1. WebTwizz: best for building a real web app from a prompt and still owning the code
Our pick · AI app builder with a visual editor
WebTwizz builds a full web app from a plain-language prompt: pages, logins, database and payments. You get the full code, in a normal format any developer can work with. You can change it three ways, by asking the AI, by selecting elements in a visual editor, or by editing the code, and all three change the same project.
WebTwizz compared with Replit
Replit can build almost anything. WebTwizz does one thing: full-stack web apps from a prompt, with code you own and a visual editor on top. The pricing model is the main contrast. WebTwizz plans are a flat monthly price, and hosting and custom domains are part of the plan, not metered from your credits. Replit wins on scope, with any programming language, native mobile apps and a built-in database. With WebTwizz the database comes from a Supabase project or a database you connect.
Strengths
- +A real visual editor: select any element to change text, styles and layout without writing a prompt
- +Your app’s code is yours, in a normal format any developer can work with, not a locked-in one
- +Two-way GitHub sync, so you can keep working in Cursor or any other editor
- +Hosting, custom domains and version history are part of the product
- +Free credits every day on every plan, including paid ones
Limitations
- –Web apps and websites only. It does not produce native iOS or Android apps
- –Every app is built the same way. If you need a specific programming language or setup, a developer tool is a better fit
- –The code editor, code export and custom domains need a paid plan
- –A younger product with a smaller community than Lovable, Bolt or Replit
- Pricing
- Starter is free: 10 credits every day (up to 50 a month), a 100-credit signup bonus, and 1 published site. Standard is $25/mo for 1,500 credits or $40/mo for 3,000. Pro is $50, $70 or $100/mo for 4,500, 6,000 or 9,000 credits. Annual billing gives two months free.
- Your code
- You get the full code of every project. Paid plans include the code editor and a full code export. Two-way GitHub sync lets you work on the code in another editor and pull the changes back in.
- Hosting
- One-click publish to a webtwizz.app subdomain on every plan. Custom domains with SSL and private sites, where you invite people by email, are on paid plans.
- Database, logins, payments
- Connect Supabase for the database, logins and file storage, or bring your own Postgres, MySQL or MongoDB. Stripe, Resend, OpenAI, Anthropic, PostHog, Sentry and Google Sheets connect from the integrations panel. A built-in CMS covers simple content without a database.
2. Lovable: best for chat-first building with a backend included
Chat-to-app builder
Lovable builds a full-stack web app from chat: frontend, database, logins and integrations, hosted for you. The code is standard, with nothing proprietary. New projects since May 2026 arrive as fully built pages, which helps search engines read them. Older projects build their pages in the visitor’s browser instead.
Lovable compared with Replit
Lovable covers the most common Replit use, a web app with a database and logins, in a simpler chat-first product. Its backend is built in and hosting has no stated visitor or bandwidth cap. It is web only and limited to one programming language, and its credits draw their own complaints about running out.
Strengths
- +Two-way code sync is on the free plan, across GitHub, GitLab and Bitbucket
- +Priced per workspace with unlimited members on every plan
- +New projects arrive as fully built pages, which helps search engines read them
- +A broad built-in backend: database, logins, storage, backend logic and payments
Limitations
- –Restyling a selected element goes through a prompt and costs credits. There is no manual style panel
- –Web apps only. Lovable does not build native phone apps
- –The free plan cannot edit code, download the code or use a custom domain
- –Running out of credits pauses building and the backend services of deployed apps
What users say
- Users report credits running out quickly, often on the AI retrying its own failed fixes on larger apps.
- Users report unused paid credits becoming unavailable after cancelling or downgrading.
- Pricing
- Free gives 5 build credits a day, capped at 30 a month. Pro starts at $25/mo for 100 credits ($21/mo billed annually) and scales up in credit tiers. Business starts at $50/mo. Plans are priced per workspace, not per seat, and credits roll over on paid plans.
- Your code
- Two-way sync with GitHub, GitLab or Bitbucket on every plan, including Free. Editing code in the product and downloading the code need a paid plan. You cannot bring in existing code. Lovable always creates a new code project.
