Show HN: Sora 2 API Playground (sora2.sshh.io)

Sora 2 API Playground is a lightweight, browser-based demo that lets developers experiment with OpenAI’s Sora video-generation API by entering their OpenAI API key (which the app stores locally in the browser). The playground provides a quick, zero-install way to generate videos using the Sora endpoints, making it easy to test prompts, parameters, and workflows without wiring up a backend or managing server-side secrets. It was shared on Show HN to invite feedback and help others prototype video capabilities. For the AI/ML community this matters because it lowers the barrier to hands-on exploration of multimodal generation—useful for prototyping UX, content pipelines, and integration patterns. Key technical implications: your API key is retained only in the client (local storage), so you avoid sending credentials to third-party servers but still need to manage billing, rate limits, and compliance with OpenAI policies. The playground accelerates iteration on prompt design and parameter tuning for video outputs, while reminding users to consider cost, safety, and deployment hardening (server-side key management, input filtering) before production use.
