Overview

  • GitHub has opened Spark to Copilot Pro+ subscribers in a public preview phase and plans to expand access to other customer tiers in the coming months.
  • Developers can generate complete full-stack applications using natural language prompts that handle both frontend and backend construction without any manual configuration.
  • Each Spark-generated app can be published with a single click and is stored in a GitHub repository preconfigured with GitHub Actions and Dependabot.
  • The service is powered by Anthropic’s Claude Sonnet 4 and lets users overlay AI-driven features from OpenAI, Meta, DeepSeek, xAI and more without needing API keys.
  • Creators can iterate on their projects via visual editing controls, GitHub Copilot code completions or by opening a codespace to engage Copilot agents for further refinement.