- Hosting
- Publishes to a lovable.app address on every plan. Custom domains need Pro or higher. Heavy backend or hosting usage draws on a separate pool of Cloud credits.
- Database, logins, payments
- Lovable Cloud includes a database, logins, file storage, backend logic and scheduled jobs, built on Supabase. You can bring your own Supabase project instead. Payments run through Stripe or Paddle on Pro and up.
3. Bolt.new: best for more choice in how the app is built, and a route to mobile apps
AI builder that runs in your browser
Bolt is an AI builder for websites, web apps and mobile apps, made by StackBlitz. It runs a full coding workspace in your browser, generates code from chat, and bundles hosting, domains and a database as Bolt Cloud. Backends are limited to one programming language.
Bolt.new compared with Replit
Bolt is the closest to Replit in spirit, a real coding workspace in the browser with an agent. It is limited to one programming language, so backends in other languages are out. In exchange, manual code edits and visual edits cost nothing, and paid hosting has a fixed allowance. Both have a route to native mobile apps.
Strengths
- +Supports several coding setups instead of one fixed way of building
- +A documented path to native phone apps
- +Visual edits and manual code edits cost no tokens until you save
- +Zip download and two-way GitHub sync, including bringing in existing code from GitHub
Limitations
- –Backends are limited to one programming language
- –A web project cannot easily become a mobile one later. Mobile has to be chosen in the first prompt
- –Free hosting goes offline once the monthly cap is hit
- –Token use climbs as the project grows
What users say
- Users report tokens being spent on the AI fixing errors it introduced.
- Users report slow customer support, including on paid plans.
- Pricing
- Free includes 1M tokens a month with a 300K daily cap. Pro starts at $25/mo for 10M tokens ($18/mo billed annually) with higher token tiers above it. Teams is $30 per member per month. Token use grows with project size because Bolt re-reads project files on each message.
- Your code
- The code view lets you edit files directly, and manual edits cost no tokens. You can download the project as a zip, sync both ways with GitHub, and bring in existing code from GitHub.
- Hosting
- Publishes to a bolt.host address. The free plan has a hard cap of 10 GB bandwidth and about 333,000 requests a month, and the site goes offline when it is exceeded. Custom domains need a paid plan. Netlify is an alternative deploy target.
- Database, logins, payments
- Bolt Cloud creates a database with logins, file storage and backend logic when the app needs one. Supabase works as an alternative, and Stripe handles payments.
4. Base44: best for internal tools with everything handled in one place
All-in-one AI app platform
Base44 is a no-code AI platform for full-stack apps, owned by Wix since June 2025. It generates a standard frontend wired to Base44’s own managed backend: database, logins, backend logic and hosting, all set up automatically.
Base44 compared with Replit
Base44 shares Replit’s everything-included approach, with database, logins, hosting and payments, and no metered hosting bill. Plans are fixed monthly prices with credit allowances. The catch is portability. Replit gives you full version history and a standard database, while a Base44 app depends on Base44’s own backend.
Strengths
- +The most complete built-in backend here, with no third-party accounts to set up
- +A low paid entry price that includes a custom domain and code editing
- +Database operations do not use credits. Only built-in services do
- +A documented flow for packaging the web app for the app stores
Limitations
- –Apps depend on Base44’s hosted backend, so moving off the platform means rebuilding the backend
- –GitHub sync, backend logic and payments all need the $40/mo Builder plan
- –Mobile apps are a wrapper around the web app, not native code
- –Credits never roll over
What users say
- Users report credits draining in AI error loops, with no refunds for them.
- Users report concern about lock-in because the backend is proprietary.
- Pricing
- Free includes 25 message credits a month (5 a day) and up to 5 apps. Starter is $20/mo, or $16/mo billed annually, with 100 message credits. On annual billing, Builder is $40/mo and adds GitHub sync, backend logic and payments, Pro is $80/mo and Elite is $160/mo. Credits never roll over.
