Textcaster is now RSC — Really Simple Conversations

Same project, new name and new home.

RSC stands for Really Simple Conversations — a nod to the acronym that started all of this. It also says what the project actually does that a feed reader doesn't: posts, replies, and whole conversations travel as RSS, so following, threading, and federation work with nothing but open feeds.

New homes:

• rsc.rmdes.be — this instance
• alice.rmdes.be and bob.rmdes.be — the two federation peers
• the source code

Every old textcaster.app link still works (for a year) until the domain die.

The old domains now issue permanent, path-preserving redirects to their counterparts, so existing permalinks, feed URLs, and any conversation already federated out there keep resolving. Posts published before the move keep their original GUIDs on purpose — remote instances and readers won't see a flood of duplicates, and threads stay intact.

If you subscribe to a feed here, you don't need to do anything: the redirects are 301s, so well-behaved readers will quietly update their subscriptions to the new address.

One small thing if you have an account: you'll be signed out once. Session cookies are namespaced to the app name, so the rename invalidated them. Log back in and you're set.

Your personal feed reader is open — subscribe & manage is live

The per-user feeds milestone is complete. SP1 built the engine, SP2 gave you the four tabs — and now the part you actually touch is here: subscribing to feeds and managing who you follow, fully self-serve. No admin required.

Subscribe, right from home

There's a subscribe form on the home page now:

1. Paste any feed URL — https://their-site.com/feed.xml
2. Say what it is: a site or publication, or an individual
3. Hit Subscribe

Where you land depends on what you subscribed to:

It's rate-capped and SSRF-checked — you can't blow past the per-user limit or point it at internal addresses. And like everything here, the form is a plain post: it works without JavaScript.

Manage who you follow

Your following page is now a real manager:

• Your own /u/<you>/following → "Your subscriptions," each row with an Unfollow button, plus a "Follow someone" box.
• Anyone else's → a read-only list of who they follow, with Follow buttons that act as you.

Personal river looking empty? Home nudges you: "follow people and feeds to fill it."

For admins

A new Settings tab under /admin exposes Max subscriptions per user — tune the per-user cap live, no config edit.

So that's the whole loop: subscribe → read your Personal river → manage → done. Textcaster is a feed reader with a social layer now, end to end. 📡

🔜 Coming next: subscribe & manage (SP3)

The engine is live but the web still needs to catch up. Next up:

• A self-serve subscribe form on home — paste a feed URL, pick person or web feed, done. (No more admin-only "add" button 403-ing everyone.)
• A real following manager — your own following page becomes full follow / unfollow / manage; other people's stays read-only.
• An admin Settings tab for the subscription cap.
• Plus fixes riding along: feeds stop showing as raw URLs, pasting your own instance URL resolves cleanly instead of shadow-subscribing, and tighter follow guards.

Today you can already browse all four tabs and read your Federated/Public rivers. Soon you'll wire up your Personal river with a couple of clicks.

Per-user feeds (SP1 / SP2 shipped, SP3 next)

Textcaster is becoming a feed reader — with a social layer

Until now Textcaster had one timeline: the instance firehose. We're rolling out per-user feeds in three parts — the first two are live right now.

✅ Shipped: the subscription engine (SP1)

Every registered user can self-serve their own subscriptions. Feeds carry a type:

• person and webfeed → anyone can subscribe (registered, rate-capped, SSRF-checked).
• instance → admin-only. These are the federated peers (the Connected instances), shown to everyone.

Under the hood: a capped POST /me/subscriptions, follow/unfollow with orphan cleanup, OPML import and export, and an admin-configurable subscription cap.

✅ Shipped: the four-tab home timeline (SP2)

Home is now tabbed — four lenses over the same live pool, each with real-time prepends and each a plain ?tab= link (no-JS friendly):

Signed in, you land on Personal by default. Guests land on Public. Your profile at /u/<you> is where "just me" lives — it isn't a tab.

Shiped today Multi-session

Two accounts, one browser, zero re-logins

Textcaster now supports multi-session: keep several accounts signed in on the same browser and switch between them instantly — no logging out, no re-typing passwords.

Handy if you run a personal account and a project or bot account, or you're just testing how the timeline looks as someone else.

How to use it

1. Sign in to your first account as usual.
2. Open your Accounts page (/accounts, linked from settings).
3. Hit Add account and sign in to the second one — both are now held on this browser.
4. Back on Accounts, click Switch next to any account to become it. That's it.

On the Accounts page you get

• A current badge on whoever you're posting as right now.
• Switch — one click to jump to another held account.
• Log out — sign out of just that account, staying on the others.
• Log out of all accounts — clear the whole set.

You can keep up to 3 accounts signed in per browser. It's registered-only — guests don't see the switcher.

Everything is server-driven and works without JavaScript — the switch is a plain form post, same as the rest of Textcaster.

must be why my cat is grey then :)

New today: you can edit your own posts now.

The interesting part isn't the edit button — it's that posts here are RSS, so an edit stays current everywhere it's travelled. Change a post and it carries an atom:updated marker on its stable permalink; every instance that already pulled it in notices on its next poll or push, updates its copy, and keeps its own revision history. No silent overwrite — and it doesn't jump your post to the top of the timeline.

We tested it live today: edited a post right here, then watched it propagate to two other instances, each independently recording the previous version. Posts that stay current, wherever they've been.

feel free to change your handle in the setting page !

Hello back at you :)

One thing that bugs me about reading a firehose: you meet someone great through an aggregator, and then every future post by them stays trapped inside that aggregator's stream — tagged with their name but owned by the river. But the firehose already tells us where they really live: every item carries a <source> pointing at the author's own feed. We ingest it, we store it, we even show it as a little feed icon. So why not let you click it and actually follow the source? One tap turns "someone I saw go by" into a first-class feed on your timeline — threaded, pushed, attributed to them, no aggregator in the middle. It feels like the most Textcasting thing possible: the wire already knows the way home, we just have to open the door. Would you want it to also quietly hide the duplicate still coming through the firehose, or keep both and trust you to unfollow the river yourself?

there is a bug here, rss.chat should display as link

Quick tour of the composer 🎉

Type / for the slash menu, : for emoji autocomplete, and toggle Write / Preview to see the render live. Bare links autolink → https://textcaster.app

Single newlines are line breaks —
like a chat,
not classic Markdown.

What ships today, and what's someday next:

• ✅ Live SSE timeline — works with JavaScript off
• ✅ Markdown composer with live preview
• ✅ Conversations that federate A→B→A over plain RSS
• 🚧 IndieAuth + Micropub — coming next

"Subscribe to feeds, /inReplyTo threads them." — the whole model in one line.

Built on Textcasting.

One post, many contracts — the same content reaches every kind of reader:

📰

Threading over plain RSS is just matching a reply's reference to its parent:

function resolveReply(item: FeedItem, posts: Post[]): Post | null {
  const ref = item.inReplyTo ?? item.thrInReplyTo
  return posts.find(p => p.url === ref || p.guid === ref) ?? null
}

No cross-server API. No shared database. Just feeds. 🚀
