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 OpenWebSearch

One API for every web search provider. Choose the provider that fits each use case and receive every result in one standardized format. Compare the best open-source LLMs of 2026 by benchmarks, context window, and use case. These seven lead the latest open source LLMs on benchmarks and real-world use. OpenAI also entered the open-source space with GPT oss 120b and 20b, though those models are not yet frontier-grade. The data comes from model providers as well as independently run evaluations by Vellum or the open-source community.
