Replit Alternatives for Apps With Login and a Database

The Replit alternative worth moving to is the one that keeps your customers' logins and your data in an account you own. Dyad works that way. It's a free, open-source desktop app that builds your app as normal code on your computer, with the login and database in your own Supabase or Neon account. Lovable, Bolt.new and Base44 keep them on their own backends by default, the way Replit does.

Some people start looking because of the bill. Replit Agent's paid work is priced by effort: each request is priced by how complex it is, and Replit's docs give no fixed price per change. In an October r/replit thread titled "Wild swings in agent costs", one builder wrote that "my cost per minute was 4 to 5 times what I'm seeing today." But the bigger surprise comes when you try to leave.

What a Replit app leaves behind

Replit makes the first version easy because it runs every piece for you. That's also the part you're renting. Here's what Replit's own docs say about each piece:

• The code comes with you. You can download a project as a zip or turn on two-way sync with GitHub.
• The rest doesn't. When you copy a project, Replit tells you to "set up secrets, the database, and deployment configuration in the new project", because "those aren't included in the copy." Secrets are your API keys and passwords for other services.
• Your customers' logins may be Replit accounts. With Replit Auth, "your users sign in with their existing Replit accounts" on a sign-in page that's "Replit-branded." For something with its own brand identity, "especially something customer-facing or commercial," Replit itself says Clerk Auth is "the better fit." Clerk is a separate login service that gives your app its own accounts.
• Your live data sits in a separate database. Every app gets a free development database. The production one, which holds your real customers' data, is created when you publish and billed by usage through Neon, a hosted database company.

None of that is unusual for a hosted platform. But when you leave, only the code downloads. You move the data by hand. And if you used Replit Auth, your customers' logins stay behind, because they're Replit accounts.

Replit alternatives compared

Each tool counts its free plan in a different unit (credits, tokens, message credits), so you can't line them up as totals. The Base44 price is for annual billing; the others are monthly prices.

Cursor and Claude Code show up on a lot of Replit alternative lists too, but they aren't in this table. They're coding tools for developers, not app builders for the rest of us, and a Dyad app opens in either one whenever you want to hand it off.

Dyad

Dyad is a free, open-source AI app builder that runs on your Mac or Windows computer (Linux builds are experimental). You describe the app in a chat and watch it come together in a live preview. Every app is a normal Git repo on your disk, so there's no export step, and you can open it in VS Code or Cursor whenever you want.

I'm Will Chen, and I built Dyad after I tried one of the popular cloud app builders, pulled the app down to debug it in Cursor, and it just didn't work. So Dyad is for people who aren't developers but want to own what they make. Your code is your code, and it's all on your computer.

Three worries come up about Dyad. Here's what's true for each.

"You'd have to set up the login and database yourself." You don't. When your app needs accounts, you sign in to your Supabase account from inside Dyad, or let Dyad create a new Supabase project for you. Dyad's AI then writes the login page, the sign-in handling and the tables. In Agent mode, Dyad asks for your approval by default before it runs SQL that creates or changes a table. Dyad also tells the AI to turn on row level security for every table. That's a database rule that limits which rows each person can see. For Next.js and Vite apps you can pick Neon instead, and Dyad creates the Neon project with Neon Auth built in. Yes, it's a separate account, and that's the point: your customers' accounts and your data live in a project you own. The Supabase guide walks through it.

"You need your own API key." You don't need one to start. The setup screen offers a Dyad Pro trial, free models through OpenRouter, and your ChatGPT subscription. You can also bring an API key or run a free local model through Ollama or LM Studio.

"It's a desktop install with Node.js." It is a desktop app, but Dyad installs the Node.js it needs by itself on Mac and Windows. Linux users install Node.js themselves.

Dyad doesn't host apps. When you're ready to go live, the Publish tab connects your GitHub account and then deploys to Vercel, so your app runs on your own Vercel account. The free Vercel guide covers that part.

