Zed

Zed is a high-performance, multiplayer code editor with edit predictions and an agent panel that can use Zed-hosted models, your own API keys, or external agents. The editor is open source (GPL-3.0-or-later, some Apache-2.0 parts), and you decide how much AI to use. Privacy note: client telemetry (usage metrics and crash reports) is on by default and can be turned off in settings.
