What LateWiz is

LateWiz is a free, open-source social media scheduling tool available on the web or through self-hosting. Its visual calendar displays scheduled content, while Smart Queue lets users set posting times once and have posts scheduled automatically. Image and video uploads can be 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 authentication runs through Zernio using OAuth and that LateWiz does not store social media credentials. For self-hosting, users can clone the repository, add a Zernio API key, and deploy on Vercel, Netlify, or their own server. LateWiz is MIT licensed and described as free to use. Its Free plan costs nothing, with no per-plan limits stated.

Who it suits

LateWiz suits individuals, teams, and operators scheduling content across many social networks. Self-hosting also suits users who want to deploy the MIT-licensed project themselves.
