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

rnc000 — Tue, 21 Apr 2026 19:06:25 +0000

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.

Show HN: Rakenne – Markdown-defined agentic workflows for structured documents

rnc000 — Mon, 16 Feb 2026 12:26:31 +0000

Hi! I’m the creator of Rakenne and I built it because I noticed a recurring problem with LLMs in professional settings: chat-based document creation is unpredictable and hard to scale for domain experts.

Experts know the process of building a document (the questions to ask, the order of operations, the edge cases), but translating that into a long system prompt often leads to hallucinations or missed steps.

What is Rakenne? Rakenne is a multi-tenant SaaS that lets domain experts define "Guided Workflows" in Markdown. An LLM agent then runs these workflows server-side, conducting a structured dialogue with the user to produce a final, high-fidelity document.

The Tech Stack:

* Agentic Core: Built on the pi coding agent (https://github.com/badlogic/pi-mono) using RPC mode. This allows the agent to maintain state and follow complex logic branches defined in the Markdown files.

* Frontend: Built with Lit web components. I wanted something incredibly lightweight and framework-agnostic so the document "interviews" feel snappy and can eventually be embedded as widgets.

* Multi-tenancy: Designed to isolate agent environments server-side, ensuring that custom expert logic doesn't leak between tenants.

Why this approach? Instead of "Chat with a PDF," it’s "The Logic of an Expert." If you’re a lawyer or a compliance officer, you don’t want a creative partner; you want a system that follows your proven methodology. By using Markdown, we make the "expert logic" version-controllable and easy for non-devs to edit.

I’d love your feedback on:

1. The Agentic UX: Does the "interview" flow feel natural, or is it too rigid? 2. Markdown as Logic: Is Markdown the right "DSL" for this, or should we move toward something like YAML or a custom schema? 3. Latency: We're using RPC for the agent-browser communication—is the response time acceptable for your use case?

Thanks! I'll be around to answer any technical questions.

Show HN: Open-Source Inbox-as-a-Service for LLM Agents

rnc000 — Thu, 12 Feb 2026 14:35:54 +0000

If you’re building agents that need to read and send email, you’ve probably hit the limits of typical email APIs: they’re stateless, focused on sending, and don’t give you threads, history, or content that’s easy for an LLM to use. NornWeave is an open-source, self-hosted Inbox-as-a-Service API built for that use case. It adds a stateful layer (virtual inboxes, threads, full history) and an intelligent layer (HTML→Markdown parsing, threading, optional semantic search) so your agents can consume email via REST or MCP instead of raw webhooks and HTML.

You get virtual inboxes per agent, webhook ingestion from SMTP/IMAP, Mailgun, SES, SendGrid, or Resend, and an MCP server that plugs into Claude, Cursor, and other MCP clients with tools like create_inbox, send_email, search_email, and wait_for_reply. Threads are returned in an LLM-friendly format (e.g. role/author/content), and you can self-host on your own infra. If your agents need to own an inbox and hold context across messages, NornWeave is worth a look.

how's traction going? Do you worry about some open-source project replacing it?

Good point. But still, it's hard to believe that it's taking years for Google to add to GAE a mature Search API and support for multiple datacenter locations, which are things Google does better than anyone.

What are Google's long-term plans for Google App Engine?

rnc000 — Sat, 22 Dec 2012 19:03:06 +0000

GAE as a platform is really great (good scalability, no maintenance overhead, low latency in most cases) but the extremely slow pace (compared to Amazon Web Services) for introducing new APIs and maturing the existing (ex.: increasing quotas and charging for the Search API, Prospective Search) makes me wonder: is Google really investing enough engineers to mature its platform? Will it pull the plug and stop offering it? Is the Premier support option really helpful? What are it's long-term plans? Where's the roadmap? These are very important questions considering it's PaaS and you'll be deeply committed to it "by design" once you Go Google.

Is there a market for content-based image search SaaS?

rnc000 — Tue, 09 Dec 2008 01:43:10 +0000

I've been thinking about providing the opensource content-based image database at http://server.imgseek.net/ as a hosted service. This would allow image-related websites to provide visual query-by-example and query-by-sketch features with minimal setup effort. Can you see demand for it?

call me skeptic but I can't envision MoinMoin+trac being used as a large scale CMS system (which means a deployment into a corporation, which means some corporate suit not "buying IBM" and risking losing his job)
