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

Operating in show hn launch, Open-Source Inbox-as-a-Service for LLM Agents operates.

Profile

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,

Its activity falls under show hn launch; the profile below is assembled from public directory data.

The company is listed at the Show HN launch stage of development.
