  WhatsApp MCP Server2025 · github.com · ▲229

The MCP server can: - Search your messages, contacts, and groups - Send WhatsApp messages to…

  A journaling service that runs over WhatsApp2024 · todayhasbeen.com · ▲126

  Hey Hacker News, I’m excited to share a tiny service that’s very close to my heart - Today Has Been. Here’s how it works: We have a phone number that has WhatsApp Business API enabled.

  I built a frontpage for personal blogs▲783

  With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
