Battle-test AI coding models side by side
Send the same coding prompt to multiple leading models and compare their generated apps and logic side by side.
Watch models construct web apps and websites live, so you can see process and output, not just the final file.
Projects go beyond one-off snippets, testing how well a model structures components, routes, and styles together.
Track which coding models accumulate the most wins over time to identify consistently strong performers.
The fastest way for developers to implement your API
Move past static docs with pre-built, interactive flows tailored to each prospect's specific use case, so developers see exactly how your API fits their problem before writing much code.
The walkthrough shows steps on the left, a live preview top-right and generated code bottom-right, all synced as the developer advances — with snippets produced in their actual tech stack using their own API keys and environment.
Track who started the integration, who is stuck and who finished, measure time-to-first-call by use case, and be notified when prospects complete key steps — turning developer onboarding into a measurable funnel.
Guides can be generated in the frameworks your prospects use — React, Vite, FastAPI, Flask, Express and Go — and embedded in Docusaurus, Fern, Mintlify, ReadMe or GitBook with a short snippet.
