local only

CoreTend runs on your own machine — the client starts it, so there is no endpoint to ping. 58 installs a week from npm. Last commit 17 Oct 2026.

Read-only view of what fills a Mac: disk usage, cleanup candidates, largest items, app leftovers.

What the code does

We read the source, 2 d ago · rules 995398eba69f

In the project's build, not in the package

Found in continuous integration, deployment or infrastructure files, or in a neighbouring package of the same monorepo. None of this is installed when you add the server: it describes how the project is built and released. We list it because a leaked key in a build pipeline is still a real problem, but it is not something this server does on your machine.

Claims read-only, but the code runs commands Sources/CoreTendHelper/Launchctl.swift:15
        let process = Process()
Installs itself into autostart Sources/Domain/AppLeftovers.swift:40
            ("LaunchAgents/\(id).plist", .identifier), ("Application Scripts/\(id)", .identifier),
Builds a database query by concatenation Sources/DesignSystem/ScanRoots.swift:56
            let drop = rect.height * 0.16 * grown
            let end = CGPoint(x: origin.x + branch.side * reach, y: origin.y + drop)
        let process = Process()

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

Nothing serious here today

Today is the operative word: we check CoreTend every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

CoreTend — questions

Answers built from our own checks of this server.

Why is there no uptime for CoreTend?
CoreTend runs on your own machine over stdio — there is no network address to reach, so uptime cannot be measured for it by anyone. What can be measured is adoption: the npm package coretend was installed 58 times last week.
How do I connect CoreTend?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It runs locally, so the command pulls coretend straight from npm; nothing to host, nothing to sign up for.
How many people use CoreTend?
The npm package coretend was installed 58 times in the last week. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is CoreTend open source?
Yes — it is published under the Apache-2.0 licence, written in Swift and 1 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
