Pricing Breakdown

Buffer Pricing

Buffer charges per channel:

• Free — 3 channels, 10 scheduled posts per channel
• Essentials — $5/mo per channel (annual billing)
• Team — $10/mo per channel (annual billing)

Buffer's strength is its simplicity. If you manage a small number of channels, the cost stays low. But the per-channel model means costs scale linearly — 20 channels on Team costs $200/month with no volume discount.

Sendible Pricing

Sendible is designed for agencies and offers tiered plans:

• Creator — $29/mo (6 profiles, 1 user)
• Traction — $89/mo (24 profiles, 4 users)
• Scale — $199/mo (49 profiles, 7 users)
• Advanced — $299/mo (100 profiles, 20 users)

Sendible offers a 14-day free trial. Their agency focus shows in features like white-label dashboards (Scale plan and above), client reporting, and 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 — €12/mo (4 accounts, 1 user)
• Creator — €29/mo (12 accounts, 2 users)
• Pro — €99/mo (120 accounts, 10 users)
• Enterprise — €239/mo (500 accounts, unlimited users)

PostFast includes approval workflows on every plan and white-label starting at Pro. The 7-day free trial gives you access to the complete feature set.

The Pricing Math

Managing 12 social accounts with 2 users:

PostFast costs roughly 75% less than Buffer and 67% less than Sendible for the same number of accounts.

At 50 accounts with 7 users:

Even at scale, PostFast stays well below both alternatives. And the Pro plan gives you 120 accounts — more headroom than Sendible's Advanced plan at triple the price.

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 10 platforms (Facebook, Instagram, TikTok, X, LinkedIn, YouTube, Threads, Pinterest, Bluesky, and Telegram) with a visual calendar.

Approval Workflows

PostFast includes approval workflows on all plans, including Starter at €12/mo. Buffer restricts approvals to the Team plan ($10/channel). Sendible includes approval workflows on all paid plans.

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. Their Scale ($199/mo) and Advanced ($299/mo) plans include white-label dashboards, custom branding, and detailed client reports. Sendible has built its reputation on helping agencies look professional in front of clients.

PostFast offers white-label on the Pro plan at €99/mo — less than half the cost of Sendible's Scale plan. If you need white-label without the full agency reporting suite, PostFast is the more affordable path.

Buffer does not offer any white-label capabilities.

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 focuses primarily on scheduling and publishing rather than inbox management.

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 across all connected platforms.

Platform Support

Buffer supports 11 platforms, making it the widest in raw platform count. PostFast supports 10 platforms including Bluesky and Telegram, which are not available on many competitors. Sendible supports 9 platforms with strong integrations for the core networks plus Google Business Profile.

FAQ

Is Sendible good for small teams?

Sendible's Creator plan at $29/mo gives you 6 profiles and 1 user, which works for small teams managing a single brand. However, if you need more than 6 profiles, the jump to $89/mo is significant. PostFast's Creator plan offers 12 accounts at €29/mo, 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 are no white-label options and client reporting is basic. 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 across all platforms. While it does not have Sendible's branded client report exports, it offers white-label on the Pro plan so agencies can present a branded dashboard to clients at a much lower cost.

Which tool supports the most social platforms?

Buffer supports 11 platforms, PostFast supports 10 (including Bluesky 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 — PostFast is the only one of the three with native Bluesky and Telegram support.

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 white-label, before making the switch.
