Stop surprise AI bills and broken agent workflows

Budget enforcement, safe retries, and audit trails for production AI

Enforce cost caps with hard budget limits per request

Prevent partial state writes via transactional boundaries

Guarantee deterministic retries with exact replay semantics

What Neusnap Enforces

Cost-Optimized Routing

Automatically route to the lowest-cost model that meets quality thresholds. Fallback chains execute without manual retry logic.

Cost Enforcement

Per-request budget caps with hard enforcement. Requests abort when limits are reached. No advisory warnings.

Learn more

ACID Transactions

Atomic commits with rollback guarantees. No partial state writes. Deterministic retries with exact replay.

Without Neusnap: Manual Complexity

Multiple failure surfaces. Undefined behavior on partial failures.

Manual Implementation

×Manual try/catch per provider SDK

×Hand-rolled fallback chains

×Undefined behavior on partial failures

×Manual cost tracking with race conditions

×No transactional guarantees

let result;
try {
  result = await openai.chat({
    model: "gpt-4",
    messages: [...],
  });
} catch (err) {
  // Manual fallback
  try {
    result = await anthropic.messages({
      model: "claude-sonnet-3.5",
      messages: [...],
    });
  } catch (err2) {
    // Give up or retry?
    throw err2;
  }
}

// Manually track spend
await db.incrementUsage(cost);

// Update agent state
await db.updateState({
  lastResponse: result,
  context: [...],
});

// Hope nothing failed halfway

With Neusnap

router.run({
  prompt,
  tools,
  routing: "auto",
  maxBudget: 0.50
})

Automatic fallback with deterministic behavior

Enforced budget caps, not advisory

Transactional state with rollback guarantees

Single API boundary

Single API boundary. Deterministic execution. Fewer failure modes.

Who This Is For

Built for production systems running agentic workflows at scale.

DevTools

Fintech

Marketplaces

E-commerce

Internal AI platforms

Not for prototypes, hobby projects, or single-agent experiments.
Built for production workloads with failure budgets.

System Guarantees

Atomic commits: no partial state writes

Deterministic retries: exact replay on failure

Hard budget enforcement: requests abort at limit

Vendor-agnostic execution: no provider lock-in

Explicit failure semantics: no undefined behavior
