Ask HN: AI Agents vs. Gateways vs. Harnesseshttps://news.ycombinator.com/item?id=47397737Hi,I'd like to get everyone's take on the different components in the AI Agents ecoysystem. I find the current terminology quite confusing as it's not always obvious what I'll be actually getting when I examine the available options.A lot of things get called Agents, but that term seems hard to define as it often refers to overlapping functionality. To me, agents seem to be currently composed of the following components:## Harnesses- Adds UI and system instructions around an LLM and may also augment it with tools such as memory, tool calls, etc...- Examples are Claude Code, Code, Gemini CLI, pi.dev, ...## Gateways- These connect agents to your communication tool of choice, e.g. Whatsapp, Telegram, Slack, Discord, ...- Examples are OpenClaw and Nanoclaw## Sandboxes- Isolated environments where Agents can run with limited or auditable capabilities- Examples can be from physical ones like separate Mac Minis to docker-agent, agent-sandbox, localsandbox, ...This then takes us to *Agents*:##Mar 16, 2026 11:43 AM

Show HN: Dumped Wix, my AEC consultancy's storefront is now an AI Edgehttps://axoworks.com/I run a building design consultancy for homeowners and architects, not a SaaS firm. Honestly, I'm not going to claim we were trying to build some fantastic ‘anti-fragile alternative’ for the future… I just got tired of paying Wix $40 a month for a brochure no one read. The portfolio was static, the inquiries were generic, and every time a potential client asked about setback variances, I'd lose hours explaining the same thing. So last December, I told my wife I was killing the website. She thought I’d lost it. Maybe I had.The stack? It’s messy. We started on Netlify because it was cheap. Hit that stupid 10-second serverless timeout after a week when I started customizing the bot. The bot would just… freeze. Had to implement a clunky polling loop that felt like a band-aid. Eventually split the agent into 3 pieces just to keep it responsive:The Brain (Edge) figures out what you want, shoots a JSON signal to the browser.

Show HN: Reviewd – A free, local alternative to Claude Code Review(no API costs)https://github.com/simion/reviewdAnthropic just launched their official Claude Code Review tool, pricing it at $15–$25 per PR. If your team is shipping 10+ PRs a day, that model scales terribly.Even before their launch, I was running a custom local Claude agent for my team to review PRs. The feedback was great and it caught real bugs, but the workflow was a massive time sink. I was manually invoking "claude --agent .. branch_name", grab the output, filter it and post the relevant comments.So I built reviewd to automate the local execution: https://github.com/simion/reviewdIt is a Python-based background daemon that runs on your machine or a VPS.How it works: 1. It polls GitHub/BitBucket for open PRs. 2. Creates a near-instant git worktree (no re-cloning). 3. Optionally runs your actual local test/lint commands (the AI gets the stdout/stderr). 4. Pipes the context into the Claude, Gemini, or Codex CLI you already have installed. 5. Parses the JSON output and automatically posts structured inline and summary comments toMar 11, 2026 4:43 PM

Show HN: Ink – Deploy full-stack apps from AI agents via MCP or Skillshttps://ml.ink/Hi HN, I built Ink, a full stack deployment platform where the primary users are AI agents, not humans.We all know AI can write code, but deploying them still requires a human to wire it up: hosting, databases, DNS, and secrets. Ink gives agents those tools directly.The agent calls "deploy" and the platform auto-detects the framework, builds it, deploys it, and returns a live URL at *.ml.ink. Here's a demo with Claude Code: https://www.youtube.com/watch?v=F6ZM_RrIaC0.What Ink does that I haven't seen elsewhere:- One agent skill for compute + databases + DNS + secrets + domains + usage + metrics + logs + scaling. The agent doesn't juggle separate providers — one account, one auth, one set of tools.- DNS zone delegation. Delegate a zone once (e.g. dev.acme.com) and agents create any subdomain instantly — no manual adding DNS records each time, no propagation wait.- Multiple agents and humans share one workspace and collaborate on projects. I envision a future where many agents collaboratMar 11, 2026 3:39 PM

I Got Fired Because of AI – But I Still Think I'm the Engineer of the Futurehttps://news.ycombinator.com/item?id=47328448Over the past few months I completely rebuilt my approach to software development.I used to write code myself. Now I strategically manage neural networks.Before, I spent time on architecture, reading documentation, and understanding other people's code. Now I spend my time choosing the right model and discussing on Twitter which one is the real game changer.I bought all the most expensive AI coding tool subscriptions. About $500 in total. Honestly, I feel sorry for people who haven't done this yet. I'm subscribed to all the founders of AI dev tools and read their posts religiously. If someone claims their product can replace a mid-level developer, I see it immediately. You have to stay ahead of the market.I used to worry when I didn't understand some complex part of the system. Now I usually don't understand what the neural networks wrote for me — but that's fine. I read on Twitter that reading and understanding code is becoming obsolete.

