Our decision to build an agentic ecosystem across the CLI, desktop, and cloud came from a deeper belief about how engineers actually work.

We understand that developers are opinionated about their tools, and we believe good products should respect that.

Most tools in the AI market pick one surface and expect users to adapt, assuming the product should define the workflow. If you want the benefits, you work the way the tool wants you to work. That can make the product easier to package, easier to explain, and easier to sell. But it often comes at the expense of the engineer.

Our team shares why an ecosystem matters, why the CLI is such an important foundation, and why meeting developers in their own environments is a better philosophy than trying to standardize how everyone works.

Work where you live

At Cosine, we think developers should be able to work where they already live. If that’s the CLI, the tool should feel native there. If desktop or the cloud makes sense for a different part of the workflow, that should exist as well. The point is not to force one ideal interface onto everyone, but to give engineers control over how they use the product.

That is a philosophical commitment as much as a product decision.

”Developers are opinionated in many ways, and one of the most opinionated stances they take is where they work and how they work.” – Alistair Pullen, CEO + Co-Founder

Engineers do not all work the same way, and they shouldn’t have to. Some want directness and composability. Some want a broader visual interface for monitoring, reviewing, or coordinating work. These are expressions of developer preference, habit, and taste.

Cosine is built to work with that reality rather than against it.

The platform offers several ways to work based on developer preference:

• CLI – Designed specifically for developers who prefer working in a terminal environment
• Desktop Application – A streamlined experience for those who prefer working within a standalone application
• Cloud – Offloads agent and system capabilities, allowing devs to run tasks asynchronously

Cosine’s agentic ecosystem is built on a commitment to respect the unique preferences and existing workflows of every engineer. By bringing a shared agent runtime to the CLI, desktop, and cloud, we ensure you don’t have to adapt your workflow to gain the benefits of AI.

We believe this is the more respectful, and ultimately, the more useful approach.
