The latest version of this list is always on Tangled.
Community Chat
Armada
https://armada.buzz
The best of Nostr messaging in one client. NIP17 DMs, NIP29 relay communities, and Concord secure communities.
Notable mention is Vector (https://vectorapp.io), the origins of the Concord protocol. They’re working on version 0.5 which will bring it to near feature-parity with Armada. Right now Vector is more of a traditional messenger than a community chat, but 0.5 will make it great for communities too.
- Platforms: web, windows, macos, linux, android
- PWA enabled for iOS, including WebPush
- Calling: Voice, Video, Screenshare
- Calling is available for all Concord communities; NIP29 channels must have LiveKit enabled by the server. Self-hosting a voice server is an option for Concord communities.
- Embedded Content: Images, Videos, GIFs (requires filetype)
- Pro-Features: No Personal Information Required, Open-Source Software, Decentralized, End to End Encrypted (NIP17 and Concord only)
- Anti-Features: —
- Special Features
- Ditto Themes: Customize the colors of your experience. Themes created/activated in Soapbox’s sister app Ditto will carry over to Armada, however themes activated in Armada will not carry over to Ditto (you can save a theme from Armada to activate in Ditto later).
Chatto
https://chatto.run
A Discord-like app where every server is a literal server.
- Platforms: web
- The web app can function as a PWA
- Calling: Voice, Video, Screenshare
- Embedded Content: —
- Pro-Features: Open-Source Software, Decentralized, Self-Hostable
- Anti-Features: —
DEN Chat
https://denchat.top
Another Nostr-based community messaging app, with some interesting special features and integration into the wider Nostr ecosystem. Community voice chats do require resources provided by its members though. DEN communities have more granular permission control than Concord/Armada communities.
- Platforms: web, windows, linux
- PWA enabled
- Calling: Voice, Video, Screenshare
- Calling in a community requires Cloudflare Realtime SFU and TURN API keys or a LiveKit server provided by one of the community’s members. Cloudflare SFU/TURN costs $0.05/GB of throughput (with 10 GB/month of free throughput according to DEN’s developer), while LiveKit can be self-hosted or there are some cloud services that provide LiveKit.
- Embedded Content: Images, Videos, GIFs (requires filetype)
- Pro-Features: No Personal Information Required, Open-Source Software, Decentralized, End to End Encrypted
- Anti-Features: Low Metadata Privacy
- If metadata privacy is important, use Armada or another app that
runs on the Concord Protocol. The protocol used by DEN reveals what
communities you’re in as public events on the Nostr network.
- DEN is working on a Hub V2 system that will help to fix this problem.
- If metadata privacy is important, use Armada or another app that
runs on the Concord Protocol. The protocol used by DEN reveals what
communities you’re in as public events on the Nostr network.
- Special Features
- Nostr Network Integration: View general Nostr content from within DEN Chat. Currently supports standard microblog posts and Nostr Reads (long-form blogs).
- Public Topic Chats: Enter a keyword and anyone using the same keyword can read the same chatroom. Messages in these rooms are NOT end-to-end encrypted, however.
- Crypto Wallets: For some reason this app includes both the newer Bitcoin Taproot wallet that’s been appearing in some Nostr clients but also 5 EVM chains (ETH, POL, BNB, AVAX, and Base). You have to sign in using your nsec directly to send from these but you can always view them even when signed-in through a remote bunker or browser signer extension.
Discord
https://discord.com
The big one. The one people love and hate. The one people want to get away from.
- Platforms: web, android, ios, windows, macos, linux
- Calling: Voice, Video, Screenshare
- Embedded Content: Images, Videos, GIFs
- Pro-Features: —
- Anti-Features: Extreme Monetization, Low Regard for Privacy, Proprietary Software
Fluxer
https://fluxer.app
It’s a lot like Discord, but open-source and soon federated. A great choice for people leaving Discord.
Fluxer’s federation support will not be available until
the 2.0 rework.
For spam protection purposes Fluxer may require your phone
number, and they cannot reveal what triggers this as it could be used
against them.
- Platforms: web, windows, macos, linux
- Mobile is in beta; Android is available to all while the iOS beta requires Plutonium.
- Calling: Voice, Video, Screenshare
- Embedded Content: Images, Videos, GIFs
- Pro-Features: Open-Source Software, Self-Hostable
- Anti-Features: May Request Phone Number
- Special Features:
- Discord Template Import: Bring over your entire server’s structure from Discord, including roles and channels.
GroupMe
https://groupme.com
It’s owned by Microsoft. It’s trying to be a Discord alternative. Why does every local group ever use this? Also Copilot.
- Platforms: web, android, ios
- Calling: Voice, Video
- Pro-Features: —
- Anti-Features: Proprietary Software, Low Regard for Privacy, Requires Phone Number
Hyalus
https://hyalus.app
It almost works. I don’t really recommend it.

