Nano-Collective/nanocoder
Nanocoder is an open coding agent for the terminal, built by the Nano Collective, a community group that builds AI tooling without commercial tiers. It is model-agnostic by design: it runs local models through Ollama or any OpenAI-compatible API, including OpenRouter, Anthropic and Google endpoints, so the choice of which provider executes the work and where the data goes stays with the person running it. The README states there are no closed-source features, no paid tiers gating useful parts and no telemetry shipping prompts elsewhere. Installation is a global npm package, with Homebrew and Nix flakes also available. Command-line flags select provider, model and starting mode, and a run subcommand executes a single non-interactive request such as analysing or refactoring a file; flags may appear before or after that subcommand. Development modes include normal, auto-accept, yolo and plan, and can be chosen at boot. Two rendering modes are supported. Inline is the default and prints finished messages once into the native scrollback of the terminal, so the scrollbar, mouse wheel and search keep working and the transcript remains after exit. Fullscreen, enabled by an alt-screen flag or a preference, uses the alternate screen buffer with a fixed-height layout, in-app scrolling by mouse wheel or page keys, a scroll indicator and automatic snap-back to the bottom on new output; a no-alt-screen flag forces inline mode. In both modes a clear command resets the terminal to a fresh welcome banner and exiting erases the input UI cleanly. Documented features cover skills that bundle commands, subagents, tools and event triggers, a per-project daemon, checkpointing, task management, MCP server configuration, logging and timeouts, plus full slash-command and keyboard-shortcut references. Documentation is published online and in the repository, and the project takes contributions through a Discord community and scoped paid bounties described in its economics charter.
