Messaging looks simple until delivery states, unread counts, push notifications and offline queues disagree with each other. I build chat around a clear message lifecycle, so the client, the server and the notification system tell the same story.

Composing, queued, sent, delivered, read and failed are different states, and each one needs a rule for what the user sees. If the app only knows 'sent', a message that never left the device can look successful. I design the lifecycle first, then make the UI and the push notifications follow it.
The same thinking applies to conversations: unread counts, last-message previews, muting, blocking and deletion all need to agree. Those details are what make a chat feel trustworthy even when the connection is poor.
Firebase is often a good fit for a small team that wants managed real-time delivery. A Laravel API with WebSockets gives more control over storage, permissions and business logic. The right choice depends on message volume, retention, admin needs and whether the rest of the product already lives in one of those stacks.
I can build one-to-one and group chat, media messages, presence, typing indicators, read receipts and push notifications. I can also add moderation tools and an admin view so the product is operable after launch.
Phones lose connectivity, change networks and get killed in the background. The app needs a local queue, retry rules and a visible failed state instead of silently dropping a message. Push notifications need to be idempotent, because the same event can arrive by socket and by push.
I test the awkward cases: send while offline, receive while the app is closed, switch from Wi-Fi to mobile data, and open a conversation from a notification. Those are the moments that decide whether users trust the chat.

It depends on volume, retention, admin needs and the rest of your stack. Firebase is often faster to start; a Laravel/WebSocket backend gives more control over data and business rules. I will recommend one after looking at the product rather than defaulting to either.
Yes. I would first review the account model, notification setup and data layer, then add messaging without duplicating identity or creating a second source of truth.
The app keeps a local queue, shows a clear pending or failed state, and retries when connectivity returns. Server-side idempotency prevents the same message being stored twice.
Transport encryption is standard. End-to-end encryption is a much larger product decision with trade-offs for moderation, backups and multi-device support. We would decide explicitly whether you need it rather than implying it by default.
Yes. Report, block, mute, message removal, conversation lookup and an admin queue can be included from the first release.
The API can serve multiple clients, but the interface has to be designed for each one. A TV chat experience is not a phone chat stretched across a screen.
