Step 1: Describe your messaging app

Start a chat with Replit and outline the experience you’re after—real-time chat, emoji reactions, user profiles, or anything else you have in mind. Add preferences such as “use React for the front end” or “save messages,” or simply say “create a basic web chat.”

Step 2: Review and approve the plan

Replit replies with a clear build plan, file outline, and a visual design preview. Check the proposed features, refine anything that feels off, then approve the plan to start the build.

Your workspace comes to life as Replit sets everything up behind the scenes—frameworks, database, and front-end pages included. Progress updates appear in real time, and you can peek at any file while it’s created.

Step 4: Test in preview and request changes

Open the preview, send a few messages, and invite friends to try it out. If you spot an error or want a new feature—say dark mode or typing indicators—ask Replit in chat. It will update the app and automatically save checkpoints so you can roll back whenever you like.

Step 5: Publish your app and start using it today

With one click, push your chat app online and get an instant public URL. You can add a custom domain, share the link, and keep shipping updates just as easily.

Tips for building a messaging app with Replit

Start with a clear, detailed prompt

Replit does its best work when it understands what you need. Describe all the data and features you’ll need up front—like Users, Conversations, and Messages—so it can generate the matching backend properly.

Let automatic checkpoints keep you safe

Building in small steps keeps your project manageable. Replit saves checkpoints automatically, giving you a safety net as you experiment. For example, set up user registration first, then move on to messaging threads knowing you can always roll back to a stable baseline.

Test live with multiplayer sessions

Real-time collaboration isn’t just for coding—it’s perfect for uncovering bugs early. Invite teammates into the same workspace so everyone can poke at new features together. Log in as different users in separate tabs and watch messages flow between them while you build.

Protect secrets and user data from day one

Even in a prototype, protecting credentials and personal info builds trust. The built-in secrets manager keeps secret keys and environment data out of your code so your messaging app stays secure.
