Reviewers mostly like Sidekick for reducing tab chaos and making work easier: sessions, workspaces, sidebar apps, split view, multiple accounts, shortcuts, and lower memory use come up again and again, especially among people juggling many projects or ADHD-style tab overload. But praise is tempered by recurring complaints about bugs, broken sites or extensions, sluggish CPU spikes for some users, and a learning curve. The sharpest criticism targets pricing, paywalled basics, intrusive status or signature changes, weak support, poor communication, and fears that maintenance has slipped.
