The platform of Bolt.new promises code-free development right in your browser. The reality looks quite different. Users have burned through more than 2 million tokens just to fix bugs. One developer even had to spend an extra $1,000 on professional help to fix problems with the generated code.
I've tested this AI-powered development platform to give you the full picture of how Bolt.new works. You'll learn what it actually delivers and if it fits your next project. Let's take a closer look at this detailed review that reveals the good, the bad, and some surprising discoveries every developer needs to know.
What Is Bolt AI and How Does It Work?
StackBlitz's Bolt.new brings a radical alteration to web development methods. This AI-powered web development agent combines a browser-based IDE with artificial intelligence that generates code from natural language prompts.
Browser-Based IDE: No Local Setup Required
Bolt's core runs on StackBlitz's WebContainers technology that removes the need for local development environments. The in-browser system helps developers build full-stack applications without installing packages, setting up servers, or configuring databases locally. The user-friendly interface comes with a complete development environment that includes:
- Code editor with live preview
- Terminal for running commands
- File system navigation
- Integrated deployment options
The continuous connection lets you focus on building instead of configuration. This makes it especially valuable to validate ideas and create quick prototypes.
AI-Powered Code Generation Explained
Bolt's code generation engine uses Anthropic's Claude 3.5 Sonnet LLM to turn natural language prompts into working code. The process works like other large language models (LLMs) but focuses on programming tasks. Bolt follows these steps with your prompt:
- Analyzes your request to understand requirements
- Generates appropriate code based on patterns from its training data
- Creates necessary file structures and components
- Updates in real-time as you refine your prompts
The system excels at framework generation, UI components creation, and simple functionality implementation through prompt refinement. All the same, complex projects need more specific prompts to achieve desired results.
Token System: What You Need to Know
Bolt uses a token-based economy that affects both functionality and cost. Tokens are small pieces of text that the AI processes to generate responses. Understanding this system is vital because:
Larger applications need more tokens for each interaction. Paid plans begin at $20/month for 10 million tokens and go up to $200/month for 120 million tokens. Monthly tokens from paid subscriptions expire, but separately purchased token reloads carry forward.
Token consumption patterns have led developers to adopt a mixed approach. Many use Bolt to create the original framework or add major features before switching to traditional IDEs for detailed work. This strategy helps control token usage while employing Bolt's quick application generation capabilities.
Core Features Breakdown: What Bolt Promises vs Delivers
My detailed analysis of Bolt AI's capabilities reveals some stark differences between marketing claims and real performance. Let me share what developers actually experience with this browser-based development tool.
Project Framework and Deployment
Bolt says it can generate applications quickly with automated framework creation and one-click deployment. My tests show the platform does create good original project structures and organizes files properly. It handles npm package installation and server configuration without manual work.
But deployment isn't always smooth sailing. Bolt connects directly with Netlify to publish applications, but users run into problems as projects get bigger. The one-click deployment works great for simple applications. Larger projects need extra troubleshooting that goes beyond what the AI can help with.
Component Reusability and Modularity
Bolt markets itself as a creator of highly reusable, modular code. The AI generates components that keep concerns separate. It also creates well-laid-out projects with proper folders and files.
These strengths aside, the AI creates duplicate components or loses pattern consistency as projects grow larger. Then developers need to clean up the generated code manually to make it truly modular for production.
Error Handling and Debugging Capabilities
Bolt looks great on paper with its error detection and automatic fixes. Real-world experience shows the platform's debugging has major limitations. User reports show one developer used over 20 million tokens trying to fix a single authentication issue.
Bolt's "Discussion Mode" lets you debug without generating code, but this feature doesn't deal very well with complex errors. The platform spots simple syntax issues but misreads deeper architectural problems. This leads to burning through tokens in trial-and-error attempts.
UI Customization and Asset Management
Bolt claims to offer detailed customization and asset management for UI development. The system implements react-toastify for progress updates and handles asset uploads. It also works with MobileNet for asset tagging and classification.
Users report that the AI has trouble with complex UI customizations, especially with specific design systems or custom animations. Simple styling works fine, but getting pixel-perfect designs needs more manual work than the AI can handle.
