Social Magnum vs Post Bridge: Two Agent-Era Schedulers (2026)
The closest matchup in this series: both flat-priced, both MCP-connected, five dollars apart. Their network list runs wider, our operating layer runs deeper — both pages priced the same day.
This is the closest matchup in our whole comparison series. Post Bridge and Social Magnum are both agent-era schedulers: flat-priced, MCP-connected, built for creators and small teams rather than enterprises. The prices sit five dollars apart. What separates them is scope on each side — their network list runs wider, our operating layer runs deeper — so this page is mostly a map of those two edges.
Pricing side by side
| Post Bridge | Social Magnum | |
|---|---|---|
| Entry plan | Creator: $29 /mo · 15 accounts · unlimited posts | Starter: $24 /mo ($19 yearly) · 10 accounts · 2 people |
| Mid plan | Growth: $49 · 50 accounts · team invitations | Business: $59 ($47) · 30 accounts · 6 people |
| Top plan | Pro: $99 · unlimited accounts | Agency: $119 ($95) · 70 accounts · 10 people |
| Free tier | 5 posts /mo | 2 accounts · 15 posts /mo |
| Trial and guarantee | 7-day free trial | 14-day money-back guarantee |
| Per-account at entry | $1.93 per account if you fill all 15 | $2.40 per account at 10 — cheaper outright at 10 or fewer |
Both rows are honest: filled to capacity, Post Bridge’s entry plan is the better per-account rate; at ten accounts or fewer, ours costs less in absolute dollars and includes a second seat.

Where Post Bridge wins
- The network list. X, LinkedIn and Google Business in the base price — three networks we do not publish to, with no add-on fees.
- Accounts per dollar at capacity. 15 accounts at $29, 50 at $49, unlimited at $99 — generous counts at every tier for solo operators running many profiles.
- Creator-shaped extras. Bulk video scheduling and a content studio aimed squarely at short-form volume posting.
Where Social Magnum wins
- The operating layer. A unified inbox with keyword auto-replies, post approvals and RSS automation — none of which appear on Post Bridge’s site.
- A teammate at entry. 2 people at $24; Post Bridge holds team invitations until $49.
- Unmetered AI in the plan. Captions and images generated without a counter; mature analytics rather than a beta.
- The deeper agent surface. Both products speak MCP — ours documents 26 tools publicly with OAuth, approval gates and pacing rules; judge both by their docs.
Which one to pick
The short version
- 1
Solo creator posting volume across X, LinkedIn and the visual networks: Post Bridge — 15 accounts at $29 with MCP is a strong deal.
- 2
A two-person team that answers comments and needs approvals: Social Magnum — the operating layer is the difference, at $5 less.
- 3
Mastodon in the roster: us; X, LinkedIn or Google Business: them.
- 4
AI agents matter to you: both connect over MCP — read each vendor's agent docs against your workflow before deciding.
- 5
Cheapest honest test: our free plan (2 accounts, 15 posts) against theirs (5 posts) — run the same week through both.
