New open-source project: LateWiz 🪄
Built an open-source social media scheduler on top of the Late SDK in ~4 hours using Claude Code.
What it does:
1. Plug in your Late API key
2. Get a dashboard to post and connect accounts
3. That's it
Why this matters for you:
→ Fork it, extend it, make it yours
→ Reference implementation for Late SDK
→ See how little code you actually need
Check it out: https://latewiz.com
