Stably Cuts AI Test Agent Launch Time from Weeks to Hours

Key point

The 6-person startup Stably eliminated infrastructure burdens through Vercel, dramatically shortening the launch time for its AI test agent.

Details

The 6-person startup Stably is developing an AI end-to-end (E2E) test agent that deploys to preview URLs and reads and executes code to verify AI-written code. Even if AI writes code quickly, a manual verification process creates a bottleneck.

However, for Stably, the burden of infrastructure management (DevOps) was a bigger problem than the technical challenges. Having to make infrastructure decisions every time a new feature was added or an agent was deployed was an unsustainable overhead for a small team.

Stably solved this problem by adopting Vercel. It secures AI scalability through AI Gateway and uses Sandbox to support the agent's code execution. This allowed the team to focus solely on product development without worrying about infrastructure.

Once infrastructure was no longer an obstacle, the team's way of working also changed. Instead of worrying about deployment, developers began implementing ideas immediately, and internal tools like Slack bots and dashboards could now be built in just a few hours.
