Deep in AI-assisted coding, you lose track of how many local servers are up or where your RAM went — until the Mac stutters and something dies mid-flow, usually on top of unsaved work. That frustration is why I built this — just what matters, always in the menu bar.
Click the % in your menu bar to open this panel
Dozens of browser tabs, plus Docker and simulators — 16 GB fills up fast. macOS quietly spills memory to disk (swap), and at some point everything stutters and apps get force-quit. Usually right on top of unsaved work.
Memora keeps that signal in your menu bar at all times. It shows usage and pressure as color, and when swap spikes or pressure turns red, it warns you first — before you lose your work.
A single window that opens from the menu bar — with only the metrics developers actually care about.
CPU, memory, disk, temperature and battery as rings that change color with load. Click one to expand the detail.
Every running dev server with its runtime (Next.js, Vite, Node) and uptime. Open or stop it in one click.
See what's spinning the fan and eating RAM, app by app. Quit it right there.
Shows what DerivedData, node_modules and Docker have swallowed. It never deletes — you decide.
When memory, swap, disk or heat get risky, it alerts you before apps get force-quit.
Korean, English, Japanese, Chinese (Simp./Trad.), Spanish, French, German, Portuguese, Russian. Switch instantly in Settings.
Switch branches a few times and you've got three or four dev servers running. You can't remember which port belongs to which project, and something you thought you killed is still holding a port. Instead of running lsof or digging through terminal tabs —
Memora finds every local server that's currently up. Which framework it is, which folder it's running from, how long it's been alive — all on one line. Click to open it in the browser, or stop it right there when you're done.
macOS is designed to fill spare RAM with cache. The "cleaner" apps that claim to free it just change a number for a moment — and by dumping that cache, they actually make apps slower. Memora is different: it shows accurate figures the same way Activity Monitor does, and tells you before a real problem hits.
A universal binary — no installer, no steps. Just download and drag it to your Applications folder.
macOS is designed to fill spare memory with cache, so forcing it to empty does not help. The number that matters is not free space but memory pressure. While pressure is green, high usage is normal and healthy; only when it turns yellow or red should you quit heavy apps.
Mostly no. Apps that force-purge RAM only make the free-memory number jump for a moment, while throwing away cache macOS was about to reuse — which usually makes things slower again. A tool that shows you the real state is more useful than one that changes a number.
If memory pressure is red or swap keeps growing, you are genuinely short on memory. The most reliable fix is quitting the apps using the most RAM — browser tabs, Docker, simulators. A restart only helps when pressure stays high no matter what you close.
The built-in tool is the Memory tab in Activity Monitor. The catch is that you have to open it every time, so problems are easy to miss. Memora keeps usage, memory pressure and swap in the menu bar at all times and warns you before things get bad.
Memory pressure is the macOS indicator of whether memory is genuinely scarce. Usage can be high while pressure stays low, which is fine. When pressure rises, macOS starts moving memory to disk (swap) and the whole system slows down — making it a far better signal than free space.
Yes, completely free. There are no ads, no in-app purchases, no paid tier and no account required. It runs on macOS 13 Ventura or later on both Apple Silicon and Intel Macs — download it and drag it to your Applications folder.
Usually a dev server you started earlier is still running and holding that port. You can find it with `lsof -i :3000` in the terminal and quit that process. Memora lists every port that is currently open, so you can find the one you want and stop it right there.
The built-in way is `lsof -i -P | grep LISTEN` in the terminal, though it does not tell you which project each server belongs to. Memora shows every open port together with its framework (Next.js, Vite, Node and others), the folder it runs from, and how long it has been up.
If a server binds to 0.0.0.0 instead of 127.0.0.1, other devices on the same Wi-Fi can reach it, which matters on cafe or shared networks. Memora flags servers that are open this way with an exposure warning.
Almost always because one app is holding the CPU. Browser tabs, builds, Docker and video calls are the usual culprits. Finding that app and quitting it brings both the temperature and the fan noise down.
macOS does not show temperature by default, so it takes a separate tool. Memora reads Apple Silicon's built-in sensors and shows the average SoC temperature, the hottest spot and the SSD temperature in the menu bar. Temperature is not available on Intel Macs.
The CPU tab in Activity Monitor shows this. Memora presents the same figures per app in the menu bar and lets you quit the offending app on the spot.
On a developer's Mac, Xcode DerivedData, iOS simulators, Docker images and npm or yarn caches routinely take tens of gigabytes. Checking those first is far more effective than deleting photos or documents.
Usually yes — they are build artefacts that get regenerated when needed. The catch is that regenerating them takes time, so it is worth avoiding right before a deadline. Memora only shows you the sizes and never deletes anything itself.
No. Every measurement happens on your Mac and nothing is sent anywhere, and no account is required. The only data that leaves your machine is a suggestion or rating you choose to send yourself.
When a new version ships, it downloads quietly in the background and applies on your next launch. You can turn automatic updates off in settings, or check for one manually whenever you like.
