Details
Supermaven was the speed king of AI code completion. Built by the creator of Tabnine, it focused on autocomplete with very low latency and a massive context window. Cursor acquired Supermaven in November 2024 and folded its technology into the Cursor editor.
On 21 November 2025 Supermaven announced its sunset. Agent conversations ended, paying customers received refunds for their remaining time, and VS Code users were told to move to Cursor. Existing JetBrains and Neovim customers keep free autocomplete for the foreseeable future. There is no reason to start with Supermaven today: Cursor carries its completion technology, GitHub Copilot works in VS Code and JetBrains, and Devin Desktop (formerly Windsurf) offers unlimited Tab completions on its free plan.
v0 is not trying to build your whole app. It does one thing: generate beautiful React components from descriptions or images. And it does that one thing really well. The output uses shadcn/ui and Tailwind, so the code is clean, accessible, and ready to paste into a Next.js project.
The workflow is: describe a component (or upload a screenshot), v0 generates it, you tweak the prompt until it looks right, then copy the code into your project. It is a UI generation tool, not an app builder. If you need a full stack, look at Lovable or Bolt.new. If you need a polished pricing page or dashboard layout in five minutes, v0 is unmatched.
