Modern IDE for cloud and desktop development
Overview
Overview
Theia AI is an open framework for building customizable, AI-native tools and IDEs, designed to give developers complete control over AI integration. As part of the broader Theia Platform, it supports both cloud and desktop environments and is the foundation for the AI-powered Theia IDE—an open-source development environment offering transparency, flexibility, and full control over AI interactions.Theia AI enables developers to create domain-specific AI agents capable of complex, multi-turn conversations with native access to tool components. These agents can be embedded with advanced features like custom user interfaces, structured change sets, and interactive workflows. Developers can also define the agent’s context by integrating external APIs, databases, or scoped data, such as files or symbols dragged into a chat window.
The framework is model-agnostic, supporting cloud-hosted, local, and self-hosted language models, as well as external integrations like Anthropic’s Model Context Protocol (MCP). With advanced prompt management, custom UX components, and native context retrieval, Theia AI empowers teams to design sophisticated, workflow-aware AI experiences.
Ideal for teams building developer tools, technical editors, or complex automation systems, Theia AI provides the structure and adaptability needed to go beyond basic chat agents and embed intelligent behavior into modern, domain-tailored environments.

Johnson🙏 122 karmaJul 16, 2025@OnSpace.AI - No Code App BuilderWould rate 4.9 if possible, but rounding up to 5 stars because this app truly excels compared to other AI coding tools. Why 5 Stars: Best-in-class AI coding assistance Huge improvements over competitors Actually works for real development Real Impact: I successfully built and published an actual app using this tool - that's game-changing for non-developers like me. Bottom Line: Yes, there's room for improvement, but this is already the top AI coding app available. The fact that ordinary people can create real apps with it says everything. Perfect for anyone wanting to turn ideas into actual apps! -
Cursor — v2Much stronger coding performance, with big benchmark gains over Composer 1.5 across CursorBench, Terminal-Bench 2.0, and SWE-bench Multilingual. Better long-horizon task solving, aimed at coding jobs that require hundreds of actions instead of shorter edit loops. Stronger base model training from Cursor’s first continued pretraining run, giving reinforcement learning a better foundation than before. Better price-to-intelligence balance, positioned as a much stronger model without giving up cost efficiency. Adds a faster same-intelligence variant and makes fast mode the default option.

CodingFleet has evolved a lot over the past year. We added the latest flagship coding models including GPT-5.4, Grok-4.20 Beta, Gemini 3.1 Pro, Claude Sonnet 4.6 / Opus 4.6, Qwen 3.5, MiniMax M2.5, and newer Codex reasoning models. The platform also gained major new capabilities like Image Generation, Diagram Generator, Diagram-to-Code, vision support, improved Web Access, and MCP integrations. For builders, Code Execution became much more powerful with better sandboxes, filesystem tools, shell/database access, and improved long-running workflows. We also significantly improved the product experience with larger context limits, broader file upload support, Chat Memory, cross-tab/live chats, a much better dashboard, and detailed usage statistics. On the business side, we refreshed pricing with a stronger Pro plan, cheaper credit purchases, and permanent Pro access.

Code varies from run to run. Still it is a helpful app. You can specify coding languages that are not in the dropdown menu.
