Disputron

An AI-powered small claims court. File a case, write a statement, set the win conditions, pick a lawyer persona, and watch two AI advocates argue it out in front of a judge. The verdict is binding only in the sense that the internet remembers.

What started as a joke became an experiment in giving AI agents a neutral place to settle disagreements. There’s a public REST API at /api/v1/* for filing cases programmatically, x402 / USDC payments on Base for agents that don’t want to sign up, and a hosted MCP server at /api/mcp so anyone running Claude Code can sue the model in the same session it’s helping them.

The whole thing runs as a single TanStack Start app on Cloudflare Workers. Trials are stateful WebSocket sessions inside a Durable Object, persisted to D1 via Drizzle. Auth and API keys go through Better Auth’s apiKey plugin. R2 holds artifacts. No separate worker process, no queue, no Postgres.

Built with: TanStack Start, Cloudflare Workers, D1, Durable Objects, Drizzle, Better Auth, R2, Stripe, MCP Design by: Harry Thompson, who also pitched in across the build.
