If you're comparing Post Planner alternatives, check the tier structure before the sticker price. Post Planner's $14/mo Starter plan doesn't include X (Twitter) or Pinterest at all; posting to either one requires the $59/mo Growth plan, a jump of more than four times the price. That single gate is why so many Post Planner alternative roundups default straight to a flat, per-account tool instead. Post Planner itself is built around a different job than most schedulers: finding and recycling other people's viral content, not just publishing your own.
This guide breaks down what actually changes at each Post Planner tier, where a flat per-account scheduler costs less for straightforward cross-posting, and where Post Planner's own strength, content discovery, still has no real substitute. See our broader all-in-one social media scheduler guide for how the wider category stacks up if you haven't narrowed it down to Post Planner specifically yet.
What to check before you pick a Post Planner alternative
Post Planner runs seven tiers, from a free plan up to a 200-account agency bundle at $629/mo (verified directly at postplanner.com/pricing, Oct 2026). The free and Starter plans are priced around the product's original strength, a Reddit and RSS-powered content-discovery feed for finding and recycling viral posts, not around posting breadth. Three things change as you move up the tiers, and none of them are obvious from the pricing page's headline numbers alone.
- Platform access. X and Pinterest publishing is locked out entirely on Free and Starter; both unlock only at Growth ($59/mo) or above.
- Content-curation age. Free can only surface viral posts from the last 7 days; Starter extends that to 30 days. Anything older needs a paid Content Premium add-on.
- Seats and volume. Starter allows one user and 150 scheduled posts total; Growth moves to two users and 1,500 posts; only Business ($99/mo) and above go unlimited.
If you're evaluating Post Planner specifically to post to X or Pinterest, the plan that actually unlocks either one is priced three tiers up from the entry plan, not the $14/mo sticker price most comparison pages lead with. The same jump applies to team size: a second teammate forces Growth too, since Starter is capped at one user regardless of account count, so a two-person team paying for X and Pinterest access is really paying for both gates at once.
Post Planner's pricing, tier by tier, against a flat-rate option
Here's how Post Planner's three most relevant tiers compare with Synapse's own plans, which price by connected-account count rather than gating specific platforms behind a higher tier (cross-checked directly against `src/lib/entitlements.ts`).
| Plan | Monthly price | Accounts | X + Pinterest included | Team seats |
|---|---|---|---|---|
| Post Planner Starter | $14/mo ($9/mo annual) | 3 | No | 1 |
| Post Planner Growth | $59/mo ($39/mo annual) | 15 | Yes | 2 |
| Post Planner Business | $99/mo ($69/mo annual) | 25 | Yes | 5 |
| Synapse Starter | $7/mo ($77/yr) | 5 | Yes | 1 |
| Synapse Creator | $19/mo ($209/yr) | 15 | Yes | 1 |
| Synapse Growth | $39/mo ($429/yr) | 50 | Yes | 5 |
At 15 connected accounts, Post Planner's Growth tier, the two paths cost $59/mo and $19/mo respectively, and both include X and Pinterest. The $40/mo gap is the price of Post Planner's content-discovery engine; if you don't use it, you're paying for it anyway once you need Growth just to reach X and Pinterest. Stretch to 25 accounts and the comparison holds the same shape: Post Planner's Business tier runs $99/mo for 25 accounts and five seats, while Synapse's Growth plan covers up to 50 accounts and five seats for $39/mo, less than half the price for double the account headroom, because Synapse isn't also billing for a discovery feed layered on top of scheduling.
Annual billing narrows the headline numbers without closing the gap. Post Planner's Growth tier drops to $39/mo paid yearly ($468/yr total), matching Synapse's Growth monthly list price, but that rate still only covers 15 accounts and 2 seats. Synapse's own annual rate for the same tier is $429/yr, about $35.75/mo, for up to 50 accounts and 5 seats, a larger allowance at a lower effective monthly price either way you pay.
What Post Planner does that a flat-rate scheduler doesn't
Post Planner's real differentiator isn't scheduling, it's discovery. The platform surfaces trending and evergreen posts pulled from Reddit and RSS feeds that you can recycle into your own queue indefinitely, a feature none of the straightforward cross-posting tools, Synapse included, try to replicate. If your content calendar depends on curating other people's posts rather than publishing your own, that's a real reason to stay on Post Planner rather than switch.
Where Post Planner's tiers get expensive is the moment you want to post your own content everywhere, including X and Pinterest, without a content-discovery engine attached. That's the gap a flat per-account scheduler fills: every Synapse plan, including the $7/mo Starter tier, connects all nine platforms Synapse supports (X, LinkedIn, Bluesky, YouTube, Pinterest, Facebook, Instagram, Threads, and TikTok), with the account count, not the platform list, as the only thing that changes between tiers.
Who should actually switch
A Post Planner Starter or Free subscriber who only needs X and Pinterest, without the content-discovery feed, is paying for a tier structure built around a feature they aren't using. Someone who relies on Post Planner's Reddit and RSS recycling day to day is better served staying put: no comparison tool here, Synapse included, replicates that workflow.
Buffer and RecurPost take different approaches to the same price-by-account-count idea; see our Buffer alternative and RecurPost alternative comparisons if per-seat or per-platform fees are the sticking point with either of those instead. If you do decide to switch, move your content calendar over deliberately rather than all at once; our guide on switching schedulers without losing your queue covers the actual steps.
Either way, the decision usually comes down to one question: is the content-discovery feed doing real work in your week, or have you been scheduling your own posts and letting that part of the plan sit unused? If it's the second, the $40-plus monthly gap at comparable account counts is money spent on a feature you never open.
Frequently asked questions
What is the cheapest Post Planner alternative that includes X and Pinterest?
Synapse's $7/mo Starter plan includes X and Pinterest from day one, for up to 5 connected accounts. Post Planner doesn't unlock either platform until its $59/mo Growth plan.
Does Post Planner support posting to X (Twitter) and Pinterest?
Only on Growth ($59/mo monthly, $39/mo billed annually) or above. Post Planner's Free and Starter plans exclude both platforms entirely.
How many social accounts does Post Planner's Starter plan allow?
Three, for $14/mo ($9/mo billed annually). Synapse's $7/mo Starter plan allows five accounts, including X and Pinterest, at a lower monthly price.
Is there a free Post Planner alternative?
Post Planner's own Free plan covers one account and 30 scheduled posts, with curated content limited to items 7 days old or newer. Synapse has no permanently free tier, but every plan, including Starter, opens with a 7-day free trial, card required.
What does Post Planner do that a flat-rate scheduler doesn't?
Its Reddit and RSS-powered content-discovery feed, which surfaces viral and evergreen posts you can recycle into your own queue indefinitely. No straightforward cross-posting tool, Synapse included, replicates that feature today.
Can I switch away from Post Planner without losing my content calendar?
Yes, if you move it over deliberately: export or rebuild your queue before canceling, rather than letting an annual plan lapse mid-transition. See our guide on switching schedulers without losing your queue for the specific steps.
