Codemend
Live error fixes for vibe coders, founders, and developers

Your live app broke.
Codemend gives you the fix.

Codemend catches real production errors, explains them in plain English, and gives you a ready-to-use fix prompt, GitHub PR, or alert.

Built for Lovable, Replit, Bolt, v0, Cursor, and GitHub-backed apps — so you know what broke and exactly what to paste, apply, or merge.

Start monitoring free

Free: 1,000 errors/month, 10 AI fixes. No credit card required.

Not code cleanup

Codemend watches what actually breaks.

Code cleanup tools scan a project before launch. Codemend monitors your live app after launch, catches real user-facing failures, and helps repair the broken code path.

Paste into your AI builder

Lovable, Replit, Bolt, v0, Cursor, Claude, or ChatGPT.

Open a GitHub PR

For synced repos and developer workflows.

Send the fix alert

Slack, Telegram, email, push, or webhook.

Know the second it breaks

Get an alert with the error explained and the fix included. Paste it into your AI builder, create a PR, or hand it to your developer.

Sound familiar?

🚀

You shipped your app. Real people are using it.

💀

Then something breaks in production. A button crashes. A page goes blank.

📲

Nobody tells you. Friends screenshot you the errors. You're pasting them into Claude trying to figure out what happened.

😵

Someone suggests setting up Sentry. You try. It takes longer than expected. By then users have already left.

😔

If you're a developer, you've lost an hour debugging. If you're a vibe coder, you don't know where to start. If you're a solo founder, you're just hoping nobody noticed.

💸

Either way, your users already left.

✨

What if the fix just arrived in your Telegram the moment it broke?

"Your checkout crashed. The submit handler was never defined. Here's the fix — paste it into Lovable, send it to Cursor, or merge the PR." No Sentry setup. No debugging. No context switching. That's Codemend.

How it works

Add a snippet. Get notified when things break — with a fix path that matches how you build.

1

Add Codemend to your app

One line of HTML, an npm package, or connect Sentry — pick whatever fits your stack. Takes under a minute.

<script src="https://codemend.ai/s.js" data-key="ah_...">
npm install codemend
Browser script1 line
npm SDK3 lines
Sentry integrationAll plans
AI Agent AnalysisAI analysis
ReadingProductList.tsx
Readingapi/products.ts
Readingtypes/product.d.ts

Root cause: API returns null on empty result. Fix: add fallback || []

2

AI reads the error and writes the fix

When an error happens, Codemend uses the stack trace, runtime context, source maps, project memory, and your connected repo when available to write a fix that matches how your app is built.

You get a plain-English explanation, a confidence score, and a fix formatted for your workflow: pasteable prompt, suggested diff, or pull request.

3

Get notified. Apply the fix.

Get a Slack, Telegram, email, or push notification the second something breaks — with the fix prompt included. Review on your dashboard, create a PR with one click, or paste the fix into Lovable, Replit, Bolt, v0, or Cursor.

Pick the fix path that matches how you build.

Vibe coders can paste the fix into their builder. Developers can open a GitHub PR. Site owners can forward the alert to whoever owns the site.

With GitHub

Precise fix referencing your actual code plus one-click PR

The old way vs. Codemend

Without Codemend

  • Users hit a bug in production. They leave. They don't tell you.
  • No alerts, no context — you don't know your app is broken
  • Hours later you find out. Dig through logs, reproduce locally, trace the stack.
  • Paste the error into an AI chat — then spend time explaining your app and hoping the answer fits
  • Manually write the fix, test it, deploy it. Repeat tomorrow.
Slow. Manual. Reactive.

With Codemend

  • User hits a bug — you get a Slack/Telegram/email alert instantly
  • Read what broke in plain English, no stack traces
  • AI already analyzed the failure and wrote the fix
  • Copy the fix prompt into your AI builder, or create a GitHub PR when your repo is connected
  • Apply it. Users never knew anything broke.
Instant alerts. AI-powered fixes. Ship faster.

Frequently asked questions

What frameworks and platforms does Codemend support?
Codemend works with any web app (React, Next.js, Vue, Svelte, Angular, vanilla JS), Node.js backends (Express, Fastify, etc.), AI coding platforms (Lovable, Replit, Bolt, v0, Softgen, Tempo, Base44, Firebase Studio), and website builders that support custom code (Wix, Squarespace, Webflow, Framer, Shopify, WordPress). If your site runs JavaScript, Codemend can monitor it.
Do I need a GitHub account?
No — you can sign up with just an email and password. You'll get error alerts and AI explanations, and can copy-paste fixes manually. If you want automatic pull requests, connect your GitHub account anytime from Settings.
How does the AI analysis work?
When an error occurs, Codemend analyzes the stack trace, runtime context, source maps, project memory, and connected repo when available. It generates a plain-English explanation, root cause, suggested code diff, confidence score, and a ready-to-paste fix prompt for your AI coding tool.
Does Codemend change my code without asking?
Never. Codemend suggests fixes and shows you the exact code changes. You review everything on your dashboard. If you connect GitHub and approve the fix, it creates a pull request — you still merge it yourself.
What is the CLI tool?
Install with npx codemend-cli. Use "codemend apply <error-id>" to fetch an AI-generated fix and apply it directly to your local files. Use "codemend show <error-id>" to see the fix without applying. Great for developers who prefer terminal workflows.
How does the n8n integration work?
Install the n8n-nodes-codemend community node in your n8n instance. It gives you three operations: Send Error (forward errors from any trigger), Check Status (poll until analysis completes), and Get Fix (retrieve the AI fix). Build workflows like: Error Trigger → Codemend → Slack/Email.
What if I built my app with Lovable, Replit, or another AI tool?
Perfect — Codemend is designed for this. When an error happens, you get a ready-to-paste fix prompt for your specific tool. Paste it into Lovable, Replit, Bolt, v0, Cursor, Claude, or ChatGPT. If your builder syncs to GitHub, connect that repo later for deeper source-aware fixes and pull requests.
How do I get notified?
Email is automatic for all users. Connect Slack (one-click OAuth), Telegram (click "Connect Telegram" in Alerts settings, then tap Start in the Codemend bot), or enable browser push notifications. All channels include the fix prompt so you can act immediately without opening the dashboard.
Is my code safe?
Yes. We only read connected repo files when analyzing a specific error — we never store your full source code. Code snippets are sent to your selected AI provider for analysis and are not used for training by Codemend. All data is encrypted in transit and at rest.
How is this different from Sentry? Can I use both?
Sentry is an error monitoring tool — it captures stack traces, shows dashboards, and tracks performance. Codemend is the fix layer on top: it explains what broke in plain English and gives you the fix as a prompt, diff, PR, alert, or webhook. They do different things and work great together. Connect your Sentry account from your project Settings in one click — errors Sentry captures will automatically flow into Codemend for AI analysis. Nothing changes in your existing Sentry setup.
How does the free plan work?
The Free plan is free forever — 1,000 errors/month, 10 AI fixes, 1 project. No credit card required. Add your own OpenAI or Anthropic API key and the AI fix quota is unlimited on any plan. Upgrade for higher error volume, more projects, and longer retention.
