The Ghostwriter alternative when free stops scaling.
Ghostwriter is a free, open-source project-management and reporting tool, popular with red teams and self-host-only. It is excellent and costs nothing. Cairn is the commercial step up: the same reporting plus scanner imports, a client portal, retests, pre-sales and SoWs, and on-prem AI, supported, with a managed-SaaS option.
Reporting is table stakes. The lifecycle is the difference.
On core reporting and delivery, both are capable. The gap opens on everything around it: Ghostwriter focuses on part of the engagement; Cairn owns the pre-sales, scoping and pricing that get you there, and the delivery that follows.

Ghostwriter marks are drawn from its public 2026 documentation and are directional, not hands-on tested. Ghostwriter is free and open-source and leads on red-team operations Cairn does not target at all (C2/oplog integration, covert-infrastructure tracking). On the engagement-platform capabilities compared here, Cairn is ahead.
The number, up front.
Published, per seat, billed annually. On-prem from a stated $30,000/year floor. A five-person firm on the Team tier pays $745/month, all in — replacing a CRM, a proposal tool, e-signature, a reporting platform and a portal.
BSD-3-Clause open-source, self-hosted via Docker/CLI, no license fee; SpecterOps develops it and offers no paid SaaS tier.
