Underlayer is headless, API-first training for SaaS products. 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.

pacaur 4 features
Underlayer 0 features
  • AUR Support
    Pacaur provides seamless integration with the Arch User Repository (AUR), allowing users to easily access and install a wide variety of user-submitted packages.
  • Dependency Management
    Pacaur automatically handles dependencies for AUR packages, ensuring that all necessary components are installed without user intervention.
  • User-Friendly Interface
    Pacaur offers a user-friendly interface that simplifies package management, making it easier to search, install, and manage packages.
  • Automation of Tasks
    Pacaur automates many routine tasks such as updates and installations, reducing the time and effort required from the user.

Possible disadvantages

  • Maintenance Status
    As of its last updates, Pacaur is no longer actively maintained, which may lead to compatibility issues with newer systems and limits future improvements or bug fixes.
  • Complexity for New Users
    Although it offers advanced features, Pacaur can be complex for new Arch users who are unfamiliar with terminal-based package management tools.
  • Potential for Breakage
    Being an AUR helper means Pacaur installs unsupported packages which might sometimes conflict with official packages, potentially causing system instability.
  • Dependency on AUR
    Pacaur relies heavily on the AUR, which can be unreliable at times due to user-submitted content, including potentially outdated or unmaintained packages.

Questions & Answers

As answered by people managing pacaur 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.
