Hoplite (YC S26) Launches Cloud Deployment for Coding Agents with QA Previews

Hoplite (hoplite.sh) is a new service from YC S26 that deploys coding agents in the cloud with a focus on easily QA-ing features. It ports your local setup—sessions, memories, MCP servers—and gets your projects ready to run in the cloud. The founders, Bence and Ryan, built a custom agent harness instead of using off-the-shelf solutions like Codex or Claude Code, to have independence and test new features without waiting for Anthropic or OpenAI.

Key Features

• Custom agent harness: Built in-house, giving full control and flexibility to experiment with new agent behavior.
• Cloud infrastructure: Hosted on AWS, with Temporal for durable workflows, Modal for sandboxes, and Planetscale for the database. They emphasize reliability and security as agents become tier-0 infrastructure.
• Onboarding: Transfers your local sessions, memories, and MCP servers to the cloud, making setup seamless.
• Previews for QA: The team is optimizing previews to let developers visually verify new user flows, UI, API responses, and CLI behavior across platforms like Windows, while running hundreds of agents concurrently.

Pricing and Trial

You can try Hoplite for free with the code HACKERNEWS, which includes $100 in free credits. You can also connect your Codex subscription to use OpenAI models through Hoplite. More details at hoplite.sh/pricing.

Who It's For

Developers who want to run AI coding agents at scale in the cloud and need an efficient way to QA the results, especially those who expect to review product output rather than code as models improve.
