Django Q2 vs pg-boss

Django Q2 is a Django task queue, scheduler and worker application built around Python multiprocessing. It runs asynchronous tasks with worker pools and supports scheduled, cron and repeated jobs. For task workflows, it offers result hooks, groups and chains. A multi-cluster monitor and Django Admin integration provide monitoring options. Brokers include Redis, IronMQ, Amazon SQS, MongoDB and Django ORM; the project also lists Rollbar and Sentry support for error reporting. Signed and compressed packages are among its listed security features. The documentation says it is tested with Python 3.10 through 3.14 and works with Django 5.2, 6.0 and 6.1. It is self-hosted, with the README describing compatibility with PaaS deployment across multiple instances. The project is free, MIT-licensed software, installed with pip using the package name django-q2. Listed platforms are Linux, macOS, self-hosted and web. Disque support has been dropped.

pg-boss is a Node.js job queue that uses PostgreSQL for background processing and asynchronous job execution. It can add a job in the same database transaction as the data change it belongs to, so the job is created only when that transaction commits. Workers use PostgreSQL SKIP LOCKED to claim jobs without blocking one another, with atomic commit safety; delivery is at least once, so a handler may run more than once. Queue controls include priorities, rate limits, debouncing, concurrency policies, retries with exponential backoff, and dead-letter queues. Scheduling covers cron and RRULE, deferral, and dependency-based workflows. Transaction adapters are available for Knex, Kysely, Drizzle, and Prisma. Supported databases include PostgreSQL, CockroachDB, YugabyteDB, Citus, and PGlite. A dashboard can monitor and manage jobs, queues, and schedules, while a JSON HTTP API proxy serves non-Node runtimes. It is MIT-licensed and self-hosted, with a listed price of free. It requires Node 22.12 or higher or Bun, plus PostgreSQL 13 or higher.
