HeimWall

Live

Local macOS scanner that blocks secrets and PII from leaking into AI coding-tool prompts, for engineers who don't want to rely on cloud DLP.

Domain registered 4 months ago

FreeWorks offline
What to know▼
How it works
A macOS app that scans prompts in real time before they reach AI coding tools like Cursor, Claude Code, and Copilot, flagging leaked API keys, credentials, and PII using 47 local detection rules in under 50ms.
What's different
Detection happens on-device before data leaves the machine, and uses soft notifications instead of hard blocks so it doesn't interrupt the coding flow.
Pricing
Free 15MB macOS application for engineers; an early-access dashboard is offered separately for organizations.
Best for
Engineers using AI coding assistants who want to avoid pasting live secrets into prompts.

FreeWorks offline
What to know▼
How it works
A desktop AI coding harness built around open-weight models (DeepSeek, Qwen, Kimi, MiniMax) instead of Claude/GPT, using a structural + lexical code-retrieval engine (Blueprint) that builds a real dependency graph of the codebase rather than embeddings or a vector DB.

Pricing
Free.
Best for
Developers who want to use open-weight models like DeepSeek, Qwen, or Kimi for coding with retrieval built for their limitations.
Watch out
Depends on local tools like Ollama and MCP — offline/no-cloud setup requires configuring those dependencies yourself.

How it works
A clipboard manager for macOS and Windows (beta) that copies text the instant you select it — no Ctrl+C/Cmd+C needed — then long-press to paste, or press Cmd/Ctrl+Shift+V to open a searchable history of your last 200 clips.
What's different
Brings the select-to-copy behavior Linux users know from PRIMARY selection to Mac and Windows; traditional clipboard managers only store history after you explicitly press copy.
Pricing
Free.
Best for
macOS and Windows users who want copy-paste without the extra keystroke.
Watch out
The Windows version is in beta.

What to know▼
How it works

What's different

Pricing
Free.
Best for
Windows power users who currently juggle separate clipboard, snippet, and screenshot tools.
Watch out
Runs locally with no cloud sync — clips stay on one machine unless the app supports cross-device sync elsewhere.
