Treat Appian like a real codebase.

Hadrian is an AI agent that turns plain-English change requests into shipped Appian applications. No more click-through Designer.

Plain English in, shipped Appian out.

Briefs become record types, interfaces, migrations, deploys. Your team spends hours on the work that actually moves the project, not click-through Designer.
Your Appian. Your repo. BYOK end-to-end.

Hadrian runs against your existing Appian via the standard Deployment REST API. Ships standard package zips your team imports through your existing review gates.
Engineered, not vibe-coded.

Deterministic generators with round-trip-tested SAIL behind the LLM — not a prompt that hopes. Built for Appian 25.x+.

How it works

1
Spec.

Write the change in plain English.
2
Generate.

Hadrian transpiles the spec into typed SAIL, schema migrations, and an Appian package zip.
3
Deploy.

Package imports through your Appian Deployment REST API. Your environments, your gates.

Which Appian versions are supported?

Hadrian supports Appian 25.x and 26.x. New Appian releases are typically validated within days of launch.
What do I need to bring?

An Appian environment and a Claude subscription.
Does Hadrian see my code or data?

Hadrian does not store your code, data, or credentials. It works against your Appian environment in-place and ships changes through Appian's standard deployment flow.
What can Hadrian build today?

All Standard Tier Appian application objects.

BYOK setup. Hadrian runs against your Appian via the Deployment REST API.
