JobRunr vs pg-boss

JobRunr is a distributed Java library for processing background jobs and scheduling asynchronous work on the JVM. It supports fire-and-forget, delayed, and recurring tasks, and describes jobs as persistent through cluster restarts or failures. The free OSS plan includes enqueueing and scheduling, automatic retries, carbon-aware scheduling, and a simple dashboard; it allows up to 100 recurring jobs depending on the database. Official integrations are available for Spring Boot, Micronaut, and Quarkus, and the library works with Java 8 and later as a jar distributed through Maven Central. Before production use, the guide recommends replacing in-memory storage with a persistent SQL or NoSQL provider. Business adds priority queues, workflows, realtime scheduling, and a transaction plugin; its license covers one production cluster, while development, test, and staging are free and unlimited. Business costs €850 per PRD cluster / month. Enterprise pricing is custom and includes unlimited recurring jobs and clusters, a multicluster dashboard, and Kubernetes autoscaling metrics.

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.
