Product preview

Overview

MonkeyCode is an open-source, enterprise-oriented AI coding assistant from Chaitin Tech, deployable entirely on your own infrastructure. It pairs IDE-side completions with a self-hosted control plane for team management, audit and model routing — including support for domestic Chinese models and private deployments where cloud tools are off the table.

Its free plan is unusually generous for commercial use, which has made it a favorite among Chinese enterprises that want Copilot-style assistance without sending code to foreign clouds.
