Netchat

Netchat

Serverless LAN messenger

Description

Sending a file to the person two desks away shouldn't mean bouncing it through a cloud service — and on an isolated intranet there may be no internet at all. Netchat just works: it discovers other users on the same subnet automatically, with no server, no sign-up, and no message ever leaving the local network.

The whole thing is a 2 MB executable you unzip and run. It sits next to the taskbar clock, and one click lets you chat, send your clipboard or drop a file on someone. Handy for offices, labs, offline intranets and LAN parties.

Features



Automatic discovery: Anyone running Netchat on the subnet shows up in the list with machine name and IP — no contacts to add.

Broadcast and channels: Send one message to everyone on the network, or set up channels for a smaller group.

Read receipts: On by default, so you know whether a message was actually seen.

Offline messages: When someone is offline, the message can be parked on an FTP server and delivered once they come back.

Files and clipboard: Send files, links or clipboard contents directly; a built-in HTTP server can also share pictures and other files.

Bridge subnets: Add a fixed user on another subnet to act as a gateway and join two Netchat networks together.
