Stop paying Sentry's per-event bills. OpenErrorAPI is a drop-in replacement — change only your DSN string. Every official Sentry SDK works without a single line of code change.
EU-hosted · GDPR-native · AI-agent API · Flat-fee pricing.
Built for independent developers, SaaS teams, and agencies who are tired of Sentry's per-event billing model punishing them every time their app gets popular. You should pay for the service, not for how many bugs your users trigger.
Error tracking done right — Sentry-wire-protocol compatible, EU-hosted, with an AI-native API layer you won't find anywhere else.
PHP sentry/sentry, JavaScript @sentry/browser, Python sentry-sdk, Node.js, Flutter, Ruby, Go — all official Sentry SDKs speak our ingest protocol natively. Change one line. Ship the same day.
The same TypeError thrown from 10,000 requests creates exactly one issue — not 10,000 noise alerts. Our fingerprinting algorithm groups by exception type and in-app stack frames, stripping dynamic values like UUIDs and IDs. You see the signal, not the noise.
Raw events land in ClickHouse — a columnar database built for exactly this workload. Sparklines, frequency charts, and event history queries run in milliseconds regardless of volume. The control plane stays in MySQL for transactional reliability; ClickHouse handles the scale.
Fire alerts on new issues, regressions, or frequency spikes via email, webhook, or Slack. Smart deduplication ensures the same issue doesn't fill your inbox — one alert per issue per hour, no matter how many events arrive. Configure per-project alert rules, not global noise.
Issue scoped session keys let AI agents read issues, inspect stack traces, and resolve or ignore problems — all programmatically. Give Claude Code access to your error stream and let it triage overnight. Hard-blocked from billing, keys, and member management. This is the layer no other affordable error tracker offers.
Sentry charges per event. That means the busier your app, the higher the bill — exactly when you can least afford surprises. We charge a flat monthly fee by plan tier. Deploy a viral feature, absorb a spike, ship confidently. Your error tracking bill stays the same.
If you're starting fresh, three steps gets you capturing exceptions in minutes.
Sign up, create a project for your app (PHP, JS, Python, whatever), and copy the DSN string. It looks like: https://key@openerrorapi.com/42
Replace your existing Sentry DSN with the OpenErrorAPI one. All your captureException, addBreadcrumb, and setUser calls work identically. Zero other changes required.
Exceptions appear in your Console dashboard, grouped by fingerprint. Set up alert rules and you'll get notified within seconds of a new error type — before your users do.
Billed per bug, not per crash. A bad deploy that emits two million copies of one error still counts as one issue.
