01 Open source requirements engineering
Requirements engineering, without losing traceability.
Structure requirements, connect verification, approve revisions, and freeze trustworthy baselines in one open platform.
- Open source
- Self-hosted
- ReqIF
- REST API
02 Requirements
Every requirement has a history.
Organize requirements hierarchically, review changes in context, and preserve the versions behind every approval. Comments and project roles keep decisions attached to the engineering record.
- Hierarchy
- Version history
- Review
- Approval

Conceptual product representation — not live project data.
03 Traceability
Coverage you can inspect.
Connect requirements to verification and see gaps, coverage, and suspect links as the design changes.

Requirement versions and traceability state captured together.
Conceptual product representation — not live project data.
04 Baselines
Freeze a trustworthy project state.
An immutable baseline records the exact requirement versions and traceability state at a point in time. Compare it with current work or export the captured state as ReqIF.
- Immutable snapshot
- Compare against current
- ReqIF export

07 Developers
Start local. Go deeper.
Run Marreq, integrate the API, or inspect the architecture. The complete documentation remains in the repository.
Run locally
Docker Compose starts PostgreSQL; Rust runs the API; Node.js 20 serves the SPA.
docker compose -f docker/docker-compose.yml up -d db
./marreq-core/scripts/db_setup.sh --seed
cargo run -p marreq-server
cd frontend && npm install && npm run devUse the web interface
Work with hierarchy, approvals, verification, matrices, baselines, project authorization, and exchange formats.
- Requirements and versions
- Verification records
- Traceability and coverage
- Baselines and exchange
HTTP API
JSON under /api, with session authentication for the browser and Bearer tokens for headless clients.
curl -s http://127.0.0.1:8000/api/auth/me
curl -s http://127.0.0.1:8000/api/projectsTechnology and layout
Rust, Rocket, Diesel and PostgreSQL behind a React 19 and TypeScript interface.
- Rust workspace
- React SPA
- PostgreSQL + optional pgvector
- ReqIF, Excel and MCP integrations
