Features

Everything you need to ship bug-free code.

A lightweight SDK that captures what matters, paired with AI that turns context into fixes.

Deep Context

Captures DOM snapshots, Redux & Pinia state, network requests, and console logs at the exact moment of failure. No more “works on my machine.”

DOM Snapshots
Redux / Pinia
Network Logs
Console History

AI Root Cause

Instant diagnosis powered by your source code. The AI correlates stack traces, state changes, and network failures to pinpoint the exact line that broke.

FAQ

Frequently asked questions

What's the performance impact of the SDK?

The SDK adds <5 KB gzipped to your bundle and captures data asynchronously using idle callbacks. In our benchmarks, there is zero measurable impact on First Contentful Paint or Interaction to Next Paint. DOM snapshots and state captures are deferred until an error actually occurs.

Is debugfa.st GDPR compliant?

Yes. All captured data passes through automatic PII scrubbing before it leaves the browser. Emails, passwords, credit card numbers, and auth tokens are stripped by default. You can also configure custom scrubbing rules. For Enterprise customers, we offer self-hosted deployment so data never leaves your infrastructure.

Which frameworks are supported?

The core SDK works with any JavaScript application. We have first-class integrations for React (including Next.js, Remix, and Gatsby), Vue (Nuxt included), and Svelte. Angular support is in beta. State capture works with Redux, Pinia, Zustand, and Jotai out of the box.

How does the AI auto-fix feature work?

When an error is captured, the AI analyzes the stack trace against your connected source code repository, correlates it with the captured DOM state and network context, and generates a targeted patch. The fix is opened as a GitHub pull request that you can review, modify, and merge like any other PR. The AI never pushes directly to your main branch.

Can I self-host debugfa.st?

Yes. The entire stack is open-source and designed for self-hosting. Enterprise customers get Helm charts, Terraform modules, and dedicated support for deploying on AWS, GCP, or Azure. The self-hosted version includes all features with no license restrictions.

How does debugfa.st compare to Sentry?

Sentry is a great tool for error tracking. debugfa.st goes further by capturing full DOM snapshots and application state at the moment of failure, then using AI to diagnose root causes and generate fix PRs automatically. Think of it as error tracking + session replay + AI copilot in one platform.
