Social Media Management
PostSider
PostSider is a social publishing calendar built for both people and their automations. A creator can draft, queue, and schedule in the dashboard; an AI assistant or script can use the same publishing workflow through MCP, REST, or an SDK. Its September 21, 2026 Product Hunt launch reached #13 with 90 points. That is a modest launch-day interest signal, not a product review or proof of reliable publishing across every network.
The reason to consider another scheduler is the shared human-and-agent workflow. PostSider advertises 30-plus destinations and flat channel-count tiers instead of billing for every connected account. For a three-channel solo creator who only clicks “schedule,” Buffer's free plan may be enough. PostSider becomes more relevant if your own scripts or an assistant prepare posts but you still want a calendar, queue, and approvals. The site names solo founder Lukasz Blania and publishes its plans; this profile is based on those public materials rather than hands-on publishing tests.

Pricing
Read from PostSider's pricing section on September 27, 2026 (verify current). There is a 7-day trial without a credit card, but no listed permanent free plan. Standard is $20/month for one seat, five channels, and 400 posts per month. Team is $35/month for 10 channels, unlimited posts and team members, plus approvals and the AI post checker. Pro is $45/month for 30 channels and extra bulk and webhook features. Ultimate is $90/month for 100 channels and agency-oriented controls.
Every published tier lists the agent bridge and API. The channel cap still matters: “flat pricing” means a fixed tier until you cross its channel allowance, not unlimited connected accounts. The vendor says plans are month to month and can be cancelled. Confirm the platforms and specific publishing actions you need in the trial, since network permissions and API policies can change independently of PostSider.
Pros and cons
Pros
- Human calendar and automation use the same scheduled-post workflow.
- Transparent monthly tiers make a five- or ten-channel budget easy to compare.
- API and MCP access do not require a separate enterprise plan.
Cons
- No permanent free plan; Buffer is cheaper for very small, manual schedules.
- Its published documentation says there is no unified social inbox, so comment and message management need another tool.
- It is a young solo-founder product with a lower Product Hunt launch rank and limited long-term evidence; verify delivery on each network you use.
Who should use PostSider?
PostSider fits a creator or small agency that already automates drafts or campaigns and wants an orderly way to review and schedule them. It is also worth comparing when you run five or more channels and per-channel competitor pricing grows. If all you need is three social accounts and a simple queue, start with Buffer. If inbox and listening are central, compare Hootsuite or another broader platform.
The September launch gives a discovery point, not a reliability verdict. Use the trial to connect your real channel mix, schedule test posts, check approval behavior, and confirm what analytics return.
