Plango

Plango is a security app for Mac and the AI tools that run on it, built and sold by Acrebase, Inc. of Philadelphia, Pennsylvania. It targets developers who let coding agents such as Claude Code, Cursor and Codex run commands and read files. Plango rates each agent action before it runs, can block dangerous ones, and keeps a log of every event, request, decision and block. It also covers MCP servers, skills and plugins, and moves plain-text keys from .env files into the Keychain.

Beyond agent protection, Plango includes general Mac security features. A phishing guard warns before you type a password into a fake login page, a privacy view shows which apps can use the camera, microphone, screen and keystrokes, and a smart firewall shows what the Mac does online. It can also check projects for libraries with known CVEs and audit app permissions, startup items and extensions. Plango AI runs on the Mac, so files and prompts stay on the device.

Pricing is a single subscription of $4.99 per month, charged when you subscribe and renewing automatically every month until you cancel. Cancelling from the account page keeps access to the end of the paid month. A 7 day free trial needs no card and never turns into a paid plan, though the trial is limited to one device. The subscription works on one Mac at a time and can be moved to a new Mac.

Check the hardware requirements first: Plango needs a Mac with Apple silicon (M1, M2, M3 or M4), macOS 15 or newer, and at least 16 GB of memory. It is Mac-only. Prices are shown in dollars, so ask the vendor about rupee billing or GST invoices if your company needs them. The terms are governed by Pennsylvania law and applicable United States federal law. Support is by a support page or email.
