How it works

Error to fix in three steps

01

Integrate

Add one script tag to your app. Takes 5 seconds. No config, no SDK, no build step.

02

Detect & Analyze

Errors are captured, classified by severity, and deduplicated. AI reads your source code to understand the root cause.

03

Fix via PR

A pull request with the fix lands in your repo. Review it, merge it, move on. No debugging required.

Features

Everything you need to ship stable code

Automatic PRs

AI reads the error, reads your code, writes a fix, and opens a pull request.

Smart Dedup

Same error won't flood your repo. Fingerprinting ensures one fix per issue.

Error Dashboard

Track every error by severity. See PR stats — opened, merged, closed.

Scheduled Scans

Daily or weekly full-repo analysis. Get suggestion PRs before bugs hit production.

Secure by Default

OAuth-only. Code read on-demand, never stored. Revoke access anytime.

Multi-App

Monitor multiple apps. Each gets a unique integration ID and its own error stream.

GitHub & GitLab

Works with both. Login with either, connect repos, get fixes wherever your code lives.

5-Second Setup

One script tag. No SDK, no build config, no agents to install.

FAQ

Common questions

What is nreactive?

nreactive is a developer tool that monitors your applications for runtime errors and automatically creates AI-powered pull requests with fixes on GitHub or GitLab. You add a single script tag — nreactive handles the rest.

How does it work?

Add our integration script to your app. It captures errors, warnings, and exceptions in real-time. Our AI analyzes the error context and your source code, then opens a pull request with an intelligent fix for you to review and merge.

Is my code secure?

Yes. We only read the specific files referenced in error stack traces. Your code is processed securely, never stored permanently, and never shared. We use OAuth with minimal required permissions.

Which platforms are supported?

nreactive integrates with both GitHub and GitLab. You can login with either provider, connect your repositories, and receive fix PRs directly in your workflow.

Does it create duplicate PRs for the same error?

No. nreactive deduplicates errors using smart fingerprinting. If the same error occurs multiple times, it increments the occurrence count but only generates one fix.

What types of errors does it catch?

It captures uncaught exceptions, unhandled promise rejections, console.error calls (classified as errors), and console.warn calls (classified as suggestions). Errors are ranked by severity: Critical, Error, and Warning.

Can I schedule proactive code analysis?

Yes. Pro users can configure daily or weekly full-repo scans. The AI reviews your code for potential improvements and opens suggestion PRs proactively, not just in response to errors.

Is there a free plan?

Yes. The free plan includes 1 monitored application with up to 2 error captures per day. The Pro plan at $49/mo per application unlocks unlimited errors, automatic PRs, and scheduled code analysis.

Ship faster. Break less.

Add one script tag and let AI handle your runtime errors. Automatic pull requests with intelligent fixes.
