More than 30 networks, including X, Instagram, TikTok, YouTube, LinkedIn, Facebook, Pinterest, Discord, Telegram, Mastodon, Bluesky and many more. New ones are added regularly.

PostSider exposes scheduling, publishing and analytics through a Model Context Protocol (MCP) server. Connect Claude, Codex, Cursor or any MCP agent in one step, or call the REST API and SDKs directly.

Yes. Channel tokens are encrypted with AES-256-GCM, requests are hardened against SSRF and CSRF, and access is rate-limited and isolated per channel with least privilege.

Absolutely. Connect your channels, rebuild your queues in the calendar, and you are publishing in minutes. The same setup works for both your team and your agents.

A 7-day trial of the full product: calendar, composer, the agent bridge and the API. No credit card required to start.

Yes. Plans are month to month and you can upgrade, downgrade or cancel whenever you like.

PostSider uses flat tiers, not per-channel billing: $20 per month covers 5 channels, $35 covers 10 with unlimited team members. Adding another network costs nothing until you cross a tier, which is usually cheaper than per-channel pricing beyond 4 channels.

Connect your channels to PostSider in parallel (this does not affect your old tool), rebuild your posting slots, then bring your queue over manually or via CSV import. Run both tools for one overlap week, then cancel the old one.

One person: Lukasz Blania, a solo founder building PostSider from Poland under Lumi Zone. Support emails land with the person who wrote the code.

PostSider ships an AI post checker and per-network caption rewrite. Use the built-in AI or bring your own OpenAI API key. There is no auto-generated content spam: the AI checks and refines what you or your agent drafted.
