Features and specs

What each product offers, as listed by its team.

hastebin 5 features
Underlayer 0 features
  • Ease of Use
    Hastebin has a simple and intuitive user interface that is easy to use for quickly sharing text or code snippets.
  • Speed
    Hastebin is designed for speed, allowing users to quickly paste, save, and share text with minimal delay.
  • No Sign-up Required
    Users are not required to create an account to use Hastebin, making it convenient for quick, anonymous sharing.
  • Syntax Highlighting
    Hastebin supports syntax highlighting for many programming languages, which is helpful for developers sharing code snippets.
  • Open Source
    Hastebin is open source, meaning users can view, modify, and contribute to its codebase or even self-host their own instance.

Possible disadvantages

  • Temporary Storage
    Content is stored temporarily and may be deleted after a certain period of inactivity, which may not be ideal for long-term storage.
  • No Authentication
    The lack of an authentication mechanism means there is no way to control access to the content once the link is shared.
  • Manual Management
    Users need to manually manage and keep track of their links because there is no account system to organize saved snippets.
  • Limited Customization
    Hastebin offers limited customization options for users who might need more control over the presentation or behavior of pasted content.
  • Security Concerns
    Given that anyone with the link can access the content, there may be security concerns for sharing sensitive information.

Questions & Answers

As answered by people managing hastebin 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.
