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 Bolt.new
Bolt is a coding workspace with an agent. WebTwizz is a builder first, with the code there when you want it. You describe the app, then refine it in a visual editor that goes further than Bolt’s: select any element to change text, styles and layout, drag sections to reorder them, and work from a layers panel. Pricing is in credits, with 10 free every day on all plans. Bolt wins on flexibility. It offers more choice in how the app is built and a path to native phone apps, where WebTwizz builds web apps only, always the same way.
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. 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 Bolt.new
Lovable is the more guided version of the same idea. It gives you less access to the code than Bolt, since editing code and downloading it both need a paid plan, but the backend is more complete out of the box, with database, logins, storage and payments in Lovable Cloud. It uses credits where Bolt uses tokens, and draws the same complaints about usage running out. There is no mobile path.
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. 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 Bolt.new
v0 is the closest match for a developer who likes Bolt’s code-first feel. It produces standard code, brings in existing code from GitHub and runs every change through a developer-style review process. Its visual editor is more detailed than Bolt’s, with a full style panel. It has no built-in database, and unlike Bolt it leans heavily on one way of building and one host, Vercel.
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.
4. 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 Bolt.new
Replit removes Bolt’s one-language limit. It runs any programming language, and it includes a database, logins, storage and hosting in one account. Like Bolt it has a documented mobile path. Its billing is also usage-based and covers hosting and the database, so the cost worry does not go away. It just moves.
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.
5. 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 Bolt.new
Base44 is for the Bolt user who never wanted to see the code. Everything is set up for you, including the backend, and paid plans start at $20/mo. It is the least portable option here, because apps depend on Base44’s own hosted backend, where a Bolt project is standard code you can download.
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.
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 Bolt.new
If you use Bolt mainly as an AI pair programmer, Cursor does that job on your own machine on any existing code, in any programming language, with a choice of models. You lose the browser environment, the hosting and the database. You can pull a Bolt project from GitHub and carry on in Cursor.
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 Bolt.new
Codex is a coding agent included in ChatGPT plans. For a developer it replaces the agent part of Bolt at no extra cost, working in your terminal, your editor or the cloud. It has no visual editor, and its hosting feature, Sites, is a beta that does not allow 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. 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 Bolt.new
Devin Desktop, the editor formerly called Windsurf, is another local option for developers. It has unlimited tab completions on the free plan and can run several agents side by side. Like Cursor, it is an editor, not a builder: there is no production hosting, database or logins.
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.
