Sound familiar?

🚀

You shipped your app. Real people are using it.

💀

Then something breaks in your live, deployed app. 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 or create a PR." Less context switching. Less manual triage. That's Codemend.

How it works

Add a snippet. Get notified when things break, with the fix already written.

1

Add Codemend to your app

One line of HTML or a tiny npm init. 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 AnalysisClaude AI
ReadingProductList.tsx
Readingapi/products.ts
Readingtypes/product.d.ts

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

2

AI reads your code and writes the fix

When an error happens, our AI agent reads the actual source files from your GitHub repo, follows imports, checks types, and writes a fix that fits your codebase, not a generic suggestion.

Multi-turn analysis with Claude AI. Up to 8 analysis turns. Generates a diff, confidence score, and a plain-English explanation anyone can understand.

3

Get notified. Review the fix.

Get a Slack, Telegram, email, or push notification the second something breaks, with the fix context included. From there, review the fix on your dashboard, create a PR if a repo is connected, or paste the prompt into Lovable, Replit, or Cursor.

Total time to a reviewed fix can drop from hours to minutes

Connect GitHub. Unlock the full fix.

Without your source code, AI gives you a generic answer. Connect your repo and Codemend reads your actual files, so every fix references your real code, real file paths, and real line numbers.

Developers

  • Connect your repo to unlock source-aware fixes
  • AI reads your actual source files
  • Fixes reference real file paths + line numbers
  • Create a PR from the fix screen, then review and merge

Vibe Coders

Using Lovable, Replit, or Bolt? They all sync to GitHub.

  • Enable GitHub sync in your AI platform
  • Connect that repo to Codemend
  • When a fix is ready, create a PR from Codemend
  • Merge it, then the changes flow back to your platform

Site Owners

No repo? No problem. You still get:

  • Instant alerts when something breaks
  • Plain English explanation of the error
  • The exact fix, copy and paste it
  • Connect a repo later for PRs + deeper analysis

Without GitHub

Generic fix based on the error message alone

With GitHub

Precise fix referencing your actual code + PR creation from the fix screen

The old way vs. Codemend

Without Codemend

  • Users hit a bug in your live app. 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 ChatGPT, get a generic answer without your codebase context
  • 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 read your code and wrote the fix
  • Create a PR if a repo is connected, or copy the fix prompt
  • Review it quickly and decide how to ship the fix.
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, our multi-turn AI agent (Claude) reads the actual source files from your GitHub repo, it follows imports, checks types, and explores up to 8 files. 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 approve, 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. Lovable users get Lovable-specific prompts, Cursor users get a terminal command. If your platform syncs to GitHub, connect that repo and Codemend can read your actual source code and let you create pull requests from the fix screen.
How do I get notified?
Email is on by default for each project until you turn it off. You can also connect Slack, Telegram, or browser push notifications. Slack and Telegram can include direct fix actions when a repo-backed fix is available, and all channels point you back to the dashboard when you need to review more detail.
Is my code safe?
Yes. We only read your code when analyzing a specific error, we never store your full source code. Code snippets are sent to Claude AI (Anthropic) for analysis and are not used for training. All data is encrypted in transit and at rest.
How is this different from Sentry? Can I use both?
Sentry is monitoring. Codemend is fixing. Codemend explains what broke in plain English, reads your real code, and writes the fix you can apply as a PR or copy into your AI tool. If you already use Sentry, you can connect it as an advanced integration from Settings.
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 Anthropic API key and the AI fix quota is unlimited on any plan. Upgrade for higher error volume, more projects, and longer retention.
