Frequently asked questions
Common questions when comparing Onepostly with Postiz.
Postiz cloud enforces a strict 100 requests per hour rate limit while self hosting requires you to maintain OAuth apps and queues for dozens of platforms. Onepostly is fully managed with high throughput and native MCP support.
Self hosting means you must register and maintain developer accounts on every social platform, handle token refresh crons, fix breaking changes when APIs update, and manage database queues yourself. Onepostly handles all of that automatically.
Postiz cloud locks you into plans like $29 for 5 channels and $49 for 30 channels. Onepostly gives you 1 account free forever then $5 and $3 and $1 per account as you grow.