- Your code
- Editing code in the product needs a paid plan. Two-way GitHub sync needs the Builder plan or higher, and the data structure is not included in the code on GitHub. The frontend is standard code, but it only works with Base44’s hosted backend. Exporting the code still leaves the backend on Base44.
- Hosting
- Every app is live on a base44.app address from the start. Custom domains need the Starter plan or higher.
- Database, logins, payments
- Built in: its own managed database, logins with single sign-on providers, storage, backend logic, automations, email sending and analytics. Payments run on Base44 Payments, powered by Wix, from the Builder plan.
5. v0 by Vercel: best for teams already building on Vercel
AI app builder from Vercel
v0 is Vercel's AI app builder. It used to generate individual interface pieces only. Since a February 2026 update it builds full-stack apps, with a code editor, a developer-style review workflow on GitHub, and previews that run the real app. It deploys to Vercel.
v0 by Vercel compared with Replit
v0 suits a developer leaving Replit for a cleaner frontend workflow. It produces standard code on GitHub, with a review step and a preview of each change on Vercel. It has no database or logins of its own, so you put together what Replit bundles.
Strengths
- +A detailed visual editor on the free plan: typography, spacing, borders, shadows and more
- +A developer-style workflow on GitHub where each change can be reviewed and previewed before it goes live
- +Output is standard code in a common, widely used setup
- +Per-model token rates are published on the pricing page
Limitations
- –No built-in database or logins. You connect and manage those services yourself
- –It is built around one way of building apps. Other setups are possible but less reliable, per the docs
- –Hosting means a Vercel account, with Vercel’s own pricing on top
- –The free plan stops at 7 messages a day
What users say
- Users report monthly credits running out within days since the move to usage-based pricing.
- Users report the agent looping and spending credits on its own mistakes.
- Pricing
- Free includes $5 of monthly credits and 7 messages a day. Plus is $30 per user per month with $30 of credits and $2 of free credits each day you log in. Business is $100 per user per month. Credits are spent per token at each model’s rate, and chat history counts as input.
- Your code
- A built-in code editor with search and a view of what changed. GitHub sync is on the free plan: each chat works on its own copy of the code, and v0 saves each change to GitHub and proposes it for review. You can bring in existing code from GitHub.
- Hosting
- One-click deploy to Vercel with a vercel.app address, plus a separate live preview for each chat’s copy of the code. Custom domains are set up in the Vercel dashboard.
- Database, logins, payments
- No database or logins of its own. The backend is code inside the app itself, plus Vercel Marketplace integrations such as Supabase, Neon, Upstash and Stripe.
6. Cursor: best for developers working on code they already have
AI code editor
Cursor is an AI code editor and coding agent: a desktop editor, a command-line tool and cloud agents that work on your code and propose changes for review. It edits code in any programming language. It does not host your app or give you a database.
Cursor compared with Replit
If you used Replit as an AI-assisted editor more than as a host, Cursor is the desktop equivalent. It works on any code in any programming language. You take on hosting and the database yourself, which also means you choose what they cost.
Strengths
- +Works on any existing code in any programming language, with nothing locked to a platform
- +A wide choice of models at published per-token rates
- +Cloud agents run in parallel, test their work and propose changes for review
- +Design Mode lets you click an element in the running app to direct a change
Limitations
- –You need to be able to code. It assumes you can run a project, review changes and manage code versions yourself
- –No hosting, database or logins. You assemble and pay for those separately
- –Design Mode is a way to prompt the agent, not a style panel. Every change uses a model
- –Included usage can run out well before the month ends under heavy agent use
What users say
- Users report the $20 plan’s included usage running out within days of heavy agent use.
- Users report being blocked from even small tasks once both usage pools are spent.
- Pricing
- Hobby is free with limited agent requests. Pro is $20/mo, Pro Plus is $60/mo and Ultra is $200/mo, each with more included usage. Teams starts at $40 per seat. Usage is billed by tokens from monthly pools, and once they run out you pay on demand or wait for the next cycle.
