Base44 and Replit got the expense totals right in our 4 September 2026 test. Replit displayed the wrong split size. After the build, Base44 keeps more services together. Replit gives you more control over the code and runtime.
The proof
Look at what each produced.
The same expenses. The same correct balances. Matches your answers
A trip splitter for Ana, Ben, Cass and Dev. Five expenses totalled $857.55. We calculated the answer before testing either app.
Base4416s clip
Every figure matched the answer we worked out.
The balances totalled $0.00 and the app showed three payments. It assigned the leftover cent as the brief required.
Replit15s clip
The three payments matched Base44’s.
Dev pays Ana $162.48. Cass pays Ana $117.54 and Ben $30.30. The app labelled each balance as money owed or money coming back.
Limit of this test. This checks one set of expenses against our calculation. It doesn’t establish that every possible split is correct.
The labels didn’t agree with the same expenses. Matches your answers
The petrol was split three ways. The kayak was split two ways. Both trips had four people.
Base4412s clip
Each row showed the number sharing that expense.
The kayak said split 2. The petrol said split 3. The other three expenses said split 4.
Replit12s clip
Every badge showed the trip’s four people.
The kayak badge said 4 beside a line saying For 2 people. Petrol showed 4 beside For 3 people. Those labels contradicted each other.
Limit of this test. Replit’s split-size badge was wrong on two rows. The calculations and payment amounts were still correct.

Our reading of the evidence
Choose how you want to run the app.
Base44
For teams that want app operations built in.
Base44 includes email, record-level permissions and a visual workflow builder.
The team can set those rules inside the platform.
The catch: Exported code still depends on Base44’s data, sign-in and hosting services.
Choose Replit instead when its documented language and backend options fit the project.
What each pitch leaves out: Base44 keeps the platform your app runs on, and Replit leaves the rest for you to connect.
Base44
A no-code platform where the app you describe arrives with its own back office. The database, the logins, the mailer, the model calls and the automations are Base44's, already paid for inside the plan.
Sold as: everything built in, no coding requiredBuilt for: people who want the app to run itself once it exists
What the pitch leaves out
The back office is what keeps you on Base44. Base44 hosts single-page apps only. Base44’s docs rule out server-side rendering. The stack is React on Vite with Deno functions. Eject hands you the code and an empty database, under a new app id.
Fine while you stay on the platform. If the app must run elsewhere, plan to move the data and replace the services it uses.
What comes built in
The back office includes a document database, app-user sign-in, file storage and hosting on every plan. Backend functions and Workflows require Builder or higher. Built-in email and model calls use the plan’s allowances. Base44 also documents row-level and field-level data rules, session recordings and Superagents. Check the service limits for each.
What you connect yourself
SMS through Twilio, on an account you bring. The 76-connector catalog and two-way GitHub sync, both from the Builder plan at $50 a month. Anything outside the catalog goes through Zapier or an OpenAPI spec you supply. A custom domain starts at $20 a month, and the free plan's app sits on a base44.app address.
Replit
A cloud computer with an AI agent. Replit builds the app, and underneath sits a shell, project imports, Postgres you can reach with a connection string and hosting with a published rate card. Check the exact language and framework you need.
Sold as: describe it, and it runs on a server you can log intoBuilt for: builders who will want the machine, not just the app
What the pitch leaves out
What the app does after launch is yours to assemble. Our dated record lists no native mailer, app data permission rules or session replay. A built-in visual workflow editor remains unconfirmed. Replit’s comparison page directs readers to n8n for visual workflows.
Fine if the app is the product and you’ll connect the rest yourself. If you need follow-ups inside the platform, check Base44’s documented workflow controls and test the required steps.
What comes built in
Replit includes a shell, a free editor on every plan, managed PostgreSQL with 20GB an app and Git. Running any language or framework remains unconfirmed. Hours-long unattended Agent runs remain unconfirmed too. Agent 3 tests what it built in a real browser and picks from 13 models on a paid plan. Four ways to publish, each with its price on the page. A native Mac and Windows app.
What you connect yourself
Email uses a mail service you connect. Most of the 450-plus connector directory needs Core at $20 a month. Replit-managed model credentials require paid access; Pro and Enterprise admins must enable them. Starter can use your own provider key, with separate provider billing. The free plan’s published app link goes down after 30 days.

Base44’s and Replit’s price lists have a $0, a $20 and a $100 tier. Base44 runs two meters that don’t mix, one for building and one for what the live app does, and folds hosting, the mailer and the model calls into the tier. Replit runs one, and everything the app serves is billed on top of it.
What raises the price on each plan, what each free tier holds back, and what you can take with you if you leave.
Question
Base44
Replit
What makes the price go up
Two things, counted apart. Building spends message credits; what your users do spends integration credits. Run out of either and you move up a tier or top up.
One pool, then usage. Agent work bills by effort per checkpoint, and the published app is billed again for compute, requests and storage.
What the free tier holds back
Pace. 25 build messages a month, and no more than 5 in a day, so a long session waits until tomorrow. The published app itself stays up.
Permanence. One published app, and its link goes down after 30 days. Third-party connectors wait for Core.
What you can take with you
Code and separate data exports. Eject clones the project and schemas into an empty copy. Exporting collection records to CSV is separate. Two-way GitHub sync waits for Builder at $50.
Both. A zip from the file tree on any plan, git history included, and the database is standard PostgreSQL you can dump through a connection string.
What’s the bill at your stage?
The list prices match, so the question is what each one still bills you for. Base44 sells a tier that already contains the mailer, the model calls and the hosting. Replit sells a tier plus a meter. The plans below are the vendors’ own price lists. Their numbers, our matching.

