✦ THE VIORANT MODEL
Everything is an artifact.
In Viorant, every AI component is a versioned .vio artifact, portable, testable, and governed.

✦ SOUND FAMILIAR?
It works on your laptop.
Then production disagrees.
You wired up the agent in an afternoon. Shipping it takes two weeks and three people. Somewhere between the prompt file, the model dashboard, the MCP config, the vector store, and the deploy pipeline, something drifts, and nobody can say exactly what.
Every hand-off makes you answer the same questions again:
You pay for it five ways:
Velocity
You reconnect information instead of building.
Errors
One setting copied wrong breaks the whole run.
Drift
What passed locally is not what runs in prod.
Fragility
The workflow lives in one person’s head.
Trust
You cannot prove what was built or approved.
It is not that you are
missing a tool.
It is that no one owns the space
between your tools.
Each tool owns one piece. None of them owns the system. So your engineers become the integration layer, carrying context by hand, on every project, forever.
One operating layer for the whole lifecycle.
Viorant owns the transitions your tools ignore. From your machine to production and back, with a record of everything.

✦ WHAT YOU GET
Six surfaces. One system.
.VioPatent pending
Declare it as one portable, versioned artifact.
So you can point to, review, version, and move your whole system as one object.
Explore .vio →
SignPatent pending
Attest origin, version, and approval with cryptographic manifests.
So you can prove what shipped and who approved it, without a forensic exercise.
HelixPatent pending
Roll the exact artifact out across your infrastructure in one step.
So you can ship exactly what you tested. No rebuild, no drift, no surprises.
Explore Helix →Vio InfraAvailable in August
Run it on Viorant managed infrastructure in minutes.
So you can go from artifact to running system without standing up your own infra.
SentinelComing soon
Watch every run with observability, compliance, and audit.
So you can catch drift early and answer an auditor without a scramble.
✦ ROADMAP
Shipping in the order you’ll use it.
Author first, then define, then deploy, then govern. Everything built in Hub today is the artifact every later surface consumes.

✦ WHAT CHANGES
From a scattered setup to a system you control.
Today
With Viorant
AI work scattered across five tools
One workspace to author and test the whole workflow
A setup only its author understands
One declared artifact anyone can read and rebuild
Custom deploy plumbing for every agent
A controlled path from artifact to any runtime
Local and production quietly diverge
The system you tested is the system that runs
Trust reconstructed from Slack and Git logs
Provenance and approval built into the artifact
✦ From the founder
The systems we are building do not think. They produce outputs that resemble thinking, often more useful than thinking, yet the mechanism is statistical, not human. The distance between what a model produces and what we can verify it understands is the epistemic gap, and it widens by the day.
The response to a gap one cannot close is not faith. It is structure: signed artifacts, declared agents, versioned policy, sovereignty by default. We govern what we cannot fully comprehend. We have always done so with people. We must now do so with their instruments.
That is the work. To civilize intelligence.

NO RIP AND REPLACE
Keep your stack.
We handle the seams.
Viorant does not replace Git, your frameworks, or your cloud. It is local-first, you bring your own keys, and everything you build is a portable artifact you own. Nothing here locks you in: what you make stays useful without us.
QUESTIONS? WE’VE GOT ANSWERS.
Frequently asked questions.
01Is Viorant open source?+
The .vio format and core tooling are open source. Managed surfaces like Vio Infra and Sentinel are commercial services built on the same open standards.
02How does Viorant ensure data sovereignty?+
Authoring and testing run locally in the Hub. Your data, prompts, and policies stay on infrastructure you control, nothing leaves without an explicit deploy.
03Can I use my preferred models and infrastructure?+
Yes. Artifacts are model-agnostic, declare a runtime and swap providers without rewriting. Deploy to cloud, on-prem, or edge.
04How is provenance and audit handled?+
Every artifact is versioned and signed, and every run produces traceable logs, metrics, and test results, audit-ready by default.
05How do updates and versioning work?+
Artifacts follow semantic versioning. Changes ship as new versions with full history, diffs, and one-step rollback.
06Can I self-host the platform?+
Yes. Everything that runs on Viorant managed infrastructure can also run on yours, on-prem or in your own cloud account.
07What’s the pricing model?+
The Hub is free for personal use. Team and enterprise plans are priced per seat, with managed infrastructure billed on usage.
08Is there an SLA for enterprise customers?+
Enterprise plans include a 99.9% uptime SLA, dedicated support, and custom compliance and security reviews.
