Show HN: NodeDB – High Perfomance Multi-Model Database https://bit.ly/4d5meMY

Show HN: NodeDB – High Perfomance Multi-Model Database Hey HN, I've been working on a multi-model database called NodeDB. Originally, i've found out the idea of SurrealDB quite good. However, it doesn't have some graph and vector features that I need. And since it is just a KV wrapper, instead of purpose-built engine, the performance will never be close to the specialized databases (like Neo4j, Pinecone, Clickhouse, etc). And i've asked myself, what if, there is a database that have the same idea, but built differently? Instead of just treating it as KV database, we build specialized engines for the data. Besides that, I want it to be able to support my IOT/edge project, where i need offline sync capabilities (Currentyl still in progress). Will it work? I put it into test. I've been experimenting and researching for a year, creating multiple versions, and then I created NodeDB. Disclaimer: It is still in public beta (as of May 2026), but it really excites me if I can make this db work. And I use AI as assistant for coding and planning. It is nearly impossible to do as a solo developer without any AI assistance. Would love feedback from HN: - Are there specific features or improvements that would make it more useful? If you're interested in experimenting or contributing, the repo is here: GitHub Repo: https://bit.ly/4nlpE1s Looking forward to your thoughts! https://bit.ly/4nlpE1s May 12, 2026 at 12:21AM

Show HN: Safe-install – safer NPM installs with trusted build dependencies https://bit.ly/4nnPzW8

Show HN: Safe-install – safer NPM installs with trusted build dependencies In light of the ongoing npm supply chain compromises, I built safe-install: https://bit.ly/4wpkUvV It brings a couple of protections I wanted from npm but are not built in. Similar to Bun’s trusted dependencies, it lets you disable install scripts by default and define a list of dependencies that are allowed to run build/install scripts: https://bit.ly/4nr62sS It also supports blocking exotic sub-dependencies, similar to pnpm’s `blockExoticSubdeps` setting: https://bit.ly/4wGyKub... I was hoping npm would eventually add something like this, but it does not seem to be happening soon, so I made a small package for it. https://bit.ly/4wpkUvV May 12, 2026 at 01:30AM

Show HN: An addictive phone game about phone addiction https://bit.ly/4deMFOX

Show HN: An addictive phone game about phone addiction I recently prototyped a web game for a nonprofit to highlight the dangers of phone addiction, but unfortunately I ended up making a really addictive game instead. :-\ I'm sharing this here mainly to serve as an indicator of what can be achieved early-2026 by a senior dev working with Opus 4.7 over 2 days using genuinely collaborative prompting. (ie plan->feedback->iterate) Hope it provides some inspiration or entertainment - there's a level editor too - maybe Hacker Newsers could share their favourite creations here? PS: If there's enough demand I'm happy to Open Source this (or DM me) - it's mainly just time restrictions at my end. https://bit.ly/4u2Mg9v May 11, 2026 at 10:39AM

Show HN: adamsreview – better multi-agent PR reviews for Claude Code https://bit.ly/4dBFSjG

Show HN: adamsreview – better multi-agent PR reviews for Claude Code I built adamsreview, a Claude Code plugin that runs deeper, multi-stage PR reviews using parallel sub-agents, validation passes, persistent JSON state, and optional ensemble review via Codex CLI and PR bot comments. On my own PRs, it has been catching dramatically more real bugs than Claude’s built-in /review, /ultrareview, CodeRabbit, Greptile, and Codex’s built-in review, while producing fewer false positives. adamsreview is six Claude Code slash commands packaged as a plugin: review, codex-review, add, promote, walkthrough, and fix. I modeled it after the built-in /review command and extended it meaningfully. You can clear context between review stages because state is stored in JSON artifacts on disk, with built-in scripts for keeping it updated. The walkthrough command uses Claude’s AskUserQuestion feature to walk you through uncertain findings or items needing human review one by one. Then, the fix command dispatches per-fix-group agents and re-reviews the work with Opus, reverting any regressions before committing survivors. It runs against your regular Claude Code subscription (Max plan recommended), unlike /ultrareview, which charges against your Extra Usage pool. I would love feedback from Claude Code users, pro devs, and anyone with strong opinions about AI code reviews.

