Possible disadvantages

  • Steep Learning Curve
    Due to its extensive features and capabilities, Unreal Engine can be challenging for beginners to master, requiring a significant investment of time and effort to learn.
  • High System Requirements
    Developing with Unreal Engine often requires a powerful computer with strong hardware specifications, which can be a barrier for developers with limited resources.
  • Large File Sizes
    Unreal Engine projects can result in large file sizes, which can be cumbersome to manage, particularly in terms of storage and transfer bandwidth.
  • Complexity for Simple Projects
    For smaller or simpler projects, the capabilities of Unreal Engine might be overkill, and using it can unnecessarily complicate development when compared to lighter engines.
  • Royalty Fees
    Unreal Engine imposes a royalty fee of 5% on gross revenue after the first $1 million USD per product per year, which can impact the profitability of commercial projects.
  • Less C++ Flexibility
    While Unreal Engine supports C++, the engine imposes certain constraints and abstractions that can limit the flexibility developers might need for highly customized or optimized code.

Questions & Answers

As answered by people managing Unreal Engine and Underlayer.

Who are some of the biggest customers of your product?

Underlayer's answer:

it's pre-launching

What makes your product unique?

Underlayer's answer:

Underlayer is training with no portal. You build a course by API, by MCP, or in the visual builder, and add it to your product with one iframe. Then signed webhooks tell your systems who finished. Learners never create an account or leave your app, and the player uses your theme, so it looks like part of your product. We charge per course view, not per seat, and every price and overage rate is published.

Why should a person choose your product over its competitors?

Underlayer's answer:

Most course tools, like Coassemble, Trainn and LearningStudioAI, assume training happens on their own site: learners sign up, log in and get enrolled, and you pay per seat. Underlayer takes the opposite approach:

No learner accounts. You pass in your own user IDs and we track progress against them. Built for developers. A full REST API covers every resource, and an MCP server lets AI agents create and edit courses. Results in your own tools. Signed webhooks send completions to your CRM, your product or your data warehouse. SCORM 1.2 and 2004 export for customers who still need to load courses into an LMS. Public pricing. Plans start at $149/month for 25,000 course views, with unlimited learners and no sales call required.

How would you describe the primary audience of your product?

Underlayer's answer:

SaaS product, customer success and engineering teams who want onboarding, product education or compliance training inside their own app. It also suits platforms that train other people's users, like partner networks, marketplaces and field-ops tools, where a separate LMS login gets in the way.

What's the story behind your product?

Underlayer's answer:

Every company putting training in front of its users hit the same wall: the LMS wanted to own the learner. That meant a separate portal, a second login and a per-seat bill for people who never opened a course. We built Underlayer as the layer underneath instead. You keep the product and the user relationship. We handle building the course, playing it and tracking progress, and we stay out of the way.

Which are the primary technologies used for building your product?

Underlayer's answer:

Next.js 16 (App Router) with React 19 and TypeScript, Tailwind CSS v4, and Supabase (Postgres with row-level security, Auth and Storage). Claude from Anthropic generates courses with AI. Stripe handles billing and Resend sends email. There is also a remote MCP server with OAuth 2.1 for AI-agent access.
