Record. Reveal. Refine.
The official repository for the Active-Pro Debugger and Logic Analyzer family — the recorder of embedded system behavior.
Download · User's Manual · Store · Blog
Active-Pro is a hardware-and-software toolchain that records what your embedded system is actually doing — every signal transition, every protocol event, every stretch of idle time — and lets you replay, inspect, and share that capture later.
Think of it as Wireshark for the wires on your board. Where a logic analyzer shows you waveforms and a debugger shows you breakpoints, Active-Pro records the full behavioral trace of a running system so you can see how the pieces actually fit together over time.
Three products share the same application and capture format:
- Active Debugger — entry-level debug port and signal capture
- Active-Pro — full debugger and logic analyzer
- Active-Pro Ultra — super-speed capture for higher-bandwidth and longer-duration traces
All three work with the free Active-Pro application on Windows, macOS, and Linux. Run the app without hardware attached to demo every feature.

- Buy hardware at activefirmwaretools.com/store, or skip ahead and use demo mode.
- Download the application from activefirmwaretools.com/download — Windows, macOS, and Linux builds available.
- Press Capture. With hardware attached you'll see your signals live. Without hardware you'll get the full demo capture to explore the UI.
- Read the manual at activefirmwaretools.com/usersmanual when you're ready to go deeper.
Captures export to .aft (Active Firmware Trace) — a plain-text format with an embedded AI context block. Copy a capture to your clipboard, paste it into any AI assistant, and ask questions about timing, protocol behavior, or anomalies in plain English.
For tighter integration, the mcp-server folder contains an MCP server that lets Claude Desktop and other AI clients query your captures directly.
