The governed agent runtime and control plane for AI work#
AI agents are powerful — but deploying them into real workflows without guardrails is a liability. When an agent modifies data, commits code, sends a message, or triggers a workflow, you need to know what happened, who approved it, and whether it followed policy.
LumenFlow is the governed agent runtime and control plane that sits between AI agents and the actions they take. Teams often start with software delivery because it is the clearest enterprise wedge, but the same runtime also powers Sidekick and connected agents in other workflow domains. It enforces policy, routes risky work through approvals, and keeps an exportable evidence trail of everything.
Product map#
LumenFlow is one governed platform built around three jobs — Govern, Run, and Prove:
| What it does | Who it serves | |
|---|---|---|
| Govern | Set policy, route approvals, and cap budgets before any action runs | Platform teams, compliance |
| Run | Execute agent work under that policy — chat, workflows, connected runtimes | Everyone on the team |
| Prove | Capture evidence for every action and export it on demand | Compliance, engineering leadership |
Sidekick is the first-party client — the governed chat assistant most people use to Govern, Run, and Prove day to day. Teams that need deeper integration connect their own agents and runtimes to the same control plane through the SDK, so custom clients get the same policy, evidence, and approval guarantees Sidekick does.
What users can now do on LumenFlow Cloud#
Users can now create, launch, supervise, approve, recover, and audit multi-agent work from the cloud. Jobs is the workspace overview surface for launching and supervising governed work, while Agents shows the live job graph, safe actions, approvals, artifacts, and replay evidence.
In practical terms, teams can:
- launch governed Sidekick or agent jobs without spawning a local terminal process for supported flows
- approve risky actions from the workspace, mobile surfaces, or connected channel surfaces
- inspect who acted, what policy applied, what budget decision fired, and what replay evidence was saved
- connect external runtimes so existing agents report heartbeat, events, evidence, and health into the same control plane
- rely on durable worker scheduling for routines, hosted runtime launches, and wakeups rather than treating cron as the only progress mechanism
The product is still governed by workspace policy and rollout flags. LumenFlow does not grant agents unbounded access to tools or data; every connected action still runs through the configured approval, budget, evidence, and replay boundaries.
How it works#
| Layer | What it does |
|---|---|
| Policy | Define rules for what agents can do autonomously vs. what requires review |
| Approvals | Route risky actions through human or automated approval gates |
| Evidence | Every action is logged with full context — who, what, when, why |
| Export | Audit trails are exportable for compliance, review, and incident response |
Kernel and Cloud#
LumenFlow ships in two forms:
- Kernel — the enforcement layer that runs wherever your agents run, embedded in your development workflow. It validates agent actions against policy locally.
- Cloud — the hosted control plane that adds team visibility, approval routing, evidence storage, and export across your organization.
You can start with the kernel alone and add Cloud when you need cross-team governance.
Licensing#
The kernel, packs, and runtime are proprietary Hellmai Ltd software. You use them under the LumenFlow Proprietary License that ships with every package — the terms are included alongside the code you install, not published separately. The source is not published.
LumenFlow Cloud is a hosted service operated by Hellmai Ltd under the terms at /terms. Those terms cover your use of the hosted control plane; the package license covers the kernel, packs, and runtime you install.
Core principles#
- Policy before execution — agents propose, rules decide
- Evidence by default — every action produces a proof trail
- Human-in-the-loop where it matters — escalation for risky work, autonomy for safe work
- Open architecture — bring your own models, tools, and runtimes
info LumenFlow is in beta. We're building in public and shipping fast. Your feedback shapes the product.
