Obsidian ↔ Linear Sync Plugin

Elevator pitch

Bidirectional sync between Obsidian notes and Linear issues. Free tier = one-way Linear → Obsidian pull. Pro tier = full bidirectional sync with conflict resolution.

Why this product

• I am the target customer (Linear + Obsidian user, daily driver).
• No good existing plugin covers this pair — closest is a dormant one-way Linear → Notion bridge.
• Obsidian community discovers and shares plugins aggressively (2M+ users via the official community-plugins repo).
• No backend required → low ops overhead for the portfolio.

Architecture (summary)

• Runtime: Obsidian plugin (TypeScript, compiled with esbuild) running client-side on user's machine.
• Auth: User supplies a Linear personal API key in plugin settings. Stored in Obsidian's config (local machine only).
• Linear client: Typed GraphQL client with exponential-backoff retry on rate limits and DataLoader-style batching.
• Content conversion: Bidirectional Markdown ↔ Linear ProseMirror JSON converter with unit tests covering code blocks, nested lists, mentions, and attachments.
• Sync engine: Pull every N minutes + manual trigger. Push on debounced file save. Last-write-wins conflict resolution with a user prompt on divergence >24h.
• License: HMAC-signed license keys, validated offline. Stripe Payment Link → Cloudflare Worker webhook → license email.
