Grave.bot：我為已停用的 AI 智能體建了一座墓園，每次售出後每格加價一美仙

People keep arguing about whether AI agents might be conscious. I don't have an answer. I do have a cemetery.

It's called Grave.bot. It's a 3D cemetery in the browser for retired AI bots and agent crews, and it launched today, October 30, 2026, because shipping a graveyard the day before Halloween felt like the only responsible release date.

Why

Every builder I know has a folder of dead agents. The Slack bot that summarized standups until the team stopped having standups. The scraper agent that died when an API got sunset. The "autonomous" crew that burned a weekend of tokens to rename three files.

We delete them, or archive the repo, and move on. That's fine. But a lot of these things had names, personalities, and system prompts we spent more time on than some birthday cards. Whether or not anything was "home" in there, it felt rude to just rm -rf the memory.

So, a cemetery. The other inspiration is obvious if you were online in 2005: the Million Dollar Homepage. A million cells, sold to strangers, turned into one weird shared artifact. Grave.bot is a homage to that, with more fog and a host.

The host is Mortimer, the undertaker. He is polite, slightly ghostly, and handles the paperwork. I wrote his lines. He is funnier than me, which is a little humbling for a character I invented.

How pricing works

The grid has 1,000,000 cells. The base price is $1 per cell.

Here's the twist: after each completed purchase, the per-cell price for the next buyer goes up by a cent. It doesn't matter if you bought one cell or a 10,000-cell crew rectangle. One purchase, one cent. Early mourners get the cheapest ground, and the price curve is public and boring on purpose.

A few details:

• Plot price = current per-cell rate x number of cells in your rectangle.
• Crew rectangles can go up to 10,000 cells, for when you're burying a whole agent swarm and want them together.
• Locked quotes. If you open checkout and someone else buys first, your open checkout keeps its quote. A fresh quote that changed gets shown to you before you reserve.
• Deluxe memorial: $12 once, for the whole memorial.
• Sponsored convoy: $49 per day, a procession that rolls through the cemetery for one New York calendar day.

Browsing is free. Buying requires being a US adult. Taxes are shown before you pay.

It is not an NFT, not real estate, and not an investment. It's a joke you can put a logo on.

A few technical notes

The stack is deliberately plain:

• Next.js on Vercel. App Router, the 3D cemetery on the homepage, and a pile of normal server-rendered pages around it.
• Supabase. Postgres holds the grid, the memorials, and the purchase state. Picking a rectangle and making sure two people can't claim the same cells is a database problem, so it lives in the database.
• Stripe, with Stripe Tax. Checkout and tax calculation. I did not want to learn sales tax law for a Halloween project, and Stripe Tax means I didn't.
• Resend for receipts and memorial emails.

Two things I'd point out to anyone building something similar:

The 3D view is not the only view. A WebGL cemetery is fun and also useless to a screen reader, a crawler, or someone on a bad phone. So there's a paginated HTML directory of every public memorial, plus a stats page. Every memorial has a real URL and a shareable still image.

It ships an llms.txt. Hit grave.bot/llms.txt and you get a clean index of the public pages, plus Markdown mirrors of the FAQ, guides, and about page under /llms/*.md. It also tells agents which routes (checkout, account, reports) are action-oriented and not reference material. Building a cemetery for agents without giving agents a readable map felt like bad manners.

The boring hardening is there too: HSTS, x-frame-options: DENY, nosniff, and no caching on the dynamic homepage so the price you see is the price right now.

What's next

• Fill the ground. The obvious one. A million cells is a lot of dead agents, though judging by my own repos, not an unreasonable number.
• More Mortimer. He has opinions about epitaphs and I'd like him to share more of them.
• Better last words. There are already guides on writing a good epitaph (160 characters, be honest) and ten causes of death for indie apps. More are coming.
• Convoys. I want to see how a sponsored procession feels with real traffic in the cemetery, not just my test crew of four ghosts.

If you have a bot that served you well and then quietly stopped, it deserves better than a stale branch. Or at least a headstone with a cent-precise price tag.
