About HeimWall

Signal, not surveillance. See how your engineers use Cursor, Claude Code, and Copilot: catch leaked secrets, PII, and confidential data, without blocking them or reading their prompts. Nothing sits in your send path, your prompt reaches the tool untouched, and what you type into an AI tool is never sent to us. To read your prompt before it is sent, the app reads the composer through the macOS Accessibility API and watches the clipboard. Accessibility is a wide permission and macOS does not offer a narrower one for this.

About Wasmer SDK

Today we're releasing a new SDK that finally fulfills the mission of Wasmer: run anything, anywhere. ), PHP and even Postgres can now run as sandboxed libraries inside your Python, JavaScript or Rust applications. The sandbox runs locally, as part of your application, with 0.1ms of sandbox creation time, 10-20x faster command runs, and 2-10x faster startup times compared to Docker and Remote Sandboxing alternatives (see benchmarks below). This is probably my favorite part: the SDK also works fully inside the browser.
