Governed agent runtime · bring your own model

Bring your model.
We bring the harness.

AgnarOS is the audit-grade execution platform for LLM agents — for any team that needs to trust what its agents do. You keep your provider and your keys. We give you the governed runtime: every decision composed, gated, and signed.

No tokens resold. Your keys, your inference. · Every run replayable · 21 CFR Part 11

Why AgnarOS

Move AI from party trick to production engine.

Most companies — whatever their size — are stuck with AI that summarizes an inbox or answers like a search box. AgnarOS turns that into a resilient, scalable, secure engine your business can actually run on.

AI today · the toy

A clever assistant

  • Summarizes your email, drafts a note
  • Answers like a smarter search box
  • Ungoverned, unprovable, off the record
  • One-off prompts that break at scale
AI on AgnarOS · the engine

A system you run on

  • Runs real workflows end-to-end
  • Resilient, scalable, secure by design
  • Every decision gated, signed, replayable
  • Composable, versioned, and owned by you
The model

Compose agents from typed, versioned Building Blocks.

Prompts, model configs, output schemas, MCP tool bindings, shell profiles, validators and policy bundles — assembled declaratively into a Harness. No glue code. Every block is pinned to an exact version, so a certified agent stays certified.

How AgnarOS works: compose typed Building Blocks, declare a versioned Harness, execute a policy-gated graph with your own model (BYOK), and prove it with a signed, immutable Decision Trace.
Building Blocks → a single governed Harness · composed, then sealed and provable at the base
01 / COMPOSE

Building Blocks

Reusable, typed units from the Catalog — prompt, model, schema, MCP binding, policy.

02 / DECLARE

Harness Descriptor

A versioned spec wiring blocks, parameters and policies. Composable and nestable.

03 / EXECUTE

Execution Graph

A typed DAG — llm.call, tool.call, human.approval — gated at every node.

04 / PROVE

Decision Trace

An immutable, signed, replayable record of exactly what ran, and why.

Why teams standardize on it

Governance is the product — not an afterthought.

001

Compose, don't code

Agents are declarative assemblies, not scattered Python scripts. Anyone can build; everyone inherits the same controls.

002

Govern by default

Policy Gates evaluate cost caps, model allowlists, tool scope and mandatory human approvals on every node — and log each one.

003

Capitalize across the org

Blocks move through a lifecycle — experimental → reviewed → approved → certified — with peer review and deprecation built in.

004

Audit-grade traceability

Every execution is a signed, replayable Decision Trace. Not logs after the fact — evidence by construction.

Open by design

Your models. Your stack. No lock-in.

AgnarOS runs on proven, open foundations and stays model-agnostic — plug in the providers and tools you already trust.

One platform, many domains

Built for any team that puts agents to work.

AgnarOS is domain-agnostic. The same governed runtime serves finance, operations, legal and the most regulated labs alike — you bring the use case and the model.

And beyond

Your workflow

If an agent touches a real system, it belongs on a harness you can govern — and prove.

Bring your own model

Your keys never leave their vault.

AgnarOS is provider-agnostic by design. You supply the inference; we never resell tokens or lock you to a model.

  • Last-moment decryption. The key is unsealed in memory, used for one call, then forgotten. No persistence, ever.
  • Provider gateway. Route to Claude, GPT, Bedrock or any OpenAI-compatible endpoint from your config — not a hardcoded default.
  • Policy-pinned models. Gate by data classification — e.g. PII routes only to EU-sovereign models.
  • Per-user ownership. Keys are scoped to you and never shared without an explicit workflow.
How we engage

No subscriptions. No per-seat rent. We build it with you — then hand you the keys.

AgnarOS isn't another monthly SaaS bill. We stand up your platform, train your people, and leave you owning a production engine — your cloud, your keys, your data.

01

We build the infrastructure

We stand up AgnarOS on your own cloud and wire it into your systems — production-grade from day one.

For you → A real platform, not a pilot that stalls.
02

We train your team

We upskill your people to compose, govern and operate agents themselves — no black box.

For you → Independence and capability that compound.
03

You own it — no recurring fees

No subscription, no per-seat or per-token rent. The runtime, the keys and the data are yours.

For you → Predictable cost and full control.
Your journey

In control at every step — and clear on what you get.

What's in it for youResilient, auditable AI that scales with demand.
Governance that scales to the strictest bar

If you can pass an audit, everything else is easy.

Most teams just want control and a clean record of what ran. Regulated teams have to prove it — so we engineered for that strict end. Every other team inherits the same guarantees for free: signed, Object-Locked, replayable Decision Traces.
