That said, Pusher may still be the right choice if the dimensions where it scores higher match your specific priorities — the radar chart above shows the full profile side by side.
Both Knock and Pusher offer a free tier, so entry-level cost is not a differentiating factor. Compare the feature and usage limits of each free plan to see which gives you more headroom before a paid upgrade is needed.
Knock scores higher on Channel Coverage — 88/100 versus 40/100 for Pusher. If channel coverage is your primary decision criterion, Knock is the stronger choice in this head-to-head.
Switching between notification services tools is generally possible but involves migration effort: exporting your data or configuration from Knock, re-importing or reconfiguring in Pusher, and updating any API integrations or environment variables in your codebase. The effort scales with how deeply embedded the tool is in your stack. Test Pusher on a non-production project first before migrating.
Knock (87/100) is the better fit for teams who prioritise developer ux — its strongest dimension — and who want a free entry point. Pusher (72/100) is the better fit for teams who prioritise developer ux and want a free entry point. If both dimensions matter equally, the overall score winner (Knock) is the safer default choice.