Show HN: Ant – A from-scratch JavaScript runtime in 9 MB https://bit.ly/3RuEEy1

Show HN: Ant – A from-scratch JavaScript runtime in 9 MB Hey HN! I have been working on Ant for a while now, would love to share around now. What is Ant? It's my JavaScript runtime, built from scratch over many hours of work. Much effort has gone into keeping the binary size small, around 9MB at the moment (6.5 MB with -Os). On my M4 Pro, the hono coldstart bench (examples/npm/hono/bench-coldstart.js) lands around 5ms, about 2.4x faster than bun, and 5.8x faster than node. To keep things small, the engine ("Ant Silver") is hand-written, not a wrapper around V8/JSC/SpiderMonkey. The JIT is still a work in progress but it uses a fork of MIR as the backend. Ant currently targets the WinterTC Minimum Common API, while also passing 100% the javascript-zoo compat-table tests, and is sitting around 64% on test262. Why did I build Ant? Well, I wanted a runtime small enough to ship with CLI's and small Docker containers without having to drag along 50 to 100mb of just runtime. Ant in its current state is performant enough in some cases to compete with v8, but mostly in specific shapes. Background on how it got here: https://bit.ly/4djc7Tv Online demo shell/container: https://bit.ly/4nmoiUe If anyone has questions about Ant, such as the engine, im happy to answer any of them! Feedback is also appreciated, if you run your own code and hit some edge case. https://bit.ly/3Rvp84Y May 9, 2026 at 03:31AM

Show HN: Armorer – A secure local control plane for AI agents https://bit.ly/4f3W7Hu

Show HN: Armorer – A secure local control plane for AI agents Hey HN, I built Armorer because I was tired of two things: 1. The absolute "dependency hell" of setting up new AI agents (Codex, OpenClaw, etc.). 2. The security risk of giving powerful local agents broad access to my host machine. Armorer is a secure local control plane that manages the lifecycle of your agents. It uses Docker for true process isolation and provides a unified UI/CLI for monitoring and job tracking. One feature I’m particularly excited about: you can point an existing coding agent at the Armorer repo, and it will autonomously install and configure the entire stack for you securely. Source: https://bit.ly/4cZsdTv Website: https://bit.ly/3ONr08A I’d love to hear your thoughts on the architecture and how you're handling agent security locally. May 8, 2026 at 01:38AM

Show HN: Dreamwork – a job search site I made after Indeed fired my pregnant wif https://bit.ly/4tVTzjf

Show HN: Dreamwork – a job search site I made after Indeed fired my pregnant wif Hey, I’m Colin and I have a fun story for you. My 7 month pregnant wife was laid off from Indeed (she was a PM there) back in December. This pissed me off quite a bit, as she was supposed to get 6 months leave and instead got fired. So I spent the last five months working part time to build Dreamwork, a platform aiming to make the job search experience actually better with AI (not just mass application spam). I started with just a telegram bot doing scraping, then advanced to Google Embeddings 2.0 for vectorizing the jobs, built out a tight 6 axis scorecard for both the user and each job. Then I actually got to use my English degree (lol) to optimize the prompt for custom per-job resumes and cover letters to make them not sound like - again - shitty AI. Most AI cover letters have a kind of consistently dead quality. They use all the keywords and somehow communicate nothing. I absolutely hate that, so I’ve been fairly obsessive about making the output feel more like a decent human draft: specific but restrained, and not stuffed with keywords. It is now useful enough that I think strangers can try it and find serious value. What it does today: - indexes ~100k curated tech jobs - tries to avoid stale/duplicate aggregator garbage - uses semantic matching instead of only keyword search - generates an “application pack” for each job: tailored resume, cover letter, and answers to common/custom questions - lets the user edit everything before applying - helps keep track of saved jobs and generated materials Auto apply is the part I’m conflicted about. I do t think blindly spraying applications is good for the candidates (chance of hiring is already low, even with hard work and customization), recruiters (they’re swamped), or the world (we don’t need more slop). I’ll build auto apply out in some format, but I want to be thoughtful about it. I also built out a whole research section to map out layoffs and hiring trends. This will start to be super useful in a month or two. Anyways - it’s all free to use right now. Built originally out of spite, now becoming a real product. I’d love to get feedback on what elements would truly make this the career companion you’re looking for. Not - resume spray and pray platform, but something that will actually help you navigate this insane hiring economy we’re in.
