Don't ship AI
you can't govern
The open-source governance layer that runs inside your stack — enforce policies locally, keep every prompt in your own infrastructure, and stream a tamper-evident decision log to your dashboard. No proxy. No data egress. No $50K contract.
Join the waitlist for early access:
Production-ready from day one
AI governance is broken
Every option forces a tradeoff that shouldn't exist. Expensive or incomplete. Secure or usable. Fast to deploy or audit-ready.
Enterprise vendors want $50K+ and a 6-month pilot
By the time you're onboarded, you've missed three compliance deadlines.
Proxy-based tools route your data through their servers
Your security team vetoes it. Your users' data leaves your VPC.
Their platform goes down, your AI goes dark
Governance should protect your product, not become a single point of failure.
Open-source libraries give you detection — but no proof
The auditor doesn't care about your regex. They want a trail you can export.
Overrule eliminates these tradeoffs entirely.
Three steps. Zero config.
No infrastructure. No sidecars. No proxy. Just import and call.

Every design decision exists
because alternatives failed here
Not a prototype. Not a wrapper. Not a proxy. Production infrastructure that solves the problems other tools create.
Fail-Open — Governance ≠ Outage
Other platforms go down, your AI goes dark. Overrule fails open. SDK errors never crash your application. Your uptime is sacred, not sacrificed for governance.
In-Process — No Proxy Tax
Policies evaluate locally, in-process — typically sub-millisecond on real-world prompts, with no network round-trip on the hot path. While others add 50-200ms per request routing through their proxy, we never sit between you and your provider.
Audit Trail — Prove, Don't Promise
Every governed call produces a structured decision record: timestamp, model, policies applied, violations with severity, and latency. Your prompts and completions never leave your infrastructure — only governance metadata is streamed.
Multi-Provider — No Lock-In
OpenAI and Anthropic today, more providers coming. Switch between them without touching governance logic. Other tools lock you into their proxy and their provider partnerships.
Your Rules, Your Code — Ship in Minutes
PII, injection, toxicity built-in. Streaming interception, LangChain callback, policy hot-reload. Need custom rules? Subclass BasePolicy. No tickets, no vendor timelines.
Battle-Tested Resilience
Circuit breakers, exponential backoff, bounded buffers, graceful shutdown. Production infrastructure with fail-open resilience from day one.
Enterprise governance without
the enterprise baggage
Existing solutions force you to choose: expensive platform with a 6-month rollout, or fragile DIY scripts with no audit trail. Overrule is the third option.
Overrule is what happens when you build governance for developers, not for procurement teams.
Compliance infrastructure
doesn't build itself
the week before a deadline.
The EU AI Act's high-risk obligations (Articles 13-15) were deferred to December 2027 under the Digital Omnibus — but transparency rules under Article 50 apply from August 2026, and the logging infrastructure you'll need doesn't appear overnight.
Overrule gives you runtime enforcement and a real decision trail now, so compliance is a switch you flip — not a fire drill.
