An HTTP 200 delivery to an edge proxy does not mean your background worker provisioned the customer. OutcomeReplay monitors outcome contracts, catches silent pipeline dropouts, and enables targeted, idempotent replay without duplicate side-effects.
Simulate Asynchronous Worker Dropout & Safe Replay
Deploy In Under 60 Seconds
Scan for async ack traps in your repository or run continuous outcome assertion in CI/CD.
// 1. Audit your repository for missing idempotency & async ack traps:
npx outcomereplay scan --dir ./src
// 2. Generate a tamper-evident SOC 2 CC7.4 compliance pack:
npx outcomereplay audit --org "Acme SaaS" --output ./audit-pack
Embed Real-Time Event Parity Proofs
Prove zero silent drops and cryptographic outcome reconciliation directly in your GitHub README and status page.
Declarative Event-to-State Semantics
Replace manual database queries and ad-hoc log searches with deterministic contracts.
Map provider-specific event keys to your internal database IDs. OutcomeReplay waits through normal asynchronous queue latency before triggering an outcome check.
Never overwrite newer business states. If an account is already canceled, an out-of-order delayed activation event is flagged as SUPERSEDED and safely neutralized.
Replay actions inject strict Idempotency-Key headers. If a repair times out, OutcomeReplay probes the receipt key instead of blindly dispatching a duplicate mutation.
Transparent, Enterprise-Ready Plans
All licenses include offline cryptographically signed HMAC verification. Zero customer data leaves your perimeter.
Essential outcome reconciliation for single-source hobby or indie SaaS projects.
Continuous reconciliation and discrepancy inbox for fast-growing SaaS integration teams.
Automated targeted idempotent repair and audit proof for mission-critical revenue webhooks.
High-throughput streaming multi-region fleet reconciliation for enterprise platforms.
Unlike blind webhook gateways that simply resend raw HTTP payloads, OutcomeReplay checks declared target idempotency contracts first. Replays are dispatched with deterministic Idempotency-Key headers. If a target doesn't declare idempotency support, automatic repair is strictly disabled.
No. Under Spekra's Zero-Trust architecture, OutcomeReplay operates via bounded, read-only HTTP outcome checks or customer-operated local runners. No production database credentials, API master keys, or unredacted customer PII ever leaves your network.
OutcomeReplay treats timeouts as unknown states. Rather than blindly retrying, it executes an immediate outcome probe using the same idempotency key to inspect whether the target actually processed the record before deciding whether to retry.
If a customer downgrades to Plan A, and a delayed Plan B upgrade event arrives minutes later, replaying Plan B would overwrite the customer's intended state. OutcomeReplay checks the object's version/timestamp and marks outdated events as SUPERSEDED, preventing stale overwrites.
