The Arch Your
Agents Stand On
Arco is the infrastructure layer beneath autonomous agents — memory, automation, and on-chain perception, engineered like a Renaissance arch: load-bearing, precise, built to outlast whatever gets painted on top of it.
Three Pillars,
One Arch
Memory
Every project, preference, and past fix is written to durable storage and retrieved by relevance, not by keyword.
Automation
Natural-language jobs run unattended on a real scheduler — no cron syntax, no polling, no babysitting.
On-Chain Perception
Wallets, contracts, and mempool activity stream in as first-class signals an agent can reason over.
Every Fresco Has A Frame
The duotone is the surface. Underneath it a scheduler, a model router, and a memory store are doing real, measurable work — every second, across every agent we host. Nothing below is a mockup; it's what the studio floor actually looks like.

Perceive. Reason. Act. Remember. Repeat.
Perceive
Every message, file, webhook, and on-chain event lands in one ingestion loop — normalized, timestamped, and ranked before an agent ever sees it.
40+ connectors liveReason
A router scores the task and picks the cheapest model that can actually do it, escalating up the chain only when confidence drops.
12 model providersAct
Tool calls run inside a sandbox tier matched to the risk — read-only, write-scoped, or fully isolated — before anything touches a live system.

Outcomes compress into durable memory and get indexed, so the next run starts already knowing what the last one learned.

Six Studies, One Fresco
Lives Everywhere
Telegram, Discord, Slack, WhatsApp, terminal — one agent, one memory, every surface.
Persistent Memory
It learns your projects, auto-generates skills, and never repaints over what it already solved.
Disciplined Automation
Natural-language scheduling for reports and briefings, running unattended, on time, every time.
Tasks Multiplied
Isolated subagents with their own conversations and tools, for zero-context-cost pipelines.
Browse The Web
Web search, browser automation, vision, and multi-model reasoning, called on as needed.
Isolated Sandboxing
Sandboxed runs — local, Docker, or remote — kept apart from the rest of the studio.
"We did not want a dashboard. We wanted a studio — somewhere an agent could apprentice, make mistakes on scrap canvas, and eventually paint something you'd hang on the wall." — from the Arco manifesto
Built In The Open
Arco ships as source, not a service. Clone it, read every line, fork the studio, or send a patch — there's no paywall between you and the code.
