GitHub Spark brings full‑stack app building to plain English

GitHub Spark is now live in public preview, and it builds working apps straight from plain English prompts. Microsoft launched the new tool under GitHub’s platform to make full-stack development accessible without touching a line of config. The tool is only available to Copilot Pro+ subscribers for now.

Spark pulls together GitHub’s hosting, code generation, AI services, and deployment into one place. No dev environment setup, no back-and-forth between services, just one interface that handles every part of the pipeline from typing the idea to shipping the live app. At least according to CEO Satya Nadella.

Users type app ideas and get full-stack builds

With GitHub Spark, you just type something like, “Create a website that recommends movies based on my mood,” and the system kicks off a full-stack build. It sets up both frontend and backend, includes AI functionality, and skips all the manual setup.

Everything runs on Claude Sonnet 4, a large language model that parses the natural language prompt and converts it into production-ready code. Spark doesn’t ask for manual server configs, API setups, or deployment plans. It does all of that on its own.

There’s no need to touch hosting settings either. Spark manages web servers and auto-deploys the final build. That means users don’t need to know anything about load balancers, SSL, or even how to point a domain. It handles the boring stuff while keeping the repo linked to your GitHub account.

The system also reportedly supports AI integration without API keys. Instead of users digging through docs or developer portals, Spark plugs in models from OpenAI, Meta, DeepSeek, and xAI. It builds things like chatbots, summarizers, or recommendation engines directly into the app, using those models under the hood.

And when it’s ready, a single click pushes the app live online. No AWS setup. No Heroku. No deployment script. Just “publish.”

GitHub Copilot agents expand collaboration and coding options

Spark is built to support different workflows. You can start with a natural language prompt, drag elements with visual controls, or get into the actual codebase if you want to tweak details manually. GitHub Copilot remains embedded in the process, offering live completions, code suggestions, and help when writing logic.

Every app made in Spark automatically gets its own GitHub repository. This includes the usual devops stack GitHub Actions for CI/CD pipelines and Dependabot for package updates and vulnerability alerts. So users who want to scale, monitor, or integrate with other systems can go straight into a devops-ready repo.

Spark also supports launching into a GitHub Codespace. From inside the Spark UI, users can spawn a cloud-based coding environment and bring in GitHub Copilot agents. These agents can be assigned tasks like debugging, adding new features, or fixing issues. It’s not just autocomplete—these are AI tools that take tasks off your plate and execute them directly inside the repo.

The agents are capable of handling everything from logic revisions to file restructuring. Developers can collaborate with them as if they were remote team members.

Spark also covers user authentication, database setup, and web hosting, all without writing boilerplate code. You don’t need to spin up a PostgreSQL container or wire up OAuth, it’s already included in the setup Spark runs in the background. If your app needs login functionality, or persistent data, it’s baked in.

Spark’s current build emphasizes speed over complexity, but everything stays editable. After the initial code is generated, users can dive into files, change what they want, or bring in collaborators. Because everything runs through GitHub, it fits naturally into teams already working on version-controlled software.
