How it works

Stage, review, apply

Review before production

Every mutation staged. Every change approved.

Session #4815 — Price adjustment
Session #4816 — Batch import
Session #4817 — User migration
Session #4818 — Subscription renewal
Session #4819 — Inventory sync
Session #4820 — Customer update
Session #4821 — Refund processing
Session #4822

Order refund — 3 tables staged, pending approval.

3 mutations•2 reviewers
Session #4823 — Ledger entry
Session #4824 — Order update
Session #4825 — Stock reconciliation
Session #4826 — Payment capture
Session #4827 — Address change
Session #4828 — Discount apply
Session #4829 — Tax adjustment

Works with your stack

Drop-in integration with any agent framework.

tools/refund.py
# Wrap your connection
db = Sandbox.connect("postgres://...")
# Writes stage instantly
db.execute("UPDATE orders...")
# Submit for review (non-blocking)
proposal = db.propose()
# → Webhook fires on approve/reject

Staging is instant. Approval happens async via webhooks.

Proxy Modes

Two modes, one proxy

From autonomous agents to CI pipelines, one proxy handles database isolation everywhere.

WIPERdev

Test freely, discard safely

All mutations staged in shadow tables, discarded at session end.

AI Coding Agents

Self-test database features in zero-risk sandboxes

CI/CD Testing

Replace slow Docker resets with millisecond session wipes

Local Testing

Test real SQL and constraints without fake mocks

AGENTICproduction

Stage, review, approve

All mutations staged for human review. The safe default for production agents.

Production Guardrails

Prevent accidental database corruption and wipes

Staging Previews

Preview changes on production-like data safely

Bulk Operations

Stage large updates for review before applying

Set mode via connection string: ?mode=wiper
