LoopX is an open-source, provider-neutral state kernel and local-first control plane for long-horizon AI agents and peer agent teams. It runs on top of agent harnesses such as Codex, Claude Code, Cursor, dsh, or a custom harness rather than replacing them, keeping objectives, gates, tasks, evidence, quotas, schedules, recovery state, and handoffs durable across bounded turns, sessions, tools, and agents. Its control layer makes semantic decisions about what happens next and supports governance, recovery, human-agent collaboration, and reviewable work. The accompanying personal agent workspace stores goals, attention, conversations, tasks, files, schedules, and recovery state locally across restarts; its supported browser/PWA dashboard can continue work across registered agent sessions and use typed previews, explicit confirmation, and receipts for protected changes.

Agent Substrate is an open-source runtime and control plane for running agent-like workloads at high density. It manages the lifecycle of sandboxed actors, including creation, destruction, suspension, and resumption, and assigns them to a smaller pool of worker pods while routing traffic to the active workers. The system uses Kubernetes for infrastructure provisioning and pod lifecycle management, with support for sandbox technologies including microVMs and gVisor. It preserves actors' volatile memory and filesystem state through full-state snapshots, enabling sub-second suspend and resume operations and multiplexing many stateful actors across shared infrastructure. It manages standard OCI containers at the kernel level and is designed to support different agent frameworks and harnesses, including ADK-compatible actors, LangChain agents, coding environments, and MCP servers. Agent Substrate is intended for running agents at scale rather than building them, and its workloads do not have to be literal AI agents. The repository notes that the project is not an officially supported Google product.

Blaxel is an infrastructure platform for autonomous AI agents that provides isolated microVMs (which boot in milliseconds and resume in ~25ms), persistent shared memory, and programmable networking to run, connect, and operate agents at scale. It offers a distributed shared-storage feature (presented in videos as "Agent Drive") that can be mounted as a POSIX-style drive so agents in separate sandboxes can share files, cache dependencies, exchange context/memory, and coordinate parallel work in real time.

AgentOps is an open-source observability and developer-tools platform for building, evaluating, and monitoring AI agents. Its Python SDK records agent sessions and LLM calls for dashboard-based session replays, step-by-step execution graphs, debugging, analytics, cost tracking, and benchmarking. Developers instrument code with decorators for sessions, agents, operations, tasks, and workflows; these support nested span hierarchies, input and output recording, exception handling, asynchronous functions, generators, and custom attributes. The SDK provides integrations with agent frameworks and LLM systems including CrewAI, AG2/AutoGen, Agno, LangGraph, and the OpenAI Agents SDK, and the platform can be self-hosted with its dashboard and API backend. The app is released under the MIT license.

useAgent is an open-source AI coworker that gives Claude Code, Codex, OpenCode, and Pi a shared workspace with isolated Linux computers, repositories, terminals, browsers, and team tools. It can handle research, websites, spreadsheets, reports, presentations, and code changes, returning usable files, artifacts, or pull requests through a web app, Slack, REST API, or scheduled tasks. Each run is stored as an event log in Postgres and uses a common event contract across supported agent engines. Daytona or CubeSandbox provides the isolated workstation, while integrations cross a trusted gateway as typed tools so credentials remain on the control plane rather than entering the sandbox. The workspace also supports versioned skills and playbooks, team knowledge and memory, approval-gated tools, revisioned workpieces, and durable sessions. The repository describes useAgent as alpha software with changing APIs and schemas. It can be self-hosted on Linux using Bun and Postgres with pgvector, and is licensed under AGPL-3.0-only; a commercial license is available for proprietary embedding, distribution, OEM, or white-label use.
