Launch Checklist · Replit Agent

Launching a Replit Agent app? Check these before you hit Publish.

Replit hosting makes shipping trivially easy. Easy hosting is not the same as production hardening.

Get my checklist

Replit Agent apps have a specific advantage and a specific risk: hosting is built in, so there is no separate deploy step to forget. The risk is that the same ease means fewer natural checkpoints where someone reviews the app before it goes live, on most stacks, the deploy step forces a pause; on Replit, "Publish" is one click from "still a work in progress."

The items below are the ones most commonly missing on Replit Agent apps specifically, based on what shows up when Replit-hosted stacks run through the Stack Grader.

Replit Agent-specific

What gets missed on Replit Agent apps.

Replit Secrets vs. hardcoded values

Replit Agent sometimes hardcodes a value during generation that should live in Replit's Secrets pane. Grep the codebase for anything that looks like a key before publishing.

Always-on vs. sleeping deployments

A Repl on the free tier sleeps after inactivity, meaning the first real user hits a slow cold start. Confirm your deployment tier matches your expected traffic pattern.

Database choice under load

The default Replit database is fine for a prototype. Verify it is the right choice once you expect concurrent real users, not just your own testing.

FAQ

Common questions.

Is Replit good enough to host a real product?

For early-stage and low-to-moderate traffic products, yes, with the always-on/deployment tier set correctly and the standard production checklist (rate limiting, backups, monitoring) applied. It is not a reason to skip the checklist, just a different hosting choice.

What is the most common mistake in Replit Agent launches?

Publishing on a sleeping (non-always-on) deployment tier and not realizing the first user of the day hits a slow cold start, which looks like a broken app rather than a config choice.

Other stacks

Building on something else?

Lovable
Lovable ships a working app fast. "Working" and "production-ready" are not the same checklist.
Bolt.new
Bolt.new is built for speed of iteration. The checklist below is the speed-of-iteration tax you pay back before real users show up.
v0 (Vercel)
v0 is excellent at UI. Production readiness lives in the layers v0 was never asked to think about.
Next.js (custom)
Hand-rolled means nothing is generated for you, including the parts people forget on purpose-built apps too.
React Native / Expo
Mobile has a review gate a website does not. Miss one of these and you lose a week to a rejection, not a bug report.
Flutter
One codebase, two review processes with different rules. Both need a separate pass.
WordPress
The most-targeted CMS on the internet needs the most deliberate security pass, not the least.
Shopify
Shopify handles the hard infrastructure. Your checklist is everything layered on top of it.
Webflow
Webflow removes the build step. It does not remove the need to check your own configuration.
Custom / other stack
The categories that matter do not change based on your framework. The specific implementation does.
Still choosing

Head to head with the alternatives.

Lovable vs Replit
Lovable and Replit both let you build an app by prompting an AI agent, but they diverge on where the app ends up living. Lovable generates a web app with Supabase and syncs to GitHub, so you own the code and host it anywhere. Replit's Agent builds inside Replit itself, with hosting, a database, and deployment already part of the platform, no separate host to pick.
