worldseq

Test business decisions.

worldseq simulates SaaS companies with customers, cash, deadlines, and limited capacity. Humans or agents use the same tools to make commitments, advance the business, and respond when conditions change.

Get startedExplore environments

Play in the dashboard. Connect through Python, TypeScript, HTTP, or MCP.

Hover a component to see how it connects. You can also tap or use the keyboard.

The plan is only the beginning.

A campaign can bring in customers faster than the team can onboard them. Hiring takes time. Annual payments improve cash today while leaving service to deliver tomorrow.

Choose where to spend

Put time and money behind a plan. Work has prerequisites, lead times, and a real cost.

Let the business respond

Customers arrive, invoices fall due, and incidents overlap. Reports can arrive after the events they describe.

Check what changed

Use the evidence to revise your plan. Outcomes are checked against the task’s requirements and the recorded business activity.
