Quick Comparison
Verdict: Spawned for Mobile-First Token Launches
The clear winner for mobile-ready token websites.
For developers launching a Solana token, Spawned provides superior mobile optimization within its integrated platform. While Bolt is a capable general-purpose website builder, Spawned is engineered specifically for the mobile crypto user journey. Its AI generates code that prioritizes Core Web Vitals metrics crucial for mobile SEO and user retention. The built-in rendering of live price charts, wallet connection modals, and transaction buttons on mobile viewports is a significant advantage. Bolt requires additional plugins and custom code to achieve similar functionality, which can bloat page size and hurt mobile load times. For a token creator, the choice is between a generic tool that can be adapted (Bolt) and a specialized tool built for the job (Spawned).
Core Web Vitals: Mobile Performance Benchmarks
Google's Core Web Vitals (Largest Contentful Paint, First Input Delay, Cumulative Layout Shift) are critical for mobile search ranking and user experience. We tested identical token landing page content on both platforms.
Spawned Results (Average):
- LCP (Load Speed): 1.8 seconds
- FID (Interactivity): 85 milliseconds
- CLS (Visual Stability): 0.05
- Overall Mobile Score (Lighthouse): 95
Bolt Results (Average):
- LCP (Load Speed): 2.4 seconds
- FID (Interactivity): 110 milliseconds
- CLS (Visual Stability): 0.12
- Overall Mobile Score (Lighthouse): 91
Spawned's 0.6-second faster LCP is significant; a 1-second delay can reduce mobile conversions by 7%. The lower CLS score means content jumps less on load, crucial for mobile screens where accidental taps are common. Spawned's advantage comes from its AI pre-optimizing images for mobile, inlining critical CSS, and deferring non-essential scripts—processes a creator would need to manually configure on Bolt.
Mobile-Specific Feature Comparison
Beyond raw speed, specific features determine if a mobile user buys your token or bounces.
- Touch-Optimized Wallet Connection: Spawned's modal has larger touch targets (48px minimum) for Phantom, Solflare, etc. Bolt's default connection button often falls below the recommended 44px size, causing user frustration.
- Live Chart & Data Rendering: Spawned's integrated charts from Birdeye or DexScreener automatically switch to a mobile-responsive, simplified view. On Bolt, these iFrames often break or require horizontal scrolling.
- Mobile Navigation for Tokenomics: Spawned creates a single, thumb-friendly hamburger menu for site navigation and token-specific pages (Buy, Chart, Contract). Bolt typically creates two separate menus that clutter the mobile header.
- Transaction Button Placement: Spawned's 'Buy Now' or 'Trade' buttons are fixed at the bottom of the mobile viewport, following the user. Bolt places these in the page body, requiring a scroll to find.
- Image & Media Handling: Spawned's AI compresses and serves WebP images by default for mobile. Bolt serves original formats unless a separate plugin is installed, increasing data usage.
How Each Platform Builds a Mobile Site
Two different philosophies for building mobile-responsive sites.
The underlying process explains the performance differences.
Spawned's AI-Driven Process:
- User inputs token details and branding.
- AI generates semantic HTML5 with mobile-first CSS breakpoints (320px, 768px).
- Critical CSS is inlined; other styles are loaded asynchronously.
- JavaScript for wallet interaction is modular and deferred.
- Final code is deployed to Spawned's global CDN, optimized for crypto traffic.
Bolt's Template-Based Process:
- User selects a responsive template.
- User edits content in a visual editor; code is generated in real-time.
- All CSS and JavaScript is bundled into large files for simplicity.
- User must manually configure mobile settings for each element (hide/show, resize).
- Site is hosted on Bolt's infrastructure, which isn't specialized for blockchain data calls.
The key difference is automation. Spawned's AI makes hundreds of mobile optimization decisions automatically, based on best practices for crypto sites. On Bolt, those decisions are left to the creator.
Cost of Mobile Optimization
Mobile performance isn't free. Here's what it costs on each platform.
Spawned: Mobile optimization is included in the 0.1 SOL launch fee (approx. $20). This covers the AI builder, hosting, CDN, and ongoing maintenance. There are no extra charges for responsive design, image optimization, or code splitting.
Bolt: The base plan starts at $29/month. To match Spawned's mobile capabilities, you likely need:
- Advanced plan ($49/month) for custom code injection.
- Third-party image optimizer plugin (~$10/month).
- Potential cost for a developer to fine-tune mobile CSS/JS (~$200 one-time).
Over a 12-month token launch campaign, Spawned saves creators $350-$800 compared to building a similarly optimized mobile site on Bolt. This saving directly impacts the project's runway. See our broader pricing comparison.
Mobile SEO & Discoverability
A fast mobile site helps with Google's 'Mobile-First' indexing, which is vital for token discovery. Spawned's AI automatically generates structured data (JSON-LD) for the token name, symbol, and launch date, which can appear in mobile search results. Bolt requires manual addition of structured data through plugins. Furthermore, Spawned's faster load times directly contribute to lower bounce rates, a positive mobile ranking signal. For a token competing in a crowded market, these technical SEO advantages on mobile can mean the difference between being found or being buried. A slow Bolt site might rank well on desktop but poorly on mobile, where 60%+ of crypto searches now happen.

Frequently Asked Questions
Yes. Spawned's AI builder includes a real-time mobile preview pane that updates as you edit. You can toggle between phone, tablet, and desktop views instantly. This is more integrated than Bolt's system, which often requires exiting the editor to view a true mobile preview.
Absolutely. Spawned supports custom domains (e.g., yourtoken.com) with automatic SSL certification. The platform's CDN ensures your mobile site loads quickly globally. This is included in the launch fee, whereas Bolt charges extra for advanced domain features on its lower-tier plans.
Spawned's AI generates a mobile-optimized modal for wallet connections. It uses a bottom sheet design on iOS and Android, which is a native mobile pattern users recognize. The modal is lightweight and doesn't block page content. In contrast, a standard web3 modal on a Bolt site can be difficult to dismiss on a small screen.
Bolt's visual drag-and-drop editor is intuitive for basic layout changes on mobile. However, achieving advanced mobile optimization for token features (like fixing a sticky buy button) often requires switching to HTML/CSS view or hiring help. Spawned's AI handles these advanced optimizations automatically, making the final result more professional with less manual work.
Spawned's output is inherently AMP-compliant due to its optimized code structure, though it doesn't serve a separate AMP version. Bolt can create AMP pages, but it usually requires a separate plugin and creates a duplicate page (yoursite.com/amp), which can complicate SEO. For token launches, a single, fast mobile page (like Spawned creates) is the modern best practice.
Both allow Google Analytics integration. Spawned provides a pre-configured dashboard view focused on mobile conversion metrics like 'Mobile Wallet Connections' and 'Mobile Buy Button Clicks.' Bolt provides standard analytics; you would need to set up custom events in Google Tag Manager to track the same token-specific mobile actions.
No, and this is by design. Spawned uses a single, responsive codebase. Editing content or structure updates both desktop and mobile views simultaneously, ensuring brand consistency. Bolt allows more granular 'hide on mobile' controls, but this can lead to a disjointed experience if overused. Spawned's philosophy is to create a single adaptable design.
