Base44 vs Replit, and what your app needs once it’s live
Base44 and Replit both turn a chat into a working, hosted app, and they suit different founders. Base44 suits the founder who never wants to see code. It builds the pages, database, sign-in and hosting on its own backend, and bills two kinds of credit, one for building and one for what the live app does. Replit suits the founder who wants the code within reach. Agent works in a cloud workspace where you can open every file, and its paid work is billed by effort, from the same credit your hosting and database draw on. Neither comes with a support chat ready for the people who use your app. Deacon, an AI customer support agent, answers them from your own docs and shows you what they want built next. It has a free plan with no card.

How you build on Base44 and on Replit
On Base44, you describe the app in the AI chat and Base44 builds all of it, from the pages to the data model, sign-in and hosting. Discuss mode talks an idea through without changing the app, Edit mode lets you point at the element you want changed, and the visual editor handles text and layout by hand. Editing the source in the Code tab starts on Starter, and backend functions, for logic that runs on the server, start on Builder.
On Replit, you describe the app to Agent in the Project Editor and watch it build in a live preview. Agent is one tool in a full cloud workspace, with a file tree, a code editor and a shell beside it. Plan Mode turns an idea into a task list you approve before any code changes, and Full build lets Agent work with more autonomy. Both need Core, so the free Starter plan builds with Lite build, Replit’s fast, focused mode for quick edits and targeted changes. Agent also makes mobile apps, and from Core, slides, data visualisations and other kinds of project.
So they differ mainly in how close you work to the code. Base44 treats it as something you might open one day. Replit treats it as the thing you’re making, with Agent doing most of the typing.
What Base44 and Replit cost, and what their credits pay for
Base44 bills your prompts and your running app from two fixed allowances
Message credits pay for prompts in the AI chat, from about 0.5 for a small text change to 3 or 4 for a change across the whole app, and about 0.3 for a message in Discuss mode. Integration credits pay for Base44’s built-in services when your live app uses them, about 1 for an email, an upload or an LLM call on the Automatic model, and from about 3 for each reply from an in-app agent. Reading and writing your database costs neither. Both kinds reset monthly, and what you don’t use expires. At zero, anything that needs credits pauses until your reset, and Base44’s way round that is to upgrade.
Replit gives Agent a free allowance, then bills paid work by the checkpoint
On Core, $20 of monthly credit pays for Agent’s paid work, publishing, network transfer and your production database, and Free Mode covers everyday building on top, up to 30 hours of chat. Paid work runs in Power or Max mode, and Replit asks before it starts. Each request becomes one checkpoint when it’s finished, so a bug fix typically costs less than a whole feature. Core’s credit doesn’t roll over, and Pro’s rolls over for two months. Past it you pay as you go, or buy a credit pack from $100, unless a budget you’ve set suspends usage-based services until the next cycle.
The figures in these cards are from base44.com/pricing, Base44’s credits guide, replit.com/pricing, Replit’s AI billing guide and its guide to managing spend, read on 27 September 2026. Base44 pricing and Replit pricing go through each plan in more detail.
Both entry plans cost $20 on monthly billing. Base44’s Starter is $16 a month billed yearly, and Replit’s Core is $18. Above Starter, Base44 has three more plans you can buy directly, Builder at $50 a month or $40 billed yearly, Pro at $100 or $80 and Elite from $200 or $160, with credits rising to 1,200 message and 50,000 integration credits a month at Elite’s starting price. Replit has one, Pro, at $100 a month or $90 billed yearly, for at least $100 of credit that rolls over, up to 15 collaborators and 10 Agent tasks running at once. Neither charges per seat. Everyone in a Base44 workspace draws on the same credits, and Replit’s Core takes up to 5 collaborators.
The same $20 buys different things. On Base44 it buys 100 message credits, which by Base44’s own rough rates is about 100 small feature changes, and 2,000 integration credits for your live app. On Replit it buys $20 of credit, spent in dollars on Agent’s paid work and on keeping your app running, with Free Mode’s allowance for everyday building on top.
The bills differ most on hosting. Base44’s pricing lists no charge for hosting, and its credits guide says reading and writing your database costs no credits. Replit bills a production database for every hour it’s active, at $0.16 an hour, and for storage at $0.35 a GiB a month. By our sums, a database kept busy 4 hours a day costs about $19 a month in compute, nearly all of Core’s $20 before Agent has done any paid work. A quiet app costs far less, because the database suspends after 5 minutes without a request.

Base44’s prices come from base44.com/pricing and its plans guide, and Replit’s from replit.com/pricing and its guides to Starter, Core and Pro, all read on 27 September 2026. Base44’s pricing page opens on yearly prices and draws the monthly ones in the browser, so those come from the price data the page loads. The docs behind the other rows are listed at the end. Replit’s database limits and Base44’s analytics history were read again on 13 October 2026.
Where your app, data and code end up
Both host your app, at an address of theirs to begin with. A Base44 app is live at a base44.app address from the moment you create it, and you can rename that address for free. Your own domain connects from Starter, with 301 redirects for pages you move. A Replit app gets a replit.app address when you publish it, and once it’s live, the Domains tab buys a domain or connects one you own, for whatever your domain provider charges. On the free Starter plan, the one published app goes down after 30 days and has to be republished.
They differ most on your data. Base44 builds a database into every app and keeps the data model, which it calls entities, managed in Base44. Even with GitHub sync the entities stay out of your repository, though each table on the Data page has an Export option and deleted records can be restored for 30 days. Replit gives your app a managed PostgreSQL database. The development database you build against is free, with 20 GiB of storage per app, or 50 GiB on Pro. The production one is billed by use and holds up to 100 GiB on a paid plan, or 1 GiB on the free Starter plan. Pro stretches the window for restoring a database to 28 days, from the standard 7.