Bolt Pricing and Token Model: Is It Worth the Cost?
Bolt's entire pricing model depends on token consumption, and this has started quite a debate in the developer community. Looking at their options, I noticed they offer various plans for different usage needs.
Pricing Tiers and Token Limits
The subscription model starts with a Pro plan that costs $20/month and gives you 10 million tokens. You'll find higher tiers like Pro 50 ($50/month for 26 million tokens), Pro 100 ($100/month for 55 million tokens), and Pro 200 ($200/month for 120 million tokens). Your paid subscription tokens don't roll over each month. You can buy extra token reloads separately if you need more capacity, and these will carry forward as long as your subscription stays active.
Token Consumption: Real User Complaints
Token consumption has turned out to be much more aggressive than expected. A user's Pro plan lost 1.3 million tokens in a single day. The situation gets worse - developers have burned through 7-12 million tokens just trying to fix simple errors. Your token usage grows by a lot as projects expand, and most users find this out too late.
The "diffs" feature helps save tokens but stays turned off by default. This feature stops Bolt from rewriting entire files during small changes and can save millions of tokens. Simple UI changes can eat up your monthly tokens faster without this setting.
Refunds, Subscription Traps, and Transparency Issues
Bolt gives you 30 days to ask for a refund, but users are not happy with what they notice as misleading consumption patterns. Your subscription will auto-renew unless you cancel it, and this has left many developers with unexpected charges after disappointing results.
Users have raised red flags about Bolt's token system's transparency. Some think it's "optimized for appearance of activity rather than genuine problem-solving". These worries grow stronger when you hear about people losing hundreds of thousands of tokens just on error messages.
Bolt.new vs Trickle and Other Alternatives
AI development platforms show clear differences in their methods and results. Looking at Bolt next to Trickle and other options reveals patterns in how they handle features, user experience, and real-life uses.
Feature Comparison: Bolt vs Trickle
Trickle AI works as a complete solution without extra add-ons, while Bolt needs external services like Netlify to deploy projects. The pricing models differ too. Trickle keeps it simple with a $20 monthly fee. Bolt uses tokens that can cost more as projects get complex. Trickle AI turns plain language into working web applications effectively. Bolt puts its energy into front-end work but doesn't give much backend help.
Developer Experience: Where Bolt Falls Short
Bolt creates problems for developers once their projects grow beyond basic prototypes. Some users spent over $1,000 on tokens just to fix code problems. This issue doesn't come up with platforms that charge fixed prices. Bolt's blank screens, missing files, and partial deployments make development harder than it should be. Trickle users like how they can work through prompts, which fits better with product managers who aren't technical.
Use Case Suitability: Prototyping vs Production
Bolt shines at quick prototypes and testing ideas. Developers can build features in minutes instead of hours. The platform hits its limits with bigger projects that need databases, server logic, or live updates. Trickle works better for teams where developers and designers need to work together quickly. Bolt helps you start fast and provides good support but doesn't handle production apps or complex tasks well.
Each platform fits different development needs. Bolt works best for quick prototypes. Trickle handles complete web applications smoothly. Other options specialize in UI development or full-stack capabilities.
Conclusion
My extensive testing shows that Bolt AI doesn't live up to its big promises. The platform works well to create quick prototypes and simple support structures. However, significant limitations surface when you need to build production-ready applications. Developers often spend thousands of dollars to debug generated code because of the token-based pricing model.
Bolt fails to provide the smooth development experience it advertises. Instead, it creates new headaches through unpredictable code generation and deployment problems while token allowances disappear faster than expected. You can use the platform to build simple demos and proof-of-concepts. Yet it doesn't deal very well with complex applications that need database interactions or real-time features.
Trickle AI emerges as a better choice with its predictable pricing and strong end-to-end development features. You won't have to worry about token consumption. Teams looking for dependable AI-assisted development tools will appreciate its fixed monthly subscription model, better code generation, and deployment options.
My advice? Don't waste time counting tokens or spending money on expensive debugging. Trickle delivers everything Bolt promises - and actually works.
