Questions & Answers

As answered by people managing Obsidian and PostSider.

What makes your product unique?

PostSider's answer:

PostSider combines traditional social media management with developer and AI-agent infrastructure. You can manage, schedule, review and publish content across 30+ platforms from a visual dashboard, while the same publishing infrastructure is accessible through REST API, a TypeScript SDK and MCP. This means humans, scripts, applications and AI agents can work with the same social media workflow.

How would you describe the primary audience of your product?

PostSider's answer:

PostSider is built for content creators, solo founders, startups, marketing teams, agencies and developers who publish content across multiple platforms. It is especially useful for users who want to automate social media workflows

Why should a person choose your product over its competitors?

PostSider's answer:

PostSider is a strong fit for creators, founders, teams and developers who want to manage many social channels without paying separately for every integration. It offers flat-tier pricing, 30+ supported platforms, scheduling, approvals, analytics, queues and per-platform content variants. Every plan also includes API and agent access, making PostSider useful for both manual workflows and advanced automation.

What's the story behind your product?

PostSider's answer:

PostSider started as a tool I wanted for my own projects. Managing multiple social platforms meant switching between dashboards, dealing with different APIs and repeating the same publishing work over and over.

I wanted one bridge that both I and my automation tools could use to manage social media from a single place. As AI agents became more capable, the idea evolved further: instead of building only another scheduler, I started building a publishing layer that can be used by humans, developers and AI agents alike.

PostSider is built and operated by me, Łukasz Blania, as a solo founder in Poland.

Which are the primary technologies used for building your product?

PostSider's answer:

PostSider is primarily built with TypeScript and web technologies. Its developer platform includes a REST API, an official TypeScript/Node.js SDK, webhooks and a Model Context Protocol (MCP) server for AI-agent integrations. PostSider also integrates directly with the APIs and authentication systems of supported social networks.
