Add AI support to your Replit app
Replit is a cloud IDE that also hosts your app — you write code in the browser (often with Replit's AI Agent) and it runs and deploys from the same environment, no separate hosting setup required.
Start free trialWhy a Replit app needs support anyway
Replit gets a working app online fast, including the backend. But 'online' quickly turns into 'people are using it and emailing me questions' — and Replit's Agent doesn't handle your support inbox.
Add support to your Replit app
Open your entry HTML file
For a static or frontend-only Repl, that’s index.html. For a Repl with a backend (Express, Flask, etc.) serving a template, find the base HTML template it renders.
Paste the script tag before </body>
You can type this directly in the Replit file editor, or ask Replit’s Agent: "Add this script tag right before the closing body tag in our main HTML file."
<script src="https://app.resply.io/widget.js" data-org-id="YOUR_ORG_ID" async></script>Your Repl updates live
Replit apps run continuously, so the widget appears as soon as you save — no separate deploy step, no rebuild.
The questions you'll get asked
Answer each once in your docs, and Resply handles it automatically from then on.
FAQ
Does this work with Replit’s Always On / deployments?
Yes — it’s a script tag in your served HTML, so it works identically whether your Repl runs on the free tier, Always On, or a Replit Deployment.
What if my Repl is a backend API with no HTML?
If your Repl only serves an API with no frontend, add the widget to whatever separate frontend actually shows your UI to users — the widget needs a page to render on.
