ChimpbaseBuild complex backends with fewer moving parts.

PostgreSQL-backed backend primitives for software that needs more than request-response, without adding a distributed systems stack before it is necessary.

Get Started

GitHub

Actions

Business operations that can be called from HTTP, CLI, workflows or other actions.

Workers & Queues

Durable background execution with retries, dead letter queues, and configurable concurrency.

Subscriptions

Internal pub/sub reactions with idempotency support for replay safety.

Cron

Recurring work with smart backlog handling — resumes from the current slot after downtime.

Workflows

Long-running business processes that survive time, restarts and retries.

Plugins

Composable plugins for auth, webhooks, REST collections, and more.

Quick Start

Install the Bun host:

bash

bun add @chimpbase/bun

Start with PostgreSQL:

import { createChimpbase } from "@chimpbase/bun";

const chimpbase = await createChimpbase({
  storage: { engine: "postgres", url: process.env.DATABASE_URL! },
});

chimpbase.register({ createCustomer });

chimpbase.register(
  worker("customer.sync", syncCustomer),
  cron("billing.rollup", "0 * * * *", runBillingRollup),
);

Then start the runtime:

await chimpbase.start();

PostgreSQL First

Chimpbase uses PostgreSQL as both your application database and your coordination layer:

application data in PostgreSQL
queue state in PostgreSQL
cron schedule state in PostgreSQL
workflow state in PostgreSQL

SQLite and in-memory storage are available for local development and tests.
