SocialBu is a $29-a-month social media scheduler built around automation rules and a shared inbox, and its pricing page hides a cap most buyers never think to check: a 750-post-a-month ceiling on top of the 8-account limit, both on the same Starter tier. Hit either number and the plan stops working until you upgrade, which is exactly why anyone scheduling in bulk, or running several active accounts at once, starts looking for a SocialBu alternative.
What SocialBu costs in 2026
Checked directly against SocialBu's own pricing page in November 2026, the plan structure runs four tiers: a limited free plan, then Starter, Growth, and Agency.
| Plan | Price | Accounts | Posts/month | AI credits |
|---|---|---|---|---|
| Free | $0/mo | 3 | 10 lifetime | 60 |
| Starter | $29/mo ($22/mo yearly) | 8 | 750 | 500 |
| Growth | $79/mo ($59/mo yearly) | 20 | 3,000 | 2,000 |
| Agency | $199/mo ($149/mo yearly) | 50 | Unlimited | 10,000 |
The free tier is the sharpest limit on the page: 10 lifetime posts, not 10 a month. Once those are used, the account can't schedule anything else without upgrading. Starter removes that lifetime wall but replaces it with a monthly one, 750 posts, which only disappears entirely on the $199/month Agency plan.
Why a post cap matters more than an account cap
An account cap is a one-time decision: you know how many brands or clients you manage, so you pick a tier and that number rarely moves mid-month. A monthly post cap behaves differently, because it resets the moment you most need headroom. Running a product launch week, batching a month of content in one sitting, or picking up a new client partway through a billing cycle can all push past 750 scheduled posts before the plan's own cap even notices there's a problem, and the fix is the same either way: upgrade to Growth at $79/month, nearly triple the Starter price, for a cap that's still there at 3,000.
What SocialBu's AI credits actually cover
Starter includes 500 AI credits a month, used for caption generation and the platform's automation rules (auto-replies, keyword-triggered actions). That's a separate allowance from the post cap, so a heavy automation user can burn through credits well before touching the 750-post ceiling, while a bulk scheduler hits the post cap first and barely touches the AI allowance. The two limits move independently, which makes it easy to assume you have headroom on one axis while actually running out on the other.
Who actually needs a SocialBu alternative
SocialBu's Starter plan works fine for a single creator or small brand posting a modest, steady cadence across a handful of accounts. It stops working the moment any of these is true:
- You bulk-schedule a month or a quarter of content in one sitting, which can burn through 750 posts fast if you manage more than one or two accounts.
- You run more than 8 connected accounts, which means paying for Growth or Agency regardless of how light your actual posting volume is.
- You want a flat monthly price with no separate ceiling on how many posts you're allowed to queue.
- You're testing the free plan and discover the 10-post cap is lifetime, not monthly, and already used up.
SocialBu vs a cross-posting-first alternative
Synapse takes the opposite approach to limits: plans cap connected accounts, the same axis most flat-rate schedulers use, but never cap how many posts you schedule in a month. It's built as a cross-posting tool first, reaching nine platforms from one composer rather than gating volume behind a second counter.
| Plan | Price | Accounts | Posts/month cap | Platforms |
|---|---|---|---|---|
| SocialBu Starter | $29/mo | 8 | 750 | Not advertised as 9-platform |
| SocialBu Growth | $79/mo | 20 | 3,000 | Not advertised as 9-platform |
| Synapse Starter | $7/mo | 5 | None | 9 (incl. X, YouTube, Threads, Bluesky) |
| Synapse Creator | $19/mo | 15 | None | 9 |
At less than a quarter of SocialBu's Starter price, Synapse's own Starter plan drops the monthly post ceiling entirely and still connects all nine major platforms. SocialBu's edge is its built-in automation rules and shared inbox for teams; Synapse's edge is posting volume with nothing counting against you except the account count you've already paid for.
How much does SocialBu cost per month?
SocialBu's paid tiers in November 2026 are Starter at $29/month ($22/month billed yearly), Growth at $79/month, and Agency at $199/month, each verified directly against SocialBu's pricing page. A free plan is also available with reduced limits.
Does SocialBu limit how many posts I can schedule?
Yes. Starter caps scheduling at 750 posts a month, Growth at 3,000, and only Agency ($199/month) removes the cap entirely. The free plan's limit is stricter still: 10 posts total, not per month.
How many accounts can SocialBu connect?
Starter connects 8 accounts, Growth 20, and Agency 50, all on SocialBu's own pricing page as of November 2026. Needing more than 50 accounts means a custom plan.
What happens if I hit SocialBu's post cap mid-month?
Scheduling stops working on the current plan until the cap resets the next billing cycle or the account upgrades to a higher tier with a larger (or no) cap.
Is there a SocialBu alternative with no monthly post limit?
Synapse's Starter plan is $7/month for 5 accounts across all nine major platforms with no monthly cap on scheduled posts, and it bundles its own AI caption credits at no extra cost.
Can I move my scheduled posts off SocialBu to another tool?
Not automatically. Switching schedulers means reconnecting each social account on the new tool and re-entering anything still sitting in SocialBu's queue by hand, since no scheduler can pull another tool's pending posts directly. Timing the switch for a near-empty queue, right after a batch has gone out, makes the move far less tedious.
