Multi-agent AI, in your browser

Create & run multiple AI agents that work together.

Design custom agents with their own prompts and models, then chain them into crews — researchers, writers, critics — that build on each other's work in rounds.

No credit card required · Free tier includes 3 agents

Everything you need to ship with agents

From a single agent to a full crew — with accounts, billing, and per-user isolation built in.

Custom agents

Name, system prompt, model, and temperature per agent. Works with any OpenAI-compatible LLM — OpenAI, Groq, OpenRouter, Ollama.

Crew runs

Select multiple agents, set rounds, and they work the same task in sequence — each sees every previous response. Perfect for research → draft → review loops.

Streaming & history

Token-by-token streaming replies. Full conversation history per agent, saved crew runs, and one-click replay.

Accounts & isolation

Signup/login with hashed passwords. Every user's agents, chats, and LLM keys are fully isolated — never visible to others.

Built-in billing

Stripe Checkout + webhooks ready. Free/Pro/Enterprise tiers with daily quotas that auto-reset. Upgrade in one click.

Self-host ready

Single Node.js process, JSON storage, Docker-ready. Bring your own LLM keys — we never mark up token costs.

Simple, transparent pricing

Start free. Upgrade when you need more.

Frequently asked questions

Which LLMs can I use?+

Any OpenAI-compatible endpoint: OpenAI, Groq, OpenRouter, Together, or a local model via Ollama. You bring your own API key in Settings.

What is a crew run?+

A crew run lets several agents work the same task in sequence. Each agent sees all previous responses, so you can build research → write → critique loops automatically.

Do my LLM keys stay private?+

Yes. Each user's LLM configuration is stored per-account and never shared. If you self-host, everything stays on your server.

Can I self-host this?+

Absolutely. It's a single Node.js app with no database required. Set your Stripe keys to enable paid upgrades, or leave them out and run it free-only.

Loved by builders and teams

"Replaced three separate tools with one self-hosted platform. My team collaborates on agents and I control the billing."

"Owns my data, runs on my server, and the API keys let me embed agents into my own product."
