Pulsar

Pulsar Edit is a free, open-source, community-driven code editor built as a continuation of the legendary Atom editor. After Atom was discontinued, developers created Pulsar to keep the “hackable editor” philosophy alive while modernizing it for today’s workflows.

It is designed to be lightweight, customizable, and developer-friendly, making it a strong alternative to VS Code for users who value flexibility and open architecture.

🚀 What is Pulsar Edit?

Pulsar is a fork of Atom, rebuilt and maintained by the community. Its main goal is to preserve Atom’s strengths while improving performance, stability, and modern development support.

It runs on Electron and supports a wide ecosystem of plugins and themes, making it highly customizable for developers of all levels
