What LateWiz is
LateWiz is a free, open-source social media scheduling tool available on the web or through self-hosting. Its visual calendar presents scheduled content in one place, while Smart Queue lets users define posting times and have posts scheduled automatically. Image and video uploads are supported up to 5GB. Listed networks include Instagram, TikTok, YouTube, LinkedIn, Pinterest, X, Facebook, Threads, Bluesky, Snapchat, Google Business, Reddit, Telegram, Discord, and Slack. LateWiz is built on the Zernio API, so connecting social accounts requires a Zernio API key. The maker says OAuth authentication is handled through Zernio and that LateWiz does not store social media credentials. For self-hosting, users can clone the repository, add the key, and deploy on Vercel, Netlify, or their own server. The project is MIT licensed and described as free to use. Its Free plan costs nothing, with no per-plan limits stated.
