Synter sandbox / private alpha
A governed sandbox for programmable paid media.
Prototype deterministic workflows in an isolated developer surface—scoped to an invited workspace, observable by default, and separate from live spend.

Errors should be as usable as success.
Each simulation starts from a known fixture and produces an inspectable result. Agents can branch on stable states, people can review the event trail, and repeated runs remain independently inspectable.

What the private alpha permits—and refuses.
The sandbox is an isolated developer surface. Live-account activation is unavailable in this alpha.

Bring your agent. Keep the blast radius small.
The first cohort will help us evaluate examples, workflow needs, and the usefulness of isolated simulation workflows.
