Makers-first
We build for creators and developers who ship. No enterprise bloat, no feature theatre. Every decision starts with: does this help someone publish faster?
About us
Built by one founder who was
fed up with clunky social tools.
PostSider started as an internal tool I built to automate social media for my own projects. It worked so well I decided to build it properly and make it available to everyone.
Our mission
Publishing superpowers for everyone.
We believe every creator, brand and developer should have the same publishing superpowers as a full social media team. That means a calendar that doesn't fight you, an API that developers actually want to use, and an agent bridge that lets AI do the heavy lifting.

Encrypted tokens
Our values
What we stand for.
Privacy & Security
Your OAuth tokens are encrypted at rest with AES-256-GCM. We never read your content unless you explicitly grant access. Security is engineered in, not bolted on.
Open by default
Full REST API, MCP server, and open SDKs. PostSider is a platform, not a walled garden. Build on top of it, automate it, extend it. We actively encourage it.
The maker
One person. Big ambitions.
PostSider is designed, built and run by one person. That means no bloat and no committees, just a product shaped by a single clear vision: tools that care about developer experience, design quality, and getting out of your way.
