Bubble
Bubble is a cloud-based tool developed by Bubble with a focus on providing a comprehensive suite of features for developers. It supports multiple operating systems including Windows, macOS, and Linux, making it versatile for different user environments. Bubble is compatible with several large language models such as Claude Opus 4.5, OpenAI GPT-4o, GPT-5, and Hugging Face models. It offers a substantial context window of 200k tokens, although it does not support local inference.
