Underlayer

No description of Standard JS yet.

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.

Standard JS 4 features
Underlayer 0 features
  • Zero Configuration
    Standard JS comes with a set of rules and configurations out of the box. This eliminates the need to set up a linting configuration file, saving developers time and reducing the cognitive load associated with decision-making.
  • Uniformity
    By enforcing a consistent style across projects, Standard JS helps to create a uniform codebase. This makes it easier for teams to read and understand each other's code, reducing onboarding time for new developers.
  • Community and Support
    As a popular style guide and linter, Standard JS has a robust community and extensive documentation. This support makes it easier for developers to find solutions to issues and to integrate Standard JS into their projects.
  • Less Distraction
    With pre-set rules, developers spend less time debating over coding styles and more time focusing on actual code logic and building functionality.

Possible disadvantages

  • Limited Customization
    Since Standard JS comes with a predefined set of rules, it offers limited flexibility for customization. Developers who prefer tailor-made configurations might find it restrictive.
  • Opinionated Rules
    Standard JS follows an opinionated approach to styling, which might not align with certain team or individual preferences. Some developers might find specific enforced styles disagreeable.
  • Compatibility Issues
    In some cases, Standard JS rules might conflict with pre-existing project configurations or other linters in the project, possibly causing friction during integration.
  • Learning Curve
    For developers new to Standard JS, there may be a learning curve as they acclimate to its specific rules and enforcement practices, particularly if they're used to other style guides.

Questions & Answers

As answered by people managing Standard JS 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.
