Firecracker is an open-source microVM monitor for running lightweight virtual machines with container-like density and stronger isolation. AWS built it for multi-tenant services such as Lambda, and the project also highlights managed Lambda MicroVMs for sandboxed compute.
Platform engineers building secure multi-tenant runtimes or evaluating microVM isolation for serverless and agent sandboxes.
Production hosting costs depend on your cloud provider; Firecracker itself is infrastructure software without vendor SaaS plans on the project site.
Firecracker packages KVM-backed microVMs that aim to combine VM-level isolation with the speed and efficiency teams expect from containers, with optional managed Lambda MicroVM offerings for serverless sandboxes.

cmux is a free, open-source macOS terminal built on Ghostty for multitasking with AI coding agents. It adds vertical tabs, split panes, notification rings, an in-app browser, and optional cloud VMs on paid plans for remote agent sandboxes.
Explore toolAgentMail is an email inbox API built for AI agents, giving each agent its own inbox to create threads, send and receive mail, handle attachments, and integrate via SDKs or MCP. The product targets developers wiring agents into real email workflows with multi-tenant controls and optional custom domains.
Explore toolCerebrium is a serverless GPU platform for deploying real-time AI workloads such as voice agents, video models, and LLMs with sub-second cold starts and elastic scaling. Teams run Python apps on managed GPUs across multiple regions and pay for compute by the second rather than reserved capacity.
