SampleApp.ai

SampleApp.ai is a web platform and API for API and SDK companies that turns API documentation into interactive live sandboxes with deployable sample applications, so developers can start integrating in under a minute.

Key capabilities include:

• Stripe-style guided onboarding that walks developers through pre-built flows per use case, with steps, code, and a live preview kept in sync
• AI code generation for specific tech stacks, producing sample apps and snippets for frameworks such as NextJS, Vite, Flask, and FastAPI
• One-click API key issuance and instant app launch, plus the ability to fork and customize sample apps
• Team visibility and measurement, including analytics for engagement and API usage tracking, plus versioning, Git sync, access control, and custom branding (CSS)

Pricing: Free (Starter, 3 sample apps/month) and Paid plans including Pro ($49/month), plus Growth and Enterprise plans with custom pricing.

What makes it notable is the focus on a guided, in-browser sample app experience that can be embedded in existing docs (including Mintlify, Fern, and GitBook) and tracked end-to-end, providing measurable developer onboarding compared with static docs and standalone API playgrounds.
