The company maps three waves — copilots for code completion, then agents that built full web applications, and now a third wave of agents controlling entire computers for long-running tasks. What those agents need, E2B says, is not a bigger sandbox but an 'agent-driven private cloud': infrastructure with dedicated storage, firewalls, and networking between sandboxes that adapts to each agent's resource and tool requirements. The claim is backed by scale — E2B says it has processed billions of agent runs and generated tens of billions of traces, enough to predict an agent's tool usage and resource consumption before execution. The sandbox was built for code snippets. The agent now wants a machine, a network, and a future.",

Most telling is the Image Export detail: the exported app does not need to communicate back to the Replit platform at all. The platform is learning to sell itself as software you run, not a service you visit — because enterprise agents cannot live on someone else's cloud.",

Its VM Sandboxes, built for what it calls sophisticated agentic workloads at scale, were being choked by the filesystem: under the old virtio-fs stack, a recursive chown took over a minute versus four seconds natively, with every operation requiring round trips from guest VM to host. The new ImageFS-blk moves to a block-device approach that keeps metadata operations inside the guest kernel — chown dropped from 9.87 seconds to 0.21, and a bun install benchmark fell from 12.5 seconds to 1.07, while containers still cold-start in under a second. When agents install packages, traverse trees, and hammer the filesystem thousands of times per run, the filesystem is not a detail. It is the product.",

Its CI bill was $3,990 in June, $10,778 in July, and $18,200 in August — driven, the company says, by AI-driven development: the Logfire team merged 2,032 pull requests in August 2026, versus 365 in the same 30 days in 2025 for a same-sized team. Runner minutes kept rising even after the fix, from 1.23M to 1.62M between August and September. Moving CI to RunsOn on September 1 — ephemeral EC2 runners in Pydantic's own AWS account, Graviton for most jobs, spot where retries are cheap — brought the September bill down to $5,700. This suggests the real story of agent infrastructure is cost control, not just capability: agents multiply work faster than they multiply budgets, and the companies that survive the transition will be the ones that re-engineer the substrate — the cloud tenancy, the filesystem, the runner fleet — around the agent as the unit of compute.",
