Buffer vs Sprout Social vs PostFast: Which Scheduler Fits Your Budget?

Choosing a social media scheduler usually comes down to two things: what it can do and what it costs. Buffer, Sprout Social, and PostFast sit at very different points on that spectrum. One targets enterprises with deep analytics, another keeps things simple for small teams, and the third delivers professional features without the professional price tag.

This comparison breaks down pricing, features, and platform support so you can pick the tool that actually fits your workflow and your budget.

Quick Overview

Buffer is the approachable middle ground. It offers a free tier for individuals and scales per channel, making it easy to start but potentially expensive as you add accounts. It covers 11 platforms and keeps the interface clean and focused on publishing.

Sprout Social is the enterprise heavyweight. Starting at $199 per seat per month, it bundles social listening, CRM features, and detailed analytics dashboards. If you need competitor analysis, sentiment tracking, and executive-level reporting, Sprout delivers. But you pay for it.

PostFast is built for creators and agencies who need scale without the markup. Flat monthly pricing covers multiple accounts, with plans from EUR 12 to EUR 99 per month. The new Growth plan at EUR 49 per month covers 30 accounts. Every plan includes API access, video transcoding, and support for 10 platforms including Telegram and Bluesky.

Feature Comparison

Platform Support

Buffer and PostFast both support Bluesky, while Sprout Social does not. PostFast is the only tool here with Telegram support. Buffer uniquely covers Mastodon, and Sprout Social includes Snapchat.

Pricing Breakdown

This is where the differences become dramatic. Buffer charges per channel, Sprout Social charges per seat, and PostFast uses flat monthly plans.

At small scale, Buffer's free tier is hard to beat. But once you cross 10 accounts, PostFast's flat pricing pulls ahead significantly. Sprout Social remains the most expensive option at every tier, though it includes analytics and listening features the others do not.

The cost gap widens as you scale. At 25 accounts, PostFast's Growth plan is EUR 49 per month vs Buffer at $250 and Sprout Social at $597. At 50 accounts, PostFast's Pro plan covers up to 120 accounts for EUR 99 per month vs Buffer at $500 and Sprout Social at $995.

Analytics and Reporting

Sprout Social is the clear leader in analytics. Its reporting suite includes cross-network performance reports, competitor benchmarking, paid campaign tracking, and custom report builders. For teams that need to present data to stakeholders or clients, Sprout's polished PDF exports and scheduled reports are a genuine differentiator.

Buffer provides engagement metrics, post performance data, and audience growth tracking. It is clean and functional but lacks the depth of Sprout's reporting. The analytics are sufficient for creators and small teams who want to know what is working without drowning in dashboards.

PostFast offers standard analytics covering post performance and engagement. While it does not match Sprout's enterprise-grade reporting, PostFast compensates with API access on every plan, letting teams pull data into their own dashboards or reporting tools.

Collaboration and Workflows

Sprout Social was built for teams. It includes approval workflows, task assignment, a shared content calendar, and role-based permissions. If your social media operation involves multiple stakeholders who need to review content before it goes live, Sprout handles that natively.

Buffer added team features with its Team plan at $10 per channel per month. You get draft collaboration and approval flows, but the per-channel pricing compounds quickly for larger teams.

PostFast focuses on efficient publishing rather than multi-layer approval chains. For solo creators and small teams who do not need formal sign-off processes, this keeps the workflow fast. Agencies managing client accounts benefit from the Pro plan's white-label option and the ability to manage up to 120 accounts under one subscription.

Content Creation and Publishing

All three tools handle core scheduling and cross-posting. The differences show up in the extras.

Buffer's AI Assistant helps generate post ideas and repurpose content. Its interface is deliberately minimal, making it quick to learn and use daily.

Sprout Social includes an asset library, message tagging, and content categorization. Its publishing calendar is feature-rich and supports bulk scheduling via CSV.

PostFast includes video transcoding, which automatically optimizes video for each platform's requirements. CSV bulk import lets you schedule dozens of posts at once. The OpenClaw AI integration adds AI-powered content assistance, and API access on all plans means you can build custom publishing workflows.