As for the bill: the app itself is free, and with your own API key you pay your AI provider directly, or nothing with a local model. Dyad Pro is $20 a month for 200 AI credits and the Pro Agent, and it's optional. More than 21,900 people have starred Dyad on GitHub, and builders leave reviews on Product Hunt.

Lovable

Lovable is a browser-based AI app builder. Its backend, Lovable Cloud, gives each app a database, authentication, storage and server functions on Lovable's side. Git sync is available on every plan, including Free. The free plan gives 5 credits a day, up to 30 a month, and Pro is $25 a month for 100 credits. You'll need a paid plan to download the code or edit it directly in Lovable.

Bolt.new

Bolt.new builds apps in the browser, and "every Bolt project can have a built-in database" with tables, authentication, file storage and server functions. On Pro and Teams you can use your own Supabase instead, but Bolt's Supabase guide says to select it when you start a new project and that switching later "requires extra steps." The free plan has a 300K-token daily limit and 1M tokens a month. Pro is $25 a month.

Base44

Base44 is a no-code AI app builder that Wix bought in June 2025. Its free plan gives 25 message credits a month, and Starter is $16 a month billed annually. Two-way GitHub sync starts at the Builder plan, and the synced code still runs on Base44: Base44's docs have you log in with its command-line tool and run its backend, and your data stays in Base44's built-in database.

Moving from Replit to Dyad

Here's where each Replit piece goes when you move a Replit app to Dyad.

1. Get your code. Download the project as a zip from Replit, or sync it to a GitHub repo.
2. Write down your secrets. List the API keys and passwords in Replit's Secrets tool, and the settings in its Configurations section, like feature flags and service URLs, including any published-app values. Your published app keeps its own set too, under Production app secrets in its Publishing settings. None of them come with the code.
3. Start the app in Dyad. Describe the app in a new chat, or import the code from a folder or GitHub (app import is experimental and works for JavaScript apps only; for a Python or Ruby app, describe it in a new chat instead) and ask Dyad's AI to replace the Replit-only parts.
4. Connect Supabase or Neon. Let Dyad's AI create the login and the tables. Put each secret where the code that reads it runs. Secrets for edge functions (small pieces of server code that Supabase runs for your app) go in Supabase's Edge Function secrets now, and the rest go in Vercel in step 6. Move any uploaded files (Replit's App Storage) into Supabase Storage.
5. Move the data. Replit's database is PostgreSQL, so a standard dump and restore moves it. Dump the production database, which your published app uses, not the development one the Project Editor shows. First pause new orders and sign-ups on your live Replit app until your Dyad app goes live, or anything saved after the dump is lost. On Neon, restore the dump into your production branch, not the development branch Dyad recommends building on, because Dyad's Migrate to Production copies only the tables' structure, not the rows. Supabase and Neon both publish guides for moving data from another Postgres database with pg_dump. For a few small tables, export them as CSV files and import them in Supabase's Table Editor.
6. Go live. Publish through GitHub and Vercel, and add your app's other secrets to the Vercel project's environment variables. Then, in your Supabase project, set the Site URL to your live address and add it to the redirect URLs. Supabase uses the Site URL as the default address for sign-up and password reset email links, and it starts as http://localhost:3000. Until you change it, those links can send your customers to their own computer, where they don't load.

One thing to plan for: your customers' logins. With Replit Auth, they signed in with Replit accounts. With Replit's Clerk Auth, Replit runs the Clerk setup for you, with no Clerk account of your own. Either way, after the move your customers create a new login on your app's own sign-in page. In Supabase Auth, each new login gets its own user ID, so you'll need to link any data tied to a customer's old login, like their orders or saved items, to their new one. From then on, those logins live in your own Supabase or Neon project. For a side-by-side of building the same app in each tool, see Dyad vs Bolt vs Replit.

FAQ

Where will your app live?

If you're about to move off Replit, decide first where your customers' accounts and data should live, and then pick the builder. If you'd like them in your own Supabase or Neon project, with the app on your own computer, try Dyad on a copy of your app first. What's the one piece of your Replit app you'd worry about moving?
