Sidekiq

It is an open-source framework that helps you to create, process and manage your background jobs, i.e. operations you don't want to put in your request processing pipeline. It supports all kind of background tasks – short-running and long-running, CPU intensive and I/O intensive, one shot and recurrent.

Background-only application which launches and runs other applications, or opens documents, at specified dates and times.

It is an alternative PHP FastCGI implementation with some additional features useful for sites of any size, especially busier sites. It includes Adaptive process spawning, Advanced process management with graceful stop/start, Emergency restart in case of accidental opcode cache destruction etc.

Background jobs can be any Ruby class or module that responds to perform. Your existing classes can easily be converted to background jobs or you can create new classes specifically to do work. Or, you can do both.

Beanstalks's interface is generic, but was originally designed for reducing the latency of page views in high-volume web applications by running time-consuming tasks asynchronously.

The fastest, most reliable, Redis-based queue for Node. Carefully written for rock solid stability and atomicity.

Delayed_job (or DJ) encapsulates the common pattern of asynchronously executing longer tasks in the background. It is a direct extraction from Shopify where the job table is responsible for a multitude of core tasks.

Kue is a feature rich priority job queue for node.js backed by redis. A key feature of Kue is its clean user-interface for viewing and managing queued, active, failed, and completed jobs.

Que is a high-performance alternative to DelayedJob or QueueClassic that improves the reliability of your application by protecting your jobs with the same ACID guarantees as the rest of your data.

Redis -> Sidekiq == Faktory -> Faktory. Faktory is a server daemon which provides a simple API to produce and consume background jobs. Jobs are a small JSON hash with a few mandatory keys.

It is a simple, reliable & scalable background processing library for Clojure. It has a transparent design & cloud-native architecture.

It is a cross-platform Unix init scheme with service supervision, a replacement for sysvinit, and other init schemes. It runs on GNU/Linux, *BSD, MacOSX, Solaris, and can easily be adapted to other Unix operating systems.

It is a job queue for PostgreSQL running on Node.js. It allows you to run jobs (e.g. sending emails, performing calculations, generating PDFs, etc) "in the background" so that your HTTP response/application code is not held up. Can be used with any PostgreSQL-backed application. Pairs beautifully with PostGraphile or PostgREST.

Posthook provides an API for scheduling tasks at specific times where the only requirement is the ability to make and receive HTTPS requests.

Workq is a job scheduling server strictly focused on simplifying job processing and streamlining coordination. It can run jobs in blocking foreground or non-blocking background mode.

It is a background server process for processing messages from Google Pub/Sub. It was designed to be an efficient, configurable process that easily integrates into any ruby app.

It is a DB-based queuing backend for Active Job, designed with simplicity and performance in mind. It can be used with SQL databases such as MySQL, PostgreSQL, or SQLite.

Fireworq is a lightweight, high-performance job queue system available from any programming language which can talk HTTP. It works with a single binary without external dependencies.

TaskBotJS is a job queue and processing service for NodeJS applications. Using Redis as a background store, TaskBotJS allows you to offload long-running jobs away from your web application and handles all the rough edges involved: job scheduling, handling failures and retries, priority queueing, and the works

It is a command-line interface (CLI) tool that makes it easy to run background services by adding a few lines to a configuration file. These services are managed by Supervisord, a process control system that ensures that all processes are kept up and running. With Porter, you don't have to manually start and manage background services in multiple terminal tabs.

It is a zero-infrastructure Node.js background jobs platform to easily offload APIs, build resilient third-party API integrations, and more.

It is a distributed and high-performance task scheduling framework that supports multiple cronjobs, delay tasks, workflow, lightweight distributed computing, and unlimited horizontal scaling, with high scalability and fault tolerance.

It is a robust high-performance job processing system for Go and Postgres. It encourages the use of the same database for application data and job queues. By enqueueing jobs transactionally along with other database changes, whole classes of distributed systems problems are avoided.
