About PouchDB and Underlayer

In their own words, as submitted to SaaSHub.

Underlayer

No description of PouchDB 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.

PouchDB 5 features
Underlayer 0 features
  • Offline-first Architecture
    PouchDB is designed for offline-first applications, allowing users to access and interact with data without requiring a constant internet connection. It automatically syncs with a CouchDB-compatible server when a connection is available.
  • Cross-Platform Compatibility
    PouchDB runs in the browser, Node.js, and other platforms, enabling developers to build applications that work consistently across desktop and mobile devices.
  • CouchDB Compatibility
    Being compatible with CouchDB, PouchDB allows developers to easily sync data between the client and server, leveraging CouchDB's replication and conflict resolution features.
  • Easy to Use
    PouchDB provides a simple API that is easy to understand and use, which can speed up the development process, especially for developers familiar with document-based databases.
  • Rich Querying Capabilities
    PouchDB supports MapReduce, Mango queries, and a few advanced indexing features that offer flexible ways to query data based on specific requirements.

Possible disadvantages

  • Limited Built-in Security
    While PouchDB can work offline, securing data at rest or implementing authentication requires additional work, as it does not provide substantial security features out of the box.
  • Database Size Limitations
    When used in the browser, PouchDB's storage capacity is limited by the browser's storage limits, which might not be sufficient for certain applications with large datasets.
  • Performance Overhead
    PouchDB can introduce some performance overhead due to its JavaScript implementation and the use of MapReduce on larger datasets, which may not be as fast as native database implementations.
  • Complex Conflict Resolution
    While conflict resolution is supported, handling conflicts can become complex, requiring developers to implement robust conflict management strategies within their applications.
  • Dependency on CouchDB
    Although PouchDB is designed to work offline, the synchronization capabilities depend on CouchDB (or a compatible server), meaning that certain features may not work without such a backend setup.

Questions & Answers

As answered by people managing PouchDB 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.
