Yes, XChat is the lite version of 0xchat, while 0xchat is feature-rich.

XChat is the light version of 0xchat, based on Nostr MLS. Each relay corresponds to one circle. Switching circles means switching relays — for example, one relay is for family and another relay is for friends. You can freely switch circles to communicate for different purposes.

Yes, chat messages also use NIP-57. NIP-60/61 aren’t a high priority right now, but they’re on the roadmap.

#0xchat-lite v0.1.4 Update:
1. Only share Permanent key packages invite link (not sent to relays)
2. Key package auto selection prioritizes those received via invite links
3. After accepting an invite, your own key package and profile will be sent back to the inviter
4. Fixed issue with Blossom server failing to upload encrypted files
5. Fixed inability to send link text in messages
6. Improved reliability of relay connection checks

The parameters are attached to the link, and the app parses them to find the user. However, the link will be relatively long.

One reason Google Plus failed was because it was forcibly integrated into other Google services. It claimed to focus on privacy, but in practice, that approach actually worked against user privacy.

Imagine you have a family circle on your family’s private relay, and a friends circle on a relay shared with your friends. Only members of each circle can send and receive messages.
You simply switch to the family circle to chat with family, and to the friends circle to chat with friends.
One identity can join multiple circles, and each circle’s data stays completely separate.

2025-07-16 16:17:20 UTC

- reply

I just published a note. For the circle relay, you can use any public relay or a private relay. All messages within a circle will only be sent to the relay you’ve set for that circle.

Bluetooth P2P mesh mode allows you to communicate with people nearby when there’s no internet connection. It currently interoperates with the bitchat app.

0xchat full version is feature-rich: it supports NIP-17 DMs, NIP-29 group chats, MLS group chats, and more.
0xchat lite version is closer in concept to WhiteNoise: it focuses on MLS group chats, with privacy features like encrypted local database and encrypted media uploads.
Both 0xchat lite and WhiteNoise use nip-ee, so in theory they’re interoperable — but currently there are some technical issues, so cross-app interoperability isn’t fully working yet.

Hi nostr — 0xchat-lite v0.1.0 beta is out!
This is 0xchat lite version, a new lightweight chat client built around MLS — and it’s a bit different from the main 0xchat app.
* Focused, minimal UI for essential conversations
* Separate, platform-native UIs for iOS and Android
* Circle concept: easily switch between multiple circles, each with its own database, relay & file server configuration
**Other privacy features:**
* Encrypted local database
* Encrypted media uploads
* Automatic group ID rotation when members or group info change
* Only connects to relays configured for each circle — no hidden connections
It’s still in beta, so feedback is very welcome!
Try it out and help build a better, privacy-first chat experience on nostr. 🫶

2025-05-31 11:15:46 UTC

MLS stores key packages on the local device, so for state sharing, we need to migrate this part. The remaining events can be synced via relays. I also agree with you — having a private relay is a better choice, especially one relay per group. This is also a key design focus for me in 0xchat lite.

2025-05-21 04:34:10 UTC

- reply

A NIP-29 relay not only forwards messages, but also maintains and synchronizes group state.

-- #0xChat looks abandoned
why? 😂

2025-05-21 02:26:05 UTC

- reply

Unlike notes, group messages rely on group management, and keeping group state in sync across multiple relays is very difficult — if not impossible.

2025-05-21 02:14:02 UTC

- reply

Currently, it's not supported. Personally, I prefer using a single relay for group chats. The main advantage is message stability and consistency.
The downside is the single point of failure — but I believe this can be addressed by implementing a backup and migration mechanism to move the chat history to a new relay if needed.

2025-05-21 02:06:17 UTC

I think this is a problem with fiatjaf's implementation, not a problem with NIP-29 itself.

Not yet, but I can add support in 0xChat Wallet for invoice deep linking. Once Amethyst supports jumping to 0xChat, zapping via your 0xChat wallet would be possible.

It’s not a bad idea imo, but rather a trade-off. Sharing the device key increases the risk of leakage, which goes against the intention of forward secrecy.

I’ve looked into it. Could it be that there is an error during the execution of `checkRelayAuth`? Do you have more specific error logs? The AUTH works fine on my side.
