- build - Default, full-access agent for development work
- plan - Read-only agent for analysis and code exploration
- Denies file edits by default
- Asks permission before running bash commands
- Ideal for exploring unfamiliar codebases or planning changes
Also included is a general subagent for complex searches and multistep tasks.
This is used internally and can be invoked using @general in messages.
Nellie Code ships with prebuilt stack profiles in packages/opencode/config:
nellie-stack.local.jsonc: local vLLM first, then Ollama/cloud and Anthropic/OpenAI backup.nellie-stack.cloud.jsonc: Ollama/cloud first, then Anthropic/OpenAI.nellie-stack.safe.jsonc: cloud-only safety fallback.
Set NELLIE_CODE_STACK=local|cloud|safe|auto (default auto) before launching.

If you are working on a project that's related to Nellie Code and is using "nellie-code" as part of its name, for example "nellie-code-dashboard" or "nellie-code-mobile", please add a note to your README to clarify that it is not built by the Nellie Code team and is not affiliated with us in any way.
It's very similar to Claude Code in terms of capability. Here are the key differences:
- 100% open source
- Not coupled to any provider. Nellie Code can be used with Claude, OpenAI, Google, or local models. As models evolve, the gaps between them will close and pricing will drop, so being provider-agnostic is important.
- Out-of-the-box LSP support
- A focus on TUI. Nellie Code is built by terminal-first developers; we are going to push the limits of what's possible in the terminal.
- A client/server architecture. This can allow Nellie Code to run on your computer while you drive it remotely from a mobile app, meaning that the TUI frontend is just one of the possible clients.
