Squasher

Squasher is error monitoring with AI triage built in. Every error gets a root cause analysis, severity assessment, and fix suggestion — on every plan, including free.

AI Triage on Every Error

Every error is analyzed by AI. Root cause, severity, fix suggestion. Free on all plans — no per-seat AI fee.

Dual Ingestion

SDK drops AND log drains from Vercel and Railway in one dashboard. No code changes needed for log drains.

Tiny SDK

Under 5KB gzipped client bundle. Sentry ships 30KB+. Less overhead, same visibility, better Lighthouse scores.

Auto-Fix PRs

On Team plan, Squasher generates fix PRs in sandboxed environments and runs your tests before opening the PR.