The code sits closer to hand on Replit. Base44 apps are React apps built with Vite. From Starter you can edit any file in the Code tab, and from Builder, two-way GitHub sync keeps a repository of your own up to date and lets you work on the code locally. On Replit, the code is what you see as you build. You can open any file, run commands in the shell, push to GitHub from the Git pane and download the whole project as a zip.
What each gives you after launch
Base44 counts traffic from the first publish, and keeps 60 days of it
Base44’s analytics shows visits, unique visitors and who’s on the app right now, with the pages, countries, sources and devices behind them. You describe custom events such as sign-ups to the AI chat, 3 of them on Free and as many as you like from Starter. History lasts 60 days on every plan, though Free shows only the last 7, and Base44 points you to its Analytics API to keep anything older. For questions, you set up an in-app agent. It talks only to signed-in users unless you allow anonymous access, and each conversation shows in the Users tab of the Agents dashboard.
Replit counts visitors for up to 30 days, and collects feedback
Replit’s Growth pane shows visitors, top pages, referrers, countries, browsers and devices once you turn on Enable analytics and publish, over ranges from six hours to 30 days. On a paid plan, Agent adds custom events such as completed sign-ups and answers questions about the numbers. A feedback widget lets visitors sign in and report a problem or suggest a change, which lands in your Inbox for Agent to work on. For questions, Replit has no ready-made chat for your visitors. You ask Agent to build one and pay for its model, with your own key or, from Core, through Replit AI Integrations.
These cards come from Base44’s guide to app analytics, its guide to in-app agents, Replit’s guide to Project Analytics and its feedback widget guide, read on 27 September 2026. Base44’s analytics history was read again on 13 October 2026.
So both count your traffic, and Replit also collects the reports visitors choose to send. Neither answers a visitor’s question the moment it’s asked unless you build a chat and pay for its replies, and neither sums up what all those visitors wanted. Those unanswered questions pile up in the first weeks after launch, and answering them is Deacon’s job.
Where Deacon fits on a Base44 or Replit app
On Base44 or Replit, what you build next is whatever you type into the chat, so after launch you have to work out what to ask for. The people using your app know, if they have somewhere to say it. Put Deacon on the app and they’ll ask its chat, which answers them in seconds from your own docs. Each question also goes into Topics, which put the ones that ask the same thing together and count the people behind each.
Read What they ask you to build, on Analytics › Widget, before you write your next prompt. It quotes recent feature asks in people’s own words, with asks about the same thing grouped under one topic and the most asked first. That’s a list to take straight to Base44’s chat or Replit’s Agent. A topic led by bug reports is marked as one too, so a bug that has caught several people stands out from the rest.
If you keep the code in reach, on Replit or through Base44’s GitHub sync on Builder, connect Claude Code or another coding agent to Deacon’s MCP server. It reads those bug reports, and the JavaScript errors from your live pages, before it goes looking for the cause.
People who hit an error in a new app are better at showing it than describing it. They can drop a screenshot into Deacon’s chat, and Deacon reads what’s on it, error message and all, before it answers.
If your docs have nothing on a question, Deacon tells the visitor so instead of guessing and asks for their email, and the question waits for you beside an Answer this button. Write the answer, even as rough notes, and press Save. Deacon files it where it belongs in your help document, asks itself the visitor’s question again to show you what it would now say, and lists any other open questions your answer covers. So the more you answer, the less there is for you to answer next week.
Deacon’s answers come out of its own plan, so a launch week spends none of Base44’s integration credits or Replit’s credit, and nobody has to sign in before they ask. A request for a person shows in the dashboard straight away, or reaches you by email a few minutes later if you’re away. With human handoff, your reply from the dashboard lands in their chat, and the chat is kept open for three days while they wait on you.
It takes one script tag on either builder. Install hands you a prompt for Base44’s AI chat or Replit’s Agent, which adds the tag and, when your app has logins, passes Deacon your users’ details. On Base44, the tag goes in your app’s index.html, which Base44’s search guide names as the place for third-party scripts. The AI chat takes the prompt on any Base44 plan, and from Starter you can paste the tag in the Code tab yourself. On Replit, paste the prompt into the Agent chat and Agent puts the tag on every page. Then republish, because changes in the workspace don’t reach the live app until you do. List your base44.app or replit.app address, or your own domain, in Deacon’s allowed domains. Deacon and Base44 and Deacon and Replit have every step.
Base44 or Replit, by situation
Pick Base44 if you want a working app without ever opening the code. The database, sign-in, hosting and analytics come with the first prompt, reading and writing data costs no credits, and an in-app agent can create and update records for your users. Your own domain comes with Starter, at $16 a month billed yearly, and your bill stays fixed, because the credits stop at zero rather than running on.
Pick Replit if you want the code in front of you from day one, or more than a web app. The files, the shell and Git sit beside Agent, Free Mode covers everyday building, and the same workspace makes mobile apps and runs scheduled jobs. Hosting and the database are billed by use, and Core carries on at pay-as-you-go rates when its credit runs out, so a launch-week spike doesn’t stop your app. Set a budget if you’d rather it did.
If you’d rather write the code yourself, in an editor on your own machine, Cursor alternatives is the place to start, and Lovable vs Claude Code sets a builder beside a coding agent. Whichever you pick, Deacon goes on with one tag the day real people start using the app.
