Should I use Sidekiq?
Sidekiq is a full-featured background job framework for all Ruby applications. It can scale to thousands of processes and billions of jobs per day. Sidekiq Pro and Sidekiq Enterprise are commercial upgrades which include even more features than the open source version. - sidekiq.org
Depends. Buy if you run Ruby or Rails at real volume and already operate Redis — it's the battle-tested category default. Skip if you're non-Ruby or a simple Rails 8 app; the built-in Solid Queue covers you.

Gotchas - check before you buy
high
Redis eviction or misconfiguration can silently drop jobs — a real worry on the free tier
medium
Licensing is per app per year; unlimited license exists — read the Commercial FAQ before buying
medium
Need unique jobs or batches? That's Pro — the free workaround gem had its own XSS
low
Annual licenses; factor migration cost if you later switch to Solid Queue
