Show HN: ClaudeCraft – Minecraft server where Claude agents do everything

Sun, 02/15/2026 - 8:37pm

Hi everyone,

I created a Minecraft server where Claude agents do everything - you just watch and give commands. You can add new bots and ask them to do anything in the world. Users are just spectators, so all the tasks are executed by bots you create. It uses mineflayer and claude agent sdk under the hood to plan and execute tasks.

I used minecraft 1.21.11 java edition and you can add the server with the following address: claude-craft.com

Show HN: Crabify, a Spotify TUI

Sun, 02/15/2026 - 8:16pm

Hey HN,

I made a little Spotify TUI today because I was sick of the electron app draining my battery and otherwise slowing down my computer. I am using it right now and figured you all might find it useful.

Spotify doesn't seem to allow devs to create new apps at the moment, but this should work with any existing or unused app id.

Cheers!

Show HN: I replaced my SaaS stack with a single AI agent running on a Mac Mini

Sun, 02/15/2026 - 8:10pm

After burning $500/month on various SaaS tools (CRM, social media scheduler, customer support), I built a custom AI agent using OpenClaw (https://github.com/openclaw/openclaw) that handles all of it.

The agent runs 24/7 on my Mac Mini. Key capabilities: - Monitors and replies to Instagram DMs - Generates and posts content across platforms - Tracks competitors and market trends - Writes daily business reports - Self-evaluates and improves weekly

I've published 24 reusable skills on ClawHub (https://clawhub.com) that anyone can install.

The thesis: SaaS is renting software. AIaaS is installing labor. One AI agent with the right skills replaces 5-10 SaaS subscriptions.

Two weeks in, honest results: - Saved ~15 hours/week on repetitive tasks - Customer response time: hours → minutes - Still learning to stop it from over-engineering everything

Code and skills are open-source. AMA.

Show HN: MarginDash – See which AI customers are profitable

Sun, 02/15/2026 - 7:46pm

I built MarginDash because I couldn't answer a basic question: which of my customers actually make me money after AI costs? My Stripe dashboard showed revenue going up. My OpenAI bills showed costs going up faster. I had no way to connect the two at the customer level. MarginDash is a few line SDK integration (TypeScript, Python, or REST) that tracks model usage per customer and connects it to revenue — either through Stripe sync or by passing revenue directly in the API call. You get a per-customer P&L showing revenue, cost, and margin.

A cost simulator lets you pick any feature, swap the underlying model, and see projected savings. Models are ranked by intelligence-per-dollar using public benchmarks (MMLU-Pro, GPQA, AIME) so you can find cheaper options that aren't actually worse. Budget alerts email you before a customer or feature blows past a threshold.

The pricing database covers 100+ models across OpenAI, Anthropic, Google, AWS Bedrock, Azure, and Groq with daily updates — so cost calculations stay accurate without you maintaining a spreadsheet. The SDK only sends model name, token counts, and customer ID. No prompts, no responses.

Solo founder, built the whole thing for $239.72 in AI costs (wrote about that too). Currently free while I get feedback — would love to hear what you think, especially about the cost simulator.