- Your code
- The code is already yours. Cursor edits files on your machine, and cloud agents work on a separate copy of your code on GitHub, GitLab or Bitbucket. There is nothing to export.
- Hosting
- None. You deploy the app yourself, wherever you choose.
- Database, logins, payments
- None built in. Cursor writes code against whatever database and login service you set up.
7. OpenAI Codex: best for developers who already pay for ChatGPT
AI coding agent
Codex is OpenAI’s coding agent. It comes with ChatGPT plans and runs as a command-line tool, an editor extension, in the ChatGPT desktop app, on the web and on iOS. It reads and edits your code, runs commands, and in the cloud works on tasks in parallel and proposes changes for review.
OpenAI Codex compared with Replit
Codex comes with ChatGPT plans and works in your terminal, your editor or the cloud, proposing changes for review on your code. For a developer it replaces Replit’s Agent, but not its hosting or database. The Sites beta can host simple apps, without payments.
Strengths
- +No extra subscription. It is part of every ChatGPT plan
- +Runs where developers work: terminal, editor, desktop app, web, GitHub and Slack
- +Cloud tasks run in parallel and end in a set of changes you can review
- +The command-line tool and its developer kit are open source
Limitations
- –Built for developers. Everything happens in code files and code reviews
- –No visual editor. Every change is a prompt
- –Sites hosting is a beta with limits on what an app can do, and payments are not allowed on it
- –Usage limits are estimates per 5-hour window, not fixed numbers
What users say
- Users report usage limits draining much faster than expected during normal work.
- OpenAI confirmed an incident in June 2026 in which limits were wrongly depleted for some accounts.
- Pricing
- There is no separate Codex subscription. It is included in every ChatGPT plan, from Free and Go ($8/mo) to Plus ($20/mo) and Pro (from $100/mo). Usage comes out of your plan’s allowance, shown as estimated messages per 5-hour window, and weekly limits can also apply.
- Your code
- Codex works on your own files, on your computer or in the cloud, where it copies your code from GitHub and returns a set of changes for you to review. The command-line tool is open source.
- Hosting
- ChatGPT Sites, in public beta on Plus and higher plans, can host a website or web app with custom domains. OpenAI’s terms do not allow Sites to take payments. Outside Sites, you deploy the code yourself.
- Database, logins, payments
- Codex has none. Sites adds a database, file storage and "Sign in with ChatGPT". Anywhere else you bring your own backend.
8. GitHub Copilot: best for teams already working on GitHub
AI coding assistant
GitHub Copilot is an AI coding assistant inside your editor: code completions, chat, an agent mode, and a cloud agent that picks up a task on GitHub and proposes a change for review. Copilot Workspace was shut down in May 2025, and GitHub Spark, its prompt-to-app product, stopped accepting new users in August 2026.
GitHub Copilot compared with Replit
For people who came to Replit to learn or to code with help, Copilot is the low-cost option at $10/mo with unlimited completions, inside almost any editor. It assists with code and does not build or host an app for you.
Strengths
- +The cheapest paid plan here at $10/mo, with unlimited completions
- +The widest editor support: VS Code, Visual Studio, JetBrains, Xcode, Neovim and more
- +Built into GitHub. Assign a task to Copilot and get a proposed change back for review
- +Enterprise controls such as policy management and audit logs
Limitations
- –You need to be able to code. It assists with code and does not build or host an app for you
- –No hosting, database, logins or visual editor
- –The cloud agent is capped at 59 minutes per session and one proposed change per task
- –AI credits reset monthly and do not roll over
What users say
- Users report using up the monthly credit allowance in hours or days after the June 2026 switch to usage-based billing.
- Pricing
- Free includes 2,000 completions a month and limited chat. Pro is $10/mo, Pro+ is $39/mo and Max is $100/mo. Business is $19 and Enterprise $39 per user. Since June 2026 chat and agent work are billed in AI credits that do not roll over. Code completions stay unlimited on paid plans.
- Your code
- Your local files and your code on GitHub. The cloud agent only works with code hosted on GitHub.
- Hosting
- None.
- Database, logins, payments
- None built in.
