The Verdict
Publer has the real free plan here: free forever for up to 3 social accounts (except X), 10 scheduled posts per account and 25 drafts, something PostFast doesn't offer at any price.
But Publer's paid pricing is per account, so the bill scales linearly as you connect more accounts, and its REST API is gated to Enterprise, Business-in-good-standing and Top Ambassador users; its own MCP server, shipped in beta in late August 2026, is gated further still, to Top Ambassadors and Enterprise only.
PostFast has no free plan, only a 7-day trial, but its flat per-workspace pricing includes full API and MCP access from the €12 Starter tier, and a fixed account allowance per tier rather than a per-account meter.
Choose PostFast if
- +Teams with several accounts where flat per-workspace pricing beats a per-account meter
- +Developers wanting full API and MCP access on the cheapest paid plan
- +Agencies wanting white-label branding and dozens of workspaces in one plan
- +Workflows built around comment management included free at every tier
Choose Publer if
- +Solo creators or small brands with 1-3 accounts wanting to stay free
- +Anyone who wants AI prompts, competitor analysis and best-times-to-post in one tool
- +Budget-conscious users who'd rather pay per account than commit to a tier
- +Teams fine with API access starting at a mid tier rather than the entry plan
Pricing
Which one costs more?
Publer prices per connected social account (its pricing page uses a quantity selector, and the headline figures below are for one account); PostFast prices per workspace tier with a fixed account allowance. These are also two different currencies, EUR for PostFast and USD for Publer, so treat this as directional rather than a converted total.
The practical effect: Publer gets cheaper per account only in absolute terms at very low account counts, while PostFast's flat tiers stop scaling with account count until you cross into the next tier's ceiling.

| Plan / Tier | PostFast | Publer | Notes |
|---|---|---|---|
| Free | None (7-day trial, no card, full features) | Free forever: 3 accounts (except X), 10 scheduled posts/account, 25 drafts, 1 workspace | Publer's Free plan never expires. PostFast has no permanent free tier. |
| Entry paid | Starter: €12/mo, or €10/mo billed annually, flat for 4 accounts | Professional: $5/mo per account, or $4/mo per account billed yearly | Publer's Professional price is per account: 4 accounts on Professional costs roughly 4x the per-account rate, while PostFast's Starter is one flat price for up to 4 accounts. |
| API / automation tier | Full API and MCP included from Starter (€12/mo) | Business: $10/mo per account, or $8/mo per account billed yearly, the cheapest Publer tier with API access | Publer's REST API is available to Enterprise clients, Business subscribers in good standing, and Top Ambassadors. Its MCP server is a separate beta, limited to Top Ambassadors and Enterprise only, so Business alone does not unlock it. PostFast includes both API and MCP on its entry tier. |
| Team / scale | Growth: €49/mo, or €40/mo billed annually (30 accounts, 10 workspaces, 8 users/workspace) | Business tier scales per account with no published flat team tier | PostFast bundles team seats and workspaces into the flat price; Publer's team costs scale per account plus separate per-member charges per our data. |
| Agency / white-label | Pro (Agency): €99/mo, or €82.50/mo billed annually (120 accounts, white-label, 30 workspaces) | Enterprise: custom pricing, billed yearly | Publer's Enterprise tier is quote-only; no published price to compare directly. |
| Top tier | Enterprise: €239/mo, or €199/mo billed annually (500 accounts) | Enterprise: custom pricing | Both top out in custom/enterprise territory; only PostFast publishes a number for it. |
Buddy's Take on Pricing
There's no single winner here, the two pricing models serve different buyers. If you only need a few accounts and want to start free, Publer wins outright: nothing PostFast offers is free forever.
Once you're paying for API access and multiple accounts, run the numbers: Publer's Business tier is $10/mo per account (so scales linearly with account count), while PostFast's €12 Starter is a flat price for up to 4 accounts with API and MCP already included.
The crossover point depends on your account count and whether you need Publer's Business-tier extras (AI prompts, competitor analysis, best-times-to-post).

