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, custom providers, multiple OpenAI accounts, and remote control through infrastructure you operate.
Bring OpenAI-compatible endpoints, custom API hosts, and provider-specific model menus into one workspace.
Keep separate OpenAI accounts available for different projects, teams, or billing boundaries.
Remote control runs through infrastructure you deploy and control, without NexaAct collecting remote data.
Vision
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.
Local desktop control Bring-your-own models User-owned remote access
Why NexaAct
Free to use. Flexible by design. Controlled by you.
The core product story is simple: one local desktop workspace, your preferred model providers, your OpenAI accounts, and your own remote-control infrastructure.
