GitHub Spark is Now Available in Public Preview for Copilot Pro+ Subscribers

GitHub today unveiled Spark, a powerful new Copilot-powered tool certified in public preview for Copilot Pro+ users. Spark empowers developers to swiftly build and launch full-stack web apps using only natural language, removing traditional setup friction.

With Spark, developers can describe an idea and watch as it materialises into a Prism-powered application—complete with backend logic, intelligent LLM integration (e.g. Claude Sonnet 4), hosting, security tools, and deployment pipelines—all within minutes.

"With GitHub Spark, you can describe what you want in natural language and get a fullstack web app with data storage, AI features, and GitHub authentication built in. You can iterate using prompts, visual tools, or code, and then deploy with a click to a fully managed runtime," GitHub said.

Spark also offers one-click deployments, built-in GitHub Actions, Dependabot support, and the option to open a Codespace for deeper iteration or trigger a Copilot coding agent task.

GitHub highlights key benefits:

• Natural language to working app—no setup or configuration overhead
• Automated inference tools—enable AI features without managing API keys
• Copied deployment pipelines—from code to cloud in seconds
• Flexible development inputs—use plain text, visual editors, or code, all powered by Copilot completions

Spark's rollout addresses the widening gap between ideation and implementation. It's part of GitHub's Copilot evolution, aiming to serve one billion developers with accessible AI-first app creation.

The preview is currently limited to Copilot Pro+ subscribers, with plans to expand availability.
