Introducing Capsule CLI

I'm excited to launch Capsule CLI, a CLI tool that brings the power of the leading AI models in one unified interface.

There have been many ai clients and cli tools, but each implmentation has its own quirks and limitations.

With AI progress being so fast, the state of the art (SOTA) models are constantly changing every four to six months.

With Capsule CLI, my goal is to provide a interface that allows developers to use the best models as soon as they are available.

Why I Built Capsule

As a developer, I found myself constantly switching between different AI tools:

• Claude Code is the new state of the art agentic coding assistant, and it's a game changer, but it locks you into using Anthropic's models. Plus, it's demand has been so high that weekly limits are coming plus increasingly expensive subscription tiers not too far away.

• Google's Gemini CLI is a great free alternative to Claude Code, but it's not as powerful at agentic coding and still requires you to use Google's models, locking you into Google's ecosystem.

This is why I built Capsule CLI.

With Capsule CLI, developers can use the best models as soon as they are available, without being locked into a single provider's models.

What Makes Capsule Different

1. Unified Interface

Access OpenAI, Anthropic, Google, xAI, Meta, and many more providers models through a single CLI. Same commands, same workflow, different models.

2. Subagents

Claude is very powerful at writing code, planning, and agentic tool use. Whereas xAI's Grok is very powerful at science and math. Gemini series are cost effective and powerful at general purpose tasks.

Each model has its own strengths and weaknesses, and Capsule CLI allows you to use the best model for the task at hand. You can configure Capsule to use the best model for the task, and for micro-tasks, Capsule will spin up a subagent to handle the task using the best model for the task.

3. Model Orchestration

Building on top of Subagents, Capsule allows developers to execute tasks faster with parallel execution by spinning up multiple subagents automatically.

3. Built on OpenRouter

We leverage OpenRouter's robust infrastructure, giving you access to a vast ecosystem of models with built-in fallbacks and high availability.

4. Privacy First

Your conversations go directly through OpenRouter to the model providers. We don't store or analyze your data.

Getting Started is Simple

# Install Capsule
npm install -g capsule-cli

# Activate your license
capsule activate or /activate through the cli

# Start coding

What's Next

This is v0 of Capsule CLI, and I'm focused on making Capsule one of the best model agnostic AI tools out there.
