ZenZip

The agent-native backend framework for Node.js.

Durable workflows, queues, schedules, events, state machines, and AI agents on a single Rust-powered runtime — with zero infrastructure. No Redis, no Temporal cluster, no RabbitMQ. npm install is the entire setup.

npm install zenzip

import { zenzip } from "zenzip";

const app = zenzip(); // embedded SQLite store, zero config

// Durable queue — throw = retry with backoff → dead-letter queue
const emails = app.queue("emails", { concurrency: 10, retries: 5 });
emails.process(async (job) => smtp.send(job.data));

// Durable workflow — every step journaled; kill -9 is a test case
const order = app.workflow("order", async ({ step, input }) => {
  const payment = await step.run("charge", () => stripe.charge(input));
  await step.sleep("cooloff", "10m");                       // survives restarts
  await step.run("ship", () => shipping.create(payment));   // memoized forever
});

await app.start();
await order.trigger({ orderId: "o_42" }, { idempotencyKey: "o_42" });

Kill the process anywhere — jobs redeliver, the sleeping workflow wakes on schedule in the new process, agents resume mid-conversation without re-calling the model for completed steps.

What's inside

• Queues — at-least-once delivery, leases + fencing, backoff, priorities, per-key concurrency, fairness, debounce, throttle, rate limits, DLQ.
• Workflows — step-memoized durable execution (Inngest model, not Temporal replay), sleep / waitForEvent / child workflows / version routing.
• Schedules — cron + intervals, timezones, overlap + catch-up policies.
• Events & state machines — atomic outbox, wildcard patterns, persisted FSMs.
• AI agents — durable LLM loops (retry without re-prompting), tools, human approval, memory, multi-agent networks, evals; Anthropic / OpenAI / Gemini / Bedrock.
• HTTP — Express-compatible middleware + router + adapters.
• Production — encryption at rest, retention/GC, health probes, RBAC, CSRF, rate limiting, alerting, multi-tenancy, PII purge.
• Multi-node — point the same API at Postgres.
