Never google EADDRINUSE again.

EnvWizard silently detects jammed ports, evicts zombie dev servers with a protected safety shield, and auto-heals missing environment variables directly on file save.

Engineered for Flow State

AI coding is fast until local ports and environments collide. EnvWizard eliminates friction without noise.

⚡

Zero-Click Port Unjammer

Automatically clears jammed background ports in under 50ms before your next run command crashes with EADDRINUSE.

🧩

AST AI-Variable Auto-Healer

When Cursor or ChatGPT introduces new process.env or os.getenv calls, EnvWizard detects the code diff on save and offers 1-click template filling.

🧹

1-Click Clean Slate

Switching branches or projects? Flush all orphaned background development servers across all ports in a single click from the status bar.

Safety by Design

Careful execution. EnvWizard never blindly kills processes or touches your system daemons.

Protected Process Shield

Built-in kernel blacklist safeguards your system. EnvWizard will refuse to target OS window managers, IDE instances, or Docker containers under any circumstances.

  • ✓ Protected: Code.exe, Cursor, dockerd, explorer.exe
  • ✓ Graceful two-stage shutdown (polite signal $\rightarrow$ 800ms grace)
  • ✓ Non-destructive: preserves existing .env formatting and comments

100% Offline & Private

Runs strictly on your local machine using standard system sockets. Your API keys, code files, and environment values never leave your device.

  • ✓ Zero network telemetry
  • ✓ Offline cryptographic license validation
  • ✓ Zero analytics trackers

Frequently Asked Questions

Does EnvWizard transmit any environment variables or code?

No. EnvWizard operates completely offline. Port scanning uses native system commands (netstat, lsof, ss) and AST checks run locally in your editor process. Zero telemetry is collected.

How does the Pro License work?

Pro is a $9.99 one-time purchase with no subscriptions. Each license allows activation on up to 3 personal developer machines (e.g. work laptop, home PC, desktop).

Will it accidentally kill system daemons or Docker?

No. The Protected Process Shield has an un-bypassable blacklist protecting Docker, operating system shells, window servers, and IDE instances. If an unrecognized process holds a port, EnvWizard shows an approval card before taking action.

Which code editors are supported?

EnvWizard works across VS Code, Cursor, and Google Antigravity. It is distributed via the Visual Studio Marketplace and Open VSX.
