A PANTHEOS FORGE PRODUCT

Describe the expert. Janus builds it, tests it, ships it.

Most AI agent builders hand you a blank canvas and a pile of glue code. Janus is different: it's an agent whose specialty is making other agents. Tell it what expert agent you need in plain language — it interviews you, builds the agent, proves it actually works, and hands you a self-contained, runnable product. No coding required.

Plain language

Describe the agent you want — no glue code, no framework wiring

Fails honestly

Can't meet its quality bar? Janus ships nothing and tells you why

5 backends

Anthropic, Claude Code, OpenRouter, local models, DeepSeek-style

Runs anywhere

Each agent bundles its runtime — laptop, server, or container

The Build Flow

One command, one conversation

Seven steps from a plain-language description to a self-contained agent you can run.

Clarify

Focused questions pin down the spec — it doesn't guess

Research

Grounds the design in what the task actually needs

Approve

Presents a spec — nothing builds until you sign off

Scaffold

Generates the agent as declarative files

Validate

Runs it for real; an AI judge scores it on a rubric

Fix

Up to 3 automatic improvement passes if it falls short

Export

Ships a self-contained repo you run anywhere

What Makes It Distinctive

An AI agent whose specialty is
making other agents.

Not a canvas, not a framework. An AI agent builder with a quality gate.

◇

No-code definition

An agent is a directory of declarative files — identity, instructions, tools, output format, and a quality rubric. Zero code changes.

✓

Built-in quality gate

Every agent passes a smoke-test run plus an LLM judge before it's done. Quality enforced, not assumed — a broken test scores zero.

⎇

Tool-equipped agents

Agents can be containerized to run real command-line tools — scanners, data CLIs — and Janus builds and tests that image for you.

⟳

A managed fleet

Built agents live in a fleet you run, re-validate, improve in place, and sync core upgrades across. A lifecycle platform, not a one-shot generator.

Proven where it counts

Janus was extracted from a real, in-production pentesting agent. Pentesting was the first agent built this way — the template proved itself on a hard, high-stakes domain before becoming a general product. That's a credibility story, not a demo.

Two Ways To Build An Agent

AI agent builders give you a canvas.
Janus gives you a finished agent with a quality gate.

The market is full of frameworks and no-code canvases that leave the hard parts — grounding, testing, packaging — to you.

The usual way

Start from a blank canvas and wire up framework glue code
Hand-engineer prompts, tools, and output formats yourself
Hope it works — testing and evaluation are on you
Package, containerize, and deploy each agent by hand
Locked to one vendor's model and runtime
Every new agent starts the whole cycle over

The Janus way

Describe the expert in plain language — the architect interviews you
Identity, tools, and output generated as declarative files, no code
Validated before it ships — smoke test plus an LLM judge on a rubric
Exports a self-contained repo that runs anywhere, container included
Run an AI agent on any model backend — five interchangeable options, not locked to one vendor
Agents live in a managed fleet with sync-able core upgrades

Category Positioning

How Janus compares

Janus is the only approach that treats agent-making as a specialty, enforces a quality gate, and refuses to ship anything that doesn't work.

Capability	Framework SDKs	No-code canvases	Janus
Build an agent without writing code	—	✓	✓
Interviews you to pin down the spec	—	—	✓
Grounds design in task research	—	partial	✓
Built-in quality gate (test + LLM judge)	—	—	✓
Refuses to ship a failing agent	—	—	✓
Self-contained, portable export	partial	—	✓
Runs real CLI tools in containers	DIY	—	✓
Vendor-neutral (5 model backends)	varies	—	✓
Managed fleet + sync-able upgrades	—	—	✓

The differentiator competitors can't fake

Janus builds an AI agent that fails closed. If it can't meet its quality bar after up to three automatic fix attempts, Janus exports nothing and tells you why, with real scores. You never get handed a broken agent that's quietly called “done.”
