InvokeAI

Open-source creative interface and workflow for local image generation, inpainting, and outpainting. Requires model files and suitable compute; usage rights depend on the selected model.

Presenton

Open-source AI presentation generator that turns prompts or documents into editable PowerPoint and PDF slides. Self-host it and connect a local or cloud model provider.

Cline

Free open-source coding agent extension for VS Code-family editors. It is an agent, not a full Windsurf-hosted IDE; model/API usage and any chosen tools may have separate costs.

SwarmUI

Modular local interface for running and comparing image and video models. Requires model setup and compatible GPU resources; model-specific licenses and limits apply.

Krita AI Diffusion

Krita plugin for local or remote diffusion-based image generation, inpainting, and outpainting inside a painting workflow. Requires Krita and a configured generation backend.

Chatterbox

Open-source text-to-speech and zero-shot voice-cloning model family from Resemble AI. Run locally with compatible hardware; the repository provides models and code, not a hosted voice studio.

NextChat

Open-source chat client for configurable AI providers. Requires your own compatible model endpoint or API key; provider charges and model access are separate.

Roo Code

Open-source coding-agent extension for VS Code with configurable modes and providers. It does not bundle model access or replace Windsurf's hosted IDE service one-for-one.