Show HN: PolyClaude – Using math to pay less for Claude Codehttps://github.com/ArmanJR/PolyClaudeHi HN!I built this tool specifically for Claude Code users who hit the 5-hour rate limit wall mid-flow. There's no official plan between Pro ($20/mo) and Max ($100/mo). it's a fixed gap with nothing in between.The workaround most people do manually: running multiple Pro accounts and switching when one is limited. This actually works, but naive rotation wastes a lot of capacity. When you activate an account turns out to matter as much as which one you use. A single throwaway prompt sent a few hours before your coding session can unlock an extra full cycle.PolyClaude automates this. You tell it your accounts, your typical coding hours, and how long you usually take to hit the limit. It uses combinatorial optimization to compute the exact pre-activation schedule, then installs cron jobs to fire those prompts automatically. When you sit down to work, your accounts are already aligned.It's free and open source. Install is one curl command, then an interactive setup wizard handles the rest.RMar 7, 2026 10:24 PM

Show HN: Mnemora – Serverless memory DB for AI agents (no LLM in your CRUD path)https://github.com/mnemora-db/mnemoraHi HN,I built Mnemora because every AI agent memory solution I evaluated (Mem0, Zep, Letta) routes data through an LLM on every read and write. At scale, that means 200-500ms latency per operation, token costs on your memory layer, and a runtime dependency you don't control.Mnemora takes the opposite approach: direct database CRUD. State reads hit DynamoDB at sub-10ms. Semantic search uses pgvector with Bedrock Titan embeddings — the LLM only runs at write time to generate the embedding vector. All reads are pure database queries.Four memory types, one API: 1. Working memory: key-value state in DynamoDB (sub-10ms reads) 2. Semantic memory: vector-searchable facts in Aurora pgvector 3. Episodic memory: time-stamped event logs in S3 + DynamoDB 4. Procedural memory: rules and tool definitions (coming v0.2)Architecture: fully serverless on AWS — Aurora Serverless v2, DynamoDB on-demand, Lambda, S3. Idles at ~$1/month, scales per-request.

I built it over the last few days using Claude and a lot of vibe coding.The idea came from my own investing workflow: I often look at companies through the lens of specific investors (Buffett, Lynch, Taleb, etc.). I wanted a tool that could generate investment ideas filtered through those frameworks.What the app does:You choose an investor (Buffett, Lynch, Soros, Damodaran, etc.) and an asset class (stocks, startups, crypto). The app then generates 10 opportunities and explains why that investor might find them interesting, based on their known principles.Under the hood: • Node.js server (no frameworks) • Vanilla JS frontend • GPT-4o for research / synthesis • live price data • Stripe + Google OAuth • hosted on RailwayIt’s still an experiment and I’m curious if the idea actually makes sense to other investors.You can try it here:https://www.moatradar.comHN users can get 10 free credits:https://www.moatraMar 4, 2026 11:25 PM

Show HN: TypeShim – .NET WebAssembly Meets TypeScripthttps://github.com/ArcadeMode/TypeShimI'm a big proponent of WebAssembly and .NET. When I found out .NET now runs in the browser on WASM with ánd without Blazor, I figured that could be something. Since Blazor is often too big of a step for TypeScript developers, I figured the recently added ability to include a .NET WASM app as a library in a JS bundle could be a good stepping stone for WASM to gain some ground in this JS-heavy web we have.Using the JSExport/JSImport interop is relatively cumbersome, it only supports static methods, has no OOP concepts (like classes, just object handles) and it requires manually writing TypeScript definitions for the exported methods. So I decided to try and make some tooling that would improve the developer experience and reliability higher.Enter TypeShim: a codegen tool that creates a seamless programming experience between .NET WebAssembly and TypeScript. Complete class level exports are translated to C# codegen to automatically define your JSExports/JSImports with a TypeScript class tMar 3, 2026 9:55 PM
