Quick Comparison

Prices in this guide are per month with yearly billing unless marked monthly.

Pricing Breakdown

Buffer Pricing

Buffer charges per channel:

• Free: up to 3 channels, 10 scheduled posts per channel
• Essentials: from $5/mo per channel billed yearly, $6 monthly
• Team: from $10/mo per channel billed yearly, $12 monthly

Buffer's strength is its simplicity. If you manage a small number of channels, the cost stays low. The per-channel model still grows with every account you add, though Buffer charges less for each channel above 10 (on Team, $4 instead of $12 per channel on monthly billing), so 20 channels come to $160/month.

Sendible Pricing

Sendible is designed for agencies and offers tiered plans, each with unlimited users:

• Core: $30/mo billed yearly, $35 monthly (1 workspace, 6 profiles)
• Plus: $84/mo billed yearly, $99 monthly (3 workspaces, 18 profiles)
• Premium: $169/mo billed yearly, $199 monthly (7 workspaces, 42 profiles)
• Elite: $254/mo billed yearly, $299 monthly (15 workspaces, 90 profiles)
• Enterprise: $638/mo billed yearly, $750 monthly (50 workspaces, 300 profiles)

Sendible offers a 14-day free trial. Their agency focus shows in features like custom branded reports (Premium and above), a paid white-label add-on (Elite and Enterprise), and a priority inbox for managing social conversations. Sendible is a strong choice for agencies that need polished client-facing reports and branded experiences.

PostFast Pricing

PostFast uses flat monthly pricing:

• Starter: €10/mo billed yearly, €12 monthly (4 accounts, 1 user)
• Creator: €24/mo billed yearly, €29 monthly (12 accounts, 5 users per workspace)
• Growth: €40/mo billed yearly, €49 monthly (30 accounts, 8 users per workspace)
• Pro: €82.50/mo billed yearly, €99 monthly (120 accounts, 15 users per workspace)
• Enterprise: €199/mo billed yearly, €239 monthly (500 accounts, 30 users per workspace)

PostFast includes approval workflows on every plan, and on Pro and Enterprise your client PDF reports can carry the client's logo and name with PostFast branding switched off. The 7-day free trial gives you access to the complete feature set.

The Pricing Math

All prices in this section are per month with yearly billing.

Managing 12 social accounts with 2 users:

For the same 12 accounts, PostFast costs a third of Sendible Plus in the same currency (€24 against €72 when Sendible bills in euros) and well under Buffer's $107/mo. Sendible can also add 6-profile workspace bundles to a smaller plan; its pricing page does not list the bundle price.

At 25 accounts with 4 users:

PostFast Growth covers 30 accounts for €40/mo, while 25 profiles take Sendible past Plus (18 profiles) to Premium.

At 50 accounts with 7 users:

Even at scale, PostFast stays well below both alternatives. The Growth plan at €40/mo covers 30 accounts for growing teams, and the Pro plan gives you 120 accounts for €82.50/mo, more headroom than Sendible's Elite plan (90 profiles), which costs €234/mo when billed in euros.

Feature Comparison

Scheduling and Publishing

All three platforms handle multi-platform scheduling and publishing. Buffer keeps the interface minimal and focused. Sendible adds content suggestions, RSS feeds, and a smart compose box that tailors posts for each platform. PostFast supports scheduling across 11 platforms (Facebook, Instagram, TikTok, X, LinkedIn, YouTube, Threads, Pinterest, Bluesky, Telegram, and Google Business Profile) with a visual calendar.

Approval Workflows

PostFast includes approval workflows on all plans, including Starter at €10/mo. Buffer restricts approvals to the Team plan ($10/channel). Sendible includes approvals from the Plus plan ($84/mo).

If team sign-off matters to your workflow, PostFast gives you this feature at the lowest cost.

Agency and White-Label Features

This is where Sendible shines. Custom branded reports start on Premium ($169/mo), and Elite and Enterprise can add white labelling for an extra fee, which puts all your clients into one branded space (Sendible's pricing FAQ quotes white-label pricing from $349/month on Elite). Sendible has built its reputation on helping agencies look professional in front of clients.

PostFast's white-label is limited to reports: on Pro (€82.50/mo) and Enterprise, the client PDF report carries your client's logo and name with PostFast branding switched off. There is no custom domain or rebranded login, so if you need clients inside a branded dashboard, Sendible's add-on is built for that. If branded reports are enough, PostFast is the more affordable path.

Buffer's Team plan adds branded reports with your logo and a cover page; its pricing page lists no white-label option.

Social Inbox and Engagement

Sendible includes a priority inbox that aggregates messages, comments, and mentions across platforms. This is valuable for agencies managing community engagement for multiple clients. Buffer has basic engagement features. PostFast's Social Inbox covers comments on TikTok, Instagram, Facebook and Threads posts and is included on every plan, including the 7-day trial. It handles comments only, so Sendible is the broader choice if you need messages and mentions in the same queue.

Analytics and Reporting

Sendible offers detailed analytics with exportable reports that agencies can share with clients. The reports can be customized and branded on higher-tier plans. Buffer provides straightforward post-performance analytics. PostFast includes engagement tracking and performance data for TikTok, Instagram, Facebook, Threads, YouTube, LinkedIn Pages and Pinterest business accounts.

Platform Support

Buffer supports 12 platforms, making it the widest in raw platform count, and it is the only one of the three with Mastodon and Substack. PostFast supports 11 platforms, including Bluesky, Google Business Profile and Telegram, and it is the only one of the three with Telegram. Sendible supports 9 platforms with strong integrations for the core networks plus Google Business Profile and Bluesky.

FAQ

Is Sendible good for small teams?

Sendible's Core plan at $30/mo (billed yearly) gives you 6 profiles in 1 workspace with unlimited users, which works for small teams managing a single brand. However, if you need more than 6 profiles, you either add workspace bundles of 6 profiles or move to Plus at $84/mo. PostFast's Creator plan offers 12 accounts at €24/mo, also billed yearly, giving you double the profiles at a comparable price point.

Can Buffer handle agency workloads?

Buffer can technically manage many channels, but its per-channel pricing makes it expensive at agency scale. There is no white-label option, and branded reports come only with the Team plan. Buffer is better suited for individual creators or small marketing teams than for client-facing agency work.

Does PostFast have client reporting like Sendible?

PostFast provides post-level analytics and engagement data for TikTok, Instagram, Facebook, Threads, YouTube, LinkedIn Pages and Pinterest. On Pro and Enterprise, the client PDF report carries your client's logo and name with PostFast branding switched off. It brands the report, not a dashboard on your own domain.

Which tool supports the most social platforms?

Buffer supports 12 platforms, PostFast supports 11 (including Bluesky, Google Business Profile and Telegram), and Sendible supports 9. All three cover the major platforms like Facebook, Instagram, X, LinkedIn, and TikTok. The differences are in niche platform support: Buffer is the only one of the three with Mastodon and Substack, and PostFast is the only one with Telegram.

Can I switch from Sendible or Buffer to PostFast?

Yes. PostFast supports all major social platforms, so you can connect your existing accounts and begin scheduling immediately. The 7-day free trial lets you test the full feature set, including approval workflows and the Social Inbox, before making the switch.
