What does Runtime actually do?
Runtime addresses one of the biggest blockers in team adoption of coding agents: trust in execution. A coding model may already be good enough to propose changes, write code, or navigate a repo, but that does not automatically make it safe to run broadly inside a company workflow. The first serious questions are usually operational. Where does the agent run? What can it touch? How do several people use it without inheriting one engineer's local machine assumptions? Runtime is built around those questions, not around generic AI coding excitement.
That is why the sandbox angle matters. The value is not only that an agent can write code. The value is that the agent can run inside a controlled execution layer that the team can reason about. Once agents move beyond isolated demos, safety and repeatability become part of the product. The public pricing and docs make the platform easier to evaluate because they show this is being sold as a real team tool, with a free entry point and clearer operational framing than products that only present a vague agent promise.
