Linux lacks a good key remapping solution. In order to achieve satisfactory results a medley of tools need to be employed (e.g xcape, xmodmap) with the end result often being tethered to a specified environment (X11).

Analysis of keyd

Overall verdict

  • keyd is a highly regarded, open-source key remapping daemon for Linux that operates at a low level to provide fast, reliable, and application-agnostic keyboard customization. It is considered excellent for users needing powerful, system-wide key remapping without relying on desktop environment or X11-specific tools.

Why this product is good

  • Works at the kernel/evdev level, so remappings apply system-wide across X11, Wayland, and the console
  • Supports advanced features like layers, dual-function keys (tap vs hold), and QMK-style configuration
  • Lightweight, fast, and has minimal latency since it operates as a low-level daemon
  • Simple, human-readable configuration files that are easy to manage and share
  • Free and open-source with an active community and responsive maintainers
  • Independent of display server, making it a robust solution for Wayland users where many remapping tools fall short

Recommended for

  • Linux power users who want deep, system-wide keyboard customization
  • Wayland users who need remapping tools that work outside of X11
  • People who want QMK-like functionality (layers, dual-role keys) without custom firmware
  • Developers and vim/emacs enthusiasts who rely on heavily customized key bindings
  • Users of laptops or standard keyboards wanting to remap keys without hardware-level programming

Analysis of Supermemory

Overall verdict

  • Supermemory is a solid tool for building a personal or organizational knowledge base, offering an effective way to save, organize, and retrieve information from across the web using AI-powered search and recall.

Why this product is good

  • AI-powered semantic search lets you retrieve saved content by meaning rather than exact keywords
  • Easily capture bookmarks, articles, tweets, notes, and other web content into a unified knowledge hub
  • Acts as a 'second brain' that helps you connect and rediscover previously saved information
  • Offers integrations and a browser extension for frictionless capture of content
  • Useful for chatting with your own saved knowledge base via an AI interface

Recommended for

  • Researchers and students who collect and reference large amounts of information
  • Content creators and writers who need to organize inspiration and source material
  • Knowledge workers wanting a personal 'second brain' for productivity
  • Developers building AI apps that need a memory or knowledge layer
  • Anyone who bookmarks heavily and struggles to find saved content later

  • I Thought I Wanted System-Wide Vim. I Actually Wanted Arrow Keys on the Home Row
    If all you want is the navigation layer, I recommend keyd. Its configuration is dead simple to read, understand, and edit:. - Source: dev.to / about 2 months ago

  • Why TUIs Are Back
    I remap Caps Lock to Ctrl when held and to Esc when pressed - the best of both worlds. https://github.com/rvaiya/keyd works really well for me on Linux, but there is a similar software on MacOS. - Source: Hacker News / 4 months ago
  • Separating the Wayland Compositor and Window Manager
    Lots of weird misinformation in the comments here. Wayland doesn't choose anything. It leaves the compositor to decide where to position a window and whether or not that window receives key presses or not. The program can't draw wherever it wants or receive system wide keystrokes or on behalf of another program. When appropriately implemented the screenshot system is built directly into the compositor. It's an API... - Source: Hacker News / 6 months ago
  • Ask HN: Where to Begin with "Modern" Emacs?
    > as far as I can tell, no operating system does this in a way that really works besides OSX AFAIK this is an easy setting in desktop environments such as Cosmic, Gnome, and KDE. But I've been using keyd on Linux distros for a while: https://github.com/rvaiya/keyd#quickstart Using the config in the above example results in Caps Lock acting as Esc if used on its own or as Ctrl if it's held down. - Source: Hacker News / 10 months ago

  • AI Agentic Memory for beginners.
    This is usually a challenge that any developer has to take care of when building an AI agent. In fact, managing the context is one of the hardest problems when working with AI agents and there are many companies like SuperMemory, Mem0 which have invested both resources and time to solve this problem. - Source: dev.to / about 2 months ago
  • Building an autonomous Slack agent with OpenCode
    Memory. I use Supermemory for this. Before, Pipa loaded context files and knew to update them. A memory tool adds teammate-like recall: goals, preferences, latest business state, and small details that should carry across runs. Good memory tools also know how to supersede and delete memories, which matters once the agent has more autonomy. - Source: dev.to / 3 months ago
  • Build a Real-Time Voice RAG Agent for Your Documentation
    We wire everything up with Vision Agents as the voice agent framework, Stream for WebRTC audio and video, OpenAI Realtime for speech in and speech out, Anam so the agent shows up as a face on the video, and Supermemory so answers come from search over your uploaded documents instead of guesswork. The code stays small and most of the behavior lives in one registered function that asks the memory store for relevant... - Source: dev.to / 4 months ago
