Sidekiq 8.0: Improvements to the Web UI | Mike Perham

04-Apr-2025 15
Since its release last month, Sidekiq 8.0 has been very smooth with few reported issues. I’ve been quite happy with the rollout and wanted to provide a little more context about the changes. My goals for any user-friendly, high quality software is to reduce dependencies and keep it simple. Sidekiq 8.0 brings a significant overhaul to its Web UI and these changes further those goals. The Web UI was introduced in 2012 in Sidekiq 0.9 and used Sinatra for its framework along with Twitter Bootstrap for CSS. Sidekiq 4.2 removed the Sinatra dependency (thanks @badosu!) and made the Web UI a plain Rack app with no framework.
