Kedge

A full-stack cloud with forkable VM snapshots and global SQLite, deployable over SSH or Git.

Kedge is a cloud for deploying websites, functions and container images over SSH or Git; its Show HN in July 2026 (141 points) pitched forkable VM snapshots and global SQLite, features that suit agents which need disposable, branchable machines.

E2B

Open-source sandboxes for running AI-generated code.

E2B gives agents secure, isolated cloud micro-VMs to execute code and commands — the execution runtime layer of the harness, used by many coding and data-analysis agents.

Elastic sandboxes for running AI-generated code.

Daytona provides secure, OCI-compatible sandbox 'computers' that spin up in under 90ms — with snapshots for persistent agent state. In 2026 it moved core development to a private codebase while continuing to run as a commercial platform.

Serverless cloud built for AI and agentic compute.

Modal lets teams run inference, fine-tuning and arbitrary agent workloads as serverless Python without managing infrastructure — a common substrate for harness backends at scale.
