The fastest install is the rdbg-debugger plugin for Claude Code — two slash commands, all five Windows binaries bundled, no separate download. Standalone pre-built binaries are below if you want the daemons without the AI integration. The full source tree is part of the Pro / Enterprise / Embarcadero commercial-support tiers.
rdbg downloads are gated behind a Google sign-in so we can size the user base and reach you with security updates. We log your email, name, IP, user agent, and referrer; nothing is shared with third parties.
Sign in with GoogleThe rdbg-debugger plugin (for Claude Code) is the recommended path — bundles all five Windows binaries and the AI integration. Standalone pre-built binaries, source access, and the wire-protocol schema follow.
Pre-built Windows binaries: rdbgd64.exe (Win64 daemon), rdbgd32.exe (Win32 daemon), rdbgc.exe (CLI), rdbgui.exe (GUI), rdbg-mcp.exe (MCP bridge for AI agents). Same wire on every binary — pick the daemon by target bitness. Compiled with Delphi 12 Community Edition.
The full source tree to build rdbg yourself, plus pre-built binaries for any Delphi version other than 12 CE. Available with a 12-month commercial support contract — see the licensing tiers for what's included at the Pro / Enterprise / Embarcadero levels.
rdbg-debugger plugin v0.19.31 (for Claude Code)The shipped install path for AI-agent integration: install into Claude Code with two slash commands, then drive rdbg with any prompt. Bundles all five Windows binaries (no separate download), plus skills, slash commands, and an autonomous bug-hunter subagent. The MCP bridge auto-switches daemons per launch based on the target's PE machine type, so one config drives both Win32 and Win64 targets. Other MCP-capable agents can wire rdbg-mcp.exe in directly via their own MCP config.
:: In Claude Code:
/plugin marketplace add https://sundaymorning.app/rdbg/.claude-plugin/marketplace.json
/plugin install rdbg-debugger@rdbg
Manual download (offline / archival, not used by /plugin install):
rdbg-claude-plugin-0.19.31.zip.
Standalone protocol.md + JSON Schema for clients building their own driver.
Optional — the pre-built binaries above cover most users. Build from source if you want to tweak the daemon, run on a different toolchain, or trust your own compile.
dcc64.exe for the Win64 daemon, plus dcc32.exe for the Win32 daemon. Both ship in the same RAD Studio install — the IDE build (rdbg.groupproj) handles dispatch automatically.rdbg.groupproj at the repo root is an MSBuild project group. Open in RAD Studio (File → Open Project); the Project Manager shows rdbgd64, rdbgd32, rdbgc, rdbgui, rdbg-mcp, rdbgtest, and the ticker / raisey demo targets. Right-click the group → Build All Projects from Group.
call "C:\Program Files (x86)\Embarcadero\Studio\23.0\Bin\rsvars.bat"
:: Per-target builds pin the right Platform automatically
msbuild rdbg.groupproj /t:rdbgd64 /p:Config=Debug
msbuild rdbg.groupproj /t:rdbgd32 /p:Config=Debug
msbuild rdbg.groupproj /t:Build /p:Config=Debug :: everything
Artifacts land in bin\ alongside rdbgc.exe, rdbgui.exe, and rdbg-mcp.exe. Requires a full RAD Studio install for MSBuild compilation.
Once the binaries are on PATH, the version check confirms everything's wired:
> rdbgd64 --version
0.19.31
> rdbgd32 --version
0.19.31
> rdbgc --version
0.19.31
:: Trivial console round-trip - launches a tiny test target
:: under the matching daemon. Pick by target bitness.
> rdbgd64 --test-launch bin\test-targets\hello\hello.exe
> rdbgd32 --test-launch bin\test-targets\hello32\hello.exe

The five-minute quickstart walks you from a blank session to your first breakpoint hit, with the matching daemon picked for you.
