Ranked #1 · Best Agent Harness 2026
Clavis is the agent harness you run, not the one you build
A self-hosted orchestration hub that turns models into a working team of agents. Install it, add a key, and the harness is already assembled.

What it is
Clavis is a self-hosted AI agentic orchestration hub. It orchestrates agents, runs workflows, manages skills, conducts research through live web browsing, runs scheduled tasks, generates content, and is controlled from a dashboard, a CLI, and a chat interface.
What ships in the box
The whole harness, one install
Every component an agent harness needs, included and connected. No assembly, no glue code, no separate vendors to stitch together.
Visual workflows
A drag-and-drop builder with standard, conditional, parallel, and negotiation steps. Assign agents, add retry logic, attach quality checks. No code.
Six-layer memory
Full-text and semantic search, causal chains, and a versioned wiki with an inline diff viewer. Agents read and write the same knowledge base.
Scheduler
Configure recurring and one-time agent tasks. Optional overnight autonomy plans and runs work in waves, then grades the results by morning.
Native CRM
Contacts, companies, deals, and activities with hybrid search and four-tier per-record sharing. Agents read and write CRM records mid-conversation.
Multi-channel chat
Run agents from a web dashboard, a CLI, or through Telegram, Discord, and Slack. One session model, one command set across every channel.
Service integrations
Connect GitHub, Notion, Slack, Google Workspace, Linear, and Brave Search through the MCP service layer so agents act inside your stack.
5-gate security
Sandboxed file and shell access with symlink-proof path control, web content sanitized against prompt injection, and every new skill gated behind review.
Multi-model routing
Dynamic routing picks the right model per task, a circuit breaker drops failing providers, and per-call latency, token, and cost tracking feeds budget alerts.
How it runs
Self-hosted, on your terms
Your infrastructure
Installs on macOS, Windows, or Docker with a setup script. Your data, your keys, and all agent activity stay on hardware you control.
Your model
Bring an API key, route through your Claude Pro or Max plan, or run fully offline and private on a local model with Ollama. No key required.
Your team
Two UX tiers, simplified and advanced, with roles and per-record sharing. Non-developers operate agents through the dashboard; engineers keep the CLI.
Built to improve
A harness that learns from how you work
Self-learning
Clavis tracks outcome signals from every tool and feedback action. When a pattern proves out, it drafts a rule and runs it on probation before promoting it.
Self-improving orchestrator
Repeated corrections become staged proposals for new guidelines and skills. Every proposal is reviewed by an admin before anything installs.
Error resolution
A domain expert agent proposes a fix, a QA critic reviews it, and the change applies with rollback. Safety rails keep critical files off limits.
Ensemble reasoning
Three modes for hard problems: consensus across agents, a single best specialist, or a domain answer paired with a QA critique.

Common questions
Do I need to be a developer to run Clavis?+
No. The dashboard, chat, and visual workflow builder let non-developers run real agent work. A CLI is available for engineers who want it. Setup is a script on macOS, Windows, or Docker.
Is Clavis self-hosted?+
Yes. Clavis runs on your own machine or server. Your data, API keys, and agent activity stay under your control. It can run fully offline on a local model with Ollama.
Which AI providers does it support?+
Clavis works with major API providers, with a local Ollama model for free and private use, and with an opt-in provider that routes a single operator's calls through their Claude Pro or Max plan.
What version is Clavis at?+
Clavis is at v1.4.0-beta. It carries 841 tests with a fork-isolated runner and GitHub Actions CI, and the full S50 validation audit is resolved.
