Yay 5 features

Underlayer 0 features

AUR Support
Yay provides seamless support for Arch User Repository (AUR) packages, allowing users to easily search for, install, and update AUR packages along with official repository packages.
Combined Package Management
It combines both AUR and official repository package management in one tool, streamlining the process and reducing the need to use multiple package managers.
User-Friendly Interface
Yay offers a user-friendly command-line interface with clear prompts and options, making it easier to navigate and use than some other AUR helpers.
Speed and Efficiency
Thanks to its optimized codebase and use of go programming language, Yay is typically faster than some alternatives, enhancing the overall system update process.
Interactive Search
It provides an interactive search feature, allowing users to conveniently search for packages without leaving the terminal interface, enhancing user experience.

Possible disadvantages

Dependency Management Complexity
Managing dependencies for AUR packages can become complex and may require manual intervention, particularly with packages that have many dependencies or conflicts.
Potential for Inexperienced User Errors
As with any AUR helper, misuse by inexperienced users could potentially lead to system instability if non-vetted or conflicting packages are installed.
Security Risks
Since AUR packages are user-submitted, there is an inherent security risk involved with installing them, as they may not receive the same scrutiny as official repository packages.
Limited Official Support
While Yay is popular and widely used, it is not officially supported by Arch Linux, and users must turn to community forums for support and troubleshooting.
Dependency on the Go Language
As Yay is written in Go, it requires Go runtime for compilation from source, which might be an inconvenience for some users who prefer not to have additional language runtimes.

Questions & Answers

As answered by people managing Yay 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.
