GitHub Goes After Vibe Coding Fans with the Public Preview of GitHub Spark

Microsoft-owned collaborative coding platform GitHub has launched a large language model-powered vibe coding feature dubbed GitHub Spark in public preview, promising to go from "idea to deployed app in minutes" — providing you're a paying Copilot Pro+ subscriber, at least.

"Today we're releasing GitHub Spark," Microsoft chair and chief executive officer Satya Nadella announced of the subsidiary's latest feature, "a new tool in [GitHub] Copilot that turns your ideas into full-stack apps, entirely in natural language. I've enjoyed creating with Spark myself, but even more, I’ve enjoyed seeing what you're building."

GitHub Spark is the latest in a string of "vibe coding" platforms, which use large language model (LLM) technology to turn natural-language prompts into code and other resources — moving LLMs beyond simply autocompleting lines of code or generating boilerplate into creating the app itself, with typically mixed results.

Powered by Anthropic's Claude Sonnet 4 model, GitHub Spark can be used in three ways: pure vibe coding with natural language queries, a visual editing environment, or more traditional manual coding with LLM assistance. Once written, apps can be published "with a single click," and the same goes for creating a GitHub repository for the project. The apps can even integrate connectivity to other LLMs, with GitHub promising support for "OpenAI, Meta, DeepSeek" and other models with "no API [Application Programming Interface] key management needed."

While the preview is open to the public, though, it doesn't come for free: Spark is only available to GitHub Copilot Pro+ subscribers, which costs $39 a month or $390 per year. For that, users get "up to 375 Spark messages included per month," after which additional feels will apply — and while subscribers can build "an unlimited number of apps," they will be limited to "10 active app building sessions at a time."

More information on GitHub Spark is available on the GitHub website; the company has confirmed it plans to provide access to those not subscribed to Copilot Pro+ "in the coming weeks," but likely with more stringent usage restrictions.
