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
Anyone can host a site. Just keep it up for like a month without a pause so that it can be discovered.
Then go to a domain registrar and get a domain name. I2p sites have BASE32 names, kinda like onion addresses. But they can also use shorter names like postman.i2p
If you register such a name, the site will become more discoverable as those registrars likely share the sites, you might appear in some lists, people connect to you, add you to their address book and forward stuff to you.
Neat, I might set up one of my older, currently unused phones to be my host. As soon as I figure something I want to share around
If you want to host stuff, you probably want Termux. It is its own distribution but you may want to run a Debian proot inside Termux, which will have way more software and maybe also more reliably and fast security updates (heard that was a problem in Termux)
