The record

Purpose: Sidekiq is a framework for background job processing that scales applications by performing work in the background.
Data store: Sidekiq stores job and operational data in Redis.
Job model: The client serializes job data as JSON and pushes it into a Redis queue, where Sidekiq server processes pull and process jobs.
Core features: The plans comparison lists scheduled jobs, error handling, a Web UI, a Ruby API, middleware, and long-running jobs across OSS, Pro, and Enterprise.
Pro workflows: Sidekiq Pro adds batches and callbacks for tracking grouped jobs and building more complex workflows.
Pro reliability: Sidekiq Pro uses Redis RPOPLPUSH to protect jobs when a process crashes or receives a KILL signal, and its client retries delivery after transient Redis errors.
Enterprise capabilities: Enterprise includes encryption, rate limiting, periodic jobs, unique jobs, historical metrics, multi-core processing, and rolling restarts, plus Pro features.
Encryption scope: Enterprise encryption protects only the last job argument; error messages and backtraces remain plaintext.
Integrations: Sidekiq's wiki says server processes boot Rails, making the Rails API, including Active Record, available to jobs and workers.
Deployment: The maker documents configuring Sidekiq with Redis URLs through environment variables, including REDIS_URL and Heroku's REDIS_PROVIDER pattern.
Limits: Enterprise licensing is based on production worker thread count; development and staging use is free and unlimited.
Free trial: The maker says it does not offer pre-sales demos or free trials, but a purchased month of Pro or Enterprise may be tried and refunded if the customer is unhappy.
Support: Commercial priority support covers one incident per quarter, has a maximum response time of two working days, and excludes the customer's application and infrastructure.
Audience: The maker's comparison lists hobbyists for OSS, small business for Pro, and medium to large companies for Enterprise.
Price from: $82.92/mo
