Eon

Eidos is a private, self-hosted file-search system that lets users search across computers, servers, virtual machines, archives, and network storage without first remembering where a file is located. The project is Windows-first and catalogs NTFS and SMB sources, indexing file names and contents while retaining stale results when sources go offline. Its intended design connects file identity, location, freshness, related copies, and surrounding context without moving files into a vendor cloud or separate repository. The README describes the project as under active development: several capabilities remain planned, APIs, schemas, and query syntax may change, and no packaged release is available yet.

E2B is open-source cloud sandbox infrastructure for securely running AI-generated or user-specific code, tools, and agents in isolated environments. Sandboxes can be started and controlled through JavaScript/TypeScript or Python SDKs, supporting command execution, code interpretation, desktop interaction, sandbox templates, and snapshots that preserve a running environment's filesystem and memory for pausing and resuming. The platform manages sandbox lifetimes, idle timeouts, workspace assignment, runtime filesystem writes, storage, orchestration, and network restrictions. It can be self-hosted using Embed deployment and Terraform on AWS, Google Cloud, Azure, or a general Linux machine.

AgentENV (AENV) is an open-source distributed platform developed by kvcache-ai for running agent environments at scale, including environments used for agentic reinforcement-learning training such as Kimi K3. It runs Firecracker microVM sandboxes across machines, loads OCI-compatible images on demand through overlaybd, and uses local disks as bounded caches for image and snapshot data. The aggregate image and snapshot footprint can exceed local disk capacity because cold data is evicted from the cache. Snapshot-backed environments can boot or resume in under 50 ms and pause in under 100 ms. AENV incrementally snapshots memory and filesystem changes, stores snapshots in S3-compatible object storage or a shared distributed filesystem, and can fork a running environment into independent sandboxes for parallel workflows. It uses ublk for I/O and memory ballooning to return reclaimable guest memory to hosts; the documentation reports a 9.6× memory overcommit ratio in production. The distribution includes an AENV server and the `aenv` command-line client for pulling OCI images as templates, starting, attaching to, executing commands in, pausing, resuming, and deleting sandboxes. It exposes an E2B-compatible HTTP API that works with the standard E2B Python and TypeScript SDKs. It requires Linux kernel 6.8 or later and `/dev/kvm` access for Firecracker execution. API requests are authenticated, but traffic is not encrypted; the documentation recommends a trusted network or HTTPS termination at a reverse proxy or load balancer.
