Collaborative reverse engineering tools in 2026
Search for a way to reverse a binary together and most of what you find is dead. The plugins that pioneered this either stopped updating years ago or were archived outright. Here is what actually still works, what died, and what each surviving approach costs you. Statuses checked August 2026.
| Tool | Approach | Engine | Live co-editing | Status | Cost |
|---|---|---|---|---|---|
| reverser.space | Browser sessions, shared by link | Ghidra (hosted) | Yes - real-time, plus AI agents (MCP) | Active, early | Free while early |
| BinSync | Git-backed sync plugin | IDA, Binary Ninja, Ghidra, angr | No - sync on commit | Active | Free, open source |
| Ghidra Server | Built-in shared projects | Ghidra (desktop) | No - check-in and merge | Active, part of Ghidra | Free, self-hosted |
| IDA Teams | Vault-based versioning | IDA Pro | No - versioned check-ins | Active, commercial | Per-seat license |
| CollaRE | Multi-tool file hand-off hub | Tool-agnostic | No - file-based | Stalled (last commit Mar 2024) | Free, open source |
| IDArling | Live sync plugin | IDA Pro | Yes, in its day | Archived, dead since 2021 | - |
| collabREate | Event sync plugin | IDA Pro | Partial | Dormant since 2021 | Free, open source |
The graveyard
What died, and why it matters
IDArling was the proof that reversers wanted real-time collaboration: an IDA plugin with live cursors and instant sync. It has been archived since 2021 and does not work with current IDA versions. collabREate came even earlier and went quiet the same year.
CollaRE took a different angle: a hub for passing project files between tools. Its last commit was March 2024, and file hand-off still means you are emailing databases with extra steps.
The pattern: collaboration bolted onto a single-player desktop tool keeps breaking every time the host tool updates, and maintaining that treadmill burned every one of these projects out.
Still alive
The maintained alternatives
BinSync is the strongest open-source option: a plugin that syncs renames, comments and types through git, across IDA, Binary Ninja, Ghidra and angr-management. It is actively maintained. The trade-off is the model: you sync on commit, like code review, rather than seeing each other work. Everyone still needs their own desktop setup.
Ghidra Server ships inside Ghidra itself: shared projects with check-in, check-out and merge. Free and battle-tested, but you host it, everyone installs Ghidra locally, and conflicting edits meet a merge dialog, not a shared cursor.
IDA Teams is Hex-Rays' commercial answer: vault-based versioning for IDA databases. Solid if your team already runs IDA seats, and priced accordingly. It is versioned check-ins, not live sessions.
Where we fit
reverser.space, honestly
reverser.space is the only one on this list where collaboration is the architecture rather than a plugin: sessions run Ghidra server-side and everyone works the same live session in a browser. Share a read-only link that needs no account, grant editing to work together with peer cursors, or invite an AI agent that joins like a teammate - attributed, permission-capped, on your own API key. It is also the only one that speaks MCP: point Claude Code or any MCP client at a session and your own agent works it with the same tools.
The honest trade-offs: the engine is Ghidra only, and sessions run in our sandboxed cloud - if policy forbids uploading samples to third-party infrastructure, self-hosted Ghidra Server or BinSync is the better fit.
Judge it in one click: a live read-only session, no account needed.
