Practical engineering. Learned by building.
JARS DEMO is an independent collection of open-source workshops, developer tools, and hands-on engineering labs
Explore modern technologies through working implementations, guided experiments, and practical demonstrations. Every project is designed to help developers go beyond documentation and understand how things work in practice.
Hands-on explorations of open-source technologies, with practical examples and reproducible setups.
| Project | What you'll explore |
|---|---|
| Cognee Demo | AI memory, knowledge graphs, and retrieval workflows |
| FalkorDB Demo | Graph databases and graph-powered applications |
| DataHub Demo | Metadata management, data discovery, and data platforms |
| PyArmor Demo | Python application protection and deployment |
| MCP vs API Demo | MCP and traditional API integration patterns |
| OTEL Demo | Distributed tracing, observability, and incident investigation |
Reusable engineering tools designed to extend beyond a single workshop.
- MailingKit - A provider-agnostic Python email layer with a consistent API.
Focused, reusable instructions and workflows for AI-assisted development.
- JARS Skills - Practical agent skills and engineering playbooks for modern coding tools.
- Learn by doing. Working code over theory alone.
- Reproducible by design. Clear setup instructions and verifiable results.
- Understand the trade-offs. Explore limitations, failure modes, and implementation choices.
- Independent by default. Each project maintains its own scope, dependencies, and lifecycle.
- Open to collaboration. Contributions, feedback, and thoughtful experimentation are welcome.
Choose a project, follow its setup instructions, experiment with the implementation, and explore the underlying technology.
