Overview
In the rapidly evolving landscape of AI-powered development, Gelt emerges as an innovative platform designed to transform how full-stack web applications are built. Launched on Product Hunt in October 2025, this browser-based tool enables users to transform ideas into production-ready, fully functional web applications in minutes—all without writing code or configuring complex development environments. What makes Gelt particularly remarkable is its origin story: built by Etai Gabbai, a 15-year-old developer frustrated with existing AI development tools that weren’t truly “agentic.” Gelt represents a new approach where an autonomous AI agent reasons, debugs its own code, and self-corrects in real-time to deliver working applications.
Key Features
Gelt distinguishes itself through innovative features that streamline the application development process from concept to deployment.
Pay-per-message pricing model: Gelt employs a cost-effective approach charging \$8.99 per month for its Pro plan with a pay-per-message structure. This differs from token-based pricing used by many competitors, potentially offering more predictable costs for certain usage patterns. The platform also offers promotional launch discounts for early adopters.
Autonomous AI agent for coding and debugging: At the heart of Gelt is a truly autonomous agent that doesn’t simply execute pre-planned scripts. The agent actively reasons about code architecture, identifies errors through self-reflection, and implements fixes without human intervention. This self-correction loop—teaching the agent to read error messages and debug its own code—represents the core technical challenge the creator solved. The agent continues iterating until it produces working, production-ready code.
One-click Vercel deployment: Once your application is complete, deploy it instantly to Vercel’s hosting platform with a single click, eliminating deployment complexity and ensuring your projects go live without delay.
Integrated Stripe, OpenAI, Anthropic, Google AI: Seamlessly incorporate essential third-party services into your applications. Stripe integration enables instant payment processing setup, while connections to leading AI providers including OpenAI, Anthropic (Claude), and Google AI allow you to build AI-powered features directly into your applications.
No prompt caching for consistency: Gelt intentionally avoids prompt caching, ensuring each interaction is processed fresh. This design choice prevents previous prompts from influencing new requests, maintaining output quality and consistency across complex, multi-step builds.
100% browser-based development environment: Develop, test, and deploy applications entirely within your web browser. This zero-setup approach eliminates the need for local development environment configuration, IDE installation, or complex toolchain management.
Multiple AI model options: Choose from leading AI models including Claude 4.5 Sonnet, GPT-5 Codex, Gemini 2.5 Pro, and GLM 4.6, providing flexibility to select the optimal model for your specific requirements and budget.
How It Works
Gelt simplifies the journey from idea to deployed application through an intuitive, conversational workflow. Here’s how you can bring your web application concepts to life:
Enter text prompt describing desired app: Begin by describing your web application in natural language. For example, “Create an e-commerce site with user authentication, product catalog, shopping cart, and Stripe checkout.” Gelt’s AI comprehends your intent and technical requirements from this description.
AI agent generates full-stack code automatically: Once you submit your prompt, Gelt’s autonomous agent analyzes your requirements and begins generating all necessary components: frontend UI, backend logic, database schema, API endpoints, and integration code. The agent works through the application systematically, building each layer of the stack.
Agent debugs and self-corrects: Unlike simpler code generators, Gelt’s agent actively tests its own work. When it encounters errors, it reads error messages, identifies root causes, and implements corrections. This self-healing loop continues until the application functions properly, significantly reducing the manual debugging typically required.
Test in browser environment: Before deployment, thoroughly test your newly generated application directly within Gelt’s browser-based development environment. You can interact with the application, verify functionality, and request modifications through continued conversation with the agent.
Deploy instantly to Vercel with one click: Satisfied with your application? Deploy it to Vercel’s global edge network with just one click, making your application live and accessible to users worldwide.
Pay per message interaction: Gelt’s pricing model charges based on message interactions with the agent rather than token consumption. This can provide more predictable costs for certain development patterns, particularly for smaller projects or focused build sessions.

Final Thoughts
Gelt represents an intriguing entry in the rapidly evolving AI-assisted development landscape, bringing a fresh perspective from a remarkably young creator who built the tool to solve problems he experienced personally. Launched in October 2025, it offers a compelling combination of autonomous agent capabilities, browser-based convenience, and competitive pricing that makes it worth considering for specific use cases.
The platform’s greatest strength lies in its truly autonomous agent that reasons about code, debugs itself, and self-corrects until producing working applications. This goes beyond simple code generation or completion, offering a more hands-off development experience than many alternatives. The \$8.99/month price point makes it accessible for solo developers, entrepreneurs, and agencies exploring AI-assisted development without significant financial commitment.
However, potential users should approach Gelt with realistic expectations about its current state. As a newly launched platform, it lacks the maturity, extensive documentation, and proven track record of more established alternatives. The agent’s thoroughness, while producing quality results, means builds may take longer than some faster but less sophisticated tools. The limited native integrations and evolving feature set mean some workflows may require workarounds or manual intervention.
Gelt appears best suited for rapid prototyping, MVP development, and scenarios where an autonomous agent’s self-correction capabilities outweigh the need for extensive platform features or immediate deployment integrations beyond Vercel. It’s particularly compelling for non-developers who can articulate their vision clearly and for developers who want to quickly validate concepts without setting up full development environments.
For production applications requiring extensive customization, strict performance optimization, complex regulatory compliance, or enterprise-scale features, more established development approaches or mature platforms may be more appropriate. Gelt excels at getting functional applications deployed quickly, but applications may require additional engineering for complex edge cases or production hardening.
The platform’s trajectory will depend on how quickly the team can mature the feature set, expand integrations, build community resources, and demonstrate reliability across diverse real-world use cases. The foundation—a genuinely autonomous, self-correcting agent—is compelling. The question is whether execution can match the ambition as the platform grows beyond its initial launch.
For developers and entrepreneurs seeking a low-cost entry point into AI-assisted application building with strong autonomous capabilities, Gelt deserves exploration. Its unique approach to agent autonomy and self-correction, combined with transparent pricing and zero-setup convenience, positions it as a noteworthy option in an increasingly crowded field. As with any early-stage tool, proceed with awareness of its current limitations while appreciating the innovative thinking behind its design.
