Overall Score
Based on our independent scoring across 6 dimensions, Sentry scores 89/100 overall versus Axiom's 84/100 — a 5-point margin. Sentry leads on Performance APM in particular. That said, Axiom 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 Axiom and Sentry 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.
Sentry scores higher on Integrations — 95/100 versus 78/100 for Axiom. If integrations is your primary decision criterion, Sentry is the stronger choice in this head-to-head.
Switching between error monitoring tools is generally possible but involves migration effort: exporting your data or configuration from Axiom, re-importing or reconfiguring in Sentry, 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 Sentry on a non-production project first before migrating.
Axiom (84/100) is the better fit for teams who prioritise performance apm — its strongest dimension — and who want a free entry point. Sentry (89/100) is the better fit for teams who prioritise integrations and want a free entry point. If both dimensions matter equally, the overall score winner (Sentry) is the safer default choice.
