Hey HN! I’ve written a bunch of WebSocket servers over the years to do simple things like state synchronization, WebRTC signaling, and notifying a client when a backend job was run. I realized that if I had a simple way to create a private, temporary, mini-redis that the client could talk to directly, it would save a lot of time. So we created DriftDB. In addition to the open source server that you can run yourself, we also provide https://jamsocket.live where you can use an instance we host on Cloudflare’s edge (~13ms round trip latency from my home in NY). You may have seen my…

I built LocalGPT over 4 nights as a Rust reimagining of the OpenClaw assistant pattern (markdown-based persistent memory, autonomous heartbeat tasks, skills system). It compiles to a single ~27MB binary — no Node.js, Docker, or Python required. Key features: - Persistent memory via markdown files (MEMORY, HEARTBEAT, SOUL markdown files) — compatible with OpenClaw's format - Full-text search (SQLite FTS5) + semantic search (local embeddings, no API key needed) - Autonomous heartbeat runner that checks tasks on a configurable interval - CLI + web interface + desktop GUI - Multi-provider:…

Hi HN, I’ve wanted a simple solution to handle Wake-on-LAN sequences for my home and work labs to boot up servers in the right order. I was already dabbling in Rust and thought this would be an interesting project to dive deeper and see if it could work well for this kind of network tool. The result is rallyup. rallyup lets you set up server dependencies in a YAML file, so each service (e.g., firewalls, storage, VM hosts) comes online in the right order. It verifies each server’s status before moving to the next. Features: - Dependency-based WOL with VLAN support - Built-in health checks…

I've frequently found myself using [nvitop](https://github.com/XuehaiPan/nvitop) to diagnose GPU/CPU contention issues. The two best things about it are: - It's easy to install if I can access pip in the container - It makes a compelling screenshot (which helps me communicate with coworkers.) With those two lessons in mind: Here is Sping! Purpose: Help observe and diagnose latency issues at layer 4+ (TCP/HTTP/HTTPS) Two good things about it: - It's easy to install if you have pip. (Available at…

Hey folks! Shahar and Tal from Keep (https://www.keephq.dev) here! For the last few weeks we’ve been building Peeng and can now share our beta with you: https://www.peeng.sh. Peeng is the easiest and quickest “heartbeat” architecture we could think of. Just pick a subdomain (e.g. x.peeng.sh), configure an interval, an endpoint, and a payload, and hit that subdomain every <X (interval) seconds — If you won’t, Peeng will send an HTTP POST request to your configured endpoint. It’s Pingdom/Cronitor/heartbeat.sh free alternative (but the other way around and A LOT…

Hey HN, I'm the maintainer of node-cron (5M+ downloads/month), and I recently built Sidequest.js, a background job runner for Node.js inspired by Oban (Elixir) and Sidekiq (Rails). It solves some common problems I saw with libraries like node-cron: - Jobs don’t block your API: they run in isolated worker threads - No Redis or vendor lock-in: use Postgres, MySQL, SQLite, or MongoDB - Supports retries, uniqueness, concurrency, snoozing, prioritization - Comes with a CLI and a simple dashboard - Works great in monoliths and doesn’t require extra infra Quick start (no signup needed):…

Hi HN, I'm one of the founders of s2.dev. RePlaya (https://github.com/s2-streamstore/replaya) is a self-hosted browser session replay tool using rrweb (https://github.com/rrweb-io/rrweb). It occurred to me that a durable stream per session would be a much neater architectural foundation for much of what you'd want from such a tool. As a unique feature, it also made live tailing straightforward because the player can read from the same stream the recorder is appending to. The alternative architecture is likely an ingest firehose which is then indexed,…

I built a tool that stores your full Claude Code history to let you easily find and resume sessions. It has TUI, CLI and MCP interfaces. It's a single Go binary, and the session history is synced to SQLite each time you use it. Default mode is the TUI with a session browser and full-text search. Once a session is selected you can browse and search within it, resume it or export to markdown. The MCP server provides tools to let Claude search back through the session for pre-compact context or pull from prior sessions. I use this constantly. I've seen elaborate continuity systems to give…

I kept seeing every npm/pnpm/yarn/bun/uv supply chain post end with the same advice (set a minimum release age, turn off install scripts), and while I know cooldowns are "controversial", they do work. But even if you convince people that they should set cooldowns, it seems many don't end up following through, not sure why, maybe because it means hand-editing five config files in five formats with five different time units, or perhaps the "it won't happen to me" syndrome (or "I'll do it later, it seems complicated" where it's actually very simple). So I created a tool that…

Hi HN, Some misbehaving networks drop WireGuard packets either by accident or on purpose. Commonly the latter is done with simple DPI rules that block the handshake initiation [1], but it could be applied to other message types as well. We thought it would be great if there was tool for folks to use as a quick litmus test to see if this happening for them, without having to configure a client to send data through a random, functional WireGuard tunnel to an untrusted remote host. So we built probe.sh. How it works: - The probe.sh web app is an Elixir Phoenix app that spawns a few gen_udp…

unsock is an LD_PRELOAD-able Linux library that converts AF_INET socket connections to AF_UNIX, AF_VSOCK, AF_TIPC, etc, helping reduce the dependency on TCP/UDP/IP for local communication. It even handles the painful "CONNECT" proxy dance on Firecracker AF_UNIX/AF_VSOCK multiplexing sockets for you.
