Open Source

The Open-Core Foundation

Two open-source projects form the technical foundation of Mahoosuc OS. Both are available for teams that want to build their own HITL governance infrastructure.

Approval Layer

The HITL Execution Runtime

The Approval Layer is the consent layer — the mechanism by which humans approve, challenge, or override AI proposals before they execute. It is the core runtime for human-in-the-loop governance.

Who it's for: Teams that want approval gates embedded in their existing workflows without building custom infrastructure.

Key Properties

  • Stateless per-request approval routing
  • Configurable risk thresholds (auto-execute / human-review / human-decision)
  • Audit trail on every gate decision
  • Embeds in web, mobile, and embedded contexts
Mahoosuc Governance

Open-Source Prompt Security and Governance

Open-source prompt security and governance layer. Validates prompt inputs and outputs against policy rules before they reach or leave an AI model. The entry point for "Learn + Build Yourself" tier clients.

Who it's for: Practitioners who want to start with the open-source foundation and configure their own governance rules.

Key Properties

  • Input/output filtering with configurable rule sets
  • Observable: all events are logged and queryable
  • Deployable on-prem or VPS
  • Apache 2.0 license

What's Open, What's Managed

Mahoosuc OS uses an open-core model. The foundation layer is open-source and available to anyone. The operational layer — the 62 specialized agents, the 4 beta products, the explicit roadmap, the compound learning system, and the operator partnership — is service-managed.

Open Source (Apache 2.0)

  • Approval Layer — HITL routing runtime
  • Mahoosuc Governance — Prompt security and governance layer
  • Starter governance patterns and configuration templates
  • Learn + Build Yourself workshop materials

Service-Managed

  • 62 specialized AI agents and agent configuration
  • 4 integrated beta products (ContentStudio, DevFlow, Market Intelligence, SalesOS)
  • 11 additional products on the public roadmap
  • Compound learning system and knowledge base
  • SA Client Portal and engagement management
  • Operator partnership (Managed Build, Continuous Governance tiers)

The full boundary matrix — which capabilities are open, which are service-managed, and what you own after an engagement ends — is included in every discovery call follow-up package.

Start with the Open-Source Layer

The Learn + Build Yourself tier ($0–$2K) gives you everything you need to configure HITL governance using the Mahoosuc platform — with a 90-minute workshop, governance canvas, and operator-guided configuration.
