[I2P](https://geti2p.net/) is another anonymity network and alternative to Tor.Tails used to include I2P until 2017. We removed I2P in [[Tails 2.12|news/version_2.11]] because it was too costly to maintain.
We have no plans to add I2P back in Tails because I2P hasn't yet become popular and usable enough to matter to our [[target audience|contribute/personas]].
