6 AI tools to build websites and grow in 2026

AI website tools now split into three lanes: heavily funded platforms racing toward fully autonomous, self-updating sites, free and open-source tools that hand you the workstation instead of a subscription, and workflow tools built specifically for design agencies that still want to own the design work.

These 6 tools differ by funding path, target user, and how much control you keep over the finished site:

• Flint: a VC-backed platform building toward websites that update themselves, backed by a $5M seed from Accel and Sheryl Sandberg's fund.
• Lovable: the funding story of the category, its valuation went from $1.8B to $13.3B in eight months on $500M in annualized revenue.
• Base44: built solo with no outside funding, acquired by Wix for $80M in cash within six months of launch.
• Relume: bootstrapped and built specifically for design agencies still working in Figma and Webflow, not replacing them.
• Ship Studio: free, open-source, and local-first, a "workstation" that plugs into whatever AI coding agent and host you already pay for.
• Onlook: open-source and YC-backed, a visual editor for React and Next.js sites, often described as "Cursor for designers."

One honesty note upfront: Lil Big Things is a Webflow deign agency, so we have a point of view on where these tools genuinely help a build and where they don't. Read the breakdown below and judge for yourself where each one fits your stage and team.

We looked at funding source (VC-backed, bootstrapped, or acquired), what each tool actually outputs (a marketing site, a full app, or a design-to-code handoff), pricing, and who the tool is realistically built for, a solo founder, an enterprise team, or an agency.

Quick comparison: 6 AI tools to build websites and grow

The 6 AI tools to build websites and grow

1. Flint

Overview: Flint pitches itself as autonomous websites that build themselves. It was founded by former Warp growth lead Michelle Lim and ex-Nuro engineer Max Levenson, and it emerged from stealth in October 2025.

Funding & backing: $5 million in seed funding led by Accel, with Sheryl Sandberg's Sandberg Bernthal Venture Partners and existing backer Neo also participating, according to the official announcement.

Best for: growth and marketing teams that need new pages shipped in a day instead of coordinated across design and dev for weeks.

Capabilities:

• Analyzes an existing site's HTML, CSS, and design tokens to generate on-brand pages
• Assembles pages from familiar blocks: hero sections, feature grids, comparison tables, FAQs, forms
• Customers still write the copy; Flint handles design, layout, and tracking hooks
• Roadmap includes auto-generating comparison pages when a competitor launches, and pitching directly to AI agents that browse a site on a visitor's behalf

What makes it stand out: Flint is explicitly building for a world where ChatGPT and other AI agents browse websites on a person's behalf, not just for a human reading a page. That's a "build for growth" bet most website tools aren't making yet.

Pricing: not public. Flint is still in invite-only beta with a waitlist.

2. Lovable

Overview: Lovable is a Stockholm-based "vibe coding" platform, founded in late 2023 by Anton Osika and Fabian Hedin, that turns a plain-language prompt into a working website or app.

Funding & backing: Lovable's valuation moved from $1.8 billion in mid-2025 to $6.6 billion in December 2025, then to $13.3 billion by August 2026, when it closed a $400 million Series C led by Menlo Ventures and the EU's Scaleup Europe Fund. Total funding sits above $530 million.

Best for: solo founders and enterprise teams who want a working site or app fast, and are comfortable with a hosted, all-in-one platform.

Capabilities:

• Full-stack website and app generation from a prompt
• Used by both individual builders and enterprise customers including Workday, Asana, and Nvidia
• Hit $500 million in annualized run-rate revenue in June 2026, per Bloomberg's reporting on the round

What makes it stand out: the speed of the funding, not just the product. Lovable roughly doubled its valuation twice in under a year, which is the clearest signal that investors see AI website and app building as infrastructure, not a feature.

Pricing: freemium, with paid tiers that scale by usage and project complexity.

3. Base44

Overview: Base44 is a chat-based platform for building custom software and websites without code, founded by Israeli developer Maor Shlomo in early 2025.

Funding & backing: Base44 never raised outside funding. Wix acquired it for $80 million in cash roughly six months after it launched, with more payable through 2029 on revenue targets, according to Calcalist's coverage of the deal.

Best for: non-technical founders who want a single conversational interface to handle the backend, database, auth, and deployment.

Capabilities:

• Fully automated, chat-based build process, no manual setup for databases or hosting
• Existing B2B customers at the time of acquisition included eToro and SimilarWeb
• Continues to run as a distinct product and brand under Wix rather than being folded in

What makes it stand out: Base44 is the exit case study for this category, not a raise. A single founder, fewer than 10 employees, no VC money, and an $80 million cash sale in under a year is a different kind of proof point than Lovable's funding trajectory.

Pricing: now runs under Wix's pricing structure as a standalone product.

4. Relume

Overview: Relume generates sitemaps and wireframes from a prompt, then exports them directly into Figma or Webflow. It's built by a seven-person team with backgrounds at Canva and startup accelerator Antler.

