ARC provides a spec-as-source development platform for AWS backend teams, combining an AI-native spec editor called ARCitect with a deterministic code generator called Code Reactor. The platform turns natural-language intent into validated OpenAPI specifications, then generates complete AWS backends—including handlers, infrastructure, tests, and CI/CD—in a single pass. This approach eliminates spec drift by making the OpenAPI contract the single source of truth from which all code artifacts are derived.

Problem
Backend teams struggle to keep OpenAPI specifications in sync with actual implementation code, leading to spec drift where the contract becomes a misleading artifact within weeks. AI coding agents can worsen this problem by generating plausible code that doesn't actually conform to the specification, causing integration failures, skipped contract tests, and production incidents that surface through alarms, bad reviews, or churned customers.
Solution
ARC provides a spec-as-source development platform where the OpenAPI specification is the single source of truth and all code is a derived build output. The platform consists of two core components: ARCitect, an AI-native spec editor that converts natural-language intent into validated, production-grade OpenAPI documents, and Code Reactor, a deterministic generator that produces complete AWS backends in a single pass. Code Reactor generates TypeScript handlers, DynamoDB access patterns, CDK infrastructure, IAM configuration, contract tests, CI/CD pipelines, and documentation—all regenerated together whenever the spec changes. This approach makes spec drift architecturally impossible because there is no path for a handler to disagree with the spec when the handler is materialized directly from it.
Target Audience
Primary customers are backend engineering teams on AWS who have adopted design-first API development and need enforcement to prevent spec drift, particularly those integrating AI coding agents into their workflows.
Features
- ARCitect AI-native spec editor with agentic workflows that turns natural-language intent into validated OpenAPI, with real-time validation and context orchestration at the system level
- Code Reactor deterministic generator that produces complete AWS backends in a single pass—no iteration loops, no agent thrash
- Generated artifacts include TypeScript handlers, DynamoDB access patterns, CDK infrastructure, IAM configuration, contract tests, CI/CD pipelines, and documentation
- Spec validation catches inconsistencies before they become bugs, keeping data models, contracts, and code modules consistent
- Zero-drift deployment model where all downstream artifacts are derived from the spec and regenerate together on any change
- OpenAPI as the foundational format, leveraging its mature tooling ecosystem and standards body support
