Pulsar

Pulsar is a hyper-hackable text editor forked from Atom and built on Electron. It continues the Atom project after its sunset, keeping the editor open and deeply customizable while staying approachable with its default configuration.

The editor is designed to be reshaped to fit your workflow, letting you adapt its interface and behavior down to fine details. As an Electron app, it runs as a familiar desktop editor on Windows, macOS, and Linux.

Pulsar is developed as Pulsar Edit by a community of contributors rather than a single vendor. It is a self-hosted, MIT-licensed editor you install and run locally, not a hosted service.
