Show HN: Rikdom – Open-source, local-first wealth portfolio schema toolkit

Designed so your portfolio data can last for years as plain JSON files, independent of any broker app or SaaS dashboard. With coding agents and LLMs, it is much easier to build your own asset management software and adapt it to your needs over time. rikdom focuses on the durable layer beneath that iteration: a solid foundation for storing and evolving financial data, plus a plugin system you can extend with coding agents and enrich with reusable open-source plugins.
