Nova

Nova is Panic's Mac editor, and the thing it is really selling is Mac-ness: real native text rendering, window behaviour that matches the rest of the system, a sidebar that works like a Finder sidebar, an integrated terminal that is not a web view impersonating one. It carries the Coda lineage, so it is built around web and front-end work, with remote file sync and SFTP publishing treated as first-class rather than bolted on.

Git is built in with side-by-side diffs, and extensions cover languages, themes and linters — though the library is smaller than the Electron editors', and you will feel that on a less common stack. For large compiled projects, Xcode or a JetBrains IDE does more.

The licence needs reading slowly. $99 buys the app plus one year of updates, then Panic charges $49 a year to keep receiving new versions, and that renewal is automatic. Cancel it and you keep a fully working copy of whatever build you were on, permanently. That is what puts Nova on this site, but it is the least "lifetime" entry here, and standing still on an editor is more expensive than standing still on, say, a launcher.

Use the 30-day trial properly. If the native feel is not worth the money to you inside a month, no extension is going to close the gap later.
