As answered by people managing Softr and Open TestPrep.
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.
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.
Softr's answer
Over 1 million teams use Softr to build and run business operations apps: - Netflix - Google - Stripe - UPS - MIT - Clay - Celonis - Make
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.
