PostKeno vs Buffer — Do You Need a Dedicated Approval Tool?

Buffer is a well-known name in the social media tools space. PostKeno is a dedicated content approval platform built specifically for marketing agencies. This comparison examines how they differ in pricing, features, and suitability for agency content approval workflows in 2026.

Quick overview

PostKeno is purpose-built for the content approval workflow between agencies and their clients. It focuses on making that specific step — client reviews content, leaves feedback, approves — as fast and frictionless as possible. Buffer takes a different approach as a social media scheduling tool. The question is not which tool is better overall, but which is better for the specific job of client content approval.

Pricing comparison

PostKeno is significantly more affordable than Buffer for the specific job of content approval. The pricing difference is substantial for agencies managing multiple clients, where tool costs need to scale efficiently. For a broader view, see our full comparison of content approval tools in 2026.

Feature comparison

Scheduling tool vs approval platform: different categories

Buffer and PostKeno are not direct competitors — they solve different problems. Buffer is a social media scheduling tool: you write a post, queue it, and Buffer publishes it at the right time. PostKeno is a content approval platform: the agency creates content, the client reviews and approves it, and then the approved content is scheduled for publication.

The confusion arises because agencies sometimes use Buffer's draft-sharing feature as an improvised approval workflow. But Buffer was not designed for this. There is no structured feedback system, no pin comments, no approval status tracking, no automatic reminders, and no client-facing review interface. Using Buffer for approval is like using a spreadsheet for project management — it works until it does not.

Multilingual support

Buffer's interface is English only. PostKeno supports six European languages. But more importantly, PostKeno provides a dedicated client-facing review interface that Buffer simply does not have. The language support is the cherry on top of a fundamentally different product category.

Who wins and when

Choose PostKeno if:

• You need a structured approval workflow between your agency and clients
• Client feedback and revision management are important to your process
• You want visual feedback features (pin comments, video timestamps)
• You need multilingual support for European clients
• You want automatic reminders for pending approvals

Choose Buffer if:

• You are a solo creator who needs simple scheduling
• You do not need client approval — you publish your own content
• You need a free scheduling tool for basic social media management
• Your workflow does not involve external client review

FAQ

Can Buffer be used for content approval?

Buffer is a scheduling tool, not an approval platform. While you can share drafts, Buffer lacks structured approval workflows, client-facing review interfaces, pin comments on images, video timestamp comments, automatic reminders, and version history. For agencies that need client approval, a dedicated tool like PostKeno is recommended.

Do I need both Buffer and PostKeno?

Many agencies use PostKeno for client approval and a separate scheduling tool for publishing. PostKeno provides ZIP downloads of approved content (images, captions, hashtags) that can be uploaded to any scheduling tool. The two tools complement each other rather than compete.

Which is cheaper?

Buffer has a free plan for basic scheduling. PostKeno starts from €9/month for content approval. They solve different problems at different price points — comparing them on price alone misses the point.
