Render just removed its AI sandbox time limit — and Vercel still has a 24-hour cap
Render is taking on Vercel with AI sandboxes that can run indefinitely, along with new tools for managing long-running agent The post Render just removed its AI sandbox time limit — and Vercel still has a 24-hour cap appeared first on The New Stack .
Render has introduced AI sandboxes with no time limit and new tools for managing long-running agent workflows and shared storage. This removes Render's previous 30-day continuous runtime limit on paid workspace plans. In contrast, Vercel caps individual sandbox sessions at 24 hours. Render's sandboxes can suspend when idle and resume with their files, memory, and running processes intact, allowing agents to pick up mid-task.
Render founder and CEO Anurag Goel aims to make AI agents as accessible as AWS without the same infrastructure complexity. While credential brokering is available initially to selected customers, Render considers it a standard feature rather than a competitive advantage. The company emphasizes compute flexibility and less complexity compared to Vercel, which is strong in frontend and serverless functions but struggles with more compute-heavy backend workloads.
Render's Durable Workflows let developers resume long-running jobs after a failure without starting over, while Shared Filesystems enable sandboxes and workflow tasks to access the same persistent files. Render sees AWS and Vercel as the two platforms new users are leaving due to complexity and cost.
