LESSRAM

Communication without the overhead.

Less RAM. Less CPU. Less bloat. Just communication.

Talk to your friends while you play, without a chat client taking a chunk of your machine to do it. Friends, direct messages, servers, voice channels and screen sharing. Nothing else.

A LESSRAM server channel: channel list on the left, conversation in the middle, members on the right.
A server channel. Tight rows, quiet colours, nothing competing for attention.

What it does

The things people actually use, built properly, and nothing else.

Servers & channels

Create a server, invite your squad with a code, talk in text and voice channels. Sensible defaults, basic roles.

Friends & direct messages

Add people by username, see who is online, message them or call them directly. No server required.

Voice built for games

Peer-to-peer audio, mute and deafen from a global shortcut, and a call that survives a few seconds of dropped wifi.

Screen sharing

Share a screen or a single window at up to 60 fps. When bandwidth tightens it drops resolution, not frame rate.

A floating widget

A small always-on-top handle that never steals focus. Answer a call without leaving your game.

Out of the way

Close the window and LESSRAM releases it entirely, keeping only the connection, the tray and the widget.

Performance is the feature

Measured on Windows 11 as private working set — the memory the app actually costs, not the inflated figure you get from adding up shared pages across processes.

 Idle is the number that matters, because that is the state LESSRAM is in while you are playing. It is not achieved by hiding the window — the interface is genuinely released a few minutes after you close it.

Connected to voice. Mute, deafen and screen share work while the window is closed.

Requirements

Windows 10 or 11

64-bit. Installs per user, so no administrator rights are needed.

About 250 MB of disk

Plus whatever files you share. Updates download in the background.

A microphone

Any headset. LESSRAM handles one being unplugged mid-call without dropping you.
