Playable, not click-through
Learning through choices and consequences
Choices have consequences that carry forward. Track a score, branch on what someone did, and end differently based on the whole path — then replay to compare what another route changes.
Score & variables
Track points, time, posture — whatever matters in your scenario.
Branching outcomes
The ending depends on the whole path, not just the last click.
Gated choices
Lock or reveal options based on earlier decisions.
Replayable
Take a different path and get a different result.
Use cases
One builder for many workplace decisions
A vendor breach tabletop is one concrete starting point: present the incident, record the room's call, and reveal what follows. The same general Scenario canvas also supports onboarding, teaching, policy practice, guided walkthroughs, and other branching stories.
Tabletop exercises
Guide a team through a branching incident, record each call, and reveal what follows.

ExploreSecurity drills
Practice incident-response and awareness decisions before the pressure is real.
Playable starter: Spot the Phish

Free, and built for everyone
No account, no sign-up, no paywall. It runs in your browser — and it's made so anyone can build, not just play.
Free to use
No paywall, no trial clock, no upsell.
No account
Nothing to sign up for. Just open it and go.
Anyone can build
Made for non-technical people, not just developers.
Private by default
Authoring and play stay local until you choose to export or share. Encrypted snapshot links and live collaboration are available without an account; optional transport services receive ciphertext but can still observe ordinary connection metadata.
See the security model →Draw your first scenario in a minute.
Open the builder with a blank canvas, or explore a use-case shape before drawing your own Scenario. Save it locally, export it as a file, or use an existing sharing mechanism.
