Substr Update - Shared Nostr Events, Community Space Cards, Live Stream Polish
Quick build update from Substr. I’ve shipped a lot of product polish recently, but two bigger areas deserve a deeper explanation: Shared Nostr Events and community-level customization.
**Shared Nostr Event posts **
Substr is community-scoped by design. I intentionally do not load the full global Nostr firehose into every /s/.
That keeps communities focused, but it also creates a practical issue: people often want to bring an existing Nostr post into a community thread.
So I added Share Nostr Event posting.
What this does:
- You can post a Nostr event reference directly into a substr.
- The shared card resolves richer content (mentions, links, media, video) instead of just showing raw IDs/URLs.
- Engagement actions (likes, zaps, replies) are wired toward the original event target, so interaction stays meaningful across clients.
- I improved repost compatibility so shared behavior is clearer outside Substr too.
Why I did it this way:
- In a global client, “repost” can assume broad feed context.
- In a community-scoped client, I need a wrapper that anchors the post inside a specific space while still respecting the original event.
- This is my bridge between “community context” and “cross-client interoperability.”
**Community space cards (making each /s/ more ownable)
**
I also expanded moderator controls for the right-side “space” layer with dedicated cards:
- Message card (editable title/body)
- Social links card (compact icon-first links)
- Useful links card (curated title + URL entries)
This gives each community a stronger identity without turning setup into a heavy CMS flow.
I’m exploring how to make communities even more distinct and self-owned:
- stronger space identity patterns,
- clearer utility cards,
- better “what this community is for” signaling,
- and more creator/show/community-specific layouts over time.
Other smaller fixes
- Relay UX refinement: compact cards, status dots, clearer relay info.
- Signer/login flow cleanup with better QR/copy/manual paths.
- Mobile-first signer onboarding improvements (wizard flow, clearer steps).
- /s/ sharing improved for PWA (native share first, copy fallback).
- Atmospheric background behavior fixed (viewport-anchored, no stretch on long pages).
- Rich-text mention parsing improved (nostr:nprofile... support, including leading emoji cases).
- Clickable identity and /s/... badges expanded across more surfaces.
- Stream + chat improvements: better layout, publishing/read behavior, diagnostics, and interaction polish.
Cheers and on to the next one!

We just shipped the first step towards livestreams on Substr.network
Moderators can now add a live stream
by pasting a Nostr naddr.
Stream + chat, directly inside the Substr.
the foundation is there, but should build further on feedback.

From brainfart to execution. We’re almost there... 😄
Soon all you’ll need to do is paste your NADDR and your stream will be visible on Substr, including chat. Just needs some little tweaks and polish.

You can manage your own relays in Substr.network. just head over to settings, relays and add the relays you want, same for DM 's

still building. still learning.
Login Signer Flow Update
Spent some time tightening up the signer flow in Substr.
We cleaned up the connect modal, made the remote signer option easier to understand, and added a few fallback paths for mobile when opening a signer app doesn’t work right away.
You can now connect through the app directly, use a QR code, copy a Nostr Connect link, or fall back to a manual bunker setup.

Todays theme is Brutalism 😎
Video upload ✅ Livestream next?
Added video upload support on substr.network. Makes me think, Content creators can already run their own Substr.
Should we take it one step further and add livestreaming? Imagine going live inside your own Substr community —
chat, comments, zaps… all in one place

Should we add another post type? If so, which one? 
Add mentions or keep it clean?
I’m considering adding an @mention feature in posts and comments/replies.
Not sure yet if it improves interaction or just adds noise. Curious how others feel about it.

Substr, For more logical feeds 
Goal for the coming days!
The goal in the coming days is to improve media uploads on Substr.
Right now we’re using nostr.build with NIP-98, which works well as a starting point.
Next step is moving towards a Blossom-based setup.

Unexpected Substr Update - NSFW controls fase 1
Wanted to share another Substr update after a new round of improvements and cleanup.
Here’s what changed recently:
- Added the first NSFW controls to Substr.
- Posts can now be marked as NSFW during creation.
- Communities can block NSFW posts through their content policy.
- Users can now choose to hide NSFW posts in their own Substr settings.
- Instead of removing those posts completely, Substr now keeps the card visible and shows a simple blocked state with a link back to settings.
- Added a separate setting to blur all media previews by default, even outside NSFW.
- Media previews can now be revealed manually with a single click when that setting is enabled.
- Improved the post text expand/collapse UX with a more compact inline button on cards.
- Fixed pinned posts showing up in the personal joined feed where they did not belong.
- Improved theme customizer behavior so a manually chosen radius no longer resets when switching between light and dark mode.
- Cleaned up some favicon and sitemap setup so search engines get a clearer picture of more indexable pages like Explore and About.
If anyone has more ideas, feedback, or things that feel off, always happy to hear it.
Cheers
