As answered by people managing Softr and Underlayer.
Softr's answer
We launched Softr with a single vision: to give 1 billion business users the ability to build the tools they need — without relying on developers, without learning to code.
Softr is now powering over 1 million builders worldwide - including companies like Netflix, Google, Stripe, UPS, and Clay, who build and run the systems that power their business operations.
We’re a fully remote, distributed, and diverse team of curious, ambitious, and driven individuals.
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.
Softr's answer
Many app builders or out-of-the-box tools are either too rigid, too expensive, or fall apart the moment real users and real data are involved. Softr is different because it's built for actual business use from day one.
Describe what you need, and the AI Co-Builder generates a fully functional app — database, logic, and UI already connected. No generated code to debug, no developer needed to make it production-ready.
From there, you stay in control: customize through prompting or visual editing, manage data in Softr Databases or connect to existing tools, set up granular permissions, and connect to Softr MCP. As your business grows, your portal grows with it — without starting over or calling in a developer.
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.
Softr's answer
Over 1 million teams use Softr to build and run business operations apps: - Netflix - Google - Stripe - UPS - MIT - Clay - Celonis - Make
Underlayer's answer:
it's pre-launching
Softr's answer
Unlike pure vibe coding platforms, Softr puts a clear boundary around what AI can generate. Business teams can customize the UI, without asking an LLM to generate or manage the security model, backend, credentials, or infrastructure.
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.
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.
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.
