Linux memory pressure evaluation discovery toolkit
Show memory pressure in menu bar on macOS
Swift iOS library for adaptive feature gating based on device performance, Low Power Mode, thermal state, memory, and storage.
tool to eat ram. *nom-nom-nom*
CPU and memory in the Mac menu bar, with memory read the way macOS reads it: by pressure, not free pages. Native, no dependencies, built from source.
Inspect macOS process ownership and resource history in a compact popup, then choose whether to stop a process.
A script to allow memory pressure information from newer Linux kernels to be displayed as sensors in KDE's KSysGuard.
Pauses idle background apps on a Mac under memory pressure and resumes each one when you switch back. Every pause is journaled and undone after a crash; starts in Observe mode; never deletes files. Validated on one Mac (see Validated scope in the README). Formerly iClean.
Off-heap Go memory allocator with lock-free slab allocation, generation-safe Reset, and huge page support. Zero heap pressure.
Monitor CPU, memory, GPU, and network performance with this native macOS tool that records system metrics locally for detailed process diagnostics.
Free macOS menu bar app that stops your Mac from crashing/restarting when it runs out of memory: force-closes iOS Simulators (and Android emulator) when RAM gets low. Xcode, kernel panic, memory pressure.
Android RAM stress-test tool. Allocates memory via native mmap inside a foreground service to study low-memory behavior and the OOM killer.
macOS app that shows a memory pressure indicator in your menu bar.
Thin benchmark harness for local LLM endpoints — TTFT/prefill/decode with distribution, correlated with macOS memory pressure and thermal throttling. Same code on M1 (LM Studio) and M5 (mlx-lm), just swap the config.
Tiny TUI that watches what terminal coding agents spawn and kills orphaned workers before memory pressure drowns your machine
See what is slowing down your Mac: a local dashboard for RAM, swap, CPU and disk that groups hundreds of processes into the apps you know and tells you what to close.
Menu bar early-warning system for macOS watchdog kernel panics — live pressure/swap/disk monitoring with a pre-crash flight recorder
Linux system strain indicator that outputs a single score from 0 to 100+. Provides better actual system utilization compared to load-average.
Step-level simulation of chunked prefill under KV cache pressure. Block policy wastes 89.6% of prefill chunks while achieving the same throughput as upfront rejection. Chunk waste rate is the metric standard throughput metrics miss.
