. This method enhances privacy by making it more difficult for anyone to analyze the traffic and link the data back to specific users.
Also, Tor supports access to the open internet (clearnet), while I2P only allows access to websites and services (known as eepsites) within its own networks. Outproxies, which are similar to Tor exit nodes, can be used to access the clearnet with I2P. However, this reduces privacy as your data leaves the network and is a less common use case.
