03 / The shortlist
Each alternative, in detail.
What each tool is, how it compares with Builder.io, what it costs, and where it falls short.
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 Builder.io
WebTwizz keeps Builder.io’s core idea, visual edits that change real code, and removes the prerequisites. There is no existing code to connect. You describe the app, WebTwizz builds it with code you own, and you edit it on a canvas or by prompt. Hosting, custom domains and integrations for Supabase and Stripe are included, and pricing is per account, not per user. If your team already has a large app and a design system, Builder.io is still the better fit, because WebTwizz does not import existing projects.
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. 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 Builder.io
v0 is the nearest alternative for an engineering team. It brings in existing code from GitHub, runs every change through a developer-style review process, and has a detailed visual style panel. Unlike Builder.io it deploys to Vercel in one click. 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.
3. Tempo: best for product teams shipping changes to an app they already have
Desktop tool for product teams
Tempo is no longer the browser-based app builder it launched as. It is now a downloadable desktop app that calls itself a coding workspace for the whole team. It turns feedback and reported issues into proposed code changes on your existing app, using your own Claude Code or Codex subscription, and has a canvas with a styling panel for visual edits.
Tempo compared with Builder.io
Tempo now does something very close to Builder.io’s Code product. It is a desktop app with a canvas where product teams change real components and send each change for review. Pricing is flat, not per credit, because you bring your own AI coding subscription.
Strengths
- +Designers and product managers can change the real interface on a canvas and send the change for review
- +Local-first. Your code stays on your machine
- +Flat pricing with no credits to run out
Limitations
- –It needs an existing app’s code. It does not build and host a new app from a prompt
- –You bring and pay for your own coding-agent subscription
- –No hosting, database or logins
- Pricing
- Free covers 250 issues and 100 docs. Pro is $50/mo for one user. Team is $200/mo with 5 users included, and extra users are $40/mo each. AI usage is not included. You connect your own coding-agent subscription.
- Your code
- It works on your own code and is local-first: the code stays on your machine, and changes are sent for review before they ship.
- Hosting
- None.
- Database, logins, payments
- None built in.
4. 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 Builder.io
Lovable is for people who came to Builder.io hoping to build an app and found they needed existing code first. It builds and hosts a full-stack app from chat, with a backend included. It has no manual style panel.
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.
5. 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 Builder.io
Bolt can bring in existing code from GitHub, as Builder.io can, and adds a coding workspace in your browser, hosting and a database. Its visual editor is basic next to Builder.io’s.
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.
6. Webflow: best for content-heavy marketing sites with fine design control
Visual website builder and CMS
Webflow is a hosted visual website builder and CMS for marketing sites. Its Designer maps closely to how web pages are coded, and its AI site builder generates a full website from a prompt. It is a website platform, not a prompt-to-app builder.
Webflow compared with Builder.io
If you use Builder.io’s Content product so that marketers can edit pages, Webflow is the established alternative, with a professional visual designer and a strong CMS, and hosting included. It is a website platform and does not work on your app’s code.
Strengths
- +A deep visual editor with reusable styles, variables and components
- +A strong CMS for content-heavy sites
- +Code export is available on paid workspace plans
Limitations
- –Built for websites, not apps with logins and a database
- –A real learning curve. It helps to understand how web pages are coded
- –Site plans, workspace plans and add-ons make pricing hard to follow
What users say
- Users report bill increases after the 2026 plan change, mainly from lower included bandwidth.
- Pricing
- Restructured in May 2026: the Basic site plan is $25/mo ($15 billed yearly) and Premium is $39/mo ($25 billed yearly) with 20,000 CMS items. AI credits are metered.
- Your code
- Code export is a feature of the Core workspace plan and above. Exported sites do not carry the CMS with them.
- Hosting
- Built-in hosting for sites. Custom domains from the Basic site plan.
- Database, logins, payments
- A CMS, forms and ecommerce plans. No general app database or logins for Designer-built sites.
7. Framer: best for high-polish marketing sites and landing pages
Visual website builder
Framer is a hosted website builder with a free-form, Figma-like canvas, a built-in CMS and AI agents that generate and edit pages. It builds websites. It does not build applications with a database or user logins.
Framer compared with Builder.io
Framer covers the same marketing-site need with a more free-form canvas and lower prices, from $10/mo. There is no code export, so it sits outside your engineering workflow entirely.
Strengths
- +The most design freedom here, with animations and effects
- +AI output lands on the canvas, where you can edit everything by hand
- +CMS, hosting and localization in one product
Limitations
- –Websites only. No database, logins or app logic
- –No code export and no self-hosting
- –Page and CMS item caps on each plan
- Pricing
- Basic is $10/mo and Pro is $30/mo, both billed yearly. Extra editor seats are $20/mo each, and AI agents are metered in credits.
- Your code
- Framer’s help center confirms there is no export of the site files for hosting elsewhere. Developers can add their own custom code components inside Framer.
- Hosting
- Built-in hosting only. Custom domains from the Basic plan.
- Database, logins, payments
- A CMS, forms and analytics. No application database, logins or payments.
8. 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 Builder.io
For the engineering half of the team, Cursor makes AI-driven changes to the same code and prepares them for review. It offers nothing for designers who want to edit visually.
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.
