Infrastructure for the AI era.

Built right. Ships.

brefwiz builds the infrastructure layer the AI era actually needs — from first principles, owned end to end, so the businesses built on it are never ambushed by the infrastructure they forgot to own.

aiguilleur.toml

# One env var. No more 429s.
OPENAI_BASE_URL=https://aiguilleur.yourco.internal/v1

# Reads live quota headers from every provider.
# When OpenAI is near its limit, traffic
# silently fails over to Anthropic.
# Your app never sees a 429.

The problem

The AI era didn't just change what you build.
It changed what can go wrong.

429

Rate limits you can't predict

Every other gateway round-robins or uses static weights. None of them read the actual quota state providers return on every response. You find out you hit the limit when your users do.

15m

Tokens you can't revoke

JWT tokens are valid until they expire. A compromised AI agent, a fired employee, a leaked credential — 15 minutes of damage before your denylist infrastructure kicks in. If you built it.

18mo

Infrastructure you keep rebuilding

Auth, LLM routing, quota management, scheduling, payments, workflow orchestration. Every marketplace founder rebuilds the same stack. 18 months before they can focus on their domain.

What we're building

Open source · Apache-2 + ELv2

quorumauth

In development

The auth layer AI-era applications actually need. Edge-native authentication with sub-second token revocation and a one-liner SDK. No round-trips to a central server. No 15-minute windows of compromise.

✓ Auth decision at the edge — zero latency penalty
✓ Sub-second revocation — compromised token, dead in <1s
✓ First class DX polyglot SDK
✓ Built for AI agents — quorum sign-off on sensitive actions

aiguilleur

In development

The honest LLM gateway. The only gateway that reads real provider quota state — not static weights, not round-robin — before routing your request. Your app never sees a 429 again.

✓ OpenAI-compatible drop-in — one env var
✓ Reads live quota headers before routing
✓ Distributed quota engine — no Redis bottleneck
✓ Per-org budget management API
✓ 4-layer response cache — coalescing, exact-match, provider prompt-cache passthrough, semantic (opt-in)

The platform

Later

Auth, LLM routing, Stripe Connect marketplace payments, scheduling, inventory, durable workflow orchestration — assembled and running. Build your AI-native vertical marketplace in 6 weeks, not 18 months.

✓ Battle-tested — we're building our own experience operator marketplace on it
✓ Stripe Connect — two-sided marketplace payments built in
✓ Durable workflows — long-running AI agents, no timeouts
✓ Multi-tenant from day one

Where this started

My family runs a touring business in French Polynesia. They were looking for a "calendar management app."

After digging into the actual problem, it turned out what they wanted was a full reservation platform with integration with operators and tourism agencies, a personnel management system, and an inventory platform.

That's a nice calendar, no?

I decided to help — and discovered the power of AI. I went down the rabbit hole. Hard.

I decided to build the platform I always dreamed of building and operating. brefwiz was born. And it will be magical.