Funding & backing: bootstrapped since founding in 2020. No VC funding disclosed.

Best for: design agencies and freelancers who want AI to speed up the front end of a project, sitemap and wireframe, while keeping the actual design and build inside their own process.

Capabilities:

• AI-generated sitemaps from a short project description
• Wireframes populated with real, human-built components from Relume's own library
• AI copywriting for wireframe content
• Direct export to Figma and Webflow

What makes it stand out: Relume's own numbers point to retention, not just signups, around 54,000 users and roughly 90% retention. It's the one tool on this list explicitly positioned to help a design agency finish more projects per month, rather than replace the agency's process outright.

Pricing: free tier available; Starter plan from roughly $26 per user per month, Pro from roughly $58.

5. Ship Studio

Overview: Ship Studio is a free desktop app, not a hosted website builder. It's a workstation that connects an AI coding agent, a Git host, and a deploy target in one window.

Funding & backing: funded by Native, a web and product studio that's part-owned by Ship Studio's own founders. No outside investment.

Best for: freelancers and agencies who don't want to be locked into one AI vendor or one hosting platform.

Capabilities:

• Works with Claude Code, Codex, or OpenCode, whichever AI agent you already pay for
• Live preview, visual editing, Git branches and pull requests, one-click deploy to Vercel, Netlify, or Cloudflare
• Code lives locally on your machine, not on Ship Studio's servers
• No Ship Studio subscription on top of the tools you already use

What makes it stand out: according to its GitHub repository, Ship Studio explicitly positions itself as agent-agnostic. It doesn't sell AI tokens or lock you into a single model, which matters for agencies that don't want their client delivery pipeline tied to one vendor's roadmap.

Pricing: free, with no paid tier. You only pay for the agent and hosting accounts you connect.

6. Onlook

Overview: Onlook is an open-source visual editor for React and Next.js sites, built by Daniel Farrell and Kiet Ho and often described as "Cursor for designers."

Funding & backing: $500K seed in March 2025, backed by Y Combinator (W25) and Leonis Capital.

Best for: teams that want designers and developers editing the same real codebase, instead of handing off static mockups.

Capabilities:

• Visual, Figma-like editor that writes directly to React/Next.js code
• Real-time DOM editing with AI syncing changes back to source
• Import from Figma and GitHub; supports real-time collaboration

What makes it stand out: Onlook hit #1 on Hacker News and became the top trending repository on GitHub at launch, ahead of DeepSeek, with over 8,500 stars. That's a genuine open-source adoption signal, not a funding number.

Pricing: free and open-source; self-host or use the hosted early-access version.

What's changing about AI website tools in 2026

1. Most AI-built output is still marketing sites, not full apps.

Business and portfolio websites account for 49% of projects built on Hostinger Horizons, against 10% for ecommerce stores and 5% for SaaS dashboards. Despite the "vibe coding" framing around full apps, the actual volume of AI-generated output still looks like a marketing site problem first.

2. Adoption has moved past the early-adopter phase.

41% of businesses now use AI-powered tools specifically for website creation, and that rises to 70% among businesses with mature AI strategies, according to Hostinger's 2026 data. 58% of small businesses now use generative AI at all, more than double the 23% figure from 2023.

3. Funding and exits are both happening, on different timelines.

Lovable's valuation moved from $1.8 billion to $13.3 billion in about a year on VC money. Base44 got acquired for $80 million after six bootstrapped months with none. Relume and Ship Studio never raised at all and are still growing. There's no single "right" funding path in this category yet, which is worth remembering before you pick a tool based on funding size alone.

Where a design agency fits into all of this

None of these tools remove the need for a design agency, they change what an agency spends its time on. A prompt-to-site tool like Flint or Lovable can produce a working page fast, but fast isn't the same as on-brand, conversion-tested, or built to a client's actual information architecture.

That's the gap Relume is built for: it hands a design agency a sitemap and wireframe in minutes, then lets the agency's own designers finish the job in Figma or Webflow, where brand judgment and client context still matter. Ship Studio takes the same approach on the development side, it's a workstation for an agency's existing AI agent and hosting stack, not a replacement for the agency's process.

That's also the model we use at Lil Big Things: AI speeds up the scaffolding (sitemaps, wireframes, first drafts), and a Webflow development team still owns the CMS architecture, the design system, and the parts of a site that actually move a trial-to-paid or lead-to-demo number.

Which AI website tool should you actually use?

• Need a page live today and don't mind a hosted platform: Flint or Lovable.
• Want to build software, not just a marketing site, from a prompt: Lovable or Base44.
• Run a design agency and want faster sitemaps without losing design control: Relume.
• Want to own your stack and not depend on one AI vendor: Ship Studio.
• Want a visual editor over a real, open-source codebase: Onlook.
• Want a partner who does the strategy and craft, not just the scaffolding: that's the Webflow agency conversation, not a tool conversation.

If you're weighing whether to hand a build to an AI tool or a design agency, our work and a free consult are the fastest way to figure out which one your stage actually needs.
