Quick Overview

Buffer offers a free tier with 3 channels and 10 scheduled posts each. Paid plans run $5 per channel per month on Essentials or $10 per channel per month on Team. It supports 11 platforms, has a clean interface, and includes an AI Assistant for content generation.

PostFast uses flat monthly pricing. The Starter plan is EUR 12 per month for 4 accounts. Creator is EUR 29 per month for 12 accounts. Pro is EUR 99 per month for 120 accounts. Every plan includes API access, video transcoding, and CSV bulk import. A 7-day free trial is available with no credit card required.

Feature Comparison

Buffer includes several extras like a landing page builder, link shortener, and Start Page for creating a link-in-bio page. These are nice additions for creators who want an all-in-one toolkit.

PostFast focuses on core scheduling power: video transcoding, API access, CSV bulk import, and white-label on Pro. These are features that matter most when you are managing content at scale or building integrations.

Platform Support

Both tools cover the 8 core platforms plus Bluesky. PostFast adds Telegram, which Buffer does not support. Buffer adds Mastodon and Google Business, which PostFast does not support.

For most users, the overlap covers everything they need. The decision comes down to specific platforms: if you need Telegram, PostFast is your pick. If you need Mastodon or Google Business, Buffer is the choice.

Pricing: The Full Picture

This is where the comparison gets interesting. Buffer's per-channel model is simple to understand but compounds quickly. PostFast's flat plans stay predictable.

At 3 accounts, Buffer's free tier wins outright. You pay nothing versus EUR 12 per month for PostFast.

At 5 accounts, the gap narrows. Buffer Essentials costs $25 per month, PostFast Creator costs EUR 29 per month. Roughly equivalent.

At 10 accounts, PostFast pulls ahead. Buffer Essentials hits $50 per month while PostFast Creator stays at EUR 29 per month.

At 20 accounts, the gap is significant. Buffer Essentials costs $100 per month. PostFast Pro costs EUR 99 per month but covers up to 120 accounts, so you have massive headroom.

At 50 accounts, the difference is dramatic. Buffer at $250 to $500 per month versus PostFast at EUR 99 per month. That is 2.5 to 5 times the cost for the same number of accounts.

At 100 accounts, Buffer would cost $500 to $1,000 per month. PostFast Pro still costs EUR 99 per month with room for 20 more accounts.

Where Buffer Wins

Free tier. If you manage 3 or fewer channels and can work within the 10 scheduled posts limit per channel, Buffer costs nothing. PostFast has no free tier, only a 7-day trial.

Simplicity. Buffer's interface is intentionally minimal. The learning curve is nearly flat. You can be scheduling posts within minutes of signing up.

Mastodon and Google Business. If either of these platforms is part of your strategy, Buffer supports them and PostFast does not.

Extra tools. Buffer's landing page builder, Start Page (link-in-bio), and link shortener add value for creators who want fewer separate tools.

AI Assistant. Buffer's built-in AI helps generate post copy, repurpose content, and brainstorm ideas directly in the composer.

Brand maturity. Buffer has operated since 2010 with millions of users. For teams justifying a tool purchase to management, Buffer's name recognition carries weight.

Where PostFast Wins

Price at scale. Once you manage more than 5 accounts, PostFast's flat pricing becomes increasingly advantageous. At 50 accounts, you could save $150 to $400 per month compared to Buffer.

API access on all plans. PostFast includes API access from the EUR 12 Starter plan up. Buffer does not offer public API access. If you want to build automations or integrate scheduling into custom workflows, PostFast is the only option here.

Video transcoding. PostFast automatically transcodes video files for each platform's format and size requirements. This saves time and eliminates manual conversion steps.

Telegram support. PostFast is one of the few schedulers that supports Telegram as a publishing channel.

CSV bulk import. Need to schedule 50 posts at once from a spreadsheet? PostFast handles batch scheduling via CSV. Buffer does not offer this.

White-label. PostFast's Pro plan includes white-label capabilities for agencies. Buffer does not offer white-labeling.

No per-channel math. PostFast plans include a set number of accounts at a flat price. The pricing is predictable as you scale.

Frequently Asked Questions

Is Buffer really free?

Buffer offers a free plan that covers 3 channels with up to 10 scheduled posts per channel. There are no time limits on the free tier. However, the 10-post queue limit per channel is restrictive for anyone posting daily. Upgrading to Essentials at $5 per channel removes the queue limit.

Does PostFast have a free plan?

PostFast does not have a permanent free tier. It offers a 7-day free trial with full access to all features, and no credit card is required to start. After the trial, the Starter plan begins at EUR 12 per month.

Can I switch from Buffer to PostFast easily?

PostFast supports CSV import, so you can export your content calendar and re-import it. Social account connections need to be set up fresh since OAuth tokens cannot transfer between platforms. The process is straightforward but requires reconnecting each account.

Which tool is better for video content?

PostFast wins on video. Its built-in video transcoding automatically optimizes video files for each platform's specifications, handling format conversion, resolution adjustments, and file size limits. Buffer supports video uploads but does not transcode, meaning you need to prepare platform-specific video files yourself.

Is PostFast's API useful for non-developers?

The API is primarily a developer tool, but it unlocks automation for anyone using no-code platforms. You can connect PostFast to Make.com, n8n, or Zapier to automate content scheduling from spreadsheets or AI content generators. On Buffer, this is not possible since there is no public scheduling API.
