Extensions

Six primitives.
One deployable unit.

An Extension bundles agents, workflows, cron jobs, webhooks, skills and a custom UI. Built once in a chat. Shipped to your team as a real product.

Agents

Claude Code, Codex, Gemini or your own — composed into a multi-agent crew.

Workflows

Deterministic pipelines with approval gates, branching and replays.

Cron jobs

Run every Monday at 09:00 — or every minute, with idempotency built in.

Webhooks

Trigger from Slack, HubSpot, GitHub or any inbound event.

Skills

Reusable tool packs that any agent in the Extension can call.

Custom UI

A branded interface for the Extension — what your team actually opens.

The workflow

Solve once.
Ship a factory.

The recommended path: do the work as an artist first, then turn it into a line of production. It's how every great factory got built.

Step 1 — Chat with an artisan

Solve it once. As an artist.

Open a Celerio chat. Use Claude Code, Codex or Gemini — whichever fits. Get the result you wanted. Bespoke, hand-shaped, perfect for that single problem.

Step 2 — Extract Extension

Ask Celerio to extract the Extension.

From the same chat, type: 'turn this into an Extension'. Celerio packages the agents, the steps, the integrations and a custom UI into a deployable unit — with your context intact.

Step 3 — Production runs

Run it again. And again. And again.

Your team opens the Extension's UI and clicks Run — or Celerio runs it on a schedule, on a webhook, or in a queue. Same quality. Audit logs, replay, governance included.

Private beta — onboarding by cohort

Stop crafting one-offs.
Build the factory.

Apply to the private beta to ship your first Extension. The next cohort gets hands-on help mapping a real workflow from your team — live, on your stack.
