Reika
A coding agent CLI designed around small local models first
FreeCLIOpen SourceAI11 impressionslaunches Oct 13
- Context‑discipline preserves prompt cache for slow local models
- Loop‑breaking stops runaway reasoning
- Model work checks include type‑checking and read‑back
- Safe by default: dangerous commands prompt, sandbox on macOS
- Measured features with A/B switches and published findings
Reika is a CLI coding agent that works with local and hosted LLMs, optimized for small models.
- for
- Developers who want AI assistance in the terminal, especially with local models.
- pricing
- open source
- license
- Apache-2.0
Key features
- Context discipline — Keeps prompts short and append-only so local model caches stay efficient.
- Loop breaking — Detects and stops runaway reasoning, ending with an honest stop.
- Model work checks — Reads before blind edits, type-checks TypeScript changes, and tracks plan progress.
- Multiple modes — Plan, test-and-review, lean window, or chat modes selectable with Shift+Tab.
- Safety by default — Dangerous commands prompt; macOS shell commands run in a kernel sandbox; no telemetry.
- Measured features — Features are on by default but can be toggled for A/B testing, with published results.
Use cases
- Generate and apply code changes in a project using a small local LLM.
- Run a test-and-review workflow where the agent proposes edits and you approve them.
- Debug failing builds by letting the agent read errors, suggest fixes, and apply them safely.
- Interactively explore codebases via chat mode without leaving the terminal.

- Reika vs Cline: Cline is an open-source autonomous coding agent that runs inside an IDE, while Reika is a terminal CLI.
- Reika vs Aider: Aider provides AI pair-programming in the terminal, focusing on interactive assistance rather than the disciplined context handling of Reika.
- Reika vs Gemini CLI: Gemini CLI is Google’s open-source AI agent for the terminal, but Reika emphasizes safety and small-model efficiency.
- Reika vs OpenAI Codex: OpenAI Codex offers a coding agent for terminal, IDE, and cloud with OpenAI models; Reika targets local models first.
Reika FAQ
How do I install Reika?+
Use npm (`npm i -g @alexwkleung/reika`), pnpm (`pnpm add -g @alexwkleung/reika`) or Homebrew (`brew install alexwkleung/tap/reika`).
What models can Reika work with?+
It can point at any model server, including local models like Qwen3.6 35B via llama.cpp and hosted models.
Is Reika safe to run commands on my machine?+
Yes, dangerous commands require confirmation and on macOS they run inside a kernel sandbox; no telemetry is collected.
Can I switch between different operation modes?+
Yes, use Shift+Tab to toggle between plan, test-and-review, lean window, and chat modes.
Does Reika modify code without verification?+
No, it performs blind edits only after a read step, type-checks TypeScript edits, and tracks actual changes.