Base44 generates images, video and speech using integration credits. The recorded free allowance is 100 credits a month.
SEO controls & social previews(Base44 writes the canonicals, the sitemap and robots.txt itself, but holds the score down until a custom domain is connected, which starts at $20 a month. Replit's SEO agent needs a published public deployment)

✓
In Base44, set search metadata and social previews; the platform creates canonical links, a sitemap and robots.txt. A custom domain is paid and affects the SEO score.
Ask Agent to add titles, descriptions and social-sharing metadata, and review the published app with Replit’s SEO tools. SEO ratings require publicly accessible deployments and don't guarantee rankings.

Base44: Team members share credits, with spending shown for each person. Per-person spending caps require Enterprise.
Official desktop appEarlier comparison note · Original check 2026-09-04. (Base44 ships iOS and Android and sends desktop-only work back to a browser. What you install for Base44 is Base44’s CLI.

Per-record and per-field permission rules on the data(Base44's row-level rules take a condition per operation, with field-level read and write on top. Replit's own security post says row-level security works best paired with a backend doing the authorization checks rather than standing as the only layer, and Replit describes no built-in way to set per-record rules. Replit’s database is standard Postgres, so the policies would be yours to write)

In Base44, define row-level and field-level security rules on entities to control which records and fields a user may access. Apply and test rules for the actual user roles. These are data rules rather than merely hiding interface elements.

Requirement: Say who can read or change a given row, and a given field, as a rule rather than as code.
Control whether your work trains the models(Base44's terms reserve the right to train on customer data, and the opt-out is Enterprise, where it’s the default. On Replit the control is visibility: private projects are excluded, and Pro and Enterprise are excluded by contract)

For Base44, the terms allow training on customer data outside the Enterprise opt-out. Enterprise excludes that data by default.
Replit: Private projects are excluded from training. Pro and Enterprise also have contractual exclusions; project visibility is the control described here.
We pasted the same trip-splitter brief into Base44 and Replit on 4 September 2026. We entered five expenses totalling $857.55 and checked the balances against our calculation. We also compared the labels on each expense.
What we didn’t establish
We checked five expenses and their displayed split sizes. Other amounts, later edits and ongoing running costs aren’t tested in these clips. Correct balances didn’t prevent Replit from displaying two wrong labels.
Recordings and vendor documentation
The trip-splitter recordings show totals, payment instructions and expense labels. The workflow, email and permission comparisons use vendor documentation. A correct calculation doesn’t establish those platform features. A matching checkmark doesn’t mean Base44 and Replit implement the capability the same way.
Each one is missing the thing the other sells. Everything else is detail.
Base44’s
Your app runs on Base44’s platform, and you can’t swap that platform.
Base44’s five confirmed limitations are: no shell, one stack, single-page apps only
with server rendering ruled out, no pointing at a backend you run, and a builder that stops when you close the tab.
Eject hands you the code under a new app id and an empty database.
This fits if you plan to keep the app on Base44. If it has to run somewhere else one day,
you’ll need to move the data and replace the services it uses.
Replit’s
Everything after launch is yours to assemble.
The dated record lists no native mailer, app data permission rules or session replay. A built-in visual workflow editor remains unconfirmed. Replit’s security post puts access checks in your app’s code, and Replit’s
comparison page directs readers to n8n for visual workflow editing.
fine if the app is the product and you’ll connect the rest yourself. If several operations must stay inside one platform, check Base44’s documented controls against that list.
Four smaller ones, worth knowing before you pay
Base44’s published training opt-out is limited to Enterprise. Base44’s terms reserve the right to train on customer data, and Base44 documents no self-serve opt-out below Enterprise, where being opted out is the default.
Base44’s free plan has daily and monthly limits. 25 build messages a month and no more than 5 in one day, so a long session stops and waits.
Replit gives you a choice of sign-in services, while Base44 includes app-user sign-in in its backend. Replit Auth uses Replit accounts. Clerk Auth gives the app independent accounts, and Replit provisions it without a separate Clerk account. Configure the app’s access rules for either method.
Replit’s ISO 27001 claim applies to Replit’s cloud provider. SOC 2 Type 2 is Replit’s. Replit’s docs claim ISO 27001 for the cloud platform. Base44 claims SOC 2 Type 2 and ISO 27001 for Base44.
Your first move
Base44 and Replit are free to start, and the free tiers stop in different places
Base44 counts two allowances and Replit bills hosting past the plan, so both bills change with use, and
neither is a number we can fix here. Every link here opens the vendor’s own live page and you read today’s numbers. The two
“Start building free” buttons are affiliate links (disclosed below).
From readers
Both got a hard calculation right in one sitting. The tenth change is the one we can’t run
Readers who kept editing a Base44 or Replit app past the first build know which one stayed easy. Say what you asked for on the tenth change, and what it did to the thing that already worked.
