Use the desktop app for free and connect the model providers you already pay for or host yourself.
NexaAct
Free desktop command center for AI agents.
If you are comparing Antigravity, Codex, or Claude Code, NexaAct's angle is ownership: a free desktop app, bring-your-own API, signed-in provider accounts, model switching inside the same conversation, and remote control through infrastructure you operate.
Bring OpenAI-compatible endpoints, custom API hosts, and provider-specific model menus into one workspace.
Keep ChatGPT, Antigravity, Claude, and API-backed models available together, then switch models in one conversation without changing accounts or keys.
Remote control runs through infrastructure you deploy and control, without NexaAct collecting remote data.
AI should operate every part of digital work, with the user in control.
NexaAct is built toward a simple goal: turn AI from a chat box into an operator for the tools, files, browsers, APIs, services, and remote computers people already use.
Free to use. Flexible by design. Controlled by you.
The core product story is simple: one local desktop workspace, your preferred model providers, your signed-in accounts and APIs, and your own remote-control infrastructure.
Agent workflows plus provider freedom
Inspect workflows, custom APIs, signed-in model accounts, same-conversation model switching, skills, plugins, and MCP support.
Phone control through your Cloudflare
No mobile app and no NexaAct-hosted relay. You deploy and operate the remote access layer.

macOS Apple Silicon remains the primary verified build, with additional platform packages tracked separately.
