The agent runtime
you control.

An open-source daemon that governs, executes, and observes AI agents on your hardware. Explicit permissions. Process isolation. Full audit trail. No cloud.

Why this exists

OpenAI launched Frontier on Feb 5, 2026 — an enterprise platform managing AI agents as "AI coworkers." 57% of organizations now have agents in production (LangChain State of AI Agents, 2026). Every major vendor wants to be your agent runtime.

They share one assumption: your agents run on their cloud. Your data flows through their systems. Their policies govern your agents. OpenSentience inverts this — a supervised, local-first daemon where you define the rules.

Runtime governance is now table stakes

Palo Alto Networks, Token Security, and AccuKnox all confirm: agents need runtime identity, least privilege, and egress controls. "Governance has to operate at the same speed as the agents themselves." OpenSentience enforces at runtime.

The Sentient Foundation (Feb 19, 2026)

Launched to ensure AGI remains open-source and decentralized. OpenSentience embodies this at the infrastructure layer.

Architecture

An OTP supervision tree that manages agent lifecycles, permissions, and inter-agent communication. Every agent is a supervised BEAM process.

Admin UI
Phoenix LiveView — localhost-only dashboard. Real-time monitoring of every tool call, permission request, and resource access. localhost:4200 websocket
Agents
Supervised GenServer processes — memory-isolated, fault-tolerant, individually restartable. permissions resource limits audit log MCP tools
Protocol
MCP via Anubis (Hermes fork) — STDIO for local, Streamable HTTP for remote, Unix sockets for inter-agent. anubis_mcp 0.17+ JSON-RPC 2.0 OAuth 2.1
Daemon
OTP Application — fault-tolerant supervision with :rest_for_one strategy. One agent crash doesn't bring down the system. Elixir 1.17+ OTP 27
Storage
SQLite (state, audit, permissions) · ETS (hot cache). All data in ~/.opensentience/ — portable, inspectable, yours.

Core capabilities

Permission Engine

Fine-grained, per-agent capabilities. Filesystem, network, shell, MCP tools — nothing auto-granted. Users approve before activation.

Process Isolation

Every agent runs as a supervised BEAM process. Memory-isolated, fault-tolerant. One rogue agent can't crash others or read their state.

Audit Trail

Every tool call, file access, and network request logged. Full traceability, queryable via MCP or admin UI.

MCP Native

Agents expose and consume MCP tools. Connect to Claude Desktop, Cursor, VS Code. The protocol IS the API.

FleetPrompt Marketplace

Install agents with one command. Permission review before activation. Community trust scores and audit history.

Graphonomous Memory

Agents connect to Graphonomous for continual learning. Each agent gets its own knowledge graph that grows with use.
