v0 May 12, 2026 Changelog

This update is all about making your coding experience in v0 faster and more powerful. It matters a lot to developers who use v0 to build apps, especially those who want to manage their projects and run code without constantly switching between different windows.

What's new

• Run commands in chat: v0 can now run terminal commands right inside your chat. It will always ask for your permission first before running anything, keeping you in control.
• Rename Vercel projects: If your chat is connected to a Vercel project (your live website), you can rename that project straight from the chat settings instead of hunting through menus.
• OAuth for MCP servers: The platform API now supports MCP servers (external tools that connect to your app) that use OAuth (a secure way to log in without sharing your password). There are new guides to help you set this up.
• Better code editor: The VS Code editor built into your chats now automatically saves your work. It also comes with a brand-new "Vercel Light" theme and an updated dark theme.
• Longer instructions: You can now write much longer custom instructions to tell v0 exactly how you want your project built.

Improvements

• Faster sandboxes: Sandboxes (safe, isolated environments where v0 tests your code) now start over 50% faster on new chats and take up about 500 MB less storage space on your computer.
• Faster loading: The v0.app home page loads much quicker when you open it.
• Lighter prompt input: The text box where you type your messages has been rebuilt to be faster and use less memory.

Fixes

• Permissions fixed: Updates to the default permissions mode now reach everyone, not just brand-new accounts.
• GitHub settings restored: The GitHub section in Settings and the "Manage" button on chats linked to a code repository disappeared recently, but they are back.
• No more freezing: Chat pages used to freeze up when looking at very large "diffs" (the highlighted lines showing what code was added or removed). They now load smoothly.
• MCP headers fixed: Custom auth headers (special security passwords) for connected MCP servers were getting accidentally deleted after the first request. They now stay intact.
• Credit redemption fixed: The pop-up window for entering a usage code used to get stuck on the word "Verifying" forever. It now finishes properly.
• Snowflake reconnection: If your chat is connected to Snowflake (a data platform) and the connection expires, it will now prompt you to reconnect when you open the chat.
