Hey everyone, I built Postiner, a social media scheduler designed for social media managers handling multiple projects.

My first collaborator shaped many of the features, and working with them showed me how valuable real collaboration is in building something people actually need. They pushed me to open it up to others, and now I'm looking for new collaborators.

What we've built so far (more at https://postiner.com/#features):

- Dark and light mode (this was a dealbreaker)

- Two posting modes: broadcast the same content across accounts, or customize individually per account—with easy switching between both, real-time platform validation, clear error messages, post priorities, and more

- Drafts and workspace organization for managing multiple projects (teams coming soon)

- AI-powered tools (via MCP)

- Automatic thread support for Threads, Twitter/X, and Bluesky

- Recurring posts, bulk actions, first comment scheduling (on supported platforms), carousels, and more

- Campaign grouping for easier analytics and post management, with PDF and CSV export

- More goodies inside
