Hosted multi-agent orchestration

Run your agent fleet in production without babysitting it.

Nexus schedules a dependency DAG of agents, runs ready work in parallel, and supervises every worker with evidence — heartbeats, not wall-clock guesses. It auto-recovers stalls in seconds, pauses for a human when a decision is needed, and stops a runaway before the token bill does. Hosted — you ship the workflow, we run the supervisor.

Free live demo — no login, no credit card. Hosted Nexus is set up with you on a call.

DAG schedulingDeclare dependencies; ready work fans out in parallel. Cycles are a build-time error.
Evidence-based recoveryStale heartbeat → suspected → confirmed → retried. A 3-second stall detect, on evidence.
Human-in-the-loopA worker that needs a decision blocks and asks. The run stays alive until you answer.
Token-cost governanceEvery task's budget is reserved before dispatch. A runaway stops before the bill.

Nexus in 66 seconds — narrated

Why agent fleets fail in production, what Nexus does about it, and how one goal becomes a supervised nine-agent run — with a failure recovered and a human decision answered along the way. Then run the real thing below.

The runtime

Five mechanisms most agent stacks are missing.

The supervision pattern behind a production fleet of 40+ services — extracted, hardened, and hosted.

One goal in — nine agents, run in parallel.
The stall that fixed itself — evidence, not timeouts.
A runaway stops at its budget — not on your invoice.

Each mechanism, in under 20 seconds — narrated, with captions. Want proof instead of pictures? The live demo below runs the real engine.

First, watch a real supervisor run a plan

Press Run the live demo. This is the actual Nexus runtime scheduling nine agents to “ship a feature” — every box and every line in the stream below is a real decision streamed live from the engine to your browser. It fans out parallel work, hits a failure and recovers it, and pauses to ask you a question.

The plan, as a live map

idle

What am I looking at? Each box is an agent doing one step. Each arrow is a dependency — a step only starts once everything pointing into it has finished. The colour of a box is its state right now:

queued (waiting on dependencies) running now waiting for your decision done failed & retrying cancelled

Real workflow shapes Nexus runs — free to explore.

Every card is a real dependency DAG the runtime schedules. No login, never empty. See how parallelism, recovery, blockers, and budgets play out — “Ship a feature” runs live above.

Now, pick your mission

You just watched the real engine run. Here’s how that same pattern maps onto work you actually care about. Choose a scenario and we’ll sketch the team of agents we’d assemble for it — who does what, and what waits on what.

Hosted

Ship the workflow. We run the supervisor.

This is the hosted console, simulated end to end in your browser: configure a project, then watch supervisors provision, heartbeats arm, a stall recover on retry, a runaway clamp at its budget, and a human gate pause the run for your answer. Book a call and we run exactly this for your team.

The run is asking you a question

How hosted Nexus works

From your DAG to a supervised run in four steps.

1

Declare the DAG

Tasks + dependencies + a token budget each. Cycles and unknown deps are rejected at build time.

2

Deploy hosted

We spin up managed supervisors. Your Worker plugs into any agent, subprocess, or HTTP job.

3

Supervised run

Ready work fans out in parallel; heartbeats prove liveness; stalls are confirmed and retried; blockers wait for a human.

4

Stream & govern

Every decision lands on the event stream; budgets settle after each task; a runaway stops before the bill.

Why this matters to you

Hand a single AI a job with twenty steps and it can fail silently at step seven — the answer still looks finished. An orchestrated team with a supervisor watching every step doesn’t work that way. Three ways that plays out:

A research report

Several agents gather sources, pull data, and draft sections at the same time, then a final agent merges them into one coherent report — instead of one agent grinding through sources in sequence for an hour.

A lone AI drops a source and never notices. Here every branch is tracked to done.

A content pipeline

Drafting, editing, and quality-check run as coordinated steps: editing can’t start until the draft is done, QA can’t sign off until edits land — and if a step wobbles, it retries rather than shipping something half-baked.

No more “it edited a draft that was never written.” Steps wait for what they depend on.

An audit, fanned out

One review is split across departments — each handled by its own agent in parallel — then all the findings are merged into a single verdict, with a human sign-off gate before anything is finalised.

Nothing gets rubber-stamped in the dark. You approve the decision that matters.
The difference in one line: one AI doing twenty steps fails silently at step seven. An orchestrated team with a supervisor detects the stall, recovers it, asks you when it needs a decision, and reports exactly what finished and what didn’t.

Nexus vs Workflow Master — which one do you need?

Two different jobs. Most teams eventually want both.

Two tools, two jobs

Nexus orchestrates teams of AI agents executing dependency-aware plans. Workflow Master automates your business tools — CRM, email, social, voice — with deterministic when-this-then-that pipelines. Orchestrate AI work with Nexus; automate your operations with Workflow Master.

Done for you

We build the fleet into your operations — you get the outcome

We design your agent DAG, wire it into your systems and data, and run the supervisor for you. What you get is an agent fleet working your operations around the clock — with human gates exactly where they matter.

Runs your operations 24/7

Work that took a team of coordinators — research, content pipelines, audits — happens autonomously and in parallel, without anyone babysitting it.

Never fails silently

Every branch is tracked to done. A stalled worker is detected, recovered, and retried — instead of one agent dropping a step at 2am and no one noticing.

Human gates where they matter

The fleet pauses and asks you at the decisions that count, and stops a runaway before the token bill does. You stay in control; the machine does the grind.

An honest engineering note. The live demo above is a self-contained live demo — the agents are simulated (no external calls), but the scheduling, supervision, retry, human-approval, and budget machinery is the exact production runtime. The hosted-console walkthrough is a browser simulation of the hosted experience, labeled as such. The mission previews are illustrative sketches of the team we’d assemble. The same supervisor pattern is deployed in production systems on this portfolio.
