VineScale

Free beta for AI coding agents

Stop your coding agent before it breaks production.

VineScale knows your production databases and your infrastructure. When an agent is about to run something that would break them, VineScale asks you or blocks it first.

Or join the waitlist for the Team tier.

Example
agent      psql prod -c "ALTER TABLE orders DROP COLUMN status"
vinescale  blocked  drops column orders.status on prod-db (production), read by 2 services
           ask the user to run it

Knows what's real

It maps your production databases and infrastructure, and the code that reads each table, so it judges an action by what it would actually touch.

Warns or blocks

Risky actions get a warning. Actions that would break something get stopped before they run, with the reason in plain words.

Runs beside your agent

A hook that runs alongside Claude Code, Codex, Cursor, Antigravity and Grok Build, on your own machine.

Questions

What is VineScale?

VineScale is a safety gate for AI coding agents such as Claude Code, Codex and Cursor. It knows a team's production databases and infrastructure, and warns about or blocks an agent's action based on what that action would break. Cross-repo dependencies are coming next.

Is VineScale available yet?

Yes, as a free beta. The gate for Claude Code, Codex, Cursor, Antigravity and Grok Build installs with one command on macOS, Linux and Windows. We're testing it with early users and working out the kinks, and we plan to build a bigger and better version over time. Try the free beta, or join the waitlist below for early access to the Team tier.

How much will VineScale cost?

The gate is free for Claude Code, Codex, Cursor, Antigravity and Grok Build, during the beta and after it. The Team tier, with shared rules for the whole team and an audit log, is planned at $25 per developer a month.

Which coding agents does VineScale work with?

Claude Code, Codex, Cursor, Antigravity and Grok Build, in TypeScript, Python and Go projects. All of them are in the free gate. Support for Codex, Cursor, Antigravity and Grok Build is new in version 0.2.0 and is in beta; the known limits say what that means.

How do I install VineScale?

Run one command. On macOS or Linux, curl -fsSL https://vinescale.com/get.sh | sh. On Windows PowerShell, irm https://vinescale.com/get.ps1 | iex. It installs into your own user folder with no admin rights and adds the gate to each supported coding agent it finds. A Claude Code plugin and Scoop are also available; see the install docs.

Does VineScale send my code or data anywhere?

No. The gate makes no network calls when it decides and sends nothing to VineScale. Its index and its log stay in ~/.vinescale on your machine. The only downloads are the vine build itself, from GitHub, when you install or update it.

How is VineScale different from Claude Code's permission rules and hooks?

Permission rules and hooks judge a command by its text, so they can't tell a harmless table from one that another service reads. VineScale judges an action by what it would actually touch in production, and next in the repos that depend on yours. You can set up rules and hooks today with our guide to stopping Claude Code from running destructive commands.
