Requirements as living documents, not static forms.
LyraTwo is a self-hosted product requirements management platform built for product managers, business analysts, and the engineering teams they work with. Requirements are versioned, linked, and lifecycle-managed — with an AI copilot that understands your project context.
Features
AI Copilot (Cmd+J)
Expand requirements into sub-requirements, generate acceptance criteria, decompose features into tasks, or research and insert findings — all within your project context.
Change Simulation
Simulate the impact of any change before committing. Traces typed dependency links transitively and surfaces every downstream requirement affected.
Version History & Rollback
Every change creates an immutable snapshot. Full version history with single-action restore. Preserves review comments, status transitions, and change rationale.
ReqIF Import/Export
Supports the ISO standard interchange format used by IBM DOORS, Polarion, Jama, and Codebeamer. Also exports PDF, DOCX, and Markdown.
Bring Your Own LLM
Uses LiteLLM for model abstraction. Configure Claude, GPT-4, Azure OpenAI, or a locally-hosted model via a single environment variable.
SSO & Access Control
Local accounts or OIDC SSO (Azure AD, Google Workspace, Okta, Auth0, Amazon Cognito). Role-based project membership: owner, manager, contributor, viewer.
Requirement lifecycle management
Every requirement follows a governed lifecycle with a full audit trail at each transition.
Deploys in your AWS account
A single ECS Fargate service backed by RDS PostgreSQL behind an ALB. The CloudFormation template deploys into your existing VPC — no new VPC created. Stack creation takes approximately 12 minutes.
Available on AWS Marketplace
Subscribe, view pricing, and deploy in minutes. Billed through your existing AWS account.
