PRD Hub — Decentralized Product Specs on Nostr

Vision

In the vibe coding era, the PRD is the real source code. AI can regenerate implementations from a good spec — so the spec is what matters. PRD Hub gives product specs a permanent, censorship-resistant home on Nostr.

No platform lock-in. No walled gardens. Your product vision, signed with your keys, living on a decentralized protocol.

Problem

Product specs live in Google Docs, Notion, or Linear — all centralized, all ephemeral
No public marketplace to discover, share, or remix product ideas
AI coding tools (Cursor, Claude Code, Copilot) need structured specs as input, but there's no standard place to find them
Builders can't easily monetize or get credit for great product thinking

Solution

A Nostr-native hub for Product Requirements Documents that supports:

Publishing — Write PRDs in markdown, publish as NIP-23 (kind:30023) long-form content with a t:prd tag
Forking — Fork any PRD to remix it, with attribution back to the original via a tags
Zapping — Support great specs with sats via NIP-57 lightning zaps
Discovery — Browse and filter PRDs by tags, find specs for any domain
Ownership — Every PRD is signed with your Nostr keypair. It's yours.

How It Maps to Nostr

Each PRD is a kind:30023 event with:

Field	Usage
`d` tag	Unique slug (e.g., `saas-invoicing-app`)
`t` tags	`prd` (required) + custom tags
`title` tag	PRD title
`summary` tag	Short description
`content`	Full PRD in markdown
`a` tag	Reference to original PRD (for forks)

Design Direction

Cypherpunk / security aesthetic:

Dark theme (#0a0a0a) with muted greens and cyans
Monospace typography (JetBrains Mono) for headers and code
Terminal-style UI elements (command prompts, blinking cursors)
Sharp corners, no bubbly rounded elements
Subtle grid background + noise texture
Glowing accents on hover states
Lightning bolt iconography for zaps

Future Ideas

AI integration — "Generate codebase from this PRD" button that sends the spec to an AI coding tool
Commenting — NIP-based threaded comments on PRDs
Versioning — Track PRD revisions over time
Collections — Curated lists of related PRDs
Bounties — Attach sats bounties to PRDs for builders who implement them
Export — Download PRDs as PDF or feed them directly to Claude/GPT

Success Metrics

Number of PRDs published
Fork ratio (forks / original PRDs)
Total sats zapped
Unique authors publishing
Returning users (session persistence)

Built with Nostr. The protocol is the platform.
