Instead of sending your users to a separate LMS portal, you generate a course, embed it where they already work, and get every completion sent back to your own systems. How it works Create a course.

Features and specs

What each product offers, as listed by its team.

Vite 6 features

  • Fast Development Server
    Vite uses native ES Modules and leverages browser support for them, which allows for an extremely fast development startup time.
  • Hot Module Replacement (HMR)
    Vite supports fast Hot Module Replacement (HMR), which allows developers to see changes almost instantly without reloading the entire application.
  • Optimized Build
    Vite has a built-in build command that bundles your code with Rollup, providing out-of-the-box optimizations for production.
  • Plugin Ecosystem
    Vite has a rich plugin ecosystem and allows for easy integration with various plugins for different functionalities such as TypeScript, JSX, and more.
  • Framework Agnostic
    Vite is not tied to any specific framework and can be used with Vue, React, Preact, Svelte, and others, making it very versatile.
  • TypeScript Support
    Vite supports TypeScript out-of-the-box, making it easier for developers to work with type-safe code.

Possible disadvantages

  • Ecosystem Maturity
    As a relatively new tool, Vite's ecosystem is not as mature as those of more established bundlers like Webpack, which might lack some advanced features.
  • Plugin Compatibility
    Some existing plugins or tools that work with Webpack or other bundlers may not be directly compatible with Vite, requiring additional setup or alternative solutions.
  • Limited Community Support
    Given its newness, the community around Vite is smaller compared to older tools. This can make finding help or resources more challenging for complex issues.
  • Learning Curve
    Developers familiar with more traditional setups like Webpack might face a learning curve in adapting to Vite’s methodology and features.

Questions & Answers

As answered by people managing Vite 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.
