Why Thuban costs so little — the maths in 54 seconds

Why people go Individual

As long as you have Thuban, you have a pair of eyes on your codebase all day every day.

That is the sticky reason to subscribe. Free Thuban gives you a one-off checkup when you remember to run it. Thuban Individual turns thuban monitor into a guardian that keeps scanning, keeps watching, and keeps surfacing new issues every time you're coding — for $9/mo.

If AI is helping write code every day, you need something reviewing that code every day too. Nobody cancels their security guard because nothing bad happened this week.

Free Thuban
One-off checkup

Thuban Individual
A pair of eyes every session
Recurring scans, saved history, trends, and alerts so your codebase is watched every time you code, not just when you remember.
Hero command
thuban monitor
The Individual-tier feature that keeps checking your repo on a schedule and proves ongoing code health over time.
FOR FOUNDERS, INVESTORS & BOARDS

FAQ

Common questions.

Everything you need to know about pricing, privacy, and how Thuban works.

Why is Thuban so cheap?+
Thuban runs on your machine. We do not host your code, store your scans, or run cloud infrastructure on your behalf. Our costs are low, so your price is low.
What exactly do I get at each tier?+
All prices in USD:
Free — $0: Thuban Shield core (1 machine), community rules, Scanner (200 scans, all 69 rules)
Individual — $9/mo: full Shield, full Scanner, priority rules, email support
Team — $49/mo: 10 users, shared dashboards, team rule packs
Business — $299/mo: 50 users, compliance reports, dedicated support
Enterprise — $499/mo: 100+ users, SLA, on-prem option, custom integrations
What is Thuban Shield?+
Thuban Shield is a 5-layer filesystem bodyguard that sits between any AI coding agent and your files. Layers 1-2 and 4-5 are free; Watchers requires the Individual tier or above using your own API key. See the Shield page for the full breakdown.
What is Crucible?+
Crucible is Thuban's adversarial mutation-testing engine — 515 attack-pattern seed files run against the Scanner to prove detection rules actually work. See the Crucible page.
How do I install Thuban?+
The one command that runs everything — Shield + Scanner + Crucible:
npx thuban protect .

No config files needed. Or install globally:
npm install -g thuban

Works on Windows, macOS, and Linux. Requires Node.js 16+.
Can I get an investor-grade audit report?+
Yes. Report tiers range from a free preview to a $249 full audit, generated with thuban investor-report . --company-name="Target Corp". A $999 deep diligence tier is coming soon.

Protect your codebase in the next 60 seconds.

No card required. Just a valid email address and you're in.