Features
Capability comparison
Line these two up and the split tracks the pricing model: Publer front-loads value into a real free plan and gates automation and AI extras behind its Business tier; PostFast has no free plan but puts API, MCP and comment management on its cheapest paid tier.

The MCP story changed recently and is worth being precise about. PostFast's server is an official, open-source project it maintains, documented at 24 tools over stdio (26 through its hosted connector), spanning publishing, analytics, follower history and Social Inbox. Publer shipped its own official MCP server in late August 2026, connecting Claude and ChatGPT to a workspace, but it is currently in beta and restricted to Top Ambassadors and Enterprise clients, not open to Business-tier subscribers.
If an AI agent connecting to your scheduler is the point today, PostFast's entry tier gets you there now; Publer's path exists but is not generally available yet.
Publer's Business tier is genuinely feature-dense: unlimited AI prompts, competitor analysis, best-times-to-post and hashtag analytics all land there, none of which PostFast currently ships. If those features matter more to you than agent-native API access, Publer's Business tier at $10/mo per account is worth pricing against your account count directly.
Comment management is the one clear structural gap. PostFast's Social Inbox is included free at every tier, including the 7-day trial. We didn't find an equivalent unified inbox in Publer's published plans; its comment-related feature is 'Schedule 1st comments & threads,' which is about posting a first comment automatically, not triaging incoming replies.

Who It's For
Who should choose which?
Choose PostFast if you...
- +You want full API and MCP access on your cheapest paid plan, not gated to a higher tier
- +You manage enough accounts, or enough team seats, that a flat per-workspace price beats a per-account meter
- +You want agency features (white-label, 30+ workspaces) bundled into one plan
- +You don't need a permanent free plan and are fine with a 7-day trial
Choose Publer if you...
- +You only need 1-3 social accounts and want to stay on a free plan indefinitely
- +You want AI writing prompts, competitor analysis and best-times-to-post baked in (Publer's Business tier)
- +Your account count is small enough that per-account pricing beats a flat tier
- +You're fine with API access starting at a higher tier ($10/mo Business) rather than the entry plan
Final recommendation
The bottom line
If your account count is small (1-3) and you want to start at zero cost, Publer's Free plan is the more generous starting point, full stop. If you're going to pay either way and want full API and MCP access on the cheapest tier plus a comment inbox that never costs extra, PostFast's flat €12 Starter plan is the more predictable buy as your account count grows.
If AI writing prompts and competitor analysis matter more than agent-native automation, Publer's Business tier earns its $10/mo per account. Price out your actual account count on both before deciding; the per-account vs per-workspace-tier gap is the whole story here.
FAQ
Frequently Asked Questions
It depends entirely on account count. Publer is free forever for up to 3 accounts, and its Professional tier is $4-5/mo per account. PostFast has no free plan but its €12 Starter is a flat price covering up to 4 accounts. Do the math for your specific account count since the two price on different axes.
Yes, now. Publer shipped its own official, first-party MCP server in late August 2026, connecting Claude and ChatGPT to your workspace from Settings. It is currently in beta, though, and limited to Top Ambassadors and Enterprise clients, so a regular Business-tier subscriber cannot turn it on yet. PostFast's MCP server is official and open source, documented at 24 tools over stdio (26 through its hosted connector), and available on every plan including the trial.
No. Publer's REST API is available to Enterprise clients, Business subscribers in good standing, and Top Ambassadors ($10/mo per account, or $8/mo billed yearly, for Business). Its MCP server is a separate, narrower beta: even on Business, MCP itself is limited to Top Ambassadors and Enterprise clients only. PostFast includes full API and MCP access on its €12 Starter plan.
Publer, today. Its Business tier includes unlimited AI prompts, competitor analysis, best-times-to-post and hashtag analytics. PostFast has no shipped AI Assistant; one is on its roadmap with scope under review.
