Nostr

1 Trajectory

Despite early buzz when Will Casarin launched Damus and Jack Dorsey hyped it on Twitter, overall use has plateaued. By late 2025 the data show the number of people posting to Nostr had flatlined or even declined despite slicker apps.

Possibly this is because most people don’t care about censorship resistance or confidentiality. The protocol is still evolving and there are hard core fans, but I wonder how much traction it can gain because established platforms have a stranglehold on attention.

A 2025 review found roughly 21,000 total users and 3,700 daily active users. That’s serious growth from its 2021 origins, but tiny next to Mastodon, Bluesky, or even a mid‑sized Discord. The same report noted a huge increase in profiles with Lightning Network addresses, reflecting Nostr’s close ties to Bitcoin and micropayments. This would, in theory, feed into content creation. Indeed, long‑form posts and articles jumped by 800%.

It’s not massive though, is it? We are probably witnessing the classic cold start problem (a.k.a. the no-network effect): creators go where the audiences are, and audiences go where creators are. Copy‑pasting our posts to yet another microblogging app is a chore with little return. Additionally, the fear of being censored has waned since 2020; most people have moved on and simply don’t see the point. If censorship resistance isn’t a killer app, what is?

2 Implementations

There is no single “killer app” for Nostr. Developers are still experimenting with the look and feel of their clients, and user interfaces range from bare‑bones feeds to Instagram‑style photo apps. Clients like Primal (Twitter‑like), Olas (Instagram‑like) and Yakihonne (Substack‑style) are all exploring different approaches. None of these apps feel fully polished yet.

Early adopters often run several clients because each has strengths and weaknesses. Some apps favour mobile convenience, others focus on desktop or web, and most still require users to manage their own keys and relay lists.

But the overall feel remains that Nostr clients are for tinkerers and enthusiasts rather than mainstream users. If you’re willing to experiment, you can piece together a workable experience; if you expect something as smooth as Instagram or Twitter, you will be disappointed.

Below are some of the more polished options with links and what they offer:

• Amethyst – amethyst.social (Android). An open‑source Android app that hides most of Nostr’s complexity. It automatically discovers and connects to appropriate relays so you don’t have to manage a relay list, can handle hundreds of connections, and routes traffic through Tor by default. Good for: Android users who want a low‑friction way to post and follow without fiddling with settings.

• Coracle – coracle.social (Web). A browser‑based client designed for desktop use. It lets you choose which relays receive each post and supports relay membership lists, making it handy for managing closed groups and forums.

• Damus / Notedeck – damus.io (iOS, Android, Mac/Linux/Windows). It integrates Lightning so you can tip (“zap”) posts and follows. Notedeck is a desktop client with multi‑column views and a fast local database.

• Primal – primal.net (Web, iOS, Android). Primal emphasises discovery: it offers rich feeds, long‑form posts, a feed marketplace and an integrated wallet. You can browse by interest, explore trending zaps and manage your Lightning wallet all from one app.

• Nostur – nostur.com (iOS/macOS). A native client for Apple devices. It supports posting from multiple accounts, guest mode, media uploads, custom lists, and offline storage. Lightning “zaps” and wallet selection are built in nostur.com.

• YakiHonne – yakihonne.com (Web, iOS, Android). Tailored for long‑form content and blogging. Interface includes article‑editing tools and multi‑relay publishing. It also does the integrated Lightning zaps thing. Seems to be targeting the Substack niche.

• Snort – snort.social (Web). A React‑based web client that focuses on speed and usability.

• Hamstr – hamster.to (Web). A simple, Twitter‑style web client that emphasises uncensored speech.

All of these clients AFAICT support the core Nostr functions of posting and reading, but each prioritizes different aspects.
