Sound familiar?

🚀

You shipped your app. Users are loving it.

💀

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

🤷

Nobody tells you. No alert. No email. Users just leave.

😵

Days later you find out. You check the console. TypeError: Cannot read property 'data' of undefined.

😔

If you're a developer, you spend an hour debugging. If you're a vibe coder, you don't even know where to start. If you run a Shopify store, you just lost sales.

💸

Either way, your users already left.

✨

What if you got a Slack or Telegram message the second it happened?

"Your product list crashed. The API returned null instead of an empty array. We already wrote the fix — click here to apply it." 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, 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 integrationPro
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. 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/Cursor.

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 in one click
  • AI reads your actual source files
  • Fixes reference real file paths + line numbers
  • One-click PR creation — 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
  • We create a PR when errors are found
  • Merge it — 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 + 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 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
  • One click to create a PR or copy the fix prompt
  • 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, 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 one-click terminal command. Connect your GitHub repo (Lovable, Replit, and Bolt all sync with GitHub) and Codemend reads your actual source code for precise fixes and can create pull requests automatically.
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 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?
Sentry is an error monitoring tool built for developer teams — it shows stack traces, dashboards, and performance data. Codemend goes further: it explains what broke in plain English, writes the actual code fix, and gives you a ready-to-paste prompt for your AI coding tool. Developers can use both together — Sentry monitors, Codemend fixes.
How does the free plan work?
The Free plan is free forever — 1,000 issues/month, 15 AI fixes, 1 project. No credit card required. Upgrade anytime for more capacity and features like GitHub PRs, Sentry integration, and auto-merge.
