Show HN: Bench-Bets – A World Cup Prediction App Built with Nuxt and SQLite

Hacker News - Tue, 05/19/2026 - 2:10pm

I’m sharing the 3rd version of a side project I’ve been building for every major tournament since 2022. It’s called Bench-Bets, and it’s a simple way to run prediction leagues for the 2026 World Cup with friends.

During Euro 2024, the app reached 7,000 users. I was running it on Fly.io and, despite the great DX, I realized I hadn't spent enough time on my caching strategy. I ended up hitting over 100GB of outbound traffic in a month for what is essentially a text-heavy app. For v3, I’ve spent my time rethinking the data-fetching architecture and ensuring I'm not "re-downloading the world" on every match update.

The tech-stack:

- nuxt v4 & tailwind

- sqlite + drizzle ORM. I’m a huge advocate for SQLite in production for these types of hobby apps—it’s fast, simple, and the performance for thousands of concurrent users has been surprisingly solid

- auth: Better Auth

The rules: It’s the standard "guess the score" format, but I’ve added a twist where points double starting from the Round of 16 to keep the leaderboard competitive until the very end.

I built this because I wanted an ad-free, tracker-free alternative to the cluttered betting apps out there. It’s just me and a few friends playing, but it’s been a fun way to learn about modern web architecture and the "surprises" that come with even modest scale.

Show HN: AgentShield – Stop AI agents from spending money unsupervised

Hacker News - Tue, 05/19/2026 - 2:06pm

I'm a recent grad from UMich and built AgentShield because agentic AI is moving fast but payment safety hasn't caught up. Agents are already being handed API keys, stablecoin wallets, and payment credentials - if one misbehaves, gets prompt injected, or makes a bad call, nothing understands the agent's intent well enough to stop it.

Every spend request runs through four checks before money is allowed to move:

1. Quantitative (Redis) - Is the agent within its daily budget? Is it sending the same transaction over and over?

2. Policy (Postgres) - Is the vendor blocked? Is the amount too high to auto-approve? Is the stablecoin/network/address allowed?

3. Semantic (Claude Haiku) - Does the stated goal actually match what's being purchased?

4. Goal Drift (Claude Haiku) - Is this purchase within what the agent is supposed to be doing at all?

Checks 1 and 2 run sequentially — if either hard-denies, Claude never gets called. Checks 3 and 4 run in parallel via asyncio.gather.

One verdict comes back: SAFE, SUSPICIOUS, or MALICIOUS.

Full product — live dashboard, auth, HITL approval flows, spend monitoring. Completely free.

Looking for feedback, especially from anyone running spending agents in production.
