Custom team chat — real-time, with unlimited history.
We've shipped a real-time team messaging system — direct + group + channels, file attachments, read receipts, presence, edits with audit, guest access. If you need yours without Slack pricing or retention limits, this is what it takes to build.
A production-grade chat module already built and running. We ship a custom one for clients who need their own.
ragenaizer.com / chatWhat goes inside a real chat.
These are the moving parts we've shipped before. Your custom build picks a subset — and we tell you upfront which parts are worth re-implementing and which ones aren't.
Real-time over WebSocket
Persistent connection per client, message fan-out via a pub/sub layer. Reconnect-and-catch-up logic baked in.
Channels, DMs, groups
Public / private channels, multi-party DMs, threaded replies.
Unlimited history
No 90-day deletion. Search across every message you've ever sent.
File attachments
Auto-saved to Drive, with audit trail, with the same access controls.
Edits + deletes with audit
Editable for a window, deletable, both leave audit-log entries.
Presence + receipts
Online / Away / Busy / Offline, read-by receipts per channel.
Guest access
Bring vendors / clients into a single channel without expanding their reach.
Video escalation
Any chat → instant video call via Vision. No tool-switching.
The problems that don't show up in the demo.
These are the ones that take a custom build from "works in a screenshot" to "works in production for three years." We've already learned them once.
- 01 Fan-out at scale — a single message in a 10K-member channel needs to reach every connected client in <200ms.
- 02 Message ordering — multiple senders, multiple servers, monotonic ordering with conflict resolution.
- 03 Search that handles emoji, code blocks, and 17 languages without tokenisation drama.
- 04 Mobile push that arrives before the client opens the app, without draining batteries.
- 05 GDPR / DPDP delete — a user requests deletion, every reference of theirs needs to actually go.
How we'd put it together.
ASP.NET Core + SignalR for WebSocket transport, Postgres for durable storage, Redis Pub/Sub for fan-out, MeiliSearch for full-text. Push via FCM / APNs.
We'll tell you when not to build.
Custom isn't always the right call. We've shipped Ragenaizer so we can say that honestly.
- →The chat is the moat — your competitor can't have the same one.
- →You have compliance / sovereignty / data-residency requirements no SaaS will satisfy.
- →You need to integrate at a level deeper than off-the-shelf vendors expose.
- →Per-seat pricing across thousands of users makes the build cheaper inside 24 months.
- →The workflow is generic enough that a configurable platform will do.
- →You want it in weeks, not quarters.
- →You'd rather buy than own — let someone else maintain the chat forever.
- →Your engineering capacity should go to the parts of your product that no SaaS covers.

One conversation. We tell you whether it's a custom build, a Ragenaizer rollout, or something we shouldn't take on.
