About Bat and Underlayer

In their own words, as submitted to SaaSHub.

Underlayer

No description of Bat 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.

Bat 6 features
Underlayer 0 features
  • Syntax Highlighting
    Bat provides syntax highlighting using the same syntax definitions as Sublime Text, which makes it easier to read code and configuration files compared to plain `cat`.
  • Git Integration
    Displays Git modifications alongside code, showing added, removed, and changed lines, which helps in tracking changes directly within the file contents.
  • Line Numbering
    Automatically includes line numbers in the output, which can be very useful for referencing specific lines without additional commands or tools.
  • Paging Support
    Integrates with paging utilities like `less` by default, allowing users to scroll through large files smoothly.
  • Compatibility
    Designed to be a drop-in replacement for `cat`, meaning it can be used in scripts and interactively without significant changes.
  • File Concatenation
    Like `cat`, Bat can concatenate files, streaming their content in a readable format with added enhancements.

Possible disadvantages

  • Installation Requirement
    Unlike `cat`, which is pre-installed on most Unix systems, Bat may require manual installation, adding an extra step before use.
  • Performance Impact
    The additional features like syntax highlighting and Git integration may cause a slight delay compared to the instantaneous output of `cat`, especially for very large files.
  • Dependency on External Tools
    Relies on other tools, like `less`, for full functionality, which may not be available in minimal environments.
  • Complexity for Simple Tasks
    For users who need to quickly view file contents without any enhancements, Bat's additional features may be overkill.
  • Resource Usage
    Consumes more system resources like memory and CPU compared to `cat`, particularly noticeable when dealing with very large files or using extensive syntax highlighting.

Questions & Answers

As answered by people managing Bat 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.
