AI Tools for App Builders

Portkey is a platform for getting AI applications ready for production. It combines several capabilities aimed at keeping apps running reliably and securely:

ProjectX is an AI tool that acts as an AI co-founder for founders, automating the creation of full-stack applications. Instead of late-night coding sessions, hiring freelancers, or writing boilerplate, you describe your project, pick your preferred technologies, and confirm the requirements. AI agents then plan, build, and refine the application, often in minutes.

Pythagora AI is an open-source development tool that builds web apps by conversing with an AI. It assists with coding, includes a code editor, and uses large language models (LLMs) to streamline development. The tool generates automated integration tests by analyzing server activity, reaching approximately 80% code coverage after about 30 minutes of analysis, so test code doesn't need to be written manually.

RemixFast is an AI-powered no-code app builder that generates a complete, custom codebase rather than a throwaway prototype. A visual editor handles configuration, pre-built components support interactive dashboards, and you can go from data model to a running app with minimal manual coding.

Replit AI is an AI coding assistant built into the Replit platform. It provides smart coding tools and assistance directly within your coding environment, including code suggestions, auto-completion, and debugging help. It offers feedback and support in real time as you write and test code, and works across many programming languages.

Roya is an AI-powered tool for planning and designing APIs. It automatically generates sample endpoints tailored to your app's specific functions, which speeds up the initial planning stages. Roya supports web and mobile app development, offers real-time collaboration, and includes API documentation features. Its AI assists with tasks like creating request and response bodies, and you can annotate app screenshots to visualize how APIs interact with your application.

Shuttle is a service that takes developers from an idea to a fully working app in less than 5 minutes, without requiring them to manage infrastructure. It uses AI agents that interpret your request, write the code, set up the servers, and deploy everything automatically to Shuttle's Cloud.

SinglebaseCloud is an AI-powered low-code backend platform for building web and mobile apps. Its core features include:

Sketch2App generates UI code from hand-drawn sketches. Capture a sketch with a webcam or another camera, and the tool converts it into working code for mobile app development. It handles both single UI components and entire mobile applications, making it useful for building prototypes and designing apps quickly.

Softr is a no-code platform for building web applications without writing code. It covers use cases ranging from internal company intranets and client portals to custom tools for your team. Apps are assembled from ready-to-use building blocks such as Lists, Charts, Forms, Tables, Calendar views, and Maps.

Supabase is an open-source alternative to Firebase that provides a set of tools for building applications. It includes a Postgres database, authentication, instant APIs, edge functions, realtime subscriptions, and storage.

Sutro is an AI-powered platform for building full-stack applications without writing code. It uses Large Language Models (LLMs) to handle the entire app development process automatically, including backend setup. Non-technical users, such as founders with app ideas, can create custom, polished apps for iOS, Android, and the web. A built-in design system makes it easy to personalize your app and keep it updated after launch. To date, Sutro has helped 715 makers build 934 apps.
