Vercel for AI Agents – One click deploy for the Claude Agent SDK
Founders
Hiring Pitch
Castari is building the deployment platform for AI agents, the way Vercel became the default for web apps.
The world is shifting from “prompting a model” to shipping autonomous software. Agents will run real workflows: pulling data, browsing, generating files, calling tools, and coordinating multi-step tasks. That’s a massive new surface area for reliability, security, and operations.
Right now, most agent teams are duct-taping together infrastructure that was never designed for this. The result is predictable: fragile deployments, unclear failure modes, unsafe execution, and almost no visibility into what happened when an agent goes off the rails.
Castari’s long-term goal is to be the go-to runtime and control plane for agentic applications. A place where teams can deploy agents with confidence, run them safely, observe everything, and scale without rebuilding their stack every time the agent gets more capable.
We’re starting with a deliberate wedge: Claude Agent SDK. Our goal is simple: when you build an agent with the Claude Agent SDK, Castari should be the obvious place to deploy it.
Tech Stack
We’re building the runtime + control plane for agentic applications, starting with Claude Agent SDK and expanding outward over time.
What we’re building toward
- A safe execution layer for agents that can take actions in the real world
- A deployment workflow that feels as simple and repeatable as modern web deploy
- A control plane for environments, versions, policies, and team operations
- Observability that actually matches the problem: agent runs should be inspectable, auditable, and debuggable
- A platform that scales from single-developer projects to mission-critical production workloads without teams rebuilding their infra
Why this is hard (and interesting)
Agents are fundamentally a new type of software. In order to usher in the age of agents, the core infrastructure needs to be rebuilt.
This is critical infrastructure we are building with taste. Developer experience, safety, and correctness all matter at once.
