Persistent

Every session is part of your .luma project. REPL history, instrument config, traces, and notes survive crashes and restarts — a banner lets you Re-Spawn or Re-Attach in one click.

Scriptable

A live JavaScript REPL inside the target process, with first-class values you can inspect, expand, and right-click to jump to memory or disassembly. Autocompletion backed by the runtime's own globals.

Extensible

Drop in a Hook Pack — a JSON manifest plus a JS module — to add your own instrument with custom icon and toggleable features. Built-in package manager and compiler means import just works.

Collaborative

Invite colleagues into a shared lab. Notebook entries, sessions, chat, and presence sync in real time. GitHub auth means no accounts to manage.

Sessions

Pick up exactly where you left off.

Create a session and Luma remembers it. If the process dies, crashes, or you simply close the lid and come back next week, the REPL history, hooks, captures, and notes are still there.

A banner appears at the top of the window offering a single click to Re-Spawn or Re-Attach, and the workspace rehydrates around you.

Captures

Step through every call, instruction by instruction.

Pick any tracer hook, flip Trace instructions, and every call lands in the sidebar as a capture. Open one and Luma replays the run as a control flow graph — with the full register state pinned to whichever instruction you're inspecting.

REPL

JavaScript values, first-class.

Every value you evaluate is rendered as an inspectable object. Expand, collapse, follow references. Right-click any NativePointer to jump straight to a hex dump or a live disassembly view — powered by radare2.

Collaboration

Reverse engineer, together.

Invite friends or colleagues into a shared lab. Sessions, REPL transcripts, instruments, captures, notebook entries, and presence all sync in real time, while the chat lives right next to the work. GitHub auth means no accounts to manage.
