PostKeno vs Gain — Content Approval Tools Comparison

Gain is one of the most well-known content approval tools in the English-speaking market, largely because of its free tier which made it accessible to agencies testing the concept of structured approval workflows. PostKeno is a European-focused alternative with a broader feature set and a more aggressive pricing model. This comparison breaks down where each tool excels and where it falls short for marketing agencies. For a broader comparison, see our full comparison of content approval tools in 2026.

Quick overview

Gain positions itself as a pure content approval platform with a focus on automating the feedback and sign-off process. Its free tier attracted many small agencies, though the free plan has significant limitations. PostKeno covers the same core functionality but adds multilingual support, visual feedback features, and a lower entry price for paid plans.

Pricing comparison

The pricing difference is dramatic. PostKeno starts at €9/month while Gain's paid plan starts at 99 USD/month — more than ten times the cost. Even accounting for Gain's free tier, agencies that outgrow the free plan face a steep jump. PostKeno's 30-day free trial gives agencies enough time to test the full feature set before committing.

Feature comparison

Visual feedback: PostKeno's differentiator

Gain focuses on text-based comments for content review. PostKeno goes further with pin comments on images — clients click on the exact part of the image they want changed and leave a note anchored to that location. For video content, clients can leave comments tied to specific timestamps. These features eliminate the ambiguity that causes unnecessary revision cycles.

For agencies handling high volumes of visual content (which is most social media agencies), this distinction is the single most impactful feature difference between the two tools. Vague feedback like "change the image" becomes precise, actionable feedback pinned to the exact element in question.

Multilingual support

Gain's interface is English only. PostKeno supports six European languages: Polish, English, German, French, Spanish, and Italian. For agencies with non-English-speaking clients, this is a dealbreaker. When a German client logs into PostKeno, they see the entire interface in German. When they log into Gain, everything is in English — creating friction that slows down every approval cycle. Learn more about managing multilingual clients.

Who wins and when

Choose PostKeno if:

• You need multilingual support for European clients
• Visual feedback on images is important for your workflow
• You manage YouTube content that needs client approval
• You want predictable pricing without a steep jump from free to paid
• Budget efficiency matters — €9/mo vs 99 USD/mo is a significant difference

Choose Gain if:

• You need a free plan and your volume is within the free tier limits
• All your clients are English-speaking
• You do not need visual feedback features (pin comments, video timestamps)
• You are already established on Gain and switching cost is a concern

Workflow comparison

Both tools support the core approval workflow: agency uploads content, client reviews, client approves or requests changes. The key differences are in the details of how feedback is collected and how the revision cycle is managed.

PostKeno supports a full revision cycle with version history. When the client requests changes, the agency uploads a new version, and both old and new versions are visible side by side. The client can compare exactly what changed. Gain supports revisions but without the same visual version comparison capability.

PostKeno also offers an optional internal review step: before the client sees the content, a manager or creative director reviews it internally. This catches errors before they reach the client, which is especially valuable for agencies with junior team members or high content volumes. Gain does not have a built-in internal review stage.

Platform support

PostKeno supports Instagram, Facebook, TikTok, LinkedIn, and YouTube. Gain supports Instagram, Facebook, TikTok, and LinkedIn but not YouTube. For agencies that manage video content across platforms, the absence of YouTube support in Gain means maintaining a separate approval workflow for YouTube content, which fragments the process and increases the chance of errors.

As short-form video continues to dominate social media strategy in 2026, YouTube Shorts has become an integral part of many agencies content mix. Managing YouTube approval outside the main tool undermines the efficiency that a centralised approval platform is supposed to provide.

FAQ

Is Gain really free?

Gain offers a free tier, but it has significant limitations on the number of workspaces and features available. Most agencies outgrow the free plan within a few months. The jump to Gain's paid plan (99 USD/month) is steep. PostKeno's 30-day free trial with no feature restrictions offers a different approach — test everything, then pay €9/month to continue.

Which tool has better customer support?

PostKeno offers priority support on Growth and Agency plans. Gain provides email support on all plans. For agencies where approval delays directly impact client relationships, response time matters. Both tools have knowledge bases and documentation available.

Can I migrate from Gain to PostKeno?

Yes. Since both tools manage content approval workflows, migration involves setting up your clients and team in PostKeno and redirecting your approval process. There is no data migration needed — you start fresh with new content submissions. Most agencies complete the switch within one week.