- Calling: Voice, Video, Screenshare
- Pro-Features: Open-Source Frontend
- Anti-Features: Proprietary Backend
Keybase
https://keybase.io
Cryptographic tools for the masses, including encrypted large-scale chat rooms. A shame it’s closed-source and not well-supported anymore.
- Platforms: android, ios, windows, macos, linux
- Calling: —
- Embedded Content: Images, GIFs
- Pro-Features: End to End Encrypted
- Anti-Features: Proprietary Software

Nerimity
https://nerimity.com
Another great alternative that’s open-source and has all the calling features you want. Also super-customizable and has a social feed on the home page. Sadly bans NSFW content for the people that care.

Nostrord
https://nostrord.com
A community chat platform based on the Nostr NIP29 standard. One downside is that there’s no grouping beyond the relay a room belongs to; to have a segregated space for your rooms you’ll need your own relay.
- Platforms: web
- Calling: —
- Embedded Content: Images, Videos, GIFs (requires filetype in URL)
- Pro-Features: No Personal Information Required, Open-Source Software, Decentralized
- Anti-Features: —
Root
https://rootapp.com
I am no longer in a state of not recommending this app; Root’s
creator has spoken to the community in a YouTube video.
I will still list “Proprietary Software” as an anti-feature as I believe
that the ultimate trust can only be given to open-source software.
See their YouTube video: https://www.youtube.com/watch?v=teVLql3gVpE

- Calling: Voice, Video, Screenshare
- Embedded Content: Images, GIFs (requires filetype in URL)

- Calling: Voice
- Embedded Content: Images, Videos, GIFs
- Pro-Features: Open-Source Software
- Anti-Features: —

Convos Messenger
https://convos.org
A text chat app designed around optionally ephemeral invite-only groups with a new identity for each group you join. Runs on the decentralized XMTP network.
Convos has recently transitioned from a simplistic group
chat app to an app that seems to combine group chats with AI
agents.
You can still create groups (with the compose button in the top right of
the main menu) and chat without participating in AI
usage.

Fernweh
https://fernweh.chat
A chat app based on the Offline Protocol. End-to-end encrypted (with Signal-style MLS tech), and an offline mesh mode when no internet is available. Sadly not anonymous (it requires an email or phone), and while the app itself is not open-source the Offline Protocol is.
- Platforms: ios, android
- Calling: Voice, Video
- Pro-Features: Open-Source Protocol, End to End Encrypted, Decentralized
- Anti-Feautres: Proprietary Frontend
- Special Features:

- Platforms: ios
- Calling: —
- Pro-Features: No Personal Information Required, End to End Encrypted, Spam-Resistant

Signal

The Graveyard
Kloak
https://kloak.app
This app went through many phases. The first phase was the most promising, then it just kept getting worse. The app got hacked once, there were allegations of vibecoding to attempt to erode the app’s reputation, it was stuck in alpha. That was an interesting ride. Armada does Kloak’s job much better though.
