Your expertise,supercharged by an agentic core.
Arche connects your knowledge, your tools, and a team of specialized agents — so the grind dies and your team ships.
Your decisions are irreplaceable.
Your execution shouldn’t be.
AI doesn't replace the people who think. It replaces the part of their day they were never meant to do.
01·The glue
Stop being the glue.
You found what AI can do — and now you spend your day shuttling prompts between Claude, Cursor, ChatGPT and a Notion doc. Arche runs underneath all of them. You decide. The core executes. The copy-paste disappears.
02·The silos
Your team's best prompts shouldn't live in DMs.
Every teammate hoards their own skills, prompts and shortcuts. Nothing gets shared, nothing compounds. With Arche, skills and processes are versioned, monitorable and shared — what one person figures out on Tuesday, the team is using on Wednesday.
03·The lock-in
Your stack is yours. Not a vendor's.
Today's best model becomes next month's overpriced one. Open-source, multi-model, multi-provider — Arche is the only layer that doesn't expire. The right model routes to the right task. Your expertise, your data, your processes — yours to own.

Open source
We are building this in public because this needs to exist.
Arche is free and open source because we believe there should be a tool anyone can use without being trapped inside a single provider’s product roadmap, pricing, or API terms.
The goal is simple: make these technologies available on your own terms. Self-host it, choose the models you want, keep your workflows portable, and make sure the system stays useful even as providers change.
No dependency on a single provider to access core workflows.
A tool any team or individual can run, study, and adapt.
A shared foundation the community can improve together.
Frequently asked questions
Yes — Arche is fully open-source. There are no hidden tiers, usage limits, or premium features behind a paywall. You only pay for the AI model providers you choose to connect.
ChatGPT and Claude are individual chat interfaces tied to a single provider. Arche adds a layer on top: it's multi-provider, multi-user, and can run in the cloud or locally. It's designed to be an agnostic hub where your team works with the best models available — sharing processes, agent configurations, skills, and knowledge in one place.
Obsidian and Notion are great for writing and organizing notes. Arche goes further: your documentation becomes a living, version-controlled knowledge base that AI agents actively use to execute tasks — not just store information.
Not yet, but we're actively working on adding Ollama compatibility to enable fully offline usage. Stay tuned.
Absolutely. Self-hosting is the default. Deploy on your local machine, on-prem servers, or a private cloud with a single command.
Arche supports OpenAI, Anthropic, Fireworks, OpenRouter, and OpenCode as providers. You can route different experts to different models instead of locking the whole workspace into one vendor.
Arche is designed to follow security best practices whether deployed remotely or running locally. That said, the actual security of your deployment depends on how it's configured — especially for remote setups, make sure you have the knowledge to deploy it properly and avoid leaving gaps. For local use with Arche Desktop, your data stays on your machine with no extra risk.
To try the Desktop version — no. Just download the DMG and start using it. To self-host on your own infrastructure, some technical knowledge is recommended, though following the guides should get you there without major issues.
The Desktop version is single-user. The self-hosted remote version supports multiple users, each with their own isolated workspace, so teams can work in parallel without conflicts.
Arche is open-source. Your instance, your data, and the entire codebase are yours. Even if active development stops, everything keeps running on your infrastructure.
