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 Codex
If you came to Codex through Sites, hoping to turn an idea into a live app, WebTwizz is built for exactly that and goes further. It builds a full web app from a prompt, hosts it on your own domain, and connects Stripe, which Sites does not allow. You refine it in a visual editor, without prompting for every change. It is not a general coding agent. For work on existing code, Codex or Cursor is the right tool, and WebTwizz’s GitHub sync lets you use them on the same project.
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, a database, sign-ins, file storage, 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
- WebTwizz Cloud is built in, with nothing to set up: a database, sign-ins, file storage, scheduled jobs, error logs, analytics and Secrets for API keys. You can connect your own Supabase, Postgres, MySQL or MongoDB instead. Stripe, Resend, OpenAI, Anthropic, PostHog, Sentry and Google Sheets connect from Connectors. A built-in CMS covers simple content without a database.
2. 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 Codex
Cursor is the main alternative for developers. It is a full editor with agents built in, and it lets you choose between models from several providers, where Codex only runs OpenAI’s. It costs $20/mo on top of anything you pay for ChatGPT, and it draws its own complaints about usage pools running out.
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.
3. 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 Codex
Copilot’s cloud agent does the same job as Codex cloud tasks. You assign it a task and get back a change to review, all inside GitHub. At $10/mo it is the cheapest paid option, and it can delegate to third-party agents, including Codex. Sessions are capped at 59 minutes.
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.
4. Devin Desktop (formerly Windsurf): best for running several coding agents on one project
AI code editor
Windsurf no longer exists under that name. Cognition renamed the Windsurf editor to Devin Desktop in June 2026. It is the same desktop AI code editor, now built around a command center for local and cloud coding agents.
Devin Desktop (formerly Windsurf) compared with Codex
Devin Desktop, formerly Windsurf, is an editor that can run Codex and other agents side by side in one command center. It is less a replacement than a way to stop depending on a single agent.
Strengths
- +Unlimited autocomplete and inline edits, even on the free plan
- +One $20 subscription covers the desktop editor, the command line and cloud agents
- +Runs third-party agents such as Codex side by side
- +Add-ons, shortcuts and settings from VS Code carry over
Limitations
- –You need to be able to code. It is an editor for code on your own computer
- –No production hosting, database or logins
- –Quota sizes are not published, so it is hard to predict how far a plan goes
- –The product was rebranded and its agent replaced in 2026, so older guides no longer match
What users say
- Users report the March 2026 switch from credits to quotas as a sudden cut in how much they can use.
- Pricing
- Free has a light usage quota with unlimited autocomplete. Pro is $20/mo and Max is $200/mo. Teams has an $80/mo minimum. Usage is a daily and weekly quota measured in tokens, and the quota sizes are not published.
- Your code
- Local files on your machine, with your own version control. Cloud agents connect to GitHub, GitLab and Bitbucket.
- Hosting
- Preview-grade only. The built-in deploy feature is documented as intended for previews, and it does not work with the default agent.
- Database, logins, payments
- None built in.
5. Replit: best for building and hosting in one place, in any programming language
Online coding workspace with an AI agent
Replit is a browser-based coding platform. Its AI Agent builds apps from prompts, and the same product includes a code editor, a visual editor, a database, file storage, logins and hosting. It also builds mobile apps, with a documented App Store submission flow.
Replit compared with Codex
Replit is the fuller version of what Sites is aiming at. Prompt an app and host it in the same place, with a database, logins and storage built in, in any programming language, with connectors for Stripe. It is billed by usage across building and hosting.
Strengths
- +Editor, agent, database, logins, storage and hosting under one account
- +A click-to-edit visual editor where simple edits use no AI credits
- +Developer-style version control that syncs with GitHub both ways
- +Builds more than web apps, including mobile apps, in any programming language
Limitations
- –Usage-based billing. Building, hosting and the database all draw from the same credits
- –On the free plan, the published app link goes down after 30 days
- –Apps and databases go idle when unused, so the next visit starts slowly
- –It is a full coding workspace, which is more to learn than a focused builder
What users say
- Users report bills well above what they expected as credits drained.
- Users report the Agent fixing one thing and breaking another, with each repair costing more credits.
- Pricing
- Starter is free, with one published app whose link goes down after 30 days. Core is $20/mo ($18/mo billed annually) and Pro is $100/mo ($90/mo billed annually). Plans come as monthly credits, and Agent work, hosting, database and storage all draw from the same credits, with pay-as-you-go above that.
- Your code
- Code lives in a Replit workspace with full developer-style version control. You can bring in code from GitHub and send changes back to it.
- Hosting
- Built-in hosting on a replit.app address, with several deployment types. Custom domains are supported. Hosting is billed by usage from your credits, and autoscale apps go idle after 15 minutes of inactivity.
- Database, logins, payments
- Built in: a managed database, file storage and two login options (Replit Auth, or Clerk under your own brand). Connectors for Stripe and other services need the Core plan.
6. 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 Codex
Lovable is a chat-to-app builder with a complete backend and built-in payments through Stripe or Paddle, which covers the commercial case that Sites rules out. It is for people who want an app, not a coding agent.
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.
7. 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 Codex
Bolt sits between the two worlds. It is a coding workspace in your browser with an agent, a code view, hosting and a database. It suits a developer who wants Codex-style help with a running preview and one-click publishing.
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.
8. 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 Codex
v0 works the way Codex cloud does, proposing changes for review on your code in GitHub, but adds a live preview, a visual style panel and one-click deploys to Vercel. It is centred on one way of building.
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.
