Most open-source agent platforms optimize for convenience and treat isolation, policy, and audit as things you add later. xFrontier inverts that order. It is a uniquely built runtime, not a fork or a wrapper, where enforcement is wired into execution itself, so every agent, every tool call, and every handoff happens inside a boundary you define and can prove after the fact.

/01Governed Alternative

The Governed Alternative to Convenience-First Agents

xFrontier is a runtime for building, deploying, and operating AI agent workflows that an organization can stand behind. It is built from first principles around local-first execution, enforced security, and data-centric control rather than retrofitted onto a platform designed for scale and ease.

01

First-Principles Design

xFrontier was not assembled by wrapping an existing agent framework. The orchestration, guardrails, execution, and infrastructure layers were designed together so that governance is a property of the runtime, not a policy document that operators are trusted to honor.

02

OpenClaw-Class Ergonomics

Teams get the multi-agent ergonomics they expect from a modern agent platform: role-based agents, structured handoffs, durable workflows, and a tool ecosystem. The difference is the substrate underneath, which is built to be isolated, scoped, and audited.

03

Data-Centric Control

Control follows the data and the action rather than the network perimeter. Sensitive content is masked before it reaches a model, tool access is bound to the invoking agent, and outputs pass through policy before they leave the boundary.

/02Enforced Isolation

Three-Tier Sandbox, Auto-Detected

Agent code never runs in the host process. It runs inside a hybrid sandbox that detects the strongest isolation available in the current environment and selects it automatically, so the same agent is contained on a laptop, a Docker host, and a Kubernetes cluster without manual configuration.

Sandbox TierTier 1 / Kernel
Mechanismbubblewrap and seccomp on Linux, seatbelt on macOS
When UsedDefault on a developer machine where Docker is absent. Isolation is enforced by the host kernel with roughly one millisecond of startup overhead.
Sandbox TierTier 2 / Hardened Docker
MechanismContainer with full capability drop and a read-only root filesystem
When UsedSelected when a Docker daemon is present. Each agent runs in a stripped container that cannot acquire new privileges or write to its own image.
Sandbox TierTier 3 / gVisor or Kata
MechanismKubernetes RuntimeClass binding to a gVisor or Kata sandbox
When UsedUsed for cluster deployments that require a user-space kernel or lightweight virtual machine boundary around untrusted agent code.
/03Capability Governance

Authority in xFrontier is carried by the agent, not assumed by the runtime. Every agent invocation presents a signed Biscuit capability token that encodes the exact tools it may call and the budget of calls it is allowed. The token is verified before execution and can be attenuated on handoff, so a delegating agent can only narrow the authority it passes on, never widen it. Open Policy Agent evaluates each tool call and routing decision against declarative policy, which keeps authorization rules out of agent code and under version control.

TOKEN AND POLICY CONTROLS

  • Signed Biscuit tokens encode per-agent tool allowlists and call budgets.
  • Tokens attenuate on handoff, so delegated authority can only shrink.
  • Open Policy Agent gates every tool call and routing decision.
  • Verification runs before execution, not as an after-the-fact log entry.
/04Tiered Memory System

A Governed Memory Subsystem, Not a Bolted-On Vector Store

Memory in xFrontier is a uniquely built, first-class subsystem rather than a single vector store appended to a prompt. It is tiered across three stores, each chosen for a distinct role, and the tiers cooperate through a consolidation pipeline that summarizes raw events into durable knowledge and suppresses duplicates. Hybrid retrieval then blends short-term, long-term, and graph context under explicit ranking and token budgets.

Every memory is scope-aware. Each entry is bound to a run, session, user, tenant, agent, workflow, or global scope, and authorization is enforced on recall. An agent never retrieves a memory it is not entitled to read, which makes the memory layer itself a governed boundary rather than a shared bucket.

Memory TierShort-term working memory
StoreRedis session cache with an optional write-ahead log
RoleHolds the active context of a run so agents share state within a session without persisting transient detail to durable stores.
Memory TierLong-term semantic memory
StorePostgreSQL with the pgvector extension
RoleStores consolidated knowledge for semantic recall, so agents retrieve past findings by meaning rather than by exact match.
Memory TierWorld-graph memory
StoreNeo4j property graph
RoleProjects topics, relationships, and evidence links as a graph, letting agents reason over structured connections instead of nearest-neighbor text alone.
/05Auditable by Design

Signed, Replayable Event Chains with Human Gates

Audit in xFrontier is a runtime guarantee rather than a reporting feature. Every meaningful event is written to a cryptographically signed chain that supports full replay, so an operator can reconstruct exactly what each agent did, in what order, and under which authority. Sensitive operations sit behind human-in-the-loop gates that require explicit approval before an agent proceeds.

01

Signed Event Chain

Each event is appended to a cryptographically signed chain. Tampering breaks the signature, so the record is verifiable evidence rather than a mutable log that an attacker or a buggy agent could quietly rewrite.

02

Full Replay

Because orchestration state is checkpointed and events are ordered, a run can be replayed step by step for incident review, debugging, or compliance evidence without re-executing the original side effects.

03

Human-in-the-Loop Gates

High-impact actions pause for operator approval. The gate decision is itself recorded in the event chain, which ties accountability for a sensitive step to a named approver rather than to the agent alone.

04

Signed Skills Registry

The skills registry is signed and provenance-checked, so only vetted capabilities reach the runtime. An agent cannot pull in an unverified skill at execution time and expand its own reach.

/06Local-First and Open Source

xFrontier is local-first by default. Data stays on your network unless you explicitly configure otherwise, and the platform can run fully disconnected for air-gapped operation. It bridges to local models through an Ollama OpenAI-compatible endpoint with a curated allowlist, so teams run capable agents with no API keys and no cloud inference. Because it is released under the GNU Affero General Public License v3.0, organizations can inspect, self-host, and extend the entire stack, and there is no opaque control plane to trust.

DEPLOYMENT CONTINUUM

  • Local profile: a lightweight setup for development on a single machine.
  • Secure local profile: the full gateway, policy, and sandbox stack with OIDC operator authentication.
  • Hosted Kubernetes profile: Helm deployment with gVisor or Kata isolation for enterprise rollout.
  • One codebase carries the same stack across all three profiles with no re-platforming.
/07Where Teams Run It

Operational Outcomes

xFrontier suits teams that want modern agent ergonomics on infrastructure they can govern, isolate, and audit. The following patterns show where the runtime guarantees translate into operational outcomes.

Governed Engineering Agent Teams

Run multi-agent software-engineering workflows where each agent operates inside a sandbox under a scoped capability token, so generated code and tool calls stay bounded and reviewable.

Internal DevOps Automation

Drive build, deployment, and remediation tasks across internal networks while Open Policy Agent gates every tool call and Envoy bounds outbound traffic at the egress boundary.

Air-Gapped Agentic Workflows

Operate fully disconnected with local models served through the Ollama endpoint, keeping data and inference on owned hardware with no external API dependency.

Approval-Gated Sensitive Operations

Insert human-in-the-loop gates ahead of high-impact actions so an operator authorizes the step before an agent proceeds, with the decision recorded in the signed event chain.

Long-Running, Resumable Jobs

Checkpoint multi-agent workflows in PostgreSQL through LangGraph so a job resumes from its last committed step after interruption rather than restarting from the beginning.

Because isolation, capability scoping, signed audit, and scope-aware memory are runtime properties, xFrontier maps cleanly onto agentic-AI control expectations and zero trust principles. The frameworks below describe the controls the runtime is built to support.
