How Stably ships AI testing agents in hours, not weeks

Stably, a 6-person startup building AI testing agents, shares how Vercel eliminated their infrastructure bottleneck and enabled shipping in hours instead of weeks.

• •Stably's AI agents run autonomous end-to-end tests by deploying on preview URLs, reading code diffs, and validating changes like a real user
• •Before Vercel, every new feature or agent required infrastructure decisions that consumed unsustainable DevOps overhead for a lean team
• •Their stack uses Vercel for frontend/backend, AI Gateway for scalability and large TPM limits, and Sandbox for agentic code execution
• •Removing deployment friction changed team culture: engineers now ship internal tools (Slack bots, dashboards, new agents) the same day ideas emerge
• •Winning Vercel's AI Accelerator brought investment, enterprise brand validation, and inbound leads that are now converting to contracts
